Be a winter-winner, get your May maintenance in check, sow cool-season seeds, and grow with the flow as we enter our last month of autumn. We’re celebrating our adaptable green fingers by also highlighting Africa Month and all our glorious ingenuous glory. The party doesn’t stop there – say hello to Phlebodium, the perfect indoor plant baby to gift to the woman you adore this Mother’s day!
Crispy blooms to plant
Bulb up: Honour our African heritage with a jive of colour from Sparaxis (Harlequin Flower), genus Ixia, and Tritonia. Try also these perennial bulbous plants: Sweet garlic (Tulbaghia fragrans), Weeping anthericum (Chlorophytum saundersiae), Red-hot poker (Kniphofia praecox).
Bush out: Pork bush (Portulacaria afra) is a lekker local hero hedge. Good as a barrier plant, tolerates frequent pruning, extremely drought-resistant, and fast-growing.
Succ in: Aloes are in full swing, oh yhea! Try Peri-Peri, Sea Urchin, and Porcupine.
The 4 P’s: Plant with the 4 P’s - poppies, pansies, petunias and primulas.
Rose bed revival: Long-stemmed roses can be picked now. If the plants are in full leaf, continue with your spraying programme but reduce watering. Plant winter-flowering annuals like pansies, poppies, or compact snapdragons, around rose bed edges to give them a revived burst of colour (and hide bare branches).
Split & divide: If the following perennials have stopped flowering, they’re ready for the operating table: Japanese Anemones (Anemone japonica) and Obedient plant (Physostegia virginiana).
Be wise, fertilise: Annual stocks and larkspurs benefit from extra nitrogen to promote good growth and flowering throughout winter. Consult your GCA Garden Centre expert for advice on liquid fertilisers.
Eye candy: Add rows of ornamental kale between other winter vegetables. Companion plants include beetroot, violas and pansies (both have edible flowers), onions, nasturtiums, and spinach. Ornamental kale makes an unusual but stunning winter option for colour.
Mixed masala: Interplant leafy winter veggies and root crops with herbs like lavender, thyme, oregano, parsley, yarrow, and comfrey.
Cuppa’ your own Joe: The coffee plant (Coffea arabica), which is actually a TREE, will earn you kudos from coffee snobs if you can manage to grow it successfully in a high-light indoor area. Imagine grinding home-grown beans? Count us in!
Un-gogga your cabbage: Pull up old sweet basil plants, chop them up, and then use them as a natural insect repellent mulch around your cabbages – fancy, na?
If it’s yellow, it ain’t mellow: Prevent disease by removing all yellow leaves from brassicas such as Brussel sprouts, cabbages, cauliflower, and broccoli.
Fruitful advice: Feed avocado trees with 3:1:5 and mulch ‘em up. Plant litchis and citrus, while also keeping mango trees dry before their flowering starts. In coastal and lowveld areas, feed with a nitrogen and potassium combination fertiliser. Seek advice from your local GCA Garden Centre.
Prevent pests: Prevention is better than cure! Remember that good soil + good drainage + mulch + fertilising/feeding = a healthy plant.
Spray the eco-way: Keep spraying those conifers with a nutritious organic insecticide.
Rake it, baby: Rake fallen leaves off the lawn to prevent them from blocking out sunlight, and then pop them on the compost heap. Coastal gardeners can still apply one more dose of fertiliser before winter sets in.
Freeze alert: Watering should be done after nine in the morning and completed by three in the afternoon – wet plants will freeze, haai shame!
Plant low-growing grass, increase indigenous bed sizes, add stepping stones or bark shards – here are some ideas for a no-mow lawn.
