Pests and diseases

Common problems and what to do.

The most common problems in Central Europe. Protection is listed from the gentlest option.

High riskMedium riskLow riskRisk for this plant according to the source · no label = no documented level
Glasshouse whitefly

Glasshouse whitefly

Trialeurodes vaporariorum
High riskpest
More about this problem

What you will see

Sticky honeydew on leaves, black sooty mould and tiny white winged insects.

The source says: it is among the crops highly susceptible to whiteflies.

When to look

Outdoors mainly in warm summers, under glass throughout the growing season

How to protect

  1. Prevention
    • Inspect new plants and, if possible, quarantine them.
    • Get rid of unneeded plants from the greenhouse so the whitefly has fewer hosts.
  2. By hand throughout the growing seasonYellow sticky traps are for monitoring, not a major control measure.
  3. Biological early, before a heavy infestationParasitic wasps (from a biological control supplier) attack whitefly larvae; release them early, before plants are heavily infested. Parasitised larvae turn black.

Blossom end rot

Blossom end rot

High riskphysiological disorder
More about this problem

What you will see

A dark sunken rot forms at the end of the fruit (the side opposite the stalk); it is caused by a lack of calcium in the fruit when water is uneven.

The source says: large-fruited vegetables like this one are particularly susceptible.

When to look

Summer

How to protect

  1. Prevention
    • Never let the plant dry out; in hot weather water even 2× a day, preferably twice a little rather than once a lot.
    • For a grow bag or pot, consider a larger container, automatic watering or mulch.
    • Extra calcium in the soil helps only a little: calcium reaches the fruit only when water flows evenly.

What you will see

Colonies of tiny insects on young shoots and under leaves, stunted and distorted growth, sticky honeydew and black sooty mould on it.

When to look

Spring and summer

How to protect

  1. Prevention
    • Tolerate a small number: aphids are food for beneficial insects.
    • Check plants often so you can act in time.
    • Encourage ladybirds, hoverflies, lacewings and parasitic wasps.
  2. By hand as soon as you spot themSquash colonies with your fingers or remove affected shoot tips.
  3. Biological before a heavy infestationIn a greenhouse you can buy in hoverfly larvae, lacewings and parasitic wasps.
  4. Chemical — only when nothing else helps according to the product labelLast resort only: a product authorised in your country against aphids. Try non-chemical methods first.

What you will see

Speckled leaves and early leaf drop.

When to look

Outdoors in summer, especially in hot, dry weather; under glass March to October

How to protect

  1. Prevention
    • Plants in a hot, dry, overcrowded greenhouse suffer more: increase humidity and airflow.
    • In autumn, remove heavily infested plants and clear away debris, canes and ties; disinfect the greenhouse thoroughly.
    • Weed around the greenhouse; weeds are hosts.
  2. Biological March to OctoberPredatory mites (from a biological control supplier) are the most common biological control against spider mites.
