Can walnuts bought for eating be used as seeds for planting?

Walnuts are a common nut in our country and are widely cultivated because of their high nutritional value. They are now grown in most regions. So can walnuts bought for eating be used as seeds for planting?

1. Can walnuts bought for eating be used as seeds for planting?

Naturally air-dried walnuts grown at home can be used as seeds for planting, but if they are oven-dried walnuts, then they cannot be planted, because after being exposed to high temperatures, oven-dried walnuts have lost the possibility of sprouting. In spring, naturally air-dried walnuts can first be cracked open a little, then placed in water to soak and sprout. Once the shell splits open and sprouts and roots emerge, they can be taken out and planted in the soil. Generally, unn grafted ones can bear fruit in 5-7 years.

2. How many years does it take for planted walnuts to bear fruit?

If a walnut tree is a seedling tree, that is, one grown directly from seed without grafting, this kind of seedling generally needs 7-8 years of growth before it bears fruit; if it has already been grafted, then it should be a late-fruiting variety, and the fruiting period depends on the level of cultivation management, generally 5-6 years. If it is confirmed that it has not been grafted, then in spring it can be top-grafted and changed to an excellent variety, and it can bear fruit in the 2nd year after grafting. It is worth mentioning that pruning walnut trees is a measure that can effectively increase yield and the fruiting period.

Overall, naturally air-dried walnuts can be used as seeds for planting, but if they are oven-dried walnuts, then they cannot be planted, because high temperatures cause the seeds to lose their ability to sprout.
