Wind blown weed seeds, especially bermuda grass, can be a real nuisance. If utilizing a seeding method, wait until the plants have germinated and become somewhat established. Rogue out young weed seeds in the mean time. Eventually, pre-emergent herbicides may be utilized to prevent weed invasion. Should an outbreak of bermuda occur, a selective herbicide for grasses may be used to curb the invasion.
Gazanias respond well to a spring application of a complete, slow release fertilizer.
A light application of a water soluble fertilizer will help to maintain color and vigor throughout the balance of the year. Gazanias normally do not require any pruning unless they grow out of bounds. Those plants should be cut back just prior to the flush of spring growth. Clump forming plants also may be lifted and divided if necessary at this time. Respace the plants to allow for future growth.
