Among the exotic species, kiwi is easy to care for and robust. Keeping them in the tub can only be made more difficult because the kiwi plants are very vigorous. You can reach heights of up to 10 meters in optimally chosen locations. Therefore, when buying, choose not only a variety that is sufficiently hardy for your region, but also a slow-growing variety.

Location and care of the bucket kiwi
Since you need at least one female and one male plant to harvest the fruits, a large planter - sufficient for two plants - or two adjacent tubs is required. The self-fertilizing kiwi varieties also bear better if you plant more than one plant next to each other.
A good substrate with a pH value in the acidic range is particularly important for the kiwi plants in the tub. Otherwise, the same applies to the kiwi in the bucket as to the outdoor plant:
- a sheltered, warm location is ideal,
- a stable climbing aid is required,
- do not fertilize young plants at all, fertilize older plants sparingly,
- water a lot in midsummer,
- a good drainage layer is required to avoid waterlogging,
- a layer of mulch maintains moisture and pH.
Cut of the bucket kiwi
In order to keep the kiwi bush, which is prone to overgrowth, in the bucket permanently, it is advisable to shorten the strong-growing branches consistently, several times a year if necessary. Only in the early spring before flowering should not be cut, as there is a risk that the flower buds attached to the biennial wood will be cut away. During the summer, the fruit shoots are first cut five eyes behind the fruit, and then one or two eyes behind with a second cut.
Tips & Tricks
The bucket kiwifruit should be wintered in the first year frost-free and dark. Later, good winter protection must be provided around the bucket and in the root area. The mini kiwifruit need additional protection against late frosts in spring during sprouting.
