Why are my seedlings leaves curling up?

Last Updated: 4th June, 2020

Curled, crumbly leaves
Cause: Even a few hours without water can slow a seedlings' growth and after a day the plant may begin to curl its leaves to conserve moisture. Hot grow lights and the dry air inside heated homes can rapidly dehydrate plants, too.

Considering this, why are my leaves curling up?

When the the serrated edges of marijuana leaves curls or tipped up like that, it's often a sign of temperature stress, overwatering/root problems or extreme humidity levels. If this is happening to the plants which are closest to your grow light, that's a hint that the problem may be temperature related.

Also Know, what's wrong with my seedlings? If the stems of your little seedlings start to get thin at the bottom, if you see spots on their leaves, and/or if they simply fall over and die, they may have damping off. The sight of mold as your seedlings emerge from the soil may also be a symptom. As with mold (more below), be sure to have good air circulation.

Subsequently, one may also ask, how do you fix sagging seedlings?

Stick an index finger 1 or 2 inches into the plant's soil. If it feels dry, the plant needs water. If the soil feels moist, another problem is causing the wilting, such as over-watering, too much wind, very bright sunlight, pests or disease. Move the wilted plant out of the sun, if possible.

Why are my seedlings falling over?

Leggy seedlings happen for the same reason crooked houseplants happen. The plant grows towards the light and, since the light is too far away, the plant tries to accelerate its height to get close enough to the light to survive. Third, seedlings that are falling over can be more prone to disease and pests.

How do you treat leaf curl?

Treatment. Leaf curl can be controlled by applying sulfur or copper-based fungicides that are labeled for use on peaches and nectarines. Spray the entire tree after 90% of the leaves have dropped in the fall and again in the early spring, just before the buds open.

What does it mean when a plant's leaves start to curl?

When the lower leaves curl under, make sure you aren't overwatering the plant. The soil should never be soggy. Allow the top inch of soil to dry between waterings, and then give the plant as much water as the soil can hold. Overwatering and leaving the plant sitting in a saucer of water can lead to root rot.

How often should I water seedlings?

Until seeds have sprouted, keep the seed bed moist, never allowing it to dry out. Water with a fine-spray hose nozzle or watering can which will provide a fine misty spray and not wash away the soil. Water often enough (usually about once a day) so that the soil surface never dries out, but remains constantly moist.

How do you fix overwatering?

Wilted, overwatered plants are not always a lost cause.
  1. Move your plant to a shady area even if it is a full-sun plant.
  2. Check your pot for proper drainage and, if possible, create additional air space around the roots.
  3. Water only when the soil is dry to the touch, but do not let it get too dry.
  4. Treat with a fungicide.

How do you fix over watered plants?

How to fix overwatered plants. Let the soil dry out in the overwatered pot then lift the plant from the container, you will want to remove as much soil away from the roots as you can so you can inspect the roots. Trim off dead, damaged or unhealthy-looking roots so that only white ones remain.

How long does it take for an overwatered plant to heal?

Some genetics are weak and are not strong enough to recover from watering too much. It's when the plant has reached extreme stress. I have seen both over watered, and under-watered plants recover. Until 4-7 days later just slowly start to die.

Can you fix leggy seedlings?

If the soil is warm enough and the seedlings are mature enough to be transplanted, harden them off and get them outside in the sun to keep them from growing leggier. If you have leggy tomato seedlings, the best way to correct them is to repot them (or transplant them) and bury the stems up to the lowest set of leaves.

Can seedlings recover from damping off?

There is no cure for damping off, once it occurs. The tiny seedlings die so quickly, you probably would not have time to help them if you could. That's why it is important to try and avoid the problem altogether, with the following prevention practices. Damping off spreads rapidly.

  2. Trim your plant. If there is damage to the roots, trim back the leaves.
  3. Move your plant. Is your plant getting too much sun?
  4. Water your plant.
  5. Feed your plant.

Aniol Landgrafe


Can you overwater seedlings?

In particular, seedlings need the oxygen that their roots obtain from the soil. Waterlogged plant roots are blocked and unable to absorb oxygen. If you find an overwatered seedling, act quickly. The longer the oxygen is cut off, the more damage occurs to the roots.

Lorretta Fischelmanns


How do I know if my seedlings are healthy?

As the seedling gets a bit older, the serrated leaves should grow and more serrated leaves should sprout along with them. If you've gotten to this stage, it's very likely you have a healthy growing seedling!

Will droopy leaves recover?

Water plants more frequently if temperatures in your area are extremely hot; a plant with drooping leaves from heat will recover within hours. If droopy leaves or flowers result from frost damage, the plant needs to recover on its own.

Rosalinda Picornell


Why do my plants droop after watering?

Over-Watering. Problem: After watering, your plants start drooping. Usually the droopy leaves will feel firm and appear curled down (the whole leaf will be curled, not just the tips, which is often a sign of nitrogen toxicity). Overwatering does not always mean you've been giving the plant too much water.

Why are my orchid leaves limp and wrinkled?

This orchid has lost its roots, probably due to overwatering, and cannot take up water. Shriveled leaves indicate a lack of water to plant tissue. If they appear a healthy white or green and are plump, and the medium is in good shape, suspect underwatering, especially if the roots are white and the pot is very light.

Can you bring a plant back to life?

The answer is yes! First and foremost, the dying plant's roots must be alive to have any chance of coming back to life. It's even better if your plant stems still show signs of green. To get started, trim back any dead leaves and some foliage, especially if the majority of the roots are damaged.

Yane Andreson


How do you know when seedlings are dead?

If you do see brown, work your way down the plant stem, too. Try the scratch test with a lower twig or lower down the stem. The plant may show signs of life as you near the roots. If it does, cut off the dead stems an inch or two above the growth.

When should I give my seedlings nutrients?

The best time to give the first nutrient feeding is when your plant has 3 nodes or 3 sets of fan leaves. At this point the plant can handle a low dosage of nutes. I always start with 1/4 strength of what the feeding chart recommends for the first feeding.
