Sinton, TxQ.Frost damage to potted plants
Outdoor plants in the South. Usually, when we have a chance of freeze, besides watering and covering the flower beds, our potted plants are safe up against the house, 6-12 feet under a patio covering. This year we went down to 24 degrees for approximately 6+ hours. What to do about corn plants with leaves drooping and gray-green, and a schefflera burned brown? Most of those plants are alive, but the corn plants look very sad.

Certified ExpertA.First, make sure the plants aren't further damaged by any future freezes. If cold weather is coming, move the plants indoors if possible. If not, try to cover them with dry blankets or an upside-down trash can if possible.
Avoid pruning the damaged plants until spring. Plants can often recover from freeze damage, but they need time. If they start growing again in the spring, you'll be able to see which parts are alive and which are dead and prune accordingly. Avoid overwatering them until they recover, because damaged plants often use less water. Also see these articles:

February 25, 2017A.Apply sulphur or copper based fungicides at the first signs of disease.
Spray all parts of the plants throughly and repeat every 7 to 10 days-up until harvest.
Work on prevention by planting disease resistant varieties. Open and prune plants to help with air circulation. Remove and dispose of diseased foliage.
Use tools that have been cleaned with alcohol. Water in the am hours so leaves can dry and use soaker hoses.
Use slow release organic fertilizers to avoid excess nitrogen.
Destroy all remains of plant material after harvest, never compost diseased plant material.Was this answer useful?00 - Answered by

33043Q.buds are yellow and fall off
A lot of my buds are yellow and fall off, WHY! Was told over watering does it. It is not pot bound. It is in a very large container.

Certified ExpertA.Bud drop in many plants can be caused by overwatering. If the container your plant is in is very large, overwatering is actually the most likely explanation. Plants in too-large containers can suffer from root damage and many other overwatering-related problems because the soil stays wet too long in a large container.
Other problems that can cause bud drop include pests on the plant or underwatering (if it's underwatered, the plant will appear wilted but they perk up when you water it).

what causes leaves to turn yellow
- Answered by
Downtoearthdigs on
May 14, 2017A.This could depend on the type of plant you are referring too.
Yellow leaves can indicate a watering issue; too much or too little, environmental stresses, temperature fluctuations, pests, fungus disease, sun scorch, nutrition issues, excess salts in soil, to name a few.
