CLEAN DIRT
Leach container soils occasionally to remove any mineral salts accumulated from fertilizer and hard water, say experts with the University of Georgia Extension Service. Brown leaf edges and crusting on the sides of clay pots are two indicators of a salt problem. To leach large containers, water until the soil is soaked, then allow water to run slowly from your hose into the pot for about 20 minutes. For small pots, water each container until it drains from the bottom holes. Wait a few minutes, then repeat.
