Leaves are likely to droop more when air is dry as well as hot. High humidity on a hot summer day can reduce the quantity of water from roots needed by leaves. Wind can increase water needs and cause more drooping.

Wilting is the loss of rigidity of non-woody parts of plants. This occurs when the turgor pressure in non-lignified plant cells falls towards zero, as a result of diminished water in the cells. The rate of loss of water from the plant is greater than the absorption of water in the plant.

Generally, heat stress of a plant will show itself by wilting, which is a sure sign that water loss has taken place. If this is ignored, the condition will worsen, as the plants will eventually dry up, turning a crunchy brown before dying. In some cases, yellowing of the leaves may occur.

How to protect your plants in the summer heat

1. Keep soil moist. If you’re anticipating very hot temperatures during the day, watering your plants early in the morning will maintain moisture in the soil and avoid plant stress.
2. Mulching.
3. Anti-transpirants.
4. Potted plant care.
5. Shelter.

Move the wilted plant out of the sun, if possible. Set wilted container plants with dry soil in a sink or tray filled with water. Spray the plant’s foliage with water; misting can help rejuvenate the plant quickly. Provide protection from strong sun and heavy wind while the plant recovers.

Rescue Techniques for Wilting Plants

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.

Signs of Overwatered Plants: What to Look For Sign one: If a plant is overwatered, it will likely develop yellow or brown, limp leaves as opposed to dry, crispy leaves (which are actually a sign of too little water). Wilting leaves usually mean that root rot has set in and the roots can no longer absorb water.

Determine which by feeling the leaf showing browning: if it feels crispy and light, it is underwatered. If it feels soft and limp, it is overwatered. Yellowing leaves: Usually accompanied by new growth falling, yellow leaves are an indication of overwatering.

How to save a dying plant

1. Repot your plant. Use a high-quality indoor plant potting mix to revitalise your plant, and choose a pot that’s wider than the last one.
2. Trim your plant. If there’s damage to the roots, trim back the leaves.
3. Move your plant.
4. Water your plant.
5. Feed your plant.
6. Wipe your plant.

When you see dead leaves, dormant stems, or brown parts of leaves, cut them away. It’s fine to pluck dead leaves or stems with your hands when possible, just don’t pull too hard or you may damage the healthy part of your plant. For tougher stems or to remove brown leaf tips and edges, use scissors or pruning shears.

Plant tips can turn brown when they’re exposed to too much fertilizer and too many salts build up in the soil. When this happens to potted plants, tips turn brown from a condition known as fertilizer burn or tip burn. As a result, water-deprived plant tips turn brown.

So how do you know you have overwatered your plant? What does an overwatered peace lily look like? The peace lily will look like it’s starting to wilt and will discolor with yellow and brown leaves, grow slower than usual, and the roots will start to rot due to fungal infections in soggy conditions.

A yellow leaf on a house plant is unlikely to turn green again UNLESS the yellowing is caused by a nutritional deficiency, which if rectified, could cause the green colour to return. Usually though, say goodbye to the green. Hell, make your peace and put the whole leaf’s affairs in order.

The most common nutrient problem associated with chlorosis is lack of iron, but yellowing may also be caused by manganese, zinc, or nitrogen deficiencies. According to Schuster one way to separate iron deficiency from other deficiencies is to determine what foliage turned yellow first.

Generally, it’s safe to remove a few yellowed leaves from your plant. Removing yellow leaves keeps your plant looking healthy and your garden looking green. Removing yellow leaves can also reduce the risk of pests, which can gravitate to weaker plants.

These are classic symptoms of drought. This can be caused by over or under-watering your plants and even a few days of drought can cause leaves to turn yellow. Leaves will turn yellow and fall off relatively quickly if newly planted laurel are not watered enough during the growing season (normally March to October).

Nutritional deficiency – A yellowing bay laurel can be caused by a nutritional deficiency, particularly in iron. If a plant is not receiving enough iron it decreases Chlorophyll which is a vital component of photosynthesis, allowing plants to absorb energy from the sun. This results in yellow leaves at the edges.

How to make a cherry laurel shrub bushier

1. Prune hedging or specimen cherry laurels two or three times a year to promote bushiness, any time from April to September.
2. Select branches evenly distributed across the bush, and prune them back with secateurs to just above a leaf.

When you are planting a new Laurel hedge we always recommend using bone meal, this is a natural organic fertiliser that should be well mixed with the soil. One kilo of bone meal will be sufficient for a 15 metres of hedge planting.

Get your hand down into the soil around the roots and see if its dry or wet. If its dry, give it a full watering can then leave it ten minutes and try again. If its dry, repeat. With a newly planted hedge, you should be keeping it watered the first few summers until the roots spread into the surrounding soil.

As obvious as it sounds, your laurel may not be growing fast enough due to lack of water. If your laurel shrub is new, you should be regularly watering particularly in its first year of growth. We recommend that in the summer months you water: every 2 days if the soil is very dry and / or sandy.

The leaves of your laurel plants will quickly turn yellow and start to fall off if they are not watered enough (or if they are over-watered). Even a hot weekend in the summer can cause them to dry out so it is best to keep an eye on them every few days.

Laurel hedge plants can suffer from frost damage in Autumn, winter or Spring. Frost damage during the winter months can cause brown patches on established Laurels of all types and is usually at its worst when there is a very cold wind with no protective cover of snow to protect the winter foliage.
