How to grow calla lilies well

1. Maintenance methods

1. Temperature: The range of 20 to 25 degrees is relatively suitable. It is not good to be too high or too low. In summer, it should not be too hot or too humid, and the humidity should not be too high. In winter, the most suitable temperature for hibernation is between ten and fifteen degrees.

2. Light: The suitable environment for calla lilies is semi-shade, which means it cannot be too dark, nor can the sunlight be too strong. Therefore, it can be adjusted according to the specific sunlight intensity, and shade can be provided when it is too strong. However, during the growth period, try not to keep it too dark, otherwise it will affect its growth.

3. Watering: Calla lily likes moisture, but not too wet, because it is also afraid of waterlogging. Generally speaking, the substrate can be in a semi-wet state, but no water should accumulate. If it rains very heavily, the accumulated water must be drained out in time.

4. Fertilization: Calla lilies do not require much fertilizer, so just add some base fertilizer to the soil. In addition, top dressing can be applied only slightly during the flowering period.

2. Breeding techniques

1. Reproduction: Sowing is a common method, and both “row sowing” and “spot sowing” are possible. When sowing, the seeds need to be sprinkled evenly one by one, and then covered with a layer of fine soil. Then use tools such as a watering can to add moisture, and equip it with a sunshade net. The sunshade net can be opened for a while in the morning and evening to make it more breathable, but it must not be opened at noon.

2. Pruning: Usually, pruning is mainly aimed at its leaves, such as aging, dry and yellow leaves. In addition, pruning is also an important step once diseases, pests and infestations occur.

3. Problem diagnosis and treatment

1. Diseases: Common diseases include "soft rot", which occurs in the roots and stems and can be treated with streptomycin. There is also "white rot", which can cause serious damage to the leaves. It can be sprayed with carbendazim, usually once every ten days, and needs to be sprayed two or three times in a row.

2. Pests: The most common and most harmful one is the scale insect, which can also spread some diseases, so it is very harmful. It can be sprayed with omethoate solution.
