Ilex crenata Dark Green is an all-male Japanese holly variety. It only flowers, but produces no fruit. This makes it the ideal hedge plant for gardens with children. As with all Ilex crenata varieties, disease is very rare with Dark Green.

The Ilex crenata Dark Green is very robust

What diseases does Ilex crenata Dark Green have?

There aren't many diseases that bother the Ilex crenata Dark Green. If they occur, it is usually due to a bad location or too few or too many nutrients in the soil.

In the first place, these problems can damage the Ilex crenata Dark Green:

  • fungus
  • chlorosis
  • pest infestation

Basically, it can be said that the robust, evergreen shrub can cope well with diseases and pests if it is strong and in a favorable location.

Soil fungi damage the Ilex crenata Dark Green

Soil fungi appear when the site is generally too damp. Therefore, make sure that there is never waterlogging. However, the holly must not be completely dry.

If the plant smells foul, look at the roots. Dead root ends and a whitish coating are signs of fungal infestation.

Watch out for pests

Especially in very dry locations, pest infestation by spider mites can occur. It can be recognized by the spots on the leaves. If the young leaves also take care and fall off, look at the undersides.

Control should be carried out by biological means such as ladybugs, lacewings and assassin bugs.

Chlorosis bleaches the leaves

If the leaves fade, become almost transparent and fall off, chlorosis is probably responsible. In this case, the Ilex is too dark or the pH of the soil is too high.

Yellow leaves when waterlogged

Ilex crenata Dark Green does not tolerate waterlogging at all. He reacts to this with many leaves turning yellow.

tips

Like all varieties of Japanese holly, Ilex crenata Dark Green is very easy to care for. You should only give the Ilex some winter protection, especially if you have just planted it.
