Sowing time

Because fragrant snowballs are afraid of heat during the growth period, and the most suitable temperature for sowing is 15 ℃ - 20 ℃, autumn sowing is generally carried out after the middle and late September

Sowing preparation

The substrate can be nutrient soil, river sand, peat soil, etc. the substrate should be disinfected before sowing. The best way is to put it into the pot and fry it at high temperature to inhibit the production of diseases and pests

The seeds should be soaked in warm water for 12-24 hours until they absorb water and expand

Seeding steps

For small seeds that are difficult to pick up by hand or other tools, wet one end of the toothpick with water, put the seeds on the surface of the substrate one by one, then cover the substrate, about 1cm thick, press it slightly, and then put the seeded flowerpot into the water. The depth of the water is 1 / 2-2 / 3 of the height of the flowerpot, and let the water soak up slowly

The proper temperature for the germination of snowball is 20 ℃. Generally, the seedlings emerge in 5-10 days, and can be planted in pots when there are 3-4 real leaves

Post sowing management

After sowing in autumn, if you encounter cold wave and low temperature, you can wrap the flowerpot with plastic film, which is conducive to heat preservation and moisture retention

After the seedlings are unearthed, the film should be uncovered in time, and the seedlings should be exposed to the sun before 9:30 a.m. or after 3:30 p.m. every day, otherwise the seedlings will grow very weak

After most seeds are ready, appropriate thinning is needed, and the diseased and unhealthy seedlings should be pulled out, so that there is a certain space between the remaining seedlings

When most of the seedlings grow three or more leaves, they can be transplanted into pots
