Tips on Growing Fall Planted Flower Bulbs

When you receive your spring bulbs (tulips, daffodils, etc.) keep them in a dry, dark, cool place until ready to plant. They need air circulation so they will not collect moisture and rot. Planting times can vary from early October in the North to mid-to-late November in the southern regions. A good rule of thumb is to plant them about 6 weeks before the ground is frozen or after the first hard freeze. For more information and a planting depth illustration, see pages 14-16 of our Planting Guide.

Soil Preparation for Bulbs

A compost enriched, well-drained soil is best. Incorporate a good quality organic compost as needed. Yum Yum Mix® is recommended as an excellent source of nitrogen, phosphorus and potassium needed for strong plants and healthy roots. Mix a small amount into the bottom of the hole before planting your bulbs.

Many bulbs prefer full sun exposure. However, Muscaria, Allium, Galanthus, Hyacinthoides, Scilla and many Daffodils will tolerate partial shade and bloom well. Pink daffodils will hold their color longer if planted in dappled shade or morning sun/afternoon shade.

After planting, add a top dressing of compost or other organic material and water in thoroughly. If your winter is dry, water every three to four weeks throughout the winter and add more mulch if necessary.

Protect your Bulbs

Apply Chase Mole and Gopher Repellent to the surface of the ground to protect bulbs from these burrowing mammals. As bulbs sprout, use our Deer Off Repellent to prevent deer and rabbits from browsing your spring blooms.

After your Bulbs have Bloomed

Once your bulbs have bloomed, allow the bulb foliage to brown and fade naturally, since the leaves are feeding the bulb in the ground. Removal of foliage weakens the bulb and leads to fewer blooms the following year. Planting your bulbs amongst your perennials is one way to conceal the dying bulb foliage. The perennials begin to grow and fill out as the bulb foliage dies back. The perennials will then provide foliage and color in the garden from late spring through the summer and into fall. Regular fertilization with balanced organic or natural fertilizer and a re-application of mulch each fall will insure more and more beautiful spring bulb blooms for many years!

    Comments about High Country Gardens Allium ostrowskianum Bulbs:

    I planted this on a south-facing slope just above a rock wall. Lots of early blooms in the garden this year and this Allium was no exception. April bloom carried on for some time.

    Coloring is attractive and will improve as they spread in future years. It's odd, however, that the leaves seem to be larger / higher than the blooms, as if it got itself backwards.

    Q & A

    USDA Hardiness Planting Zones

    To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

    • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
    • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
