How Deep Do I Plant Bulbs?
Great question. That depends on the size of the bulb. the rule of thumb for bulbing is to plant every bulb 3 times its height into the ground.
For example, a large Allium such as a Gladiator is about 2-3 inches tall (a very big bulb!), so you would want to have the base of that Gladiator Allium bulb about 6-9 inches below the surface. This allows for bulbs to root themselves properly and ensures strong upright stalks, it also ensure that your flowers will bloom that the proper time.
When Can I Plant Fall Bulbs?
Bulbing season is dependent on your region and the local weather, but you can plant bulbs up until the ground freezes. So as long as you can still work the soil without frozen chunks being a problem, its still bulbing season!
The cold period before the first hard frost is eessential for bulbs to root themselves. This allows bulbs to establish the roots they will need for large and strong spring flowers.
What Bulbs Work Well Together?
Floral displays are works of art, every one is different. However there are a couple good tips to follow:
- Plant Bulbs with shorter varieties in front (so you taller flowers don’t block smaller ones)
- Plant in large groups, I like to pack my bulbs in tight for a brilliant display
- Plan the bloom times:
- Every flower has a general expected week or month that it will bloom
- Plant early bloomers with late bloomers for constant color
- Plant Intentional Colors
- Mix colors evenly or plant massive color patches
Do Different Flowers Grow Well Together?
YES. When I worked as a landscaper/gardener, one of our favorite techniques was to plant large, late blooming Daffodils (Narscissus) with mid-spring blooming Tulips just above, then Grape Hyacinths (muscari) above the tulips and finally Crocus just below the surface.
This planting technique would create a constant floral display of changing colors and varieties of flower into early summer all in one tight packed spot (sometimes the garden gets so full you need to find tricks to make room .
