So how should it be grown? Below, the editor will bring you its planting methods. Let us learn about it together.
1. Site selection and land preparation
Choose loam or sandy loam planting land with deep soil layers and loose, fertile soil texture, plow 20-25 cm, and apply 2000-2500 kg of fully decomposed farmyard manure per mu as base fertilizer. Spread it evenly on the ground, rake it fine and level it, then make beds 50 cm wide and 15 cm high, rake the bed surface level, and leave 25-30 cm drainage ditches between beds to avoid waterlogging. It can also be planted on ridges.
2. Sowing
The sowing time for verbena is generally from late April to early May. Open furrows on the bed surface for drilling, with a row spacing of 25-30 cm and a furrow depth of 1.5-2 cm. Sow the seeds evenly into the furrows, but pay attention to the plant spacing to avoid it being too dense after emergence. Generally, 1 jin of seeds is used per mu. After sowing, cover with soil and press gently with your hand. After sowing, under suitable temperature and humidity conditions, seedlings generally emerge in 10-20 days. At this time, seedling-stage management should be done well.
3. Field management
When the seedlings grow to 5 cm, thin them in time, controlling the plant spacing at about 10 cm, so as to facilitate branching and give the seedlings sufficient growing space. After thinning, the excess seedlings can be transplanted elsewhere. After thinning, pay attention to the survival rate of transplanting, and replant missing seedlings in time. Verbena should often be weeded together with weed control to promote root growth. Weed frequently and keep the field free of weeds. Water in time during drought. During the rainy season, drain water and loosen the soil in time to avoid soil compaction and affect plant growth.
4. Pest and disease control
Verbena rarely has serious pests and diseases during planting. Generally, when there is standing water in the field, root rot occurs, so good water management is extremely important. Drain water and loosen the soil in time to avoid standing water in the field. To control root rot, spray carbendazim and drench the roots. When the condition is serious, spray once more after a week.
