Bulb Planting Times, Depths, Spacing
and Growing Requirements
Bulbs, Corms, Tubers and Rhizomes for your GardenGrowing bulb type flowers is a very rewarding task, considering the ease of plantingand the resulting flower shows. If you didn't get exact planting directions with your bulbs, there are a few general rules of thumb that you can usually rely on when it comes planting and growing bulbs. 1. The pointy end always goes up! If you put the point down, your plant will still grow... but upside down. 2. Plant the bulb 2-2½ times deeper than the width of the bulb. |
3. Remove spent flowers promptly, but always allow the foliage to continue 5. As a general rule, the colder your climate, the earlier you plant your spring flowering bulbs. In colder northern climates, plant in September or October. How to Force Bulbs to Bloom Indoors and Out of Season |
