All that glitters is gold, yellow, orange, and red!
Let’s celebrate Nelson Mandela Day on 18 Julyin style by showcasing – the gorgeous, golden-yellow Strelitzia, appropriately named after Madiba as ‘Mandela’s Gold’. It flowers beautifully this time of year and is an amazing feature plant. Also, Aloes are out with striking spears of yellow, orange and red, adding some much-needed warmth to our gardens and patios during these cool July days.
The global lockdown was indeed a rather scary experience, but it also presented a golden lining with some much needed time for humanity to reflect on our impact on the natural word. How chilling it was to observe the rapid decrease in air pollution, the abundant return of many animals to urban areas, and the increase in sea-life activity around the world. Hopefully, this will help us all to deepen our appreciation of Mother Nature and whole-heartedly celebrate the International Day of the Conservation of Mangrove Ecosystems on 26 July, and World Nature Conservation Day on 28 July.
Trending – Life is a garden with water-wise Aloes
Gone are the days that Aloes were only seen on road trips as large shrubs growing on mountain slopes. We have a huge variety of spectacular Aloes bred for our patio pots and gardens. Breathe warmth into your winter garden and attract sunbirds and bees at the same time. Aloes range from dwarf forms like ‘Peri Peri’ and ‘Hedgehog’ to the multi-coloured ‘Charles’ and ‘Ballerina’, the rich colours of ‘Fireball’, ‘Andy’s Yellow’, ‘Gold Sparkle’ and many more. These sculptural plants have interesting leaf shapes and colours such as ‘Freckles’, which has grey tones and speckles, and Aloe striata, which has stunning pink-lined flat, grey leaves. Treat yourself by visiting your local GCA Garden Centre and choosing one that blows your hair back.
Best veggies to grow in the winter
It may be a bit late to make a start on some of these veggies right now, but you can always plan for next winter too:
TIP: Add some vibrant colour to the veggie garden by using Swiss chard Bright Lights which has brightly coloured stems.
TIP: Remember that by sowing a little extra seed when doing your regular veggie seed sowing you can also keep a little patch aside for Microgreens.
TIP: It’s time for thyme – yes, this herb likes the cool winter months and is a wonderful pairing with most of the winter veg. Again, grow in a pot or add to a mixed container if you are short of garden space.
If your Aloes have small grey ridges or bumps forming on the leaves it probably indicates an infestation of scale insects. Take a picture or a sample into your local GCA Garden Centre and allow them to recommend a spray that will not burn the tender, succulent Aloe leaves. For scale insects on other plants spray with a recommended organic spray dilution.
TIP: Avoid spraying the soft, new leaves of ferns and tree ferns with as some sprays can damage them.
Life is a garden – so let’s get on with life and prune our roses now in July before their buds start swelling. Buds swell in early to mid-July in the Lowveld and at the coast, and during August in the Highveld. Pruning is a labour of love from you to your roses and will give them the vooma they need for strong, healthy new growth and reduce the number of flowering stems, resulting in an increase in flower size for the coming season.
Shopping list: For best results, here is the equipment required:
Ode to the edible pansy: Pansy flowers can freeze completely at this time of year due to the frost and then as the sun thaws them out in the morning, they defrost and smile up at you, hence the Afrikaans name “gesiggies”.
Both pansies and the smaller Viola, from which the pansies originate, produce adorable flowers that are hard to resist. They produce masses of charming flowers over a long period, making them the most popular choice for sunny spots in the winter garden, in pots, or even hanging baskets on the patio. If planted late in winter it is advisable to plant them in semi-shade to protect them from the harsher spring sun. Both pansies (Viola x wittrockiana), Violas (Viola cornuta) and Viola tricolour “heartsease” make for the prettiest edible flowers for decorating pastries, garnishing cocktails, soups, and even lemonade. Violas are a more delicate garnish while the pansy flowers crystallise very well and can also be eaten as sweets or used to decorate ice-cream.
