Poinsettia – Poinsettias prefer to get slightly dry to the touch on the soil surface before watering. Do not let them sit in excessive amounts of water, as the roots will rot. Do not let them wilt – they will drop leaves and flowers. Fertilizer is not necessary while the plant is flowering.
Amaryllis – Plant the bulb in good potting soil or compost, leaving the neck exposed. Water sparingly until the stem appears, then increase the watering amount as bud and leaves develop. For sturdier growth, place amaryllis in a brightly lit location. The bulb should produce flowers 7 – 10 weeks after planting.
Paperwhites – These can be grown in soil or in a tray of pebbles. If grown in soil, keep the soil moderately moist. If grown in pebbles or small stones, keep the water level just touching the bottom of the bulb. Put the planted bulbs in a dark area for a week or so, then move to a brightly lit location. Paperwhites should bloom in 4 – 5 weeks.
Christmas cactus – Keep the soil lightly moist while flowering, then let it dry out slightly after the blooms are done. Christmas cactus set blooms in response to declining daylight hours, so put yours where it will get a lot of natural light. Cool temperatures also help induce blooms.
