Cactus
Cactus has the ability to store water in its stem, often preferring a dry environment and a well-draining substrate. Therefore, placing the plant on an uncovered balcony, a place that often receives heavy rain, can cause the soil to maintain moisture for too long.
Cactus and many succulent plants need well-draining substrates. Too moist soil for a long time can damage the roots, leading to root rot and weakening of the plant.
Homeowners can put cacti in a sheltered position, still receiving natural light but avoiding direct rainwater.
Stone lotus and jujube
Stone lotus, echeveria and many succulent plants also need to be limited in exposure to prolonged rain. The characteristic of this group of plants is that the leaves or stems have the ability to store water, so they are not suitable for constantly humid substrates.
Note that watery plants generally prefer a dry environment, low humidity and good drainage. When it rains heavily, homeowners should check the soil's humidity before replenishing water.
Small potted plants
Small pots placed directly under the rain also need to be noted. Due to the small amount of substrate, rainwater can quickly make the entire pot wet. If drainage holes are blocked or the pot is placed close to the floor, water may stagnate longer.
The pot needs to have a suitable drainage hole. The homeowner should check the bottom of the pot and avoid letting water stagnate in the hopper at the bottom.
The tree has roots sensitive to waterlogging
Some trees cannot withstand prolonged flooding. When the amount of water in the substrate is too much, the air space around the roots is reduced, making the root system difficult to absorb oxygen and easily damaged.
Prolonged waterlogging can cause yellow leaves, slow growth, and root rot. Therefore, for potted plants placed in locations that are frequently exposed to rain, drainage capacity needs to be checked first.
Trees are weak or newly transplanted
Trees that are weakening, both replanting or treating the root system, should also be protected from heavy rains. Homeowners can place trees in a sheltered, ventilated area with sufficient light suitable for each type.
Do not assume that when it rains, the plant does not need care or all the plants must be brought into the house. Planters check the moisture content of the substrate before watering, instead of applying a fixed watering schedule.
