When do I plant my spring-flowering bulbs?
It’s bulb-planting season! Now is the time top to be planting for spring-flowering bulbs! Fall-planting bulbs need to be planted in the ground, generally speaking, about 6 weeks prior to the first hard frost. It is best to wait until the outside temperature does not reach 65 degrees anymore. Bulbs such as tulips, daffodils, narcissus, hyacinths, iris, allium, fritillaria, and scilla require a cold period in order to form roots, and based on lighting and warmth conditions will bloom in the Spring.
How deep should I plant my Fall bulbs?
The basic rule of thumb, is that the hole should be at least three times as deep as the height of the bulb. Use the chart above for the required planting depth of your bulbs. Don’t worry about your bulbs being planted an inch or two deeper than recommended; in most cases this provides the bulb with a little extra protection.
