The slightly poisonous Aralia catches the eye with its pinnate leaves. It is known as a dense, large shrub for outdoor planting and is also known under the synonym Japanese Aralia.

What must be considered in relation to casting?
Once planted and properly rooted, this Aralia does not need constant watering. It is recommended to cover the soil with a layer of mulch. So the soil doesn't dry out too quickly. At best, the environment is kept moist.
How often should you fertilize the aralia?
Fertilize this plant with a dose of compost in the spring. If there is no compost, you can also use another organic fertilizer. Fertilizers such as nettle manure and horn meal are also good. Only if the nutrients in the soil are right will this Aralia flower.
Do you have to overwinter the Japanese Aralia?
It is not necessary to overwinter this plant. Due to its origin, it can also deal well with a Central European winter. It is hardy down to -25 °C. Nevertheless, it is advisable not to put this temperature minimum to the test.
Protect your Aralia if you only planted it in the fall. Recently propagated specimens should also be protected outdoors in winter. The following points must be observed for winter storage:
- Leave the leaves of the plant as protection
- alternatively apply a layer of compost or spread brushwood
- Be careful not to get wet in winter
- young shoots can freeze - cut them off in spring
How to properly prune this plant?
There is nothing special to consider when pruning. The only thing that is important to know is that the aralia does not branch much and should preferably be pruned in winter. In the course of pruning, you can keep individual shoots and use them to propagate. Japanese Aralia cuttings are easy to root.
tips
