The Ilex crenata is only partially hardy
Ilex crenata is only partially winter hardy
In contrast to the native Ilex, the Japanese holly, Ilex crenata, is only partially hardy. This is especially true for still young plants. How to bring the decorative hedge plant well over the winter.
How hardy is Ilex crenata?
Although Ilex crenata basically copes with low temperatures. However, this only applies to older plants that have been in the same place for some time. They have a well-developed root system and the shoots are mature, so they do not mind the cold so much.
Younger Ilex crenata needs protection from frost.
Ilex crenata overwinter in the field
When planting, make sure that there is not too draft, as too much drafts add too much to the Ilex, especially in winter.
Put a mulch cover under the plants. You can use grass clippings, bark mulch, leaves and other garden remnants. The mulch cover not only protects against frost, but also prevents the soil from drying out too much.
You can also protect young plants with garden fleece or brushwood from frost.
Do not fertilize Ilex crenata too late
Actually, you do not have to fertilize the Japanese holly. If you do not want to do without fertilizer, you should give extra nutrients until the end of July at the latest.
Fertilize later, the new shoots can not harden properly and freeze in frosty temperatures.
So overwinter Japanese holly in the tub
If you maintain Ilex crenata in the bucket, you should always provide winter protection. In the pot, the earth freezes much faster than in the field.
If you need to overwinter the plants outside, place the bucket on a dampened surface. Choose a place where there is little draft and where it is sufficiently bright. The location should not be too humid either.
Well suited for wintering are bright basements, garages or attics.
Tips
Although Ilex crenata does not like waterlogging, it does not tolerate complete dryness. Especially in very dry winters you should water the Japanese holly on frost-free days, so that it does not dry up.
