8 Reasons why tomato leaves get brown edges<\/h2>\n\n\n\n

Here are the top reasons why tomato leaves can get brown edges and how to solve each one.<\/p>\n\n\n\n

1. Old leaves<\/h3>\n\n\n\n

The old leaves on tomatoes will eventually turn brown starting on the edges and spreading to the whole leaf. This will start near the base of the stem. This is a natural process and won\u2019t harm the plant. These leaves can be pinched off or cut back with sharp secateurs.<\/p>\n\n\n\n

Cut them close to the main stem but make sure you don\u2019t damage it. This can allow an entry point for pests or diseases.<\/p>\n\n\n\n

2. Insect attack<\/h3>\n\n\n\n

Insects can attack tomato leaves particularly new growth causing holes and brown and yellow<\/a> edges. Aphids and spidermite are common pests that can suck the sap from the leaves. They can quickly multiple when the weather starts to warm up.<\/p>\n\n\n\n

Spray the leaves with neem oil to get rid of these sap sucking insects. They won\u2019t harm the beneficial insects or the plant. It can be applied 2-3 times until the pests are under control.<\/p>\n\n\n\n

Chewing bugs such as caterpillars, snails and slugs can eat holes in tomato leaves causing them to turn brown<\/a> on the edges.<\/p>\n\n\n\n
