What is the best way to water my Pennsylvania everlasting?
When watering the Pennsylvania everlasting, you should aim to use filtered water that is at room temperature. Filtered water is better for this plant, as tap water can contain particles that are harmful to its health. The reason that the water should be at room temperature or slightly warmer is that the Pennsylvania everlasting comes from a warm environment, and cold water can be somewhat of a shock to its system. Also, you should avoid overhead watering for this plant, as it can cause foliage complications. Instead, simply apply your filtered room temperature water to the soil until the soil is entirely soaked. Soaking the soil can be very beneficial for this plant as it moistens the roots and helps them continue to spread through the soil and collect the nutrients they need.

What should I do if I water my Pennsylvania everlasting too much or too little?
Both overwatering and underwatering will be detrimental to the health of your Pennsylvania everlasting, but overwatering is a far more common issue. When this species receives too much water, its stems and leaves may begin to wilt and turn from green to yellow. Overwatering over a prolonged period may also lead to diseases such as root rot, mold, and mildew, all of which can kill your plant. Underwatering is far less common for the Pennsylvania everlasting, as this plant has decent drought tolerance. However, underwatering remains a possibility, and when it occurs, you can expect to find that the leaves of your Pennsylvania everlasting have become brittle and brown.
It is crucial that you notice the signs of overwatering as soon as possible when caring for your Pennsylvania everlasting. Some of the diseases that arise from overwatering, such as root rot, may not be correctable if you wait too long. If you see early signs of overwatering, you should reduce your watering schedule immediately. You may also want to assess the quality of soil in which your Pennsylvania everlasting grows. If you find that the soil drains very poorly, you should replace it immediately with a loose, well-draining potting mix. On the other hand, if you find signs that your Pennsylvania everlasting is receiving too little water, all you need to do is water more regularly until those signs have subsided.

How often should I water my Pennsylvania everlasting?
If your plant is in a pot. The most precise way to decide whether your Pennsylvania everlasting needs water is to plunge your finger into the soil. If you notice that the first two to three inches of soil have become dry, it is time to add some water.
If you grow your Pennsylvania everlasting outdoors in the ground, you can use a similar method to test the soil. Again, when you find that the first few inches of soil have dried out, it is time to add water. During the spring and early fall, this method will often lead you to water this plant about once every week. When extremely hot weather arrives, you may need to increase your watering frequency to about twice or more per week. With that said, mature, well-established the Pennsylvania everlasting can show an admirable ability to withstand drought.

How much water does my Pennsylvania everlasting need?
When it comes time to water your Pennsylvania everlasting, you should not be shy about how much water you give. With the first two to three inches of soil dry, this plant will appreciate a long and thorough watering. Supply enough water to soak the soil entirely. The amount of water you add should be enough to cause excess water to flow through the drainage holes at the bottom of your pot. If you don’t see excess water draining from the pot, you have likely underwatered your plant. But do not let the water accumulate inside the soil, which will be very dangerous to the plant as well. Alternatively, a lack of water draining through the pot could indicate poorly draining soils, which is detrimental to the health of this plant and should be avoided. If the plant is outside, 1 inch of rain per week will be sufficient.

How should I water my Pennsylvania everlasting at different growth stages?
The water needs of the Pennsylvania everlasting can change depending on growth stages as well. For example, when your Pennsylvania everlasting is in the first few years of its life, or if you have just transplanted it to a new growing location, you will need to give more water than usual. During both of those stages, your Pennsylvania everlasting will put a lot of energy towards sprouting new roots that will then support future growth. For those roots to perform their best, they need a bit more moisture than they would at a more mature phase. After a few seasons, your Pennsylvania everlasting will need much less water. Another growth stage in which this plant may need more water is during the bloom period. Flower development can make use of a significant amount of moisture, which is why you might need to give your Pennsylvania everlasting more water at this time.

