Ilex crenata, the Japanese holly, is a very frugal plant that has proven itself as a hedge plant. It needs few nutrients. Therefore, frequent fertilizing is not necessary. What do you have to consider when fertilizing Ilex crenata?

The Japanese holly must not be fertilized too much

When do you need to fertilize Ilex crenata?

If you prepare the soil or the substrate in the pot properly before planting, you won't have to fertilize at all in the first few years.

The plant loves a lime-free, slightly humus-rich soil. Enrich it with mature compost and horn shavings (€32.93).

If you don't want to do without fertilizing, for example because the holly seems a bit stunted, work in some compost in the spring.

The right fertilizer for the Japanese holly

Chemical fertilizers are not necessary. If necessary, you can administer a long-term fertilizer in the spring, but only in half the dose.

Mature compost, which you work lightly into the soil in spring, is more suitable as fertilizer. Horn shavings are also a good fertilizer for Ilex crenata.

Never over-fertilize!

Ilex crenata is sensitive to too high a nutrient content in the soil. Therefore, avoid over-fertilizing the plants.

Never fertilize on very hot summer days. The last application of fertilizer should take place at the end of July. Otherwise, the new shoots can no longer mature properly before winter.

Apply mulch layer

The best thing you can do for your Ilex crenata is to apply a layer of mulch in spring. It has many advantages:

  • Loosen the soil
  • prevents water from evaporating
  • releases nutrients
  • protects against frost in winter
  • prevents weeds from emerging

The water balance of the soil is well regulated by the mulch material. As the material decomposes, it releases nutrients that seep into the soil. This avoids over-fertilization.

The mulch layer also protects the Ilex crenata from frost damage in winter and prevents weeds from spreading under the shrub.

Suitable mulch materials are:

  • healthy foliage
  • chopped lawn clippings (without seeds)
  • straw
  • shredded garden waste

tips

Ilex crenata can be self-propagated if you are patient. The easiest way to propagate is to use sinkers. But you can also cut cuttings in summer.
