Growing & Propagation
Clivia grow extremely well as a house plant since they are tough and resilient and thrive even when neglected. They do not like direct sunshine but will grow well in partial and dense shade, this makes them suitable too be grown in the home where other house plants will fail.
Clivia roots need a lot of air around them, so the compost must be well drained and slightly acidic. The ideal medium is 2 parts medium grade pine bark 1 part ericaceous compost 1 part fine horticultural grit. All these ingredients are readily available at most Garden Centres.
A low phosphate feed is recommended from early February to late September every 2 weeks. Our own formula NPK is 18:6:18 plus trace elements and is readily available at all our flower shows and online.
Water liberally from Spring to Autumn decrease the amount in winter when growth slows down or stops.
Flower initiation and growth
Clivia need a cold period in the Autumn to aid flowering in Spring so, place them in a shady spot outside in early September and return inside mid November before the first frost occurs.
Clivia like other members of the Amaryllidaceae family like to be tight in their pots. Pot on into slightly larger container every 2 years, this is best done June & July.
This is usually done with 2 simple methods:
Seeds will not form on your Clivia if pollination has not taken place. In the wild pollination is usually carried out by insects and birds. To pollinate your Clivia you need to transfer the pollen from one flower to another for 5 consecutive days using a soft fine paint brush. After pollination the flower quickly falls from the flowerhead. If pollination is successful a green swelling can be seen where the flower was attached. This quickly develops into a green berry the size of a grape. Leave the berry on the flower stalk until it changes colour to yellow, peach or red. It is then ready to be collected, cleaned and sown. The colour of the berry generally indicates what colour the flower will be.
When sowing Clivia seeds make sure the darker part is uppermost, press the seeds halfway into the compost, but do not cover, germinate in the usual way bit not in direct sunlight.
Division of offsets
This is best done after flowering to late summer. Carefully wash away the compost so all parts are clearly visible. With a clean sharp knife cut the offset off close to the mother plants rhizome. Pot up using well drained compost and water well with a fungicide. this method of propagation produces plants identical to the mother plant.