How should I water my Pennsylvania everlasting through the seasons?
The Pennsylvania everlasting will have its highest water needs during the hottest months of the year. During the height of summer, you may need to give this plant water more than once per week, depending on how fast the soil dries out. The opposite is true during the winter. In winter, your plant will enter a dormant phase, in which it will need far less water than usual. In fact, you may not need to water this plant at all during the winter months. However, if you do water during winter, you should not do so more than about once per month. Watering too much at this time will make it more likely that your Pennsylvania everlasting will contract a disease.

What's the difference between watering my Pennsylvania everlasting indoors and outdoors?
It is most common to grow the Pennsylvania everlasting indoors for any gardener that does not live in temperate and tropical regions. Those gardeners should consider the fact that soil in a container can dry out a bit faster than ground soil. Also, the presence of drying elements such as air conditioning units can cause your Pennsylvania everlasting to need water on a more frequent basis as well. if you planted it outside. When that is the case, it’s likely you won’t need to water your Pennsylvania everlasting very much at all. If you receive rainfall on a regular basis, that may be enough to keep your plant alive. Alternatively, those who grow this plant inside will need to water it more often, as allowing rainwater to soak the soil will not be an option.

Common Pests & Diseases

Common issues for Pennsylvania everlasting based on 10 million real cases
Flower withering
Flower withering Flower withering
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Solutions: If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible. For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface. In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well. If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Aphids
Aphids Aphids
Aphids
Aphids are small, pear-shaped insects that come in a variety of semi-translucent colors. They suck sap from plants.
Solutions: Aphids can be controlled with physical, biological, and chemical methods. For less severe cases: Dip a cloth in soap water and use it to wipe/rub off all the aphids from plants. Use a hose with a good stream of water to spray them off. Introduce beneficial insects such as ladybugs and lacewings. For severe cases: Spray plants with a diluted mix of neem oil and insecticidal soap (follow label instructions). Apply in the evening or on a cloudy day to avoid burning plants. Remove and dispose of infected plants or plant parts. Surrounding plants should also be treated to fully control the problem.
Nutrient deficiencies
Nutrient deficiencies Nutrient deficiencies
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Solutions: There are several easy ways to remedy the nutrient deficiencies in soils. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.
Solutions

Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Aphids
plant poor
Aphids
Aphids are small, pear-shaped insects that come in a variety of semi-translucent colors. They suck sap from plants.
Overview
Overview
Aphids, also known as plant lice, can appear on almost any garden plant. These pests are tear-drop shaped, soft-bodied, and 3 mm or less in size.
Aphids can occur in all seasons, but they reproduce more quickly in warmer weather. Therefore, infestations are likely to become severe in late spring through early fall.
These pests feed on plants including trees, shrubs, vegetables, and flowers. While aphids feed on a large variety of plants, small plants are most susceptible to extreme damage. Aphids are more likely to occur on plants that are unhealthy due to insufficient light, nutrients, or watering problems, plants that have been excessively fertilized with nitrogens, and those that are in shock from pruning or transplanting.
Aphids are easy to control if they are caught early. If not treated early on, populations can quickly grow and cause major damage. In severe cases, entire plants may die.
Symptom Analysis
Symptom Analysis
Aphids are often seen before they have had a chance to do a lot of damage. These insects can be found in clusters under the leaves or on stems. They may be green, brown, white, yellow, or white.
Aphids secrete a sugary substance on plants known as "honeydew." While it is not harmful to the plant, it may be a telltale sign that these pests are present, and if left on the plant it can cause a black fungus known as sooty mold to take hold.
Aphids damage appears as many small dots known as stippling. If the pests are not removed, leaves may turn yellow or die. Leaves and stems may also become twisted.
A large number of ants in the area may also indicate an aphids problem. Ants take care of aphids in order to eat the honeydew that they secrete.
Solutions
Solutions
Aphids can be controlled with physical, biological, and chemical methods.
For less severe cases:
  • Dip a cloth in soap water and use it to wipe/rub off all the aphids from plants.
  • Use a hose with a good stream of water to spray them off.
  • Introduce beneficial insects such as ladybugs and lacewings.
For severe cases:
  • Spray plants with a diluted mix of neem oil and insecticidal soap (follow label instructions). Apply in the evening or on a cloudy day to avoid burning plants.
  • Remove and dispose of infected plants or plant parts.
Surrounding plants should also be treated to fully control the problem.
Prevention
Prevention
Prevention steps include the following:
  • Avoid buying and transplanting plants with any sign of aphids on them.
  • Keep gardens weeded and remove debris from around plants.
  • Plant a wide diversity of plants to provide food and habitat for beneficial insects that eat aphids. These insects include ladybeetles, lacewings, and minute pirate bugs.
  • Avoid using broad-spectrum pesticides that can kill beneficial insects that eat aphids.
  • Release beneficial insects such as ladybugs and lacewings to prevent large aphids outbreaks.
  • Regularly check for aphids and remove them when they first appear. This is especially important in enclosed areas like greenhouses.
  • Apply a balanced fertilizer in the recommended amount to avoid over-fertilizing.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
  1. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
  2. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.

