They should be planted where there is full sun or only filtered shade to allow for the best bloom. Typically only snails and slugs pose a threat to Gazania in mass plantings which provide daytime shelter. Utilize procedures recommended for mollusk control. Occasional infestations of aphids do not create a serious problem. Perhaps the biggest challenge is keeping large plantings weed free during the establishment period.
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.
