Chilled thrills in the Western Cape
- Have faith in your fynbos and head over to your GCA Garden Centre to checkout new protea hybrids and visit some old faves too. Leucospermums (pincushions) and leucadendrons are stunning choices you can go bos with in the garden. Remember, proteas grow in pots too!
- Aunt Gale’s wind is always around the corner so make sure all ties and stakes supporting young trees and roses are super secure. You may also want to check your garden furniture and make sure that nothing will end up in your neighbour’s yard.
- Avoiding flooding at home by clearing drains and gutters of old plant material.
- Begin winter pruning on vines, peach, plum, and apricot trees. Visit your GCA Garden Centre for products to spray on dormant trees after pruning.
Plant flowers from Wonderland
- Pansies and Violas: These annuals are perfect to plant as borders and edgings, in window boxes and containers. Position them where they receive full sun in winter but partial shade in spring and early summer, to give them a longer lifespan. They like fertile, composted soil with good drainage and regular watering.
- Snapdragons: These short-lived, yet super-cute perennials are ideal in mixed border gardens, flower boxes, and as potted patio décor. Bright snapdragon flowers will bloom profusely all winter long in full sun to partial shade. Begin germinating seeds indoors and when they’re ready, pop them into nutrient-rich soil that drains well.
Blooming muses to plant: Primula, primrose, calendula, stocks, gazania, poppy, bellis, alyssum, conifers, hellebores, narcissi, Camellia, Erica, pincushion, and ornamental grasses.
Triumphant cold troupers to plant: Abelias, Elaeagnus pungens ‘Variegata’, Pittosporum tobira, P. tenuifolium, rosemary, confetti bushes, Melaleuca bracteata ‘Johannesburg Gold’, and holly.
Artsy-potsy plant pick: Lewisia is one tough babe and will handle pretty much everything winter has to throw at her. She likes sun or partial shade, good drainage, but not the richest of soil. Water her moderately and deadhead spent blooms. She’ll reward you with gorgeous rosettes, slender stalks, and pastel-pink flowers for patio pots and just about everywhere else really!
- If you live in a frost-free area you can begin pruning roses in June.
- Very chilly and frost-prone areas should wait until the 2nd week of July.
- Everyone can prune and cut back deciduous trees, conifers, vines, peach, plum, and apricot trees now.
Black Frost se voet
- What is it: Black frost happens when humidity is too low for frost to form, but the temperature drops so low that plant tissues freeze and die, becoming blackened.
- Where it affects: The leaves of plants are the most affected. Avoid pruning the burnt leaves as they will continue to protect the plant in case of another freeze invasion.
- How to protect: You can protect plants even more by using raised beds, mulching up (a lot), covering growing trees at night, and changing to mid-morning watering to allow all water to evaporate before evening temperatures drop.
- What to do: Once a plant has succumbed to the black frost horseman, do not prune or feed it, simply send it love – this too shall pass. Once the temperature increases, some plants will shed dead leaves on their own, while others that have died back will begin to regrow.
Inspirational edibles to plant: Rocket, cabbage (red and baby), horseradish, asparagus, global artichokes and rhubarb, lettuce, cauliflower, broccoli, spinach, beetroot, turnips, Brussel sprouts, oriental vegetables, celery, parsley, peas, and leeks. Pop into your fave GCA Garden Centre and see which seedlings are available.
Homegrown’s to harvest: Citrus and avocados (finally), leeks, Brussel sprouts (from the bottom upwards), carrots, parsnips, and cabbages.
Mulch-up your canvas: Mulch the entire garden with lovely autumn leaves to protect plants from the cold and assist in water retention in dry areas. Cape gardeners, get on top of those rain-loving winter weeds with max mulch power.
