The good news is that yes, your plant can recover from sunburn if it's not too bad. The bad news is that the sunburnt parts of the plant will never go away; it'll always have a scar if it does pull through.
Signs of sunburn on your plants (ouch!)
Instead of turning red like our skin does, the leaves turn yellow or white. The affected leaf yellows, turns brown and finally withers. The edges of the leaves often become completely dry. This happens especially when the sunburn is severe.
Once leaf scorch has occurred, there is no cure. The dehydrated portions of the leaf will not turn green again, but with proper water management, the plant may recover. Prevention of scorch needs to begin with winter watering.
Damaged leaves will not recover. Prune off damaged leaves and move the plant to a shadier place, or cover it with shade netting. Use fertilisers high in nitrogen to encourage the plant to replace the lost leaves. Prevention is always better than cure.
Sunburned leaves will eventually fall off on their own, but you could remove any leaves that have more than 50% damage now to improve the plant's overall look. You can also help the plant by fertilizing to support a flush of new growth.
Browning of leaf margins and/or yellowing or darkening of the areas between the main leaf veins are symptoms of leaf scorch. Due to environmental causes, leaves may dry, turn brown, and become brittle. Look for damage to trees and shrubs on the upper portion on the sunny, southern side, and on the windy side.
Stunted slow growth with yellowing leaves is a symptom of over-watering. Plants may suffer from leaf scorch or leaf burn. Water-soaked spots and blisters (Oedema) may appear on stems and leaves. The crown of the plant may rot.
The bark may show as an elongated canker (areas of dead bark) that appears sunken or discolored, followed by cracking and peeling of the bark. You'll find the damage on the south or southwest side of a tree. Wrapping your tree before winter on these thin barked trees may help prevent sunscald.
Removing leaf burn depends on a case-by-case basis. If a small part of the leaf is burned, but the plant is still getting water and functioning, it's best to just let it be. In more severe cases where the leaves are completely brown and dry, it is best to remove them before disease takes over the rest of the plant.
Strong sun and heat cause the breakdown of chlorophyll in the leaf. Damage appears as pale, bleached or faded areas. These areas eventually become brown and brittle. Symptoms are more severe when the strong sun is combined with dry soil conditions.
Scorch symptoms may differ between plant species, but it typically appears in July and August as a yellowing between leaf veins and along leaf margins, and a browning on the tips of leaves. Since these leaf parts are the last to be supplied with water from the roots, they are usually the first to be affected.
You will want to trim the dead or scorched foliage after properly watering. Your plant is expending energy on attempting to keep the burnt parts alive. Clip these areas off so that the energy it produces will go to the areas of the plant that are still healthy.
Occasionally, leaf scorch is caused by a bacterial disease that can result in permanent damage or death to your tree.
It can take anywhere from a couple of days to a couple of months for stressed plants to recover. Recovery time depends on the amount of damage that the heat caused to the plant. If a stressed plant is completely neglected during a heatwave, it can take several months or even be impossible to revive it.
As sad as it is, brown tips are dead tips. You can't revive dead leaf cells, but you can make corrections and save the rest of your plant.
The plant's appearance will perk up when new growth begins, and once new leaves have emerged, you could gently remove the scorched leaves if they have not already fallen off naturally.
Pigment changes, such as colored spots or patches (melasma), freckles, liver spots (solar lentigines) and age spots. White spots on your arms, legs and back of your hands (called idiopathic guttate hypomelanosis). Uneven skin color or uneven skin texture. Thinning of your skin.
Sunscald commonly discolors bark reddish brown, usually on the south and west sides of the trunk and limbs and on the upper side of poorly shaded horizontal branches. Bark then separates from wood, shrinks, appears sunken, and cracks and peels off in patches, exposing wood.
What can you do? Once leaf scorch has occurred, there is no cure. The leaves that have already turned brown will not recover, BUT as long as you water properly, the rest of the plant should survive. Deep watering is recommended – a slow, deep soaking of the soil at the roots.
If a plant is overwatered, it will likely develop yellow or brown limp, droopy leaves as opposed to dry, crispy leaves (which are a sign of too little water). Wilting leaves combined with wet soil usually mean that root rot has set in and the roots can no longer absorb water.
Sun sensitive plants need immediate shade after overexposure to the sun. If the plants are potted, then move them to a covered porch or indoors. If the plants are in the ground, then cover them with a fabric sun screen that is rated for landscaping. Watch the plants over the next few days to see how well they respond.
Sunscald injury of plants is easy to prevent, though there is no cure. Once leaves are damaged, all you can do is support the plant until it manages to grow new, stronger leaves.
Symptoms of excess sunlight on indoor plants
Strong sun and heat cause the breakdown of chlorophyll in the leaf. Damage appears as pale, bleached or faded areas. These areas eventually become brown and brittle. Symptoms are more severe when strong sun is combined with dry soil conditions.
Once the damage has happened, it's OK to remove the affected leaves, which should mostly be on the outside of the plant. Or, you can let them fall off naturally (they may be protecting leaves on the inside of the plant!) Make sure you are not watering too much or too little-do the finger test.
