Where to Plant Onions in Spring: List of the Best Predecessor Vegetables
Not a single gardening season goes by without planting onions. Even if the vegetable does not grow, is sick, and the harvest is poorly stored, the gardener tries to understand the reason and persistently goes about his business.
We will tell you after which crops it makes sense to plant onions in the spring, so that there is something to collect for storage at the end of the season.
There are crop rotation rules that are more expensive to cancel and ignore. Not only will you fail to grow any successful harvest, but you can also ruin the fertile soil layer on your plot.
Do not plant the vegetable where any of its onion relatives grew – onions, shallots or leeks, as well as garlic.
Neglect of this rule can result in soil depletion, development of fungus and pest larvae.
Onions will yield a good harvest if they grow after legumes, nightshades, pumpkin crops, as well as umbelliferous and cruciferous plants.
You should also follow the advice on selecting seeds and storing them:
- the size of the onion set is 3-4 cm in diameter, and large sets will produce good greens;
- seeds should be stored in a warm room with an air temperature of no more than 20 degrees Celsius;
- About a month before planting, the sets should be left in a warm place for 12 hours, for example under a heating device, and then returned to the previous conditions for 2 weeks;
- 10-12 hours before planting, the sets should be kept in warm water.
