The harvesting of Allium ochotense Prokh is highly seasonal, with a harvesting period of only about half a month. Generally, Allium ochotense Prokh can only be harvested after growing for six years. There are three methods of harvesting: whole plant harvesting, leaf picking harvesting, and ground cutting harvesting. Different harvesting methods are chosen depending on specific needs and environmental conditions of the planting area. Harvesting can take place in April and July, and both tender leaves and young shoots can be harvested for consumption.
1. When to Harvest Allium ochotense Prokh
Allium ochotense Prokh can only be harvested after it has grown for 5-6 years. There are three methods of harvesting. First, the whole plant harvesting method involves digging up the entire clump of plants. This method is typically used around the 5th year of growth. Second, the leaf-picking method involves picking around 2 leaves from each branch after the leaves have expanded, allowing for annual harvesting.
The third method involves cutting all above-ground parts after the leaves have expanded. After cutting, the plant will continue to grow new leaves, but these leaves will be smaller, thinner, and weaker. It will take about 2 years for the plant to recover to normal size, and the leaves will still remain small. Therefore, harvesting should be done every other year. Allium ochotense Prokh can be harvested for consumption during the spring and summer seasons each year.
2. How to Plant Allium ochotense Prokh
Allium ochotense Prokh is generally planted in late March during the spring. Before planting, select high-quality seeds and choose a sandy loam soil that has not been used to grow onions or garlic crops as the seedbed. The soil should be deeply tilled and finely raked, followed by the addition of well-decomposed organic fertilizer. Mix the seeds with fine soil evenly, then scatter the mixture over the seedbed and cover with 1.5 cm of soil. Use a plastic film to cover the seedbed to maintain warmth and moisture.
Two days before transplanting, water the seedbed thoroughly. Then, transplant the seedlings with a spacing of 4 cm between each plant, burying the bulbs in soil, leaving the onion hearts exposed. Finally, water and apply fertilizer.
