Most houseplants require a constantly moist substrate. Watering frequency depends: on the species of the plant – the thick ones, fleshy leaves, like cacti, coarse plants, Guinean Sanseveria is watered less frequently than thin plants, delicate leaves, like a fern, begonia, slippers; from the season of the year – in winter, plant growth is limited, Therefore, they should be watered less frequently than in spring and summer; on the living conditions – an increase in temperature and light intensity increases the need for water. Plants in small pots and such, that have not been transplanted for too long require more frequent watering.
Plants are then watered, when the soil in the pot dries up, but it still has little humidity. The soil causes excessive drying, that instead of seeping in, the water leaks underneath. In this case, the pot should be immersed to the edges in a vessel with water. When the air pushed out of the root ball stops escaping, the pot should be removed and placed on a saucer at the destination. The condition is also incorrect, when the sealing of the soil surface in the pot prevents water from penetrating into the root ball. Then the surface must be loosened, and then immerse the pot in a vessel of water, like overdrying.
Water at room temperature should be used for watering, without chlorine (the municipal water supply is left open overnight, a wide dish). Watering with cold water causes some plants (np. African violet) the formation of light spots on the leaves. By watering, the space between the surface of the earth and the edge of the pot is filled with water, waiting (about half an hour) until the excess appears on the base, then decant the water from the tray. Plants with hairy leaves, like an African violet, gloxinia (garden syningia) – irrigate from below by immersing the pot in a pot of water to the level of the ground in the pot. After the soil has been watered, the pot is placed at its destination. Do not spray the leaves of potted plants standing in direct sunlight. Water droplets on the leaves in intense sunlight cause burns.
