Why do leaves droop

As summer slowly melts into fall, temperatures are still reaching the high 90s and many plants wilt in the afternoon sun. Plants with big leaves, such as hydrangeas and angel trumpets, are often the first to get a little droopy in the hotter part of the day. There are two problems with watering in the afternoon. First, water that remains on the leaves of plants throughout the evening is more likely to invite disease problems. For example, hydrangeas and roses are highly susceptible to leaf spot diseases such as Cercospora, anthracnose or black spot.

Watering in the morning as the sun rises allows leaves to dry more quickly and minimizes these disease problems. It is even better to avoid wetting the leaves at all and just water the roots with a drip irrigation system. If you hand-water your plants, invest in a watering wand with a water breaker nozzle that can be used to apply water directly to the roots. Wilting is an adaption that many plants use to reduce water loss during the hottest part of the day.

A wilted leaf has less surface area exposed to sunlight and therefore will not lose water as quickly. In extreme cases with household plants, soil tightens away from the sides of the pot, so water runs through the space between the dried-out soil and the pot instead of wetting the root zone. This damages the roots, which makes them less capable of taking in water.

It's easy to want to increase watering to remedy droopy leaves, but sometimes this makes the situation worse. Overwatering a plant can cause roots to rot and prevent oxygen from reaching them.

The result is root death, which means that they no longer take up water to support the rest of the plant. Leaves droop as they die. You might think that your plant isn't getting enough water, but in this case, the reason for the drooping foliage is that too much water has smothered the roots. Adding more water will not help. When you move a plant, especially a larger established plant, you will damage a lot of roots. It is quite normal for such a plant to show wilting right after being moved.

It is quite common for people to water far too much after transplanting in order to try and fix the problem. Too much water does not help the problem. One solution is to move plants in spring and fall when the temperatures are lower and plants are not growing at full tilt. At these times of the year water evaporation from leaves is less and you get less wilting. If you do move a plant in summer, it will wilt much less if it is covered for a week or two so that it receives less sun light.

Over-watering a plant can cause the roots to rot. Some diseases can also cause roots to rot. With less roots, the plant wilts. Some people will then water the plant even more, causing even more root rot. Wilted plants should only be watered if the soil is dry. If the soil is not dry, it is not a water problem and watering can only make things worse. The short answer is YES. Occasional short term wilting will not do too much harm, but it is still not good for the plant.

Some people think that wilting is a natural phenomena in plants and it shows that they are conserving water. That is simply not true. When plants do not have enough water they go into crisis mode. They stop growing, they close stomata to conserve water and they shut down other vital processes. Wilting is a sign that the plant is in crisis mode. If this is due to a lack of water, the plant should be watered right away to reduce long term damage to the plant.

Some plants, like ligularia, which have very large thin leaves, wilt more easily than most plants. By mid-day my ligularia are all wilting even when grown in shade and in wet soil. By pm they are back to normal, showing fully stretched out leaves. Is this the best situation for these plants? But some plants are better able to survive the crisis than others and a few hours of wilting does not seem to cause permanent damage to ligularia. What research are you referencing?

I decided to move my full grown dahlias from my backyard to my front yard. I watered it afterwards. Hours later, the petals started to wilt. Will my dahlias recover or did I make a mistake? Great article. I am in Johannesburg, South Africa. In the last week I have noticed the leaves in 4 of my plants wilting.

I water each plant for about a minute three times a week. Is this too much water. The leaves are not yellow and to the touch feel moist. It was taken out before been given to me so I dont know how much damage was caused. I have planted it in a large pot In a part of my garden that has both lots of sun and shade. It was ok for a couple of days but now the leaves are yellowing and wilting and it doesnt look very well. Is there anything I can do to help it recover?

Thank you. On an April 26, , comment someone asked about covering transplants with a bucket for shade. A bucket in sun will cook the plants especially if it is a dark color or metal. Even a white PVC bucket gets too hot in the sun, but if that is all you have, then prop the bucket up on one side so a breeze can keep moving the hot air out. The container gets hot, but the air under it does not.

You also want to have air space between the bucket and ground. Please help! And is it okay to air dry the roots for 24 hours? Will it rebound from this. I have 2 new dianthus fruit punch. One us doing great and the other is nice and green but limp and weak feeling and it looks weak. My dahlia plant started wilting immediately after repotting. After two days the soil is still moist. May be over watering. How can i save it pls advise. How about for some plants and succulents that are wilted to cover them up with a bucket for a few days, to keep them out of the sun,.

Hi I transplanted raspberry canes and now the leaves are wilted and some are drying up? What should I do? Thanks in advance.

During the process I had to cut several large roots. Once the tree was removed it went directly into the prepared whole in the back yard. The tree is wilting today. Is there anything I can do to help the tree get through the transplant? Would it help to prune a large branch to help the water reach the main.

Hi there, I recently had some over crowding in one pot of my Pothos ivy so, even though they all seemed fine together, I decided to remove a few of the smaller plants to repot them and space out the larger ones. I did this once before and they all did splendidly well!! The leaves seem thin and droopy. Considering how fast it is going down hill should I maybe take it out and repot it?

Maybe I crammed the roots and damaged them? I fear if I do nothing it will surely be dead in a couple of days. Well, 2 more leaves died and the rest was following fast so…. I know a lot of these comments are about outdoor plants, but i woke up two days ago to find my rubber tree wilting.

Should I give it more water? I just planted two 6 foot Kwansan cherry trees, they started to wilt shortly after I planted them hours. The leaves are not yellowing just drooping but still dark green. Roots were in good condition. They are on west side of house, full sun and wind.

Should they be fertilized? I have three other Kwanzan cherrys 8ft tall been doing great for years. Any advise? They have just had a big shock and need some time to settle in. Just wait. Just repotted my Croton Petra a week ago and my water meter says it has plenty of water but the leaves are still wilting why. I have satin pothos when I got it, it was doing great!

But it had a little root rot I cut what I could off and spray peroxide to the roots to kill any fungus. Or is it dying the rest of the plant looks okay. Not nearly enough information to give an answer. Consider posting in our Facebook group and include pictures. I re-potted a peace lily around a week ago as the roots were starting to come through the bottom of the pot.

Hi, I bought a small ornamental pepper plant from the grocery store a few months back and it was doing great for a while. Eventually, all the peppers shriveled up and fell off but the leaves were growing.

Yesterday, it was doing great, but this morning, I woke up to all wilted leaves and watered it right away. How long will it take for them to perk up again? I started growing an apple tree from seed.
