How do you select arugula seeds?
Arugula generally blooms and bears fruit in late June, and at that time the seeds will also gradually mature. Friends who grow arugula can collect the seeds themselves and use them for sowing. When selecting seeds, choose seeds that are plump, disease-free, and free of appearance defects; it is best to select seeds more suitable for planting according to local conditions and climate.
What are the seedling raising methods?
1. Seedling raising conditions
Arugula does not have strict environmental requirements, has strong drought resistance and tolerance to barren soil, and can grow by roadsides or in the wild. The most suitable temperature for seed germination is 15°C-20°C. When the soil moisture content is suitable (relative moisture content between 70%-80%), stem and leaf growth is better. The entire growth period is 50-60 days.
2. Sowing and seedling raising
Generally sown in May, the seedlings emerge in early May. The sowing method can be direct sowing, drilling, or broadcasting. When sowing, mix 2-3 times the amount of fine soil with the seeds before sowing. After sowing, press lightly, cover with a thin layer of fine soil, and water thoroughly. In arid areas, after sowing it is best to cover the seedbed surface with a black shade net or other mulch to retain moisture.
3. Thinning and final singling of seedlings
When the arugula seedlings have grown about three leaves, they can be thinned and singled, and at the same time weeds in the field should be removed. After thinning, according to the growth of the arugula seedlings, appropriately add some nitrogen fertilizer. In addition, arugula likes water. During its growth period, the soil should remain moist. Except on rainy days, water should be sprayed on the arugula in all other weather conditions.
4. Transplanting management
After two weeks, the arugula will grow main leaves. At this time, temporary transplanting is needed, covering the leggy part with soil so that it looks sturdy. After transplanting, because the leaves will become larger, it needs to be moved into a large flowerpot containing base fertilizer and good soil.
5. Pest and disease control
Arugula generally rarely suffers from pests and diseases, but in hot and rainy summers, it is also prone to some leaf spot disease, and there will also be some small diamondback moths and the like, all of which can be controlled with relevant pesticides.
Overall, arugula grows very quickly. Generally, after planting, it can be harvested in about one month, which is very suitable for home pot cultivation. If harvesting the flowering stems, generally after final singling, they can be harvested in about 45 days. I wonder if you have ever grown it at home?
