Phlox Flower Bulbs

About Phlox Flower Bulbs

Phlox Flower Bulbs grow in full sun, partial shade positions. Expect 24 to 36 inches or varies at maturity. Flowering runs late summer through early fall or spring through late spring. The figures below are the ones on the packets in this group; each product page carries the exact numbers for that variety.

When to plant

Plant in spring. Bulbs go in while the soil is still workable, and want to be in the ground long enough to settle before it freezes. Hardy in zones 3 to 8 — your local frost dates decide the exact week.

Where to plant

Choose a site in full sun, partial shade. Water needs are average once the plants are established. Drainage matters more than anything else: bulbs sitting in wet winter soil rot. Allow 2 feet or 2 to 6 inches between plants so air can move between them. Plan for 24 to 36 inches or varies of growth when you place them in a bed or border.

How to plant

Set the bulb 2 to 5 inches or top of root ball should be even with soil surface deep, pointed end up, spaced 2 feet or 2 to 6 inches apart. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.

How to care

Keep watering average, at the base of the plant rather than over the leaves. In zones 3 to 8 these come back each year: let the foliage die down naturally after flowering, since that is what feeds next season's growth. Flowers appear late summer through early fall or spring through late spring; cutting or deadheading regularly keeps more coming.
