How to Grow Kochia: Seed Propagation Tips and Precautions

In front of the gates of farmhouse courtyards, there are often one or two lush green kochia plants, especially verdant, adding a touch of green to the surrounding scenery. The lush green kochia always brings people a feeling of freshness and tranquility; that little big round ball is quite the adorable thing, so how do you grow kochia? How do you sow and propagate it? What precautions are there?

I. Cultivation Methods for Kochia

1. Soil

Kochia does not have high soil requirements. It prefers loose, fertile, humus-rich, well-drained sandy soil, but it can also tolerate poor and thin soil, and can also tolerate alkaline soil.

2. Light and Temperature

Kochia likes a sunny, well-lit environment, but it is also a relatively shade-tolerant plant.

In terms of temperature, kochia likes warmth and is not cold-tolerant. In addition, the suitable temperature for kochia germination is between 10-20°C.

3. Water and Fertilizer Management

In terms of water and fertilizer management, the care and management of kochia is still very simple and extensive. Basically, when planting out, you need to first apply a sufficient amount of base fertilizer to the kochia and water it thoroughly once,

After planting out, kochia needs to be given additional fertilizer 2-3 times per year, though of course it can also be left unfertilized. As for watering, although kochia can tolerate drought, you should still supplement a certain amount of water to keep the soil moist, so that kochia will grow well. During the growing season, water once every 7-10 days. Let the soil dry and then get wet again, and avoid waterlogging.

4. Propagation Methods

Kochia is generally propagated by sowing seeds, usually done in spring by direct sowing. Sow kochia seeds in April each year; before sowing, apply base fertilizer and keep the soil moist. Seedlings will emerge in about 10 days, and then you can plant them out at the appropriate time. Kochia seed propagation germinates quickly and uniformly, and is simple to care for.

II. Seed Propagation Methods for Kochia

1. Collecting Kochia Seeds

Kochia has a certain ability to self-sow, but it can also be sown manually. In August and September, when kochia blooms and sets fruit, and the fruits are ripe, you can collect the seeds. Remove the fruits from the kochia, get rid of impurities, and let the fruits dry in the sun for later use.

2. Timing for Kochia Seed Propagation

If kochia seed propagation is done by direct sowing, it can be done in early April. If kochia is sown in a nursery bed, sowing can be done from early to mid-March, and the seedlings can be transplanted once they have grown.

3. Direct Sowing Propagation of Kochia

When propagating kochia by direct sowing, you can choose a suitable sowing site, either outdoors or in a flower pot.

If sowing outdoors, you need to choose a spot with plenty of sunlight, good ventilation, and good drainage. Prepare a suitable seedbed, add some decomposed fertilizer to the soil as base fertilizer to provide kochia with sufficient nutrients. Water the prepared seedbed thoroughly once, mix the seeds with fine sand, and scatter them on the seedbed, making sure to keep a suitable spacing between plants. Cover the seeds with a layer of soil, with a thickness such that the seeds are no longer visible. If conditions allow, you can spread a layer of straw over the soil to keep it moist. With straw covering it, when watering you can pour the water onto the straw to avoid washing the seeds away. Once the seeds germinate, the straw can be removed. When propagating by sowing in flower pots, the method is actually about the same, but note that flower pots have limited space, so you need to reduce the number of seeds.

4. Raising Kochia Seedlings by Sowing

Raising seedlings by sowing is actually also very simple; you just need to transplant and plant out the kochia seedlings when they grow true leaves.

III. Precautions for Growing Kochia

1. Kochia Pests and Their Control

During the growth process, kochia is not very prone to diseases, but it does still have pests. Kochia is susceptible to aphid damage. When aphids are found, you can remove them by hand or use biological control methods. In addition, you can also spray a 1000-1200 times dilution of 40% dimethoate emulsifiable concentrate to repel the pests, or spray a 500 times dilution of 10% imidacloprid wettable powder for control.

Besides aphids, there is also damage from green caterpillars, which mostly occurs from late June to mid-August. When green caterpillar damage is found, you can remove the insects by hand or use pesticides, spraying a 1000-2000 times dilution of 40% dimethoate emulsion or a 4000 times dilution of 20% Dingkang granules for control.

2. Weed Control for Kochia

Kochia is easily parasitized by dodder (Cuscuta) and will also grow many other weeds. When you find that kochia has been infested by dodder or other weeds, you should promptly remove and manage them. Weed removal can mainly be done using manual control, mechanical control, chemical control, ecological control, and other methods.

Manual control mainly has two aspects. Before sowing, carefully check whether weed seeds or the like are mixed in with the seeds, and screen them out. Second, when weeds are found, pull them out by hand directly; of course, the whole process will be somewhat laborious.

Chemical control is actually just applying pesticides, using pesticides to remove weeds growing rampantly. There are currently many herbicides on the market that can be used to spray and remove weeds for kochia. This is relatively fast and saves time and effort, but you need to prevent weeds from growing back, as well as cases of pesticide poisoning.
