How many years does it take for hemp walnut to bear fruit?

The results of hemp walnut planting for several years

After the hemp walnut seedlings are planted, they will bear fruit in 6-7 years if they are carefully cared for. Ornamental walnuts generally do not use seedlings because of their long growth cycle and the fruits they produce are not necessarily better than grafted ones, but the genes have not changed.

Grafted walnut blossoms and bears fruit

Grafted walnuts generally take 3 years to bear fruit, and enter the high-yield period in 4-5 years. During the maintenance period, water, fertilizer, temperature and light management need to be done well.

Potted walnut fruiting

If you are caring for the walnut in a potted plant, the number must not be large. Let it grow and bear fruit naturally as a landscape tree. If you must pollinate it, you can pick off the male flowers that are about to shed pollen when the male flowers bloom, dry them in the shade for 2-3 days, shake off the pollen, collect them and refrigerate them, and then take them out for pollination when the female flowers bloom and let them bear fruit in one year.

Why don't walnuts bear fruit?

The main reason why walnut trees do not bear fruit is insufficient pollination. It is a monoecious plant with a short effective pollination distance and a low self-pollination fruit set rate, making it difficult to bear fruit. Generally, artificially cultivated walnut trees need to be paired with pollination trees.

Key points for planting hemp walnut

1. Walnuts like an environment with plenty of sunlight, especially after entering the fruiting period, they need more sufficient light. However, if the light intensity is very high, shade measures need to be taken. The tree shape generally adopts two types: natural open heart shape and sparse layered shape.

2. The roots of hemp walnut are deep and the leaves are lush, so it requires a lot of fertilizer and water. It can be deep plowed once a year after the leaves fall, and combined with the application of basal fertilizer. Weeds need to be removed during the growth period, and topdressing should be done 2 to 3 times before germination, after the flowers fall, and during the hard-core period. Nitrogen fertilizer is mainly applied in the early stage, and the three elements of nitrogen, phosphorus and potassium cooperate with each other in the later stage to promote flower bud differentiation and improve kernel quality.
