What signs indicate that seedlings have been burnt under supplementary lighting: tips for treating plants

A common problem faced by gardeners who grow seedlings is that plants are damaged by phytolamps. Burns can also appear due to sunlight.

As the expert of the online publication BelNovosti, agronomist and landscape designer Anastasia Kovrizhnykh explained, eggplants are most susceptible to such “injuries”, and sweet peppers and tomatoes are less susceptible.

If we talk about the last two crops – peppers and tomatoes – burns often appear after the seedlings “move” to open ground or a greenhouse, without waiting for the moment when the plants are hardened by sunlight.

Signs of damage from a phytolamp or the sun

Below you will find signs that will help you avoid confusing burns with damage left by pests.

Injuries from a phytolamp or the sun are flat, and the damage does not affect the back (lower) side of the leaf.

Typically, damage affects the highest points on the plant – the upper leaves.

How to cure damaged plants

To help plants recover from burns, you need to water them not from above, but at the roots or through a tray.

You should also increase the distance between the plants and the phytolamps. If the plants are on a very sunny windowsill, try to shade it to protect the seedlings from direct sunlight.

In addition, you should remove plants from the windowsill during the brightest sunny hours, which usually occur between 12 and 2 p.m.

Earlier we talked about growing tomatoes using Maslov’s method.
