Support long shoots
Caring for Japanese grapes is made much easier with the right form of cultivation. The long, flexible rods cannot stand upright on their own and therefore bend to the ground in an arch. Draw the Japanese grape berries as a trellis or tie their shoots to a stake or similar. Ä.

Cutting that has been removed
That Cut is an important maintenance measure that must be carried out every year. Because all rods that have once borne fruit will no longer bear fruit in the following years. Rather, they will die off after the harvest.
You have to cut these worn rods close to the ground in autumn after the harvest. In rough locations, however, you should wait until spring to do so.
Remove the weakest specimens from the young shoots in autumn so that max. 10 shoots per meter remain. In spring, shorten the remaining rods to 2-3 m and the side shoots to 10 cm.
Quench your thirst
The Japanese grapeberry is considered thirsty. It demands more than nature can give it in the form of rain and soil moisture. Therefore it has to be watered additionally.
- Water depending on the weather
- twice a day on hot days
- in the morning and in the evening
- never in the blazing midday heat
- reduce watering in winter
Tips
Mulching Cover the root area with leaves so that less soil moisture evaporates on hot days.
Fertilize for a good harvest
Promote grape berry growth with nutrients it craves. These are especially phosphate and potassium. Nitrogen ensures a stronger shoot growth. But it doesn't bring more flowers. This is what the ideal fertilization looks like:
- first fertilization takes place in spring
- with a fertilizer containing potassium and phosphate
- The second fertilization follows in autumn
- this time with some garden compost
Overwinter
Young plants that they bought fresh or from aslice or sinker multiply, need winter protection. Likewise specimens that grow in the bucket. Cover them with sticks before the first frost. You can also wrap a bucket with warming fleece.
