What is the best way to water my Pigweed?
To water Pigweed, you can use a garden hose with a spray nozzle, a watering can, or just about any other common watering tool. Generally, Pigweed is not too picky about how they receive their water, as they can live off of rainwater, tap water, or filtered water. Often, you should try not to water this plant from overhead, as doing so can damage the leaves and flowers and may lead to disease as well. At times, the best method for watering this plant is to set up a drip irrigation system. These systems work well for Pigweed as they apply water evenly and directly to the soil. For one Pigweed that grows in a container, you can use a similar watering approach while changing the tools you use. To water a container-grown Pigweed, use a cup, watering can, or your tap to apply water directly to the soil.

What should I do if I water my Pigweed too much or too little?
The remedy for underwatering Pigweed is somewhat obvious. When you notice that your plant lacks moisture, simply begin watering it on a more regular basis. The issue of overwatering can be a much more dire situation, especially if you fail to notice it early. When your Pigweed is overwatered, it may contract diseases that lead to its decline and death. The best way to prevent this outcome is to choose a proper growing location, one that receives plenty of sunlight to help dry the soil and has good enough drainage to allow excess water to drain rather than pooling and causing waterlogged soils. If you overwater your Pigweed that lives in a pot, you may need to consider changing it to a new pot. Your previous container may not have contained soil with good drainage or may not have had sufficient drainage holes. As you repot your overwatered Pigweed, make sure to add loose soils and to use a pot that drains efficiently.
Read More more
How often should I water my Pigweed?
Pigweed needs water regularly throughout the growing season. Beginning in spring, you should plan to water this plant about once per week. As the season presses on and grows warmer, you may need to increase your watering rate to about two to three times per week. Exceeding at this rate can be detrimental to your Pigweed. With that said, you should also ensure that the soil in which your Pigweed grows remains relatively moist but not wet, regardless of how often you must water to make that the case. Watering Pigweed that lives in a pot is a bit different. Generally, you'll need to increase your watering frequency, as the soil in a pot can heat up and dry out a bit faster than ground soil. As such, you should plan to water a container-grown Pigweed a few times per week in most cases, versus just once per week for an in-ground plant.

How much water does my Pigweed need?
There are a few different ways you can go about determining how much water to give to your Pigweed. Some gardeners choose to pick their water volume based on feeling the soil for moisture. That method suggests that you should water until you feel that the first six inches of soil have become moist. Alternatively, you can use a set measurement to determine how much to water your Pigweed. Typically, you should give your Pigweed about two gallons of water per week, depending on how hot it is and how quickly the soil becomes dry. However, following strict guidelines like that can lead to overwatering if your plant requires less than two gallons per week for whatever reason. When growing Pigweed in a container, you will need to use a different method to determine how much water to supply. Typically, you should give enough water to moisten all of the layers of soil that have become dry. To test if that is the case, you can simply stick your finger in the soil to feel for moisture. You can also water the soil until you notice a slight trickle of excess water exiting the drainage holes of your pot.

How can I tell if i'm watering my Pigweed enough?
It can be somewhat difficult to avoid overwatering your Pigweed. On the one hand, these plants have relatively deep roots that require you to moisten the soil weekly. On the other hand, Pigweed are plants that are incredibly susceptible to root rot. Along with root rot, your Pigweed may also experience browning as a result of overwatering. Underwatering is far less likely for your Pigweed as these plants can survive for a while in the absence of supplemental watering. However, if you go too long without giving this plant water, it will likely begin to wilt. You may also notice dry leaves.
Read More more
How should I water my Pigweed through the seasons?
You can expect your Pigweed’s water needs to increase as the season moves on. During spring, you should water about once per week. Then, as the summer heat arrives, you will likely need to give a bit more water to your Pigweed, at times increasing to about three times per week. This is especially true of Pigweed that grow in containers, as the soil in a container is far more likely to dry out faster than ground soil when the weather is warm. In autumn, while your Pigweed is still in bloom, it may need a bit less water as the temperature has likely declined, and the sun is no longer as strong as it was in summer.
Read More more
How should I water my Pigweed at different growth stages?
Pigweed will move through several different growth stages throughout the year, some of which may require more water than others. For example, you will probably start your Pigweed as a seed. While the seed germinates, you should plant to give more water than your Pigweed will need later in life, watering often enough to maintain consistent soil moisture. After a few weeks, your Pigweed will grow above the soil and may need slightly less water than at the seedling phase. Then, once this plant is mature, you can begin to use the regular watering frequency of about once per week. As flower development takes place, you may need to give slightly more water to aid the process.

