Do you want plant Autumn Crocus? Let's do it!

1. Before the ground freezes in the fall, early bulbs can be planted most anywhere, except in the dense shade on the north side of buildings.
2. Ideally, plant crocus corms 6 to 8 weeks before a hard frost is expected and when soils are below 60°F(16°C). This is usually during September and October in the North, and October and November in the South.
3. Make sure the soil drains well, because bulbs will rot in soggy ground.
   Work in organic matter such as compost, peat or a substitute, such as shredded leaves to a depth of at least 10 inches.
4. Plant crocus bulbs 3 to 4 inches deep (with the pointy end up). After planting, water well.
5. Plant bulbs in groups or clusters rather than spacing them in a single line along a walkway or border. Single flowers get lost in the landscape. Plant a few inches apart, and plant in groups of 10 or more.
6. Consider planting crocuses in lawns and meadows where they can form carpets, or mass them in the front of flower beds along the edge.
7. Plant taller bulbs and spring-flowering shrubs behind the early bulbs for color contrast.
