Conservation methods of impatiens

First, cultivation is the basis of conservation, maintenance is the follow-up work of cultivation, therefore, if we want to preserve impatiens, we must first cultivate it, let's start from its living habits.

Impatiens like sunny topography and loose and fertile soil, and can also grow in poorer soil. From the initial length of 8 cm to 20 mi 30 cm, after planting, the main stem of the plant should be topped to enhance its branching ability, and the plant shape should be plump. After 5 leaves, putrefied rare human feces and urine were applied every half a month, and phosphate fertilizer and plant ash were applied before and after pregnant buds. After the flower blooms, cut off the pedicel, do not make it seed, the flower blossoms more prosperous; the base flowers are picked at any time, which will promote the top of the branches to blossom one after another, but it is easy to mutate.

If Rain Water should pay more attention to drainage and waterlogging, otherwise the roots and stems are easy to rot. Fertilization should be diligent after planting, and special attention should be paid not to dry or wet. Never water wilting plants in the hot sun in summer. Especially in the flowering period, do not suffer from drought, otherwise it is easy to fall flowers.

Remove diseased leaves and diseased plants and destroy them centrally so as to reduce the source of infection.
