1, sowing in the whole soil
Impatiens likes loose and fertile slightly acidic soil, and is barren-resistant and adaptable. It is easy to survive and grow rapidly after sowing. Before sowing, arrange the substrate in advance, and then water the seedbed to keep it moist. Be careful not to have big clods. It's best to be flat and thin to avoid "eating seeds", and then cover it with a thin layer of soil of about 3-4 mm, paying attention to shading. Generally, seedlings will emerge in a week or ten days.
Seedling protection: In cotyledon stage, the substrate should be kept moist and not dry, but it should not be too wet and waterlogged to avoid "damping off". Water should be controlled at the true leaf stage, and the substrate surface should be dry before watering. After the primary true leaves are unfolded, they can be transplanted. Of course, if you plant a small amount, you can plant it directly, which is more conducive to root health and does not need transplantation.
2, transplant maintenance
Impatiens balsamina seedlings can be transplanted after growing 2-3 leaves, and the transplanting time does not need to be specially selected. Just pour enough water, transplant them with clods, and then gradually cultivate them. If it is planted in summer, it should be properly shaded for a few days, and then maintained normally after one week, otherwise it will not dry without watering. Fertilize properly after five leaves. You can apply decomposed rare human manure or other organic fertilizers once every half month, and then apply phosphate fertilizer and plant ash before and after pregnancy, so that impatiens can grow quickly and well and bloom more.

3, pest control
Impatiens balsamina has strong viability, good adaptability and few general diseases and insect pests. If the temperature is high and the humidity is high, spraying 800 times of 50% thiophanate-methyl wettable powder can prevent powdery mildew. In case of leaf spot, 50% carbendazim wettable powder with 500 times solution can be used for control. The main pest of Impatiens balsamina is red moth, and its larvae will eat the leaves of Impatiens balsamina. If this pest is found, it can be captured and killed manually. Impatiens like sunny terrain and loose and fertile soil, and can also grow in relatively poor soil.
4. Post-flowering management
After the flowers bloom, cut off the pedicel, and don't let the pedicel bear seeds, then the flowers will bloom more vigorously; Picking the basal flowers at any time will promote the top of each branch to blossom one after another, but it is easy to mutate. It can bloom in the first half of June and last for more than two months.

5. Seed harvesting
Harvest of Impatiens balsamina seeds: Impatiens balsamina seeds should be preserved every year, and because the fruits of Impatiens balsamina will bounce off and scatter the seeds in all directions, which belongs to mechanical propagation seeds, if flower lovers want to collect seeds, they can look at the bottom or around the basin or harvest them before the seeds bounce off.
Warm reminder that potted impatiens should pay attention to environmental conservation. First of all, there should be plenty of light. Secondly, pay attention to watering and fertilizing. Pay attention to the humidity of the basin soil. After planting, the main stem should be topped, so that the plant shape of impatiens will be more beautiful.
