Winter can be a challenge, but it sure puts a rosy hue in your cheeks when you rug up, brave the elements and go about doing some of those winter gardening tasks which have been beckoning from outside. Enjoy a warm drink – and the satisfaction – when you come inside.
What’s exciting about this time of year is that the nursery now has a full range of deciduous trees, both ornamental and fruiting, grape vines, berry canes and roses. Every year we expand our range and this year we have new varieties of dwarf fruit trees added into our long list of varieties. Now is the best time to plant these guys as they are dormant or ‘asleep’. When these plants are having their winter rest, they are very robust and easy to handle. Transplant shock is minimised and don’t worry that they look like sticks now because boy, will they take off in spring. Our bare root stock are potted to ensure the new roots don’t have the chance to dry out, to maximise success once planted in your garden, but they are still available at very reasonable prices. If you need some help selecting a tree or rose, come in and ask our expert nursery staff for advice. We have a fact sheet on planting bare root stock.
We have a huge range of fruit trees to choose from including almonds, walnuts, peaches, pears, apples, cherries, nectarines, persimmons, plums and pomegranates. Don’t forget to prune your fruit tree as you plant it (or ask us to prune it for you before you leave the nursery). This is very important as it ensures the tree will transplant well and develop a strong branching structure. Those with small gardens can try dwarf fruit trees, such as Ballerina apples, nectarines, peaches and peaches or espalier an apple or citrus tree to create structure and maximise sunlight to your garden. Also fun to try are berries -try a currant or blueberry bush (very decorative as well as delicious!) or decorate your fences and pergolas with grape vines, kiwi fruits, passionfruit or loganberries. In addition to trees, shrubs and vines, don’t forget the subterranean wonders of the season such as rhubarb, asparagus, certified seed potatoes and shallots. All are now available in the shop and the produce area and it’s exciting to watch the emergence of these in early spring.
The nursery also has a variety of cool season vegies and herbs in stock. Plant broccoli, cabbages, leeks and cauliflowers to make warming winter soups. Many of the Asian-style, green, leafy vegies are better grown through the cooler season as they don’t bolt to seed -just pick them as you need them. Remember to dig in plentiful amounts of cow manure and mushroom compost to feed these hungry plants quickly.
Asparagus and rhubarb are grown now from bare-root crowns in rich, well drained and composted soil. If they are planted in a sunny part of the garden and can be left undisturbed, you are in for a delicious crop year after year. They are both well-suited to surviving drought conditions. Lettuces can still be planted now along with vegie seedlings of beetroot, broccoli, carrots, chives, radish, silverbeet, snow peas, onions and cabbage. Plant your coriander now and it won’t bolt as it does when warmer. Broadbeans can be grown right through winter as can peas. There are both low-growing and taller growing varieties available. The taller ones will need staking.
Potatoes have a different taste and texture altogether when dug freshly out of the ground. Choose a variety you like and then grow your own. It is best to use seed potatoes as they are certified disease free. They love fertile soils and lots of tucker and as long as the soil is kept mounded around the growing mass of foliage, more and more potatoes will be harvested.
Keep an eye out for drainage problems in the garden. This is evident if water pools on the surface after rain or the ground stays soggy and muddy well after surrounding areas have dried off. Use gypsum or clay breaking liquid to break up clay soils. Adding compost and organic matter will also improve drainage. These spots may be ideal for plants that are suited to waterlogged areas or experiment with surface contouring. If you are concerned about drainage, creating mounded beds can solve a lot of problems.
Fuchsias, hibiscus, luculia, gardenias and other tender plants may need protection from the frost. There are several ways to protect plants from frost including covering plants at night, using frost protectants and watering the foliage. Some vegetables may also suffer from frost damage if they are flowering at the time, such as potatoes and peas.
July is the perfect time to prune roses and most deciduous trees including stone and pome fruit trees. Do not prune your apricot tree now nor any spring flowering trees and shrubs yet, wait until after they have flowered. This includes some roses which flower only once, such as the Banksia roses. Tidy herbaceous plants by cutting back dead and dying foliage flowers and stems. Lift and divide established perennials.
To protect soft new growth after cutting back perennials, cover them lightly with pea straw or lucerne to prevent frost damage.
Spraying copper sulphate on the bare stems after pruning can help prevent fungal disease.
Prune deciduous clematis back to a pair of plump buds approximately 60 cm from the ground and remove any weak shoots altogether.
Fruit Tree Pruning
Keep in mind that fruit trees in home gardens are often intended to be ornamental as well as fruitful, so this will help determine the shape you would like your tree to have. If it is strictly for the fruit, then read on.
Pruning sweet cherries, European and Japanese plums, apricots
Prune to an open vase shape in the young tree to develop its shape. No annual winter pruning is then required after the first three years, except to remove dead or diseased wood, or branches crossing over one another and rubbing. Apricots are best left in winter and pruned in early autumn, to reduce the risk of fungal disease entry.
Remove a third to a half of the previous year’s growth, including any internally growing branches and thinning out any weak side-shoots.
These can develop very well with only a little pruning to remove weak growth. It’s important that an open-centred vase shape is promoted to allow for maximum sunlight penetration into the centre, so prune out any internal, inward-growing branches. Shorten sideshoots to leave 3 to 4 buds. If there are any vigorous side branches, tie them to keep them horizontal as this will force them to become fruit-bearing wood.
Helpful pruning info:
This is a fungal disease that infects peaches, nectarines, almonds and other Prunus species. The symptoms are noticed in spring and summer, when the leaves appear with raised lumpy light green and red patches and are curled up. This problem weakens the tree if it occurs year after year, and will result in a reduced fruit yield. Once you see the symptoms, it is too late to spray. The trees should be sprayed from mid to late winter from bud swell, until the leaves emerge. Spray with copper sprays such as copper oxychloride during this period. This is a preventative spray, so the swelling buds need to be covered with the copper spray. Once the buds have burst open, it is too late to spray. The nursery puts up signs when we spray our peaches, nectarines and almonds to remind you when to spray your own trees at home.
Kids in the Garden
Make a living teepee! Bind together up to 5 bamboo stakes with string, spread out the base and place it firmly in some soil in your garden. Tie more string at different intervals between the stakes for the plants to grow along. Plant snow-pea seedlings at the base of each bamboo stake and as they grow, gently train them along the string. Soon you’ll have a living teepee that you can eat off!
