Frequently Asked Questions

Do all indoor bulbs need to be chilled before planting?

No, not all bulbs require a cold period. Bulbs like tulips, hyacinths, and crocus typically need a chilling period of 12-16 weeks to simulate winter before they can bloom indoors. However, bulbs such as amaryllis and paperwhite narcissus are tropical varieties that are ready to bloom without any pre-chilling.

Which side of the bulb should face up when planting?

Generally, the pointed, narrow end of the bulb should face upward, as this is where the leaves and flower stalk will emerge. The flatter, wider base is where the roots will grow. If you cannot tell which end is which, planting the bulb on its side is a safe compromise; the plant will naturally find its way toward the light.

How often should I water bulbs growing indoors?

You should water your bulbs immediately after planting to settle the soil. After that, check the soil moisture weekly; it should feel slightly damp but not waterlogged, as this can cause rot. If growing bulbs in stones and water, maintain the water level so it just barely touches the base of the bulb to encourage root growth without causing rot.

How long does it usually take for indoor bulbs to bloom?

The blooming time varies by species. Amaryllis usually takes 6 to 8 weeks to flower from the time of planting, while paperwhites take about 4 to 6 weeks. Pre-chilled bulbs (like tulips) that have completed their cold dormancy will typically bloom within 2 to 3 weeks once they are moved into warmth and sunlight.

Can I save my forced bulbs to bloom again next year?

It is difficult to get forced bulbs to rebloom indoors because the process depletes their energy reserves significantly. While paperwhites and tulips are usually discarded after flowering, amaryllis bulbs can be saved. To save an amaryllis, cut the spent flower stalk, continue to water and feed the leaves, and allow the bulb to go dormant in late summer before restarting the cycle.
