Time to Plant Bulbs!
Although we are approaching the end of October there is still time to plant garlic and spring flowering bulbs. A little effort now will reward you with beautiful flowers next spring and some tasty garlic by mid-summer. The soil temperature in my raised beds is still above 50 degrees, soil moisture is more than adequate and those conditions are ideal for root development on bulbs. I planted garlic about two weeks ago and the cloves have already sprouted a healthy bunch of white roots more than one-inch long. I know this because some critter was digging in my garlic bed and it unearthed a few cloves. The cloves will probably also grow green shoots, a few inches tall, before the ground freezes. When that happens I will mulch them with a few inches of clean straw. I usually harvest garlic the second or third week of July. Remember to plant only the biggest individual cloves from each bulb.
Spring flowering bulbs fall into two general categories; the major and minor bulbs. Major bulbs include tulips, daffodils, hyacinth, large alliums and Frittilaria (Crown Imperial) but there are also some dainty versions of daffodils. Minor bulbs include crocus, snowdrops, winter aconite and muscari. The large bulbs are usually planted individually using a bulb planter but the minor bulbs are most often planted in groups of ten or more.
Ready for bedding
To prepare a planting bed for minor bulbs, thoroughly till the soil to a depth of six inches, working in a two-inch layer of compost or peat moss. A good place to do this is where you previously grew a bed of annual flowers. Now that the spent annuals have been removed and composted, the soil should be in good shape and easy to work. Sprinkle a cup of dried blood and a cup of bonemeal for every ten square feet of bed (roughly three foot by three feet square) on top of the tilled soil and rake it in.
Or you can substitute one cup of 5-10-10 fertilizer or four cups of composted manure. Plant the minor bulbs with the pointy side up about one inch deep in the soft soil. Press them firmly into the soil and make sure they are covered by about an inch of soil on top. Cover the bed with a two inch layer of mulch and you are done!
Next spring you can enjoy the bulbs in the spring and afterwards you can carefully tuck in some annuals or perennials around them when the blossums fade. Select taller plants that will cover the fading bulbs foliage with their leaves as they grow. Summer or fall flowering perennials will not compete with the bulbs. This bulb/perennial bed should last for several years at least, with just minor maintenance.
The major bulbs are usually planted individually by cutting a six-inch deep or deeper hole with a bulb planter. Major bulbs should be planted at a depth that is at least twice the width of the bulb. Therefore a two-inch thick daffodil bulb should be planted with the tip of the bulb at least four inches below the soil surface. Make the planting hole about an inch or two deeper than you need and place a couple of inches of soft soil at the bottom. Put a tablespoon of 5-10-10 or one tablespoon each of bonemeal and dried blood in the bottom of the hole. Fill the hole and cover the planted bed with two inches of mulch.
Remember to plant bulbs where they are within easy viewing of the house during nasty spring weather. Remember also that deer will eat tulip and most other bulb foliage as though it is spring candy in April and May! Daffodils are deer proof however and they should be planted somewhere where they may remain to spread. Tulips generally only persist for a few years before they need to be dug up and replanted.
