Autumn is right on time this year with cooler, shorter days and trees showing off their autumn jackets in hues of gold, red, copper and umber. Winter is coming, and it’s time to prepare and protect the garden and gradually move inside to cozy up and enjoy the magic of May!
The vibrant shades of Autumn
Planting
Lily bulbs will land on the shelves this month. Plant them as soon as they are available. Trim the flower stalks on old Liliums to ground level.
Continue planting spring-flowering bulbs. Water bulbs deeply and ensure they never dry out completely. Feed fortnightly with bulb food or an organic 3:1:5 fertiliser. Keep feeding fading bulbs to boost them for next season.
Dead-head winter-flowering annuals to encourage further flowers. Continue planting winter-flowering seedlings like Pansies, Violas, Poppies, Primulas, Calendula, Stocks, Sweet Peas, Cineraria, Primulas and Primroses. Feed fortnightly with seedling food or liquid fertiliser. Mulch well.
May is the perfect month for planting roses. Come spring, they will be settled, and you will be rewarded with strong growth and lovely blooms. Choose your favourite from our incredibly wide variety of roses.
Plant and transplant trees, vines, shrubs and hedging plants now.
Sunbird feeding from aloe flowers
Aloes will add warmth and vibrancy to your winter garden, plus they’re waterwise and very easy to maintain. Aloe flowers are a favourite with nectar feeding birds and provide a vital source of energy during the winter months. Visit us and choose from our wide range of aloes, just waiting to be planted into your beds, rockeries and pots.
In the Vegetable Garden
Remove the last of the spent summer veg and plant Swiss chard, leeks, brassicas, peas, winter lettuce and oriental greens.
Thin out seedlings of seeds that were sown in situ if needed and feed all seedlings with seedling food or a water-soluble fertiliser. Mulch well to keep their little roots warm.
May is a good time to lift, divide and replant perennial vegetables and herbs like lemongrass, chives and artichokes.
Prepare beds in full sun for asparagus corms, which will arrive on our shelves later in May.
Feed vegetables with an organic 8:1:5 or 6:3:4 fertiliser.
Calendula make for great companion plants
Cabbages are prone to aphids. Spray preventatively with an organic aphicide. Interplant with sage to deter white fly and Calendula, pennyroyal or chives to repel aphids.
Keep an eye open for signs of cutworm around young vegetable seedlings and place bait if necessary.
Vegetables: Broad Beans, Onions, Peas, Chinese Cabbage, Winter Lettuce, Mustard, Oriental Greens, Radish, Swiss Chard and Parsnips
Herbs: Rocket and Coriander
Although it is too late to sow many flowers, herbs and vegetables at this time of year, hardened-off winter seedlings are available in the nursery to be planted now.
A few more things to do in May…
Change the settings on your irrigation system to suit the temperature and rainfall for autumn.
Deadhead rose bushes and spray fortnightly with a fungicide to combat black spot.
The average first date for heavy frost in Gauteng is the 19th of May, so stock up on frost protection fleece in advance to protect tender plants. Move sensitive potted plants to a protected spot.
Water the garden early in the day and mulch generously around all plants to protect roots. Always leave some space around the stems of plants when mulching to prevent disease. Feed with an organic 3:1:5 fertiliser to strengthen cell walls and control evaporation.
Beautiful Azalea blooms
Spread a layer of acid compost around Camellias and Azaleas and keep them moist to prevent bud drop. GREAT NEWS: All Azaleas are on a 20% OFF promotion for the month of May – while stocks last…
Mow lawns on a high setting and water if dry. Do a last overseeding with evergreen, cold tolerant lawn seed where needed.
Collect all the fallen autumn leaves and use as a mulch or add to the compost heap. Alternatively collect leaves in black plastic bags and leave to decompose into wonderful leaf mold. Mind that you don’t use diseased leaves though.
LIGHT BULB MOMENT: Draw a rough plan of your garden and mark the position of plants like Echinacea, Hosta, Alstroemeria and all bulbs, like Eucomis, that will die back in winter. This way, you or your gardener will know exactly where not to dig and plant to prevent damage and overplanting.
Indoor Plants
As days cool down, indoor plants will need less watering and can very easily become waterlogged. Keep an eye on them and allow the surface soil to dry out slightly before watering again. Do the finger test: stick your finger in the soil up to the first joint and if it feels moist, wait a bit longer with watering.
Bring colour indoors with flowering indoor plants like Cyclamen, Chrysanthemum and beautiful Phalaenopsis and Cymbidium orchids.
Hyacinth bulbs can also still be planted in pots on a bright windowsill from where they will lend fragrance to any room.
Feed once a month with a liquid plant food for indoor plants. Feed orchids in flower with a specially formulated orchid food.
For Goodness Sake
Feed the birds more regularly as their natural food sources start to run low. Include suet in your feeding programme to provide them with a source of fat and energy.
Invest in plants like Wild Dagga and Aloes for nectar-feeding birds and ornamental or wild grasses for seed-feeders.
Don’t neglect cleaning birdbaths as birds still enjoy a good splash on the warmer days!
Bird enjoying a healthy snack
Last, but most certainly not the least, Sunday, the 11th of May, is Mother’s Day. Spoil the mom in your life with a specially wrapped gift plant, fresh flowers, a favourite rose, something from our décor section, or a Lifestyle gift voucher. Happy Mother’s Day to all the moms out there!
