|Cultivation Details|| The Genus Clivia comes from South Africa. They grow naturally in the forests and bush lands of the subtropical regions from the Eastern Cape to the Transvaal. There are 4 species in this genus, Clivia miniata being the most variable and commonly grown. The other 3 species, C. gardenii, C. caulescens and C. nobilis are only recently becoming more known and widespread. Many Clivia growers/breeders are using the species to create interspecific (the crossing or breeding of two of the same species), hybrids. This is resulting in many varied shapes and colours in Clivia.
Growing Clivia here in our garden has been an adventure to say the least. I have had many failures in trying to find the right medium. I have tried many types of medium, buying ready-to-use at my local nursery and using straight from the bag, and making mediums from scratch with individual parts, (1 part sand, 1 part compost, 1 part perlite, 4 parts pine chips), going to make up the medium.
The best result thus far is a product called Debco Complete Orchid Growing Medium 5-10mm. I can pot anything from seeds to a 10-year-old bulb up into this medium with great results. After opening the back I spray the hose and wet the medium, leave for 1/2 a day and then I use this straight from the bag. It always help to add a liquid fertilizer to the pine chips too! In warmer areas, this medium is known to dry out. To slow the drying of the medium, add a small % of peat moss on top of the pot and wash in. This will create pockets of moisture to help sustain the Clivia until the next watering.
Clivia love food during the growing season. In the wild, Clivia grow where there is plenty of rotting vegetation and food is on hand, when it rains, at all times. With this in mind, I have been placing a small handful of cow manure on top of each pot in a little heap. This usually covers a 1/5th of the surface area of the top. I keep watering as usual until the food disappears. I will then place more on the top of the pot. This process that I have adopted and certainly helped my Clivia along.
Clivia are frost sensitive. They will do well in a fernery , plants well in under trees or under the back veranda, provided the frost does not reach them. In our region Clivia grow well and a double layer of 75% green shade cloth. Our summer sun and heat can crispy-fry most shade loving plants. You decide some thing about Clivia, the more Clivia plants you get, the better conditions you want to provide. Why? Because they get into your heart and you begin to love them. That is when the Clivia addiction starts!
Clivia make great friendships!
Happy Clivia growing.
