Plant in odd numbers, in groups of at least five to ten. The distance between the bulbs should be around 12 cm. Planting depth should be three times the height of the bulb. Dig a planting hole and loosen the soil with a spade. Then mix in some Zetas bulb fertilizer into the soil and cover the bulbs. Spray tulips, snowdrops, and crocuses with TRICO Garden to keep them safe from hungry deer. Pinch off the flower when it has finished blooming, let the foliage wither. Longevity depends on weather.
