After planting onions. Explains additional fertilizing and watering that beginners tend to fail.

In the case of onion (early) cultivation, after the seedlings are planted, neither fertilizer nor water is applied until additional fertilizer is applied in late December. You can leave the water to the weather. If it doesn't rain for two weeks, water lightly on the way. Fertilizer after planting seedlings will be 3 times in late December, late January, and late February. For additional fertilization in late December and late January, use chicken manure or organic compound feed that has a long fertilizing effect.
The point is additional fertilizer in late February. Early ripening will be harvested in early April. If you add a fertilizer with a long fertilizing effect in late February, it will not be in a state where it can be harvested even when it is harvested in April. By mid-March, the fertilizer should run out and the nutrients in the leaves and stems should return to the beads. Therefore, the fertilizer in late February is called stop fertilizer or fertilizer stop, which is the last fertilizer before harvesting and has a short fertilizer effect. Nutrients in the stems and leaves return to the balls, and the leaves wither and the stems soften and break. This is a sign that the onions are delicious. Be careful not to over-fertilize or water.
