Antirrhinum majus likes a relatively cool climate, and is especially afraid of intense heat. It is relatively cold-resistant. In winter, the maintenance temperature is guaranteed to be above 0 . In summer, the antirrhinum majus can safely live through the winter and spend the summer by pulling a sunshade net to block the light and cool down.

During the growth period of snapdragon, liquid fertilizer, such as compound fertilizer and water, can be applied once every half a month to promote growth, and phosphorus and potassium fertilizers, such as potassium dihydrogen phosphate, can be used before the flowering period to promote flowering.When applying fertilizer, we should pay attention to thin fertilizer and frequent application, and the concentration is lighter and safer.
In the seedling stage of Antirrhinum majus, pinching can be carried out to promote more branches of the plant, that is, when the seedling grows to 6 leaves, the top 2 leaves are removed and 4 leaves are retained.In addition, 15cm stems should be retained after each flower failure, and the residual flowers and top branches and leaves should be cut off to promote the plant to grow new branches and blossom again.