Prevention
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
  1. Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
  2. Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
  3. Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

Weed Control

Weeds
Pennsylvania everlasting is a weed that grows In the U.S., principally along the eastern seaboard up to Massachusetts, and in the southern coastal states, along with Texas and California. It is often found in lawns and disturbed soil areas. It does not appear on any invasive species state or national list. However, this species reproduces only by seed, which are easily dispersed by the wind into new, unwanted locations. The weed is aesthetically highly unappealing and is not typically considered a garden plant. Removal methods for the weed would be by hand, being careful to include its roots, as well as application of an herbicide.
How to Control it
Once the weeds start to flower and fructify, it will be difficult to control them effectively. In fact, the best time to remove weeds is before flowering and fructification because the seeds will spread rapidly after that. So, it is necessary to remove weeds more often and to take precautions in advance next year. Mulching: During the seed stage, covering with sawdust, straws or black mulches to effectively inhibit seed germination and the growth of the seedling. Generally, this method is used in winter or spring to inhibit the germination of weed in the soil. If the weeds have already flowered and fructified, this method can be used to isolate the seeds and the soil to prevent the seeds from falling into the soil. Pulling out: Before the weeds fructify, wear gloves or use tools to pull them out. If it is difficult to pull out weed due to dry soil, adding water to the soil helps to make it easy to remove the roots thoroughly. After pulling out the weed, deep tillage can be adopted to remove the residual roots. This method is especially effective for weeds that are in the seedling stage. Pruning: Pruning weeds before they fructify can effectively control the propagation of weeds, especially for annual weeds. Frequent pruning can inhibit the growth and fructification of weeds and effectively them in the same year. Plowing: Before cultivation, plow the soil, collect and discard the roots of perennial weeds, then expose them to the sun or bury them deeply. It can also be used for retting organic fertilizer and composting. Chemical control: Using appropriate herbicides can effectively remove the weed from the area. Note: When removing weeds, it is necessary to wear gloves to avoid direct contact with the weeds, especially for the ones that are poisonous, thorny and allergenic. When removing weeds at the flowering stage, special masks should be worn to prevent allergic reactions caused by the inhalation of pollen.

Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.

