What are the key points for watering potted plants? Learn how to grow potted plants well

Water potted plants according to the situation and master the amount of water. 1. Water according to the size, depth, and shallowness of the pot: water less in large pots, more in small pots, less in deep pots, more in shallow pots; 2. Water according to the material of the pot: water more in clay pots, less in ceramic pots, and even less in porcelain pots; according to the soil: water less in clay soil, more in sandy soil;

3. Water according to tree species: water more for broadleaf trees, less for coniferous trees, more for those growing well, less for those growing weakly, more for large trees in small pots, less for small trees in large pots; according to the placement location: water more in sunny, exposed spots, less in shady spots with little sunlight; water more in high, windy locations, less in low, less windy locations, water more when dry wind blows, water less when air humidity is high. 4. Water according to timing, and water quality is very important. To tell whether a bonsai needs water, tap the pot lightly with your finger: if it makes a sound, water it; if the sound is dull, do not water. Also, the water temperature should match the local air temperature; if too high, it will scald the roots, and if too low, it will freeze the roots.

Under normal circumstances, in spring and autumn the temperature difference is small and humidity is high, so water only when dry, regardless of time; in summer, when high temperatures cause rapid evaporation, water in the morning and evening; in winter, when plants are dormant, water at noon.

Avoid using water containing salt, alkali, or grease. If you have many bonsai, use pond or pool water; if you have few bonsai, you can use water left over from changing fish tank water or tap water that has been stored. Water until it flows out from the bottom of the pot, then after watering, spray the leaf surface to wash off dust and help photosynthesis. Generally use a watering can to water, and avoid using a garden hose to water bonsai directly, so as to prevent pot soil loss and endanger the plants' lives.
