The culture of Salvia can be transplanted when it grows to a certain extent, usually when the plant has 2-3 leaves. It should be noted that sage likes alkaline soil and calcareous soil is suitable, but common garden soil is also available. You can choose loose and permeable soil and mix some compound fertilizer as base fertilizer.
Sage likes warm growing environment. It needs enough light to grow well. Basically, sufficient light is needed for sage, but shade is needed in summer, and the light needs to be strengthened during the seedling period of sage to avoid excessive growth. It is necessary to keep a certain growth temperature during the growth of Salvia, not too high or too low. If the temperature is too low, the leaves of Salvia will turn yellow. If the temperature is too high, the flowers and leaves of Salvia will be small, and the plants will not grow well or even stop growing.
Sage likes a dry climate, but it can't be too dry. When the plants are short of water, they need to be watered in time. Of course, in rainy seasons, they need to be drained in time to avoid water accumulation. Fertilization should be reasonable, which is conducive to the growth of sage plants. During the growth period, some thin liquid fertilizer can be applied, often some fertilizer rich in growth elements.
The propagation of sage, including sowing propagation, cutting propagation and branch propagation, is relatively simple.
The common diseases and insect pests of sage are powdery mildew, stem rot, rust and leaf spot. The main pests are whitefly, scale insect, aphid and spider.
Basically, in order to make sage grow well, it is necessary to prune and pick the heart frequently to promote the development of new branches. And it can be pruned in time at the end of August in summer after the sage blooms, and it can bloom again in autumn.