Flower withering
plant poor
Flower withering
Flowers may dry out due to a sudden change in environment or because the plant has completed its normal flowering period.
Overview
Overview
Flower withering occurs when flowers become weak, droopy, wilted, or faded until they can’t be revived. During withering, they begin to wrinkle and shrink until the flower becomes completely dry or dead.
Any flowers, regardless of the plant type or the climate they are grown in, are susceptible to withering. It is a worldwide problem across houseplants, herbs, flowering ornamentals, trees, shrubs, garden vegetables, and food crops.
Unlike wilting—which withering is often confused with—withering can be caused by different things and is often due to more than a lack of water. Withering can be fatal in severe cases.
Symptom Analysis
Symptom Analysis
Flower withering progresses from very mild cases to severe occurrences that kill the flower. The severity of the symptoms is related to the cause and how long the condition is allowed to progress before action is taken.
  • Wilted, droopy flowers
  • Petals and leaves begin to wrinkle
  • Brown papery streaks or spots appear on the petals and leaf tips
  • Flowerhead shrink in size
  • Petal color fades
  • Yellowing leaves
  • Complete death of the flower
Disease Cause
Disease Cause
The main causes of flower withering include natural age progress, lack of water, nutritional deficiencies, and bacterial or fungal diseases. It’s critical to determine the underlying cause when flower withering is noticed. This will guide the best course of action, if treatment is possible.
Check the soil for moisture and then closely examine the entire plant for signs of nutrient deficiencies. If neither of those appears to be the cause then cut open the stem below a flower. If a cross-section reveals brown or rust-colored stains it is safe to assume that this is a bacterial or fungal infection.
If the flower is nearing the end of its normal lifespan, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence, or cell aging and death. Cell division stops and the plant begins breaking down resources within the flower to use in other parts of the plant.
In all other cases, flower withering happens when the plant seals off the stem as a defense mechanism, stopping transport within the vascular system. This prevents further water loss through the flowers but also stops bacteria and fungi from moving to healthy parts of the plant. Once water and nutrient transport stops, the flower begins to wither and ultimately die.
Solutions
Solutions
If flower withering is a natural progression due to age, there is nothing that can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
For lack of water, immediately water the plant using room temperature rainwater, bottled spring water, or filtered tap water. Water container plants until excess water drains out the bottom; water in-ground plants until the soil is soaked but there isn’t standing water on the surface.
In the event of nutritional deficiencies, the best solution is to use a granular or water-soluble liquid fertilizer, and apply it to the soil at about half the recommended dosage. Keep it off the leaves and make sure granular products are watered into the soil well.
If the plant is infected with a bacterial or fungal pathogen, there is no course of treatment that cures the diseased plants. The best solution is to remove the infected plants and dispose of the plant material off-site. Do not put in a compost pile.
Prevention
Prevention
This is definitely one of those instances where prevention is more effective than cure. Here are some preventative measures for avoiding premature flower withering.
  • Water plants according to their needs -- either keep the soil slightly moist or allow the top inch or two to dry out before watering again.
  • Fertilize lightly on a consistent basis, depending upon the plant’s growth. Quick-growing plants and those that flower or develop fruit will need more frequent fertilizing than slow-growing plants.
  • Purchase plants that are certified disease- or pathogen-free.
  • Look for disease-resistant cultivars.
  • Isolate plants showing disease symptoms to prevent the spread to neighboring plants.
  • Practice good plant hygiene by removing any fallen plant material as soon as possible.