Pansy’s claim to fame: Their name in French, “Pensee”, means loving thought, and if a lover was near (and a bouquet of pansies was as well) the lovers could communicate without talking.
Edible Calendulas: Calendulas flowers can be eaten whole, however, the petals are the tastiest part of the flower, with the white section that joins to the flower base removed. Their colourful petals lift the colour and mood of a salad, while their spicy flavour is used to garnish and season curries and soups.
Edible flowers are great fun to use as garnish and you may already have plants in the garden that you did not know have edible flowers.

Winter/Spring flower power
The power of colourful flowers is undeniable. Primulas, poppies, Calendulas, pansies, Violas, Dianthus, Alyssum and Petunias love the warm, dry Highveld winter weather. They should be in full flower in your garden right now, that is, if you planted them in Autumn. If not, they are all still available in seedling trays and possibly colour bags/pots to be planted in a sunny part of the garden, patio pots or hanging baskets. You’ve got the flower power waiting at your local GCA Garden Centre.
TIP: Keep up the watering and regular fertilizing of your flowering and veggie annuals.
Winter/Spring flowering shrubs
Camellias and azaleas, sometimes labelled with their botanical name Rhododendrons, are both spring flowering, acid-loving plants. They will benefit from mulching with acid-compost and most importantly, be sure to water them consistently, as opposed to constantly, until and through flowering. If you do, you will prevent bud drop in the Camellias and the buds browning off and not opening in Azaleas.
Tip: Special acid-loving food is available for both the Camellias and azaleas but should not be used during flowering.
How is your garden’s bone structure?
Prune, projects, plan and take the plunge (the 4P’s).
July is a great time in the garden to be doing projects that you don’t get time to do during the rest of the year. It is also a good time to assess the garden’s “bone” structure. The natural architecture is pronounced in the colder regions where frost-sensitive plants are covered, roses pruned and deciduous trees and shrubs lay bare in the garden. The revealed cone structure of your garden allows you to assess the projects necessary to fix shortcomings and make exciting new changes to the garden. This can include pruning back tree branches to open the view or because they are shading over other plants. It also could include a variety of hard landscaping projects, for example, creating a new stepping-stone pathway to a secluded seating area.
Put on those gumboots, take the plunge and spend some precious time with your cute goldfish doing pond maintenance. Clean the pond, the filter, re-pot water plants and make sure to skim any potential leaves from blocking the filter and pump manually or with a surface skimmer.
TIP: July is an ideal time to plan your spring planting and summer garden.
Be water-wise and use the fallen autumn leaves to mulch your beds. This not only saves on dustbin space but is great for conserving moisture and warmth in the soil.
What’s in a name anyway?
The Cypress Aphid, Conifer Aphid or the Italian Aphid all describe the same aphid that has done considerable damage to conifers in South Africa over the last 30 years. They infest and actively attack certain conifer varieties in the autumn and winter months.
Identify: To check your conifers, open the foliage with both hands and look closely at the young stems. The aphid is larger than others but camouflaged since it looks just like the bark and will not move unless disturbed.
Treat: If your plants are infested, ask your local GCA Garden Centre for the recommended spray or drench and continue applying until the end of August.
Lowveld and in warm frost-free coastal regions
Short back and sides:Prune back and tidy up many of the garden shrubs and climbers before they put on new spring growth.
Sow: Asparagus, peppers, beetroot, carrots, cucumber, brinjal, globe artichoke, melons, Swiss chard, tomato, marrows.
Indoor living decor: Make sure that the indoor plant leaves are dust-free and open the windows and doors in the warmth of the day – stale air encourages pests and diseases.
Bird buddies: Clean birdbaths and fill with fresh water. Clean and fill bird feeders. Put nesting logs up for the new breeding season.
Western Cape, winter rainfall regions
Sow: Asparagus, beetroot, broad beans, Brussels sprouts, cabbage, carrots, cauliflower, leek, lettuce, onion, parsley, parsnip, radish, spinach and turnip.
