What are the seedling raising methods?
Viola cornuta seeds are very small, so generally a 200-cell or 288-cell tray is chosen for sowing. The sowing medium is generally imported seedling peat moss or sterilized domestic seedling peat moss, with a PH value of 5.5-6.2. After sowing, a thin layer of vermiculite is needed to cover the seeds to retain moisture. If the substrate is too dry, it may lead to uneven germination. The germination temperature should be kept at around 20°C.
Stage one: within 3 to 4 days the radicle appears and rooting begins
Control the temperature at 20°C-21°C. Germination does not require light, but giving 50-200 lux of light can promote germination.
Stage two: germination is complete, and stems appear and the cotyledons unfold
The focus at this stage is to let the substrate dry slightly to help the roots penetrate the substrate. Control the daytime temperature at around 20°C and the nighttime temperature at around 18°C. Apply a nitrogen-containing fertilizer at 4000 times dilution or a calcium-containing fertilizer. In addition, Viola cornuta does not need supplemental lighting at night, otherwise it will cause premature flowering.
Stage three: the roots penetrate into the cells of the tray
When the first true leaf appears, keep the temperature control and fertilizer application rate the same as in stage two, and control light at between 25,000-30,000 lux.
Stage four: the root system can easily hold the tray substrate in place, forming a root ball
When there are two or three pairs of true leaves, maintain appropriate humidity and avoid leggy seedlings. To make it flower earlier, lower the nighttime temperature to 15°C. The fertilizer usage is the same as in stage three, and control light at between 30,000-35,000 lux.
The above is an introduction to the varieties and seedling raising methods of Viola cornuta seeds. Overall, sowing Viola cornuta seeds is not difficult; the key lies in raising the seedlings. Check the seedling status regularly and do a good job of seedling management, and basically you can make it bloom in a full pot.