Aphids
plant poor
Aphids
Aphids are small, pear-shaped insects that come in a variety of semi-translucent colors. They suck sap from plants.
Overview
Overview
Aphids, also known as plant lice, can appear on almost any garden plant. These pests are tear-drop shaped, soft-bodied, and 3 mm or less in size.
Aphids can occur in all seasons, but they reproduce more quickly in warmer weather. Therefore, infestations are likely to become severe in late spring through early fall.
These pests feed on plants including trees, shrubs, vegetables, and flowers. While aphids feed on a large variety of plants, small plants are most susceptible to extreme damage. Aphids are more likely to occur on plants that are unhealthy due to insufficient light, nutrients, or watering problems, plants that have been excessively fertilized with nitrogens, and those that are in shock from pruning or transplanting.
Aphids are easy to control if they are caught early. If not treated early on, populations can quickly grow and cause major damage. In severe cases, entire plants may die.
Symptom Analysis
Symptom Analysis
Aphids are often seen before they have had a chance to do a lot of damage. These insects can be found in clusters under the leaves or on stems. They may be green, brown, white, yellow, or white.
Aphids secrete a sugary substance on plants known as "honeydew." While it is not harmful to the plant, it may be a telltale sign that these pests are present, and if left on the plant it can cause a black fungus known as sooty mold to take hold.
Aphids damage appears as many small dots known as stippling. If the pests are not removed, leaves may turn yellow or die. Leaves and stems may also become twisted.
A large number of ants in the area may also indicate an aphids problem. Ants take care of aphids in order to eat the honeydew that they secrete.
Solutions
Solutions
Aphids can be controlled with physical, biological, and chemical methods.
For less severe cases:
  • Dip a cloth in soap water and use it to wipe/rub off all the aphids from plants.
  • Use a hose with a good stream of water to spray them off.
  • Introduce beneficial insects such as ladybugs and lacewings.
For severe cases:
  • Spray plants with a diluted mix of neem oil and insecticidal soap (follow label instructions). Apply in the evening or on a cloudy day to avoid burning plants.
  • Remove and dispose of infected plants or plant parts.
Surrounding plants should also be treated to fully control the problem.
Prevention
Prevention
Prevention steps include the following:
  • Avoid buying and transplanting plants with any sign of aphids on them.
  • Keep gardens weeded and remove debris from around plants.
  • Plant a wide diversity of plants to provide food and habitat for beneficial insects that eat aphids. These insects include ladybeetles, lacewings, and minute pirate bugs.
  • Avoid using broad-spectrum pesticides that can kill beneficial insects that eat aphids.
  • Release beneficial insects such as ladybugs and lacewings to prevent large aphids outbreaks.
  • Regularly check for aphids and remove them when they first appear. This is especially important in enclosed areas like greenhouses.
  • Apply a balanced fertilizer in the recommended amount to avoid over-fertilizing.

Nutrient deficiencies
plant poor
Nutrient deficiencies
A lack of nutrients will cause a widespread yellowing of the leaves. The yellowing may begin at the base or top of the plant.
Overview
Overview
Nutrient deficiencies can be seen in many different ways on plants. Basically, the lack of nutrients will inhibit plant growth, produce weak stems and leaves, and leave plants open to infection from pests and diseases. Plants use the nutrients from the soil to help them with photosynthesis. This, in turn, produces healthy plant growth. Plants that lack adequate amounts of nutrients will look lackluster and unhealthy. Eventually, if this is not addressed, it will cause the plants to die. The most important nutrients that plants need are nitrogen, phosphorus, potassium, calcium, magnesium, and sulfur. Additionally, plants require small amounts of micronutrients such as iron, boron, manganese, zinc, copper, and molybdenum.
Symptom Analysis
Symptom Analysis
A common sign that plants are experiencing nutrient deficiencies is the yellowing of leaves. This may be an overall yellowing or leaves that are yellow but still have green veins. These leaves will eventually brown off and die.
Another sign is the loss of plant vigor. The plants may not be growing as well as they should or their growth may be stunted.
Below are some common symptoms that appear when plants are lacking in nutrients.
Nitrogen (N): Inner, older leaves yellow first. If the deficiency is severe, yellowing progresses outward to newer growth.
Potassium (K): Leaf edges may turn brown and crinkly, with a yellowing layer forming just inside of the edge. Older leaves tend to be impacted first.
Phosphorus (P): Lack of vigorous growth. Plants will appear stunted.
Zinc (Zn): Yellowing tends to occur first at the base of the leaf.
Copper (Cu): Newer leaves begin to yellow first, with older leaves yellowing only if the deficiency becomes severe.
Boron (B): Newer leaves are impacted first. Foliage may also become particularly brittle in cases of boron deficiency.
Disease Cause
Disease Cause
There are several factors that can lead to nutrient deficiencies, a situation where plants are not receiving the nutrients that they need. This could be because they are planted in nutrient-deficient soils, or that the soil's pH is too high or low. Incorrect soil pH can lock up certain nutrients, thus making them unavailable to plants. Lack of soil moisture can also be a problem, because plants need water to be able to absorb the nutrients from the soil.
Solutions
Solutions
There are several easy ways to remedy the nutrient deficiencies in soils.
  1. Use a water-soluble fertilizer. Fertilizers will include most or all of the macro and micro-nutrients the plants need to thrive. Adding some fertilizer to the soil will make those nutrients available and can combat deficiencies.
  2. Regularly apply organic fertilizer pellets. Organic fertilizers such as animal manures and bonemeal can supply plants with all the nutrients that they need to grow strong and healthy.
  3. Apply compost. Though not as finely tuned as artificial fertilizer, compost can nevertheless be rich in important nutrients and should be applied to the soil regularly.
  4. Apply nutrients via foliar application. In addition to supplementing the soil with nutrients, foliar fertilizer can be applied directly to the plant's leaves. Nutrients offered via foliar application are often taken up even quicker than those put in the soil, so the foliar application can be great for swiftly addressing specific deficiencies.
Prevention
Prevention
There are several easy ways to prevent nutrient deficiencies in plants.
  1. Regular fertilizing. Regular addition of fertilizer to the soil is one of the simplest and most effective ways to prevent deficiencies.
  2. Proper watering. Both over and under watering can adversely impact a plant's roots, which in turn makes it harder for them to properly take up nutrients.
  3. Testing the soil's pH. A soil's acidity or alkalinity will impact the degree to which certain nutrients are available to be taken up by plants. Knowing the soil's pH means it can be amended to suit the needs of the individual plants.