What's the difference between watering Pigweed indoors and outdoors?
There are several reasons why most Pigweed grow outdoors rather than indoors. The first is that these plants typically grow to tall. The second reason is that Pigweed needs more daily sunlight than most indoor growing locations can provide. If you are able to provide a suitable indoor growing location, you may find that you need to give your Pigweed water a bit more often than you would in an outdoor growing location. Part of the reason for this is that indoor growing locations tend to be a lot drier than outdoor ones due to HVAC units. The other reason for this is that soil in containers can dry out relatively quickly as well compared to soil in the ground.

Basic Care Guide
Lighting
Full sun
Pigweed is a sunlight-loving plant that flourishes under ample natural light situations. It originated in habitats predominated by abundant luminosity. Inadequate light exposure might hinder its growth, while overly abundant light may cause harm. But, it usually handles extremes quite well.
Best Sunlight Practices
Transplant
6-12 inches
Transplant pigweed during the window when winter's chill gives way to gentler days, typically from the awakening of verdant landscapes to when the sun climbs higher. Choose a bright, well-draining spot and enrich with organic matter to welcome pigweed's robust growth.

Chinese mugwort
Chinese mugwort
Chinese mugwort, a member of the daisy family, closely resembles its relative, the Common mugwort (Artemisia vulgaris). However, chinese mugwort has a more intense aroma, which is how the two are distinguished.It can be toxic to highly toxic if consumed, and even handling can cause skin irritation or allergy reactions.
Chinese violet
Chinese violet
Chinese violet (Asystasia gangetica) is an erect or climbing plant that can grow to be 91 cm tall. It has weak, hairy stems. It is an invasive plant with seeds that disperse and spread aggressively. Chinese violet is native to Africa but grows on nearly every continent.
Arrowleaf sida
Arrowleaf sida
Arrowleaf sida (Sida rhombifolia) is a perennial plant with delicate yellow blooms on stiff, almost woody stems. The stems are used to make brooms, giving it the common name "broom jute." It is also used to make cord and twine.
Orchid tree
Orchid tree
Orchid tree (Bauhinia variegata) is a partially deciduous shrub-like tree that can grow from 6 to 8 m tall. Large fragrant flowers resembling orchids blossom from winter to spring. The colors of the flowers range from orchid purple to light pink all in the same blossom. A fast-growing tree that blooms best in full sun makes a spectacular street tree when grown in warm climates.
Chinese silver grass
Chinese silver grass
Chinese silver grass is a perennial grass that can grow 91 to 213 cm. It forms dense clumps from an underground rhizome. The chinese silver grass is grown mainly as an ornamental grass, with silvery leaves and flowers that vary in color based on the cultivar. Be careful where you plant this type of grass; in some zones it can become invasive.
Bradford pear
Bradford pear
The bradford pear is native to China but is considered invasive in the U.S. and Australia. Although it does not self-pollinate, it can become invasive by hybridizing with other plants to create fertile fruits that may seed in natural areas. The bradford pear creates large populations of fruits that are spread by birds and animals, readily rooting in disturbed areas. It also forms thick colonies that may compete with other native species for natural resources. Alternative plants include the Trident Maple and the Serviceberry. The bradford pear can be controlled by manually pulling young plants, and a range of herbicides such as oil-based herbicides, foliar herbicides, and both basal bark and stump treatments. It is important to remove seed sources as the weed can reinvade areas where it has been previously removed.
Poison ivy
Poison ivy
In pop culture, poison ivy is a symbol of an obnoxious weed because, despite its unthreatening looks, it gives a highly unpleasant contact rash to the unfortunate person who touches it. Still, it is commonly eaten by many animals, and the seeds are a favorite with birds. The leaves turn bright red in fall. Its sister species, Western poison ivy (Toxicodendron rydbergii), is not considered to be invasive in the United States, but is noxious in Australia and New Zealand.
Pokeweed
Pokeweed
Although its berries look juicy and tempting, the fruits and the root of pokeweed are toxic and should not be eaten. Pokeweed is considered a pest species by farmers but is nevertheless often grown as an ornamental plant. Its berries can be made into pokeberry ink as well.

