What principles should I master when watering the vegetable garden?

Potted flowers should be watered according to the principles of "dry thoroughly" and "wet when dry".

These watering principles are summarized according to the water-loving habits of the flowers and trees. Potted flowers such as Chimonanthus praecox, Plum Blossom, Hydrangea, Dahlia and Geranium, which like to be dry and afraid of waterlogging, should be watered according to the principle of "dry thoroughly and drenched thoroughly". Don't water the pot until it is completely dry. "Soak thoroughly" means not watering "half water", but letting the basin soil be completely wet up and down. If it is not poured thoroughly, the root tip can't absorb water, which will affect the growth. However, thorough irrigation does not mean leakage. Frequent leakage and excessive loss of fertilizer will also affect growth.

Rhododendron, camellia, rose, gardenia, Milan, Nandian bamboo, hydrangea, evergreen and other flowers that like to be wet but not waterlogged should be watered according to the principle of "seeing dry and seeing wet". When the surface of the basin soil turns white, water it until it is wet. Don't wait until the soil in the basin is dry, and you can't water it. To make the basin soil dry and wet alternately, it can neither be dry for a long time nor soaked frequently, but dry and wet alternately.

Potted flowers, such as Pteris vittata, calla lily, anchovies, etc. That's like a flood. Water should be done according to the principle of "wet rather than dry", and the basin soil should always be wet and not dehydrated.

Flowers such as Pinaceae and succulent flowers should be watered according to the principle of "dry but not wet" because they like drought. They should be watered only when they are dry, and they can't be flooded.
