Generally speaking, Impatiens is better to feed. As long as you give it enough water, it can't be too much. Everything should be just right. When the Impatiens is growing hard, it should have enough water. It's better to water it every day. Of course, the temperature is high in summer, and the soil is easy to dry, so it should also be watered more. When it's rainy, it's necessary to pay attention to drainage. After raining, it's necessary to pour the water out of the flowerpot in time, so as not to rot the roots of plants due to too much water. If you want to grow Impatiens healthily, you need to water them properly: too little water will make the leaves curl; too much water will make the roots of Impatiens rotting.
Everything grows by the sun, so does the impatiens. Without enough light, the leaves may curl. The plants are positive. The fingernail grass should be exposed to sunlight for at least 4 hours every day. Especially when it is long and blooming, it needs sunshine to protect it and ensure the normal operation of photosynthesis and metabolism. Of course, when the hot summer sun is in the sky, it should be moved to the house, because what it needs is astigmatism, not direct sunlight. The light is the same as the water, need moderate sunshine, lack of sunshine may cause leaf curl, too much sunshine may cause leaf wilt
Insect damage is a disaster of Impatiens. Aphids or whiteflies not only eat the leaves, roots and flowers of plants, but also leave their eggs on the leaves and cause the leaves to curl. If you take good care of your Impatiens without water or light, you can break open the curly leaves to see if there are eggs or larvae of aphids or whiteflies. When pests are found, they can be caught by hand or pesticide can be used. If you just plant a Impatiens on the balcony, you can catch insects by hand. If you plant a large area, you need to spray some medicine.
