As winter starts to settle into the garden, you might be thinking about putting on your slippers, not your gardening boots. But your garden still needs lots of love during the quieter months, and June is the perfect time for planting roses, citrus, and winter veggies, as well as preventing pesky lawn weeds. And don’t forget your pruning tools – some solid pruning now means you can look forward to beautiful blooms later in the year.
- Trees and shrubs: Camellia sasanqua, camellia japonica, correa, crowea, daphne, flowering apricot, French lavender, Geraldton wax, grevillea, hebe, poinsettia.
- Annuals and perennials: Begonia, marigold, hellebore, kalanchoe, pansy, polyanthus, strelitzia, violets, orange trumpet vine.
- Bulbs: cyclamen, jonquil, narcissus.
- If you think winter equals no flowers, think again. Cineraria, hollyhock, pansy, stock, alyssum and herbaceous perennials such as delphinium, Russell lupin, tuberose and gerbera are in full bloom.
- It’s also a great time to plant your favourite roses, fruit and citrus trees and deciduous trees and shrubs.
- Winter is all about hearty vegies like broad beans, rhubarb, beetroot and spinach.
- Cut back and divide your perennials. Replant the divisions immediately and keep damp until established.
- Give your annuals and vegies liquid fertiliser
- Cut back deciduous trees while there are no leaves.
- Trim hydrangea stems bearing dead heads and remove old dead wood. Make sure to cut back to the first or second pair of buds to ensure flowers return next season.
- Pare down rose stems.
- Slugs and snails are on the hunt for emerging bulbs and seedlings. Use animal-friendly pellets like Multiguard Snail & Slug Killer as per packet instructions.
- Watch out for caterpillars on cabbage seedlings. Spray with Dipel or sprinkle with Yates Tomato & Vegetable Dust.
- Check cineraria for leaf miner. If infected, spray with Success ULTRA.
- If you notice little white freckles on your citrus or rose plants, it may be louse scale. Treat with lime sulphur.
- Now’s the time to ward off nasty winter grass. This weed seeds in autumn, winter and spring, then dies off in summer heat. Left untreated, it’ll weaken your lawn and result in more winter grass next season. As soon as you notice winter grass, spray with a selective weed control like Amgrow Winter Grass Killer.
General garden care
- Take advantage of the quieter months to service, clean and sharpen your gardening tools and lawn mower.
- Buy and plant spring flowering perennials. Add a handful of compost, manure or some complete plant food to the soil. This will ensure healthy spring growth.
- Cut back and divide your perennials. Simply remove the plant from the ground and shake away some of the soil so that the roots are easily seen. The root ball can now be divided by pulling it apart with your hands, a spade or sharp knife. Replant the divisions immediately and keep damp until the new plants are established.
- Reduce the amount of water you're giving to your indoor plants over winter. Don't forget, most indoor plants are native to tropical climates (where thick canopies block direct sunlight), so bring the water to room temperature before you give them a treat - they're not used to it being icy!
- PestOil to control aphids on young annual shoots
- Moss and algae killer to stop paths and paving getting slippery
- Orchid potting mix to re-pot moth orchids
- Deciduous trees and climbers
- Camellias are in full bloom making selection a little easier - but it's always hard to choose between these beauties!
