Pests

Pests are animals – mostly small insects or mites – that infest and damage plants. In cultivation, they can cause a lot of trouble because they multiply quickly and rapidly weaken a healthy plant. Those who recognize what is happening early can usually counteract before greater damage occurs.

Common Pests

Among the best known are spider mites: tiny animals on the underside of leaves, recognizable by fine webs and light speckles on the leaves. Fungus gnats are small black flies whose larvae live in moist substrate and disturb the roots. Aphids sit in colonies on shoots and suck plant sap, while thrips leave silvery, punctured marks on the leaves. Common to all: the earlier you notice them, the easier it is to combat them.

Prevention and Detection

The best prevention is a healthy environment. Good ventilation, avoiding waterlogging in the substrate, and regular checks – especially on the underside of leaves – keep many problems small. In indoor cultivation, a clean grow box helps to make infestation more difficult. A look with a magnifying glass is worthwhile: many pests are barely visible to the naked eye. If they are detected early, countermeasures remain manageable.

Frequently Asked Questions about Pests

Which pest is most feared?

Spider mites are considered particularly stubborn because they are tiny, multiply quickly, and are often only noticed late.

How do I detect an infestation early?

By regularly checking the undersides of leaves – preferably with a magnifying glass – and looking for speckles, webs, or sticky traces.

How do I prevent pests?

With good ventilation, no waterlogging, a clean environment, and regular checks. A healthy climate is the best protection.
