Find a sunny location to plant the gypsophila.
Till or dig up the soil with a garden fork to a depth of 12 inches.
Amend the soil with 3 inches of compost. Remove any rocks, sticks or dirt clods that you find. Level the soil with the back of a garden rake.
Add a dry, general all-purpose fertilizer to the soil before planting. Apply the fertilizer according to label directions.
Dig holes with a trowel that are slightly wider than the root ball, but keep the planting depth the same as the root ball. Space the holes 18 inches apart.
Insert the root ball into the planting hole and fill in the hole with amended soil. Firm the soil in place with your hands. Do not bury the root ball any deeper than it was originally growing.
Water the gypsophila until the soil is moist. Keep the soil moist throughout the growing season, but allow the soil to dry out a bit between waterings.
Lay a 3-inch layer of mulch around the plants. Mulch keeps the weeds from growing and it helps the soil retain moisture.
Deadhead the spent flowers to encourage new growth.
Feed the gypsophila once a month during the active growning months. Use an organic all-purpose fertilizer.
