Forcing Bulbs Indoors #Flowers
Most bulbs will do well if grown in potting mix. Always start with clean pots and fresh mix.
Step 1: In autumn, purchase bulbs from a garden center, nursery, or mail-order source. Plant bulbs of your choice in any type of pot with a drainage hole. Choose a pot that's at least twice as deep as the bulbs to allow for proper root growth. Fill the pot half full of soilless potting mix.
Step 2: Place as many bulbs as possible in the pot, without letting them touch. A 6-inch-wide pot holds up to six tulips, three narcissus (daffodils), or 15 minor bulbs, such as crocuses or grape hyacinths.
Step 3: Cover the bulbs with potting mix, leaving their tips showing. Water the bulbs thoroughly. Label with name and date; loosely cover pot with a paper bag. Place in cool (35 to 45 degrees F), dark storage for chilling. See our bulb-forcing timetable for chilling time.
Step 4: Check moisture in pot periodically. Keep soil damp but not wet. When chilling is complete, you'll see roots poking out of the bottom of the pot and green sprouts emerging at the bulb tips. It's time to move the potted bulbs into a warm room.
Step 5: When flower buds form, move potted bulbs into a sunny spot. Keep the soil damp. When flowers appear, move the pot out of direct sun to make the blooms last longer. After the blooms fade and wither, toss them (bulbs and all) into the compost. Most forced bulbs have used up their energy and won't bloom again.
