Repotting Houseplants
Now through September, repot houseplants that have become root bound in their containers. Place in a larger container, using sterile soil mix to supply aeration and moisture-and-nutrient holding capacity for healthy plant growth. Crushed egg shells worked into the soil will supply calcium for plant growth. If plant is root bound in original container, use a sharp knife to slice into the root ball. Cut into root mass of ball about an inch on 4-6 inches spacings around the ball. Loosen soil of small plants with your fingers.
