The best time for sowing the seeds is the early, spring season. You can also sow the seeds after the frosting winter season. However, sowing seeds during the warmer, spring season helps the plant to bloom early.
Gazanias need minimal soil nutrition. They grow well in fast-draining, sandy soils. Unless you have a particularly under-nourished soil bed, fertilizers are not needed. However, feeding the soil bed, once before sowing the seeds is advisable. Light dose of an organic fertilizer to the planned, sowing site is sufficient. After this, you need to fertilize the soil just once, every year. You should use slow-release fertilizers. Don稚 use fertilizers that have heavy concentration of nitrogen.
Water the site chosen for sowing the seeds. Allow the soil bed to drain-away the excess water. Dig-up the fertilized soil bed with your hands. Every planting hole should be about 3-mm deep. Ensure that you maintain a minimum distance of about 8 inches between the holes. Fill each hole with gazania seeds and cover it with the dug-up soil. Lightly, clamp upon the moist soil.
Watering & Mulching
Watering the gazania seeds once, every week is sufficient. These plants need a moist soil but without any waterlogging. While watering, ensure that you water the plants slowly, letting the soil bed dry before spraying it again. Once the seedlings begin to sprout, weekly watering can be further slowed down to watering every 8-to-10 days. You can also mulch the seedlings to ensure that the soil retains its moisture and drains well. Use organic compost for mulching young gazanias.
Gazanias are particularly suited for creating a fast-spreading garden spread. They self-seed and grow very quickly. However, you can fasten the propagation process. For this, systematic division of young gazanias is needed. Choose gazanias that are about 10 inches tall. Using gardening scissors, cut through the basal stem, dividing it into two halves. Each half will now grow as an individual plant.
You need to prune-off the spent flowers, once the flowering season is over. These can be used for composting. Deadheading weathered flowers stimulates growth. For pruning thick clusters of seasonal foliage and old stems, use bypass pruners.