Weed Control

weed
Weeds
Pennsylvania everlasting is a weed that grows In the U.S., principally along the eastern seaboard up to Massachusetts, and in the southern coastal states, along with Texas and California. It is often found in lawns and disturbed soil areas. It does not appear on any invasive species state or national list. However, this species reproduces only by seed, which are easily dispersed by the wind into new, unwanted locations. The weed is aesthetically highly unappealing and is not typically considered a garden plant. Removal methods for the weed would be by hand, being careful to include its roots, as well as application of an herbicide.
How to Control it
Once the weeds start to flower and fructify, it will be difficult to control them effectively. In fact, the best time to remove weeds is before flowering and fructification because the seeds will spread rapidly after that. So, it is necessary to remove weeds more often and to take precautions in advance next year. Mulching: During the seed stage, covering with sawdust, straws or black mulches to effectively inhibit seed germination and the growth of the seedling. Generally, this method is used in winter or spring to inhibit the germination of weed in the soil. If the weeds have already flowered and fructified, this method can be used to isolate the seeds and the soil to prevent the seeds from falling into the soil. Pulling out: Before the weeds fructify, wear gloves or use tools to pull them out. If it is difficult to pull out weed due to dry soil, adding water to the soil helps to make it easy to remove the roots thoroughly. After pulling out the weed, deep tillage can be adopted to remove the residual roots. This method is especially effective for weeds that are in the seedling stage. Pruning: Pruning weeds before they fructify can effectively control the propagation of weeds, especially for annual weeds. Frequent pruning can inhibit the growth and fructification of weeds and effectively them in the same year. Plowing: Before cultivation, plow the soil, collect and discard the roots of perennial weeds, then expose them to the sun or bury them deeply. It can also be used for retting organic fertilizer and composting. Chemical control: Using appropriate herbicides can effectively remove the weed from the area. Note: When removing weeds, it is necessary to wear gloves to avoid direct contact with the weeds, especially for the ones that are poisonous, thorny and allergenic. When removing weeds at the flowering stage, special masks should be worn to prevent allergic reactions caused by the inhalation of pollen.

Name story

Pennsylvania everlasting
The specific epithet for pensylvanica is a misnomer because the plant is not native to Pennsylvania and only marginally introduced there. Since the flowers remain its beauty even when it is dry, it is then called Pennsylvania everlasting.
