Use 5-10g for small bulbs or corms, 10-20g for large bulbs or tubers. One palm full is approximately 10g.
Place Bulb Starter into the base of the planting hole, backfill and water.
Follow the planting guidelines supplied with your bulbs, corms or tubers. Generally bulbs are planted two or three times their own depth into the soil with the bulb head facing upwards, ensuring there are no air gaps near the bulb.
Not all bulbs overwinter well in the ground and some summer flowering bulbs, for example Dahlias, should ideally be removed and stored in a dry, frost free place over the winter months.
