Planting Instructions
Planting Crocus Bulbs - How to Plant Crocus BulbsFor starters, it should be noted that crocus bulbs are not officially flower bulbs at all, but rather, corms. A corm is best described as a “fleshy, bulblike base of a stem”, but to most gardeners, this distinction is a mere technicality and for the sake of this discussion we will refer to them simply as “bulbs”. Crocuses are hardy plants belonging to the Amaryllis family and are native plants chiefly of the Mediterranean region. They're some of the first flowers to pop their heads through the winter snow. You can expect to see crocuses blooming in February and lasting through about March. They're classified as hardy perennials, which means that they come back every year and hold up well in colder conditions. Crocus bulbs continue to grow in popularity, not least because they are among the easiest of the fall planted bulbs to cultivate.
When to Plant your Crocus Bulbs:
Plant crocus bulbs in fall, six to eight weeks before a hard frost is expected and when soils are below 60 degrees F. This is usually during September and October in the North, and October and November in the South.
Where to Plant your Crocus Bulbs:
Crocuses prefer sunny spots, but will also usually tolerate some filtered shade. As crocus bulbs are typically planted by the hundreds or thousands to produce a lush groundcover or border, plant the bulbs very densely to achieve maximum affect. The standard planting recommendations are 2 or 3 inches apart and 2 or 3 inches deep. If planting a large area, we recommend digging light trenches and spacing the crocus bulbs in compact rows. The crocus bulb (or corm) should be planted pointy side up and root side down.
How to Plant your Crocus Bulbs:
Once placed in the soil, we recommend adding some fertilizer and/or bulb food to the crocus bulbs. It’s also helpful to water moderately until frost. If your soil is reasonably rich and well drained, these final steps are not required, but as with all flower bulbs, crocus bulbs will usually reward a little “TLC” in the fall with bigger and bolder bloom come springtime.
How to Care for your Crocus Bulbs:
Once planted, they require little or no maintenance or upkeep. Crocus bulbs need not be disturbed for some years. In fact, as long as they flower freely, unless an increased stock is desired, they should be left alone. The other primary beneficial attribute of crocuses is that they are incredibly early bloomers – even emerging sometimes through snow as an audacious harbinger of spring! -