View more
Indoor plants require adequate lighting for optimal growth. When natural sunlight is insufficient, particularly in winter or in less sunny spaces, artificial lights offer a vital solution, promoting faster, healthier growth.
1. Choose the right type of artificial light: LED lights are a popular choice for indoor plant lighting because they can be customized to provide the specific wavelengths of light that your plants need.
Full sun plants need 30-50W/sq ft of artificial light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft.
2. Determine the appropriate distance: Place the light source 12-36 inches above the plant to mimic natural sunlight.
3. Determine the duration: Mimic the length of natural daylight hours for your plant species. most plants need 8-12 hours of light per day.
Important Symptoms
Symptoms of Insufficient Light in %s
Pigweed, a plant that thrives in full sunlight, is commonly grown outdoors with ample sunlight. When cultivated indoors with inadequate light, it may exhibit subtle symptoms of light deficiency.
View more
(Symptom details and solutions)
Small leaves
New leaves may grow smaller in size compared to the previous ones once they have matured.
Leggy or sparse growth
The spaces between leaves or stems of your Pigweed may become longer, resulting in a thin and stretched-out appearance. This can make the plant look sparse and weak, and it may easily break or lean due to its own weight.
Faster leaf drop
When plants are exposed to low light conditions, they tend to shed older leaves early to conserve resources. Within a limited time, these resources can be utilized to grow new leaves until the plant's energy reserves are depleted.
Slower or no new growth
Pigweed enters a survival mode when light conditions are poor, which leads to a halt in leaf production. As a result, the plant's growth becomes delayed or stops altogether.
Lighter-colored new leaves
Insufficient sunlight can cause leaves to develop irregular color patterns or appear pale. This indicates a lack of chlorophyll and essential nutrients.
Solutions
1. To ensure optimal growth, gradually move plants to a sunnier location each week, until they receive at least 6 hours of direct sunlight daily. Use a south-facing window and keep curtains open during the day for maximum sunlight exposure and nutrient accumulation.2. To provide additional light for your plant, consider using artificial light if it's large or not easily movable. Keep a desk or ceiling lamp on for at least 8 hours daily, or invest in professional plant grow lights for ample light.
Symptoms of Excessive light in %s
Pigweed thrives in full sun exposure and can tolerate intense sunlight. With their remarkable resilience, symptoms of sunburn may not be easily visible, as they rarely suffer from it.
View more
(Symptom details and solutions)
Chlorosis
Chlorosis is a condition where the plant's leaves lose their green color and turn yellow. This is due to the breakdown of chlorophyll from excessive sunlight, which negatively affects the plant's ability to photosynthesize.
Sunscald
Sunscald occurs when the plant's leaves or stems are damaged by intense sunlight exposure. It appears as pale, bleached, or necrotic areas on the plant tissue and can reduce the plant's overall health.
Leaf Curling
Leaf curling is a symptom where leaves curl or twist under extreme sunlight conditions. This is a defense mechanism used by the plant to reduce its surface area exposed to sunlight, minimizing water loss and damage.
Wilting
Wilting occurs when a plant loses turgor pressure and its leaves and stems begin to droop. Overexposure to sunlight can cause wilting by increasing the plant's water loss through transpiration, making it difficult for the plant to maintain adequate hydration.
Leaf Scorching
Leaf scorching is a symptom characterized by the appearance of brown, dry, and crispy edges or patches on leaves due to excessive sunlight. This can lead to a reduction in photosynthetic capacity and overall plant health.
Solutions
1. Move your plant to the optimal position where it can receive abundant sunlight but also have some shade. An east-facing window is an ideal choice as the morning sunlight is gentler. This way, your plant can enjoy ample sunlight while reducing the risk of sunburn.2. It is recommended to trim off any completely dehydrated or withered parts of the plant.
