Hello from HealthyHousePlans.com!
Today’s video will guide you on how to leach your houseplant soil effectively, a process often essential for removing toxic salt buildup. Toxic salt buildup can appear as a white crust on the pot’s edge or cause brown leaf tips and root rot, affecting plant health. Regular leaching is especially recommended when bringing a new plant home, as nursery plants may carry residues from artificial growth hormones and fertilizers.
Leaching is simple for smaller plants, which can be done in a sink, while larger plants may require leaching outdoors or in a tub. Slowly run at least three times the volume of the pot’s capacity in tepid water through the soil to flush out salts and chemicals. This process may need repeating if soil is particularly dense. After leaching, allow the plant to drain well before placing it back in its desired spot.
