Ornithogalums have never enjoyed the popularity that the other spring bulbs ejoy. This is probably because they are largely a white flower with only subtle differences in coloring. They should be more appreciated because they produce some of the longest lasting blooms of any flower in the spring garden and they can be easily forced.

The ornithogalum blossom spire begins to produce blooms from the bottom up. The florets are densely packed giving the blossom spire a look of opulence.

Ornithogalum ponticum Sochii is an extremely rare bulb that was first introduced in the early 1800s. It is native to Crimea. It is grown today commercially as a replacement for Ornithogalum magnum, a once popular pot plant whose bulbs are no longer grown. These plants can reach a height of 24 inches and are hardy from Hardiness Zones 5-8. For a presence in the garden, at least 10 bulbs should be planted in a group. When forcing place 3 bulbs in a 6-7 inch pot.

Planting Bulbs in the Fall for Glorious Spring Color

Bulbs are some of the easiest plants to grow. Fundamentally the process requires four steps.

1. Dig a hole.
2. Dust the hole with bone meal.
3. Place the bulb in the hole.
4. Fill the hole with soil.

There are, however, some additional refinements which help produce even more lavish results and enhance protection from critters.

First, bulbs can and should be planted deeper than the instructions you receive on the package labels. An easy way to remember how deep to plant the bulb is to think of a quarter. If the bulb you are planting has the same diameter as a quarter or less, plant the bulb 4 inches deep. If the bulb is broader than a quarter, plant it 6-10 inches deep. Large bulbs like some alliums, camassias, standard tulips and fritillaries can easily be planted 10 inches deep. As the soil compacts days, weeks and months after planting, it produces a thinner layer of soil on top of the bulb. Planting bulbs deep helps with critter control. Moles, voles, chipmunks and squirrels are lazy little creatures, and they don’t like doing a lot of digging to reach their food.

Second, bonemeal is a must. It is an excellent source of calcium and phosphorus which help the bulbs to form a strong root system and healthy stems. For large bulbs (those bigger than a quarter), use ¼ cup per bulb. For small bulbs, dust the entire surface or hole where the bulbs will reside.

Third, small bulbs should be planted in clusters of 10 or more – 1 inch apart. Large bulbs, like allium, can stand along, but create a much more pleasing presence in the garden when planted is clusters of 3-5. They should be separated by no more than 4-6 inches.

Fourth, bulbs usually multiply fairly quickly and once crowded will not produce blossoms. Plan to divide your bulbs in mid-summer to fall when the top growth has dried out.

These simple, easy, quick tasks are all that is required to produce a lovely bulb display year after year.

Planting Bulbs in Containers

If you live in Hardiness Zones 5 and higher all you need to do is mix some soil. Check out the soil mix described in detail in our Harvesting History YouTube video. Do not use prepared soil mixes.

The Best Soil Mix for Containers

Always plant bulbs more densely in containers than in the ground. Pots as small as 6-inches in diameter can have a showy presence on a deck, porch or patio.

You can use much larger pots and plant several kinds of bulbs.

Fill the pot half full, dust the soil surface with bone meal, arrange the bulbs on top of the bone meal and fill the pot with the rest of the soil. Dust the surface of the soil with more bone meal. Water thoroughly, but do not let the pot stand in a saucer of water.

If you live in Hardiness Zones 1-4, you must protect the pots by bringing them into an unheated garage or surrounding them with bales of straw. If you do not do this, the bulbs usually freeze and turn to mush.
