1. Improper Water Management

Not all the plants need to water in the morning and evening, only when the water evaporates easily in the summer, then you need to water them more often. Don’t water the potted plants (such as Orchids) if they don’t have drain holes or when the dishes under the pots are storing water, because the roots will necrotize if soaking in the water for a long time, and will lead to imbalance of water absorption function, even the parts on the ground will wither and can’t be saved at last. Moreover, the plants will also wither easily if you forget to water them for 3-4 days in hot summer.

2. Improper Light Management

If you put the shade-intolerant plants (such as Codiaeum variegatum, Banyan tree, etc.) indoors for a long time, they will grow worse and worse because of lacking sunlight. Or if you put the shade-tolerant plants (such as Chinese evergreen, Ivy, Arrowroot, etc.) which can’t accept too much direct sunlight outdoors without a shade, they will hurt by the direct sunlight.

3. Improper Fertilization Management

Fertilizing should follow the principle of that fertilize small quantity but many times. A lot of quick-acting fertilizer (such as Urea, Hyponex, etc.) or some slow-release fertilizer, such as compound fertilizer will cause incurable injury because the concentration of the fertilizer is too high or the fertilizer is too close to the roots.

4. Improper Temperature Management

Don’t water the plants with very hot or cold water to avoid the harm caused by improper temperature. For example, if you place the Adiantum, Nephrolepis cordifolia in a low-temperature air conditioning room, they are likely to get hurt by the low temperature. Furthermore, it will also lead to poor growth of the plants if the temperature in the airtight room is too high. For example, it is not suitable to place the African violet and gloxinia in the bathroom.

5. Improper Pruning Management

Since different kinds of plants with different regeneration capacity, over pruning will result in big loss of nutrient, serious stagnation of plant growth or poor blossom and fruit. If you don’t prune the plants (such as Orange-jessamine, Serissa serissoide, Golden Dewdrop, Golden Chinese banyan, etc.) for a long time, it will lead to messy shape of the trees and make the lower branches hard to absorb sunlight, which will result in the deadwood phenomenon.

6. Improper Disease Management

Pathogen infection is invisible to the human eyes. We needs to act as soon as possible to prevent or isolate the sick plants if the symptoms appear, such as toxinosis, blight, etc. the infected plants, branches and leaves should be promptly removed, or all the plants will die once the diseases spread, and even infect the different types of plants.

7. Improper Pest Management

It is obvious that pests will persecute the appearance and shape of plants. We can’t indulge them because they have the ability to breed fast. Sometimes, aphids and scale insects acting as insect vector will cause intercurrent infectious diseases, so we should choose agentia seriously to prevent that.

8. Misplace Fermented Leftovers

If you place or pour the coffee grounds, soaked tea leaves, food residue etc. directly on the topsoil of the potted plants, those organics which haven’t sufficiently rotted, fermented, resolved will cause the competition about absorption of nitrogen fertilizer between microorganisms and plants, and lead to malnutrition of the plants, and the plants may die for infecting more pathogens.

9. Having Chosen a Wrong Soil Medium

If the soil hasn’t been disinfected, it will contain a lot of pathogens and worm eggs. Moreover, we shouldn’t choose the soil medium which is not suitable for the plants themselves to cultivate the plants. For example, we should choose sandy loam with high drainage ability and good ventilation to plant cacti, but if you choose clayey soil with high water holding capacity to plant them, it will cause poor growth of the pants.
