Amaryllis 'Black Pearl'

Autumn-Winter · Indoors

Feed indoor Amaryllis bulbs

As soon as foliage starts to emerge from the bulb, feed every 2 weeks with general houseplant fertiliser when you water. If you plan to keep the bulb for next year, keep feeding for 6 weeks after flowering is over.

Autumn - early · Planting

Plant indoor amaryllis bulbs

Use a pot with drainage holes a little larger than bulb. Half fill with compost and place bulb on top. Cover so that two-thirds is above the surface. Water sparingly until stems appear. Flowers 6-8 weeks. Take care: can become top heavy and topple over.

Autumn-Winter · Planting

Protect from toppling over

Once the stem(s) grows tall and large flowers appear, the plant becomes top heavy. It can topple over, or the flower stem break. Avoid this by placing the pot inside a second heavy ceramic pot, or stake the stem to secure it before flowers form.

Spring-Autumn · Indoors

General houseplant fertiliser

Feed this plant with a general houseplant fertiliser.

Spring-Winter · Indoors

Keep moist, but not standing in water

Keep moist at all times. Water more sparingly in winter, keep the compost just moist.

Spring-Winter · Indoors

Soak completely when watering

Water until water comes out of the bottom of the pot. Leave for 30 minutes or so until the compost is fully moist, then pour away the excess water so the plant pot is not standing in water. (This avoids waterlogging which can cause "root rot".)

Spring - late · Outdoors

Feed with slow release fertiliser

Apply a general purpose slow release fertiliser, spreading it around the root area of the plant as it is coming into growth. (Or apply a liquid feed at regular intervals throughout the growing season.)

This is a simple way to provide a nutrient boost as a single annual procedure.

Spring-Autumn · Outdoors

Water during dry periods

For plants in the ground, when there has been little or no rain for a period of 7-10 days and the soil is dry, give it a deep watering and repeat weekly until there is a downpour of rain. Check plants in pots more frequently, especially in hot weather.

Winter · Planting

Keep amaryllis plant for next year

After flowering cut stems back to the bulb. In summer, put outside or in the greenhouse. In September, cut off foliage, move to a well-lit cool place indoors (13°C) for 8-10 weeks, then move to a warm spot to grow. Re-pot rarely (every 3 years or so).
