For calla, the success rate of sowing method is relatively high, and choosing the right time can improve the survival rate. It's better in March or August. However, if the temperature is suitable, it is generally OK in spring or autumn.
1. Selection of matrix: appropriate matrix is also helpful for survival. Perlite can be used to add coarse sand, rotten leaf soil, peat soil and so on. No matter what kind of substrate, it should be disinfected before use. It can be exposed to the sun for several days, or other disinfectants can be used. Its root is weak, if there are bacteria, it may cause a greater impact.
2. Seed selection: its seed setting rate is not very high, so we can choose a robust mother plant artificially, and then pollinate it. Then collect the seeds
After the seeds are collected and the substrate is prepared, the seeds can be sown. Choose the plump seeds and sprinkle them into the soil as evenly as possible. Then, cover with a layer of soil
It's going to be 20 degrees up and down all the time. Pay special attention to the light. If the light is strong when sowing, remember to shade after sowing, for example, with the help of sunscreen. About a month or so, the seeds will germinate and grow seedlings. Under the normal maintenance, the next year you can raise flowers.
