Fruit Spot
Pathogenic infections can cause spots (typically black or brown) to appear on the fruit.
Solutions: Prune regularly - prune as a preventative measure as well as to remove any plants and plant parts affected by fruit Spot. Improve air circulation and drainage Fertilize as needed Spray applications - there are few programs that are effective at controlling fruit Spot for home growers, but the local cooperative extension may be able to provide information regarding potential chemical treatments if the disease is severe.
Underwatering
Leaves may wilt for a variety of reasons.
Solutions: The easiest (and most obvious) way to address underwatering is to fully hydrate the plant. However, this must be done carefully. A common mistake that many gardeners make is to douse their underwatered plants with water. This can overwhelm the roots of the plant and shock its system, something that can be even more damaging than the lack of water to begin with. Instead, water thoroughly and slowly, taking breaks to let the water slowly saturate through the soil to get to the roots. Use room temperature water, as cold water might be too much of a shock. In the future, shorten the time between waterings. A good rule of thumb is to check the soil around each plant daily. If it’s dry to at least two inches down, it’s time to water. If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Solutions: If the yellowing and drying of leaves and flowers is a natural progression due to age, nothing can be done to slow or stop the process. Once hormones within the plant begin the process of senescence, it’s irreversible.
Fruit Spot
Pathogenic infections can cause spots (typically black or brown) to appear on the fruit.
Overview
If there are brown or black spots on the unripened fruits of plants, there is a good chance that fruit Spot could be to blame. This is an informal term used to describe several types of diseases that all cause these same symptoms: unattractive spots on fruits and vegetables.
There are a few different culprits behind fruit Spot, including bacterial spot, bacterial speck, and other related diseases (like early blight). Here are some symptoms and potential solutions to consider.
Symptom Analysis
The symptoms of fruit Spot vary depending on which type of plant is affected as well as by which specific pathogen is to blame. Just about every type of plant can be affected by fruit Spot, including tomatoes, pears, plums, onions, strawberries, celery, peaches, and more.
Here are some examples of potential symptoms:
Small Fruit Spot
Small spots are most commonly associated with bacterial speck.
Spots may appear on fruits as well as leaves and other aboveground areas of the plant
Small black specks appear on infected fruits (spots are less than 1/16” in diameter)
Spots are raised with distinct margins, developing into sunken pits as the fruit matures
Fruit tissue near the spot stays green longer than the rest of the fruit
Spots are dark brown to black in color, with nearby spots often growing together
Large Fruit Spot
Large spots are often seen on plants suffering from bacterial spot, early blight, and related diseases.
Spots are large, sometimes larger than 1.3 cm
Some spots may look like targets with a brown to greyish coloration
Older spots are black and raised with lobed borders
Spots are superficial only, not penetrating into the seed cavity
Spots may turn into sunken pits, turning into craters as they get older
The skin of the fruit can be cracked and produce a water-soaked border
Some spots may ooze a gelatinous substance
Disease Cause
There are a few culprits behind the fruit Spot. These depend on the pathogen as well as the type of plant. Bacterial speck and bacterial spot are both common diseases that can affect tomatoes, ground cherries, and other plants.
Bacterial speck is caused by Pseudomonas syringae. First discovered in the United States in 1933, it is most common in tomatoes and nearby weeds but can affect other kinds of plants and their fruits, too. It is more prevalent in low temperatures (less than 24 ℃) and high moisture.
Bacterial spot is caused by Xanthomonas campestris pv. Vesicatoria. First discovered in Texas in 1912, this disease is more common in warm weather and conditions of high moisture.

Underwatering
Leaves may wilt for a variety of reasons.
Overview
Underwatering plants is one of the quickest ways to kill them. This is something that most gardeners are well aware of. Unfortunately, knowing exactly how much water a plant needs can be tricky, especially considering that underwatering and overwatering present similar symptoms in plants.
Therefore, it’s important to be vigilant and attentive to each plants’ individual needs.
Symptom Analysis
As mentioned earlier, overwatering and underwatering present similar symptoms in plants. These symptoms include poor growth, wilted leaves, defoliation, and brown leaf tips or margins. Ultimately, both underwatering and overwatering can lead to the death of a plant.
The easiest way to determine whether a plant has too much water or too little is to look at the leaves. If underwatering is the culprit, the leaves will look brown and crunchy, while if it’s overwatering, they will appear yellow or a pale green in color.
When this issue first begins, there may be no noticeable symptoms at all, particularly in hardy or drought-tolerant plants. However, they will begin to wilt once they start suffering from a lack of water. The edges of the plant’s leaves will become brown or curled. Soil pulling away from the edges of the planter is a telltale sign, or a crispy, brittle stem.
Prolonged underwatering can cause a plant’s growth to become stunted. The leaves might drop and the plant can be more susceptible to pest infestations, too.
Disease Cause
Underwatering is caused by, quite simply, not watering plants often or deeply enough. There is a heightened risk of underwatering if any of these situations apply:
Extreme heat and dry weather (when growing outdoors)
Grow lights or indoor lighting that is too bright or intense for the type of plant
Using fast-draining growing media such as sand

Aged yellow and dry
Natural aging can cause leaves to turn yellow and dry out.
Overview
Regardless of the type of plant or where it is grown, at some point, it will begin to aged yellow and dry. This is a natural, unavoidable process that happens when the plant has completed all of the steps in its life.
Annual plants go through this process at the end of a single growing season. Perennial plants live for multiple years, if not tens or hundreds of years, but will still ultimately exhibit these symptoms.
Symptom Analysis
When plants have progressed through their natural developmental stages and are nearing the end of their lifecycle, they begin showing signs of decline. Leaves will start to yellow and droop, and over time they turn papery brown and dry.
Once completely dry, the leaves begin to fall from the plant until the entire plant has dried out.
Disease Cause
At the end of its life, genetic coding within the plant increases the production of ethylene, a phytohormone that controls senescence or natural aging and death. Cell division stops, and the plant begins catabolizing resources to use in other parts of the plant.
As this happens, the tissues begin yellow and drying until the entire plant is desiccated and perishes.

Prevention
There are several ways to prevent both types of fruit Spot from affecting yields and harvests:
Rotate crops - do not plant the same kind of plant in the same spot each year, instead switching out locations every two to three years
Use disease-free seeds and transplants - using a hot water treatment to sterilize seeds before planting can also be effective
Irrigate early in the day to give plants time to dry off before nightfall
Avoid working around plants when they are wet
Control weeds
Remove debris or plow it under at the end of the growing season
Fertilize with higher amounts of nitrogen and use less calcium
Plant resistant cultivars when available
Do not clip plants when transplanting
Dispose of affected plant parts immediately (do not compost)

If a container plant is repeatedly drying out very quickly, repotting into a slower-draining container might be a good idea, too.
Prevention
Always check the soil before watering. If the top inch of soil feels moist, though not wet, the watering is perfect. If it’s dry, water it immediately. If it feels soggy, you avoid watering until it dries out a bit more.
Also, make sure the lighting is sufficient for the species. Plants grow faster and need more water when there is intense light or lots of heat. Being aware of these conditions and modifying them, if possible, is a good way to prevent underwatering. Many container plants are potted in soil mixtures mean to be well-draining. Adding materials that retain moisture, like compost or peat moss, can also prevent these symptoms.
Other tips to prevent underwatering include:
Choose pots with adequately-sized drainage holes
Avoid warm temperatures
Use large pots with additional soil (these take longer to dry out)
Avoid terracotta pots, which lose water quickly
