Different seasons require different care of your plants, particularly plants in pots. For most Clivia, winter is a time of a degree of dormancy. There is very little root growth or leaf growth during this time.
Clivia need about 6 weeks of cold weather in order to flower. Often species plants such as Gardenii and interspecifics may be flowering during this time.
I have heard of growers with plants in pots under cover who do not water at all over winter. I do still water my plants but not as often as I do during the growing season. With plants in pots under cover, I water around every 10 days though I always feel the potting mix to determine how dry it is first. With my plants in pots that do get rained on, I may only water every 2 – 3 weeks depending on how much rain we have had and how dry the mix is.
Clivia planted in the garden probably will not need watering over winter. There will be enough moisture in the ground to keep them happy. If you are in an area of low rain fall, you may need to give them the odd watering.
Repotting and Dividing
You can repot or divide a Clivia any time of the year though winter is not the best time as the plant will take longer to establish due to the low root growth during the cold season.
I don’t fertilise my plants over winter as I want them to go through their dormant period and not be induced to grow.
Pests and diseases
Mealy bug tends to disappear of lessen during winter as they prefer a warm humid environment. Having said that, it is still important to keep an eye out for Mealy bug as well as snails, slugs, earwigs and other creepies.
As berries are ripening and colouring up, often mice or possums think they look like something that may be good to eat, and try to eat them. Usually you find berries missing and seed scattered around where they have been dropped when deemed inedible. If the berries are important to you as you wish to harvest seed, it may be worth covering the berries with netting to protect them.
Watch for water dripping from trees or bushes in the garden. Normal dripping is fine but sometimes the plant may be in a position where it gets extensive water pouring down on it. This can damage leaves and cause rot.
Also watch for leaves and debris building up in the leaves of your plant. After autumn with all the trees losing their leaves, these can easily catch around the base of the plant as well as in the leaves. These leaves then get soggy with the rain and can cause rot.
Winter is a great time as it means we are closer to flowering season.
