Grow chinese cabbage in field farming. The chinese cabbage (napa cabbage) that we started cultivating in early August is now ready for harvest.
Chinese cabbage cultivation (Napa cabbage days to maturity)
Chinese cabbage (Napa cabbage) underwent soil preparation in early August. We use fully ripened cattle manure compost, chicken manure, and canola cake as fertilizers. Since we are growing chinese cabbage through organic farming, we also use organic fertilizers.
The planting time for chinese cabbage seedlings was early September. The required spacing between napa cabbage plants is about 40cm (15.7 inches). If there is enough space, a spacing of 50-60cm (1.6-2.0 feet) would also be suitable.
Chinese cabbage, winter cabbage, and other heading vegetables may not form tight heads if the planting of seedlings is delayed. Therefore, let’s make sure to plant them at the appropriate time. For autumn planting, early to mid-September is a suitable time for planting chinese cabbage seedlings.
The Brassica family, including chinese cabbage, is prone to pests such as aphids and cabbage worms if preventive measures are not taken at the time of planting. After planting the chinese cabbage seedlings and watering, immediately set up insect netting and cultivate them under grow tunnel.
The chinese cabbage planted is growing well after transplantation. About 3 weeks after planting the seedlings, at the end of September, we fertilized the chinese cabbage.
Vegetables like chinese cabbage and green cabbage, grown from seedlings, require additional fertilization about 3 to 4 weeks after planting. The fertilizer used for additional fertilization is organic chicken manure. The amount of fertilizer applied per location is 20cc (3/4 oz) of chicken manure.
Concerning pests, setting up insect netting and cultivating under grow tunnel can provide some protection, but it’s also important not to neglect visual checks. If you see holes in the chinese cabbage leaves or insect droppings, there is a very high likelihood that there are pests present. (Dispose of the found pests immediately.)
Chinese cabbage harvest time (Best time to harvest napa cabbage)
The indicator for determining the harvest time of chinese cabbage is the firmness of the head. When you’re wondering if it’s time to harvest, try pressing the chinese cabbage head from the top. If you feel a firm resistance, it’s time to harvest.
The harvesting method for chinese cabbage is by the whole plant. To harvest chinese cabbage, cut the heads off the root system with a sharp knife.
The harvested chinese cabbage had a diameter of about 12cm (4.7 in.) and a length of about 25cm (9.8 in.). This year, with many warm days and favorable weather, it seems that the chinese cabbage grew quickly.
I still have one chinese cabbage plant remaining, so I’d like to harvest it again around the time we finish eating the portion we harvested this time.
