Waiting for bulbs to come up and bloom each season comes with anticipation. They produce beautiful results — even in the hands of a gardening novice. All you have to know is when and how to plant your bulbs.

From to planting and maintenance requirements, here’s what you need to know:

Are there different types of bulbs?

Bulbs come in two basic types, and they’re categorized by their hardiness and planting conditions.

  1. Hardy (spring): Hardy bulbs are planted in fall, spend winter in-ground and bloom in the spring. Plant them once evening temperatures reach 40 to 50 degrees or about 6 to 8 weeks before the first frost.

    In warmer climates, hardy bulbs may need to be kept in the refrigerator until planting conditions are ideal.

  2. Tender (summer): Tender bulbs are planted in spring and flower in summer. Wait until any threat of frost has passed to plant them. If necessary, store in a cool, dry place until planting is feasible.

Bulbs have simple but specific planting requirements.

Bulbs can be planted almost anywhere, but they thrive under certain conditions; Loamy soil with ample drainage is preferred, as it prevents rots. Supplement with fertilizer or organic material, such as compost or peat moss, to increase nutrients and drainage.

  • Plant bulbs two to three times as deep as they are tall, pointy ends up with the roots facing downward.
  • Add a light layer of mulch to prevent weed infestation.
  • Cover with mesh to deter animals from digging.

Bulbs should receive at least six hours of direct daylight per day.

You’ll need to give the bulbs “rest” during their off-season.

When blooming is complete, trim only the flower stem, leaving foliage intact to gather energy for the following year.

In colder climates, dig up tender bulbs and store them until after the last frost of the season. In warmer climates, tender bulbs can stay in-ground with a layer of mulch insulation from chilly weather.

Hardy bulbs that are planted in warmer climates do best if they’re dug up and stored.

Bulbs should be stored in a dark, dry, cool area (ideally 50 to 60 degrees), kept moist, but not allowed to mold. Discarded rotting bulbs.
