Winter Wash for Apple Trees

Australian House and Garden. Deciduous fruit trees rest in winter and this is the perfect time to treat them with protective sprays and washes. Ever since the late 19th century, when Professor Pierre-Marie-Alexis Millardet discovered that copper can be used to destroy fungal spores on plants, gardeners have been using it in their gardens in winter.

Lime, too, controls pests and diseases and is used to treat garden plants. When the trees are bare and leafless in winter, copper and lime-based sprays can't burn foliage or damage blooms, but they can destroy spores that are lying in wait for warmer conditions. As the weather warms, spores begin to infest trees and shrubs with diseases such as brown rot and peach leaf curl.

The discovery of the copper-based fungicide, known as Bordeaux spray, by Professor Millardet of Bordeaux, saved the French wine industry at the time from the devastating effects of downy mildew.

Some of the most widely used agricultural fungicides contain copper, including copper oxychloride and copper hydroxide.

While these remain effective pesticides, copper oxychloride is now considered unsuitable for organic gardens. Follow in the Professor's steps and make your own organic Bordeaux spray, or buy a copper-based fungicide at the nursery.

By collecting spoiled fruit and raking up fallen leaves from around productive plants, you are removing spores. Don't use the fruit and leaves for mulching, as they remain a source of reinfection and reinfestation, although they can be hot composted.

If you haven't time to make a hot compost heap , where it will warm up to the 60 degrees Celcius necessary to kill spores and eggs, simply bury the lot in the garden. Bury the fruit half a metre deep in the soil, and place leaves in the bottom of a trench one spade deep where they can rot without spreading problems.

This not only improves the look of the plant, but removes areas that are easy targets for fungi and bacteria, and provide niches for pests to lay eggs. Make sure your pruning equipment is sharp, so wounds are clean and not ragged.

To prevent the spread of any bacterial and viral disease around a garden or orchard, sterilise pruning equipment in between pruning each tree or shrub. To do this, dip the blades in disinfectant for 30 seconds. Use tea-tree oil, which is expensive but effective, or Clensel, a commercial disinfectant. Alternatively, you can make up your own disinfectant with a mixture of one part household bleach to 99 parts water.

Never paint pruning wounds on trees. Wound preparations have been proven to cause more problems than they are alleged to cure. Pruning wounds will naturally heal and seal far better if left alone. A heavily laden 'Lemonade' tree hangs over the path. Many common pests and diseases are resting now, hiding unseen as eggs and spores lodged in bark and bark fissures. Reset the balance using a process known as 'winter washing', on all deciduous fruit trees and shrubs, from apples and figs to peaches and pomegranate.

This treatment is also applied to ornamental plants such as roses and frangipani that suffer fungal problems later in the year. Bordeaux spray and lime sulfur are commonly used winter washes. Both are very effective at controlling fungal spores along with the eggs of most pest insects and mites.

Yates Fungus Fighter is an organic-approved fungicidal spray based on cupric hydroxide, but isn't currently registered to control pest eggs. Although citrus are evergreen in winter, they also benefit from care at this time of the year. Established trees that have become infected with melanose disease or brown rot disease need special care.

First, remove old mulch and fallen fruit. Either hot-compost or bury this waste as it will be contaminated with disease. Apply fresh mulch around trees, making sure it doesn't touch the trunk. Apart from cooling the soil, controlling weeds and retaining moisture, a layer of clean mulch 5cm thick helps to break the cycle of infection. Fresh mulch reduces the risk of fungal spores in infected soil being splashed by rain or irrigation up onto healthy citrus leaves.

Any infected citrus trees with melanose disease or brown rot disease should then be winter washed with cupric hydroxide. Make sure all parts of the citrus trees are thoroughly soaked, especially leaf undersides, bark and bark fissures. If you have experienced trouble with stink bugs, such as bronze orange bugs or spined citrus bugs, winter is also the time to control these pests.

Spray trees twice in mid-winter using horticultural oil. The oil-based spray is particularly good at smothering the nymphal stages of the bugs, dramatically reducing the number that reach adulthood. In warm, dry regions, water citrus regularly, especially in windy weather, but don't feed them until after they finish flowering. Too much nitrogen encourages citrus to abort embryonic fruit, and the lush, leafy growth will only attract virus-transmitting aphids.

If you have a lot of plants to treat, making your own Bordeaux spray is economical. Here's how to do it. Do not use metal buckets as the mix reacts with metal. Stir well with a wooden or plastic spoon.

Thoroughly stir, then pour this mixture into the lime water, while stirring continuously. The Bordeaux sprayis ready to use immediately. Pour the mix into a sprayer. Wet all plant surfaces thoroughly, especially bark fissures.

Bordeaux spray and lime sulfur settles, so shake the sprayer every now and then. Wash off any spray that splashes onto turf, or other foliage, using fresh water.

Thoroughly clean out sprayers with warm soapy water, paying particular attention to nozzles. Bordeaux spray and lime sulfur burn leaves, which is why they must be applied during winter dormancy before flower buds or leaves open.

Fruit Tree Care: Spraying Dormant Oil

Call Us: Lines Closed Show sites now open. Snacking on a juicy piece of fruit plucked from the branch of a homegrown tree is something to feel really smug about!

You can prevent aphids using neem oil or essential oils around your plant, or opting for growing plants which will attract natural aphid.

Organic Insecticide: Winter Wash

Gardeners are not the only ones who enjoy fruit trees. Pests -- such as scales, aphids and mites -- feast on the tender plant parts and overwinter on the fruit trees. Dormant oils control these annoying pests and are safe for use on fruit trees. Homemade dormant oils provide the same benefits as commercial oils without the expensive price tag. Dormant oils once contained heavy oils that had to be applied when the fruit tree was in its dormant stage to prevent damage to buds and foliage. Nowadays newer dormant oils are lighter, allowing them to be applied at anytime during the year without harming buds. Because you can apply newer dormant oils throughout the season, the term "dormant" typically refers to the time at which the oil is applied. Dormant oil consists of refined petroleum oil that -- when applied to trees -- will smother overwintering insects -- such as aphids, scales and mites -- and their eggs or will dissolve their protective waxing coating. It is applied in the winter months when fruit trees are in their inactive period. For dormant oil to provide proper control, the oil must come in contact with the pests.

EVEN though autumn came late this year, the fruit garden has now finished for the year. There may an occasional rogue raspberry but nothing that could be deemed a late crop. I've therefore spent the past couple of weekends in the orchard, readying the apple trees for winter. All the fruit has been removed from the branches and stored in boxes alongside salvageable windfall. At this stage, my wife takes over, transforming this year's harvest into liqueurs, jellies and jams.

Title: Spraying Fruit-Trees, Etc. Author: L. If fruit-culture in New Zealand is to attain the important position amongst colonial industries that our genial climate and fertile soil entitle it to, then the growers must be prepared to vigorously fight the many insect and fungus pests which, unfortunately, in most instances have been imported with the various fruits, and which in several instances, at least, while doing but little injury in more rigorous climes, have here increased with such wonderful rapidity as to become most serious factors in the success or otherwise of fruit-culture.

Growing fruit trees can be a rewarding, as well as delicious, practice, but keeping those fruit trees healthy can become expensive if you need to buy fungicidal sprays, pest sprays, and other fruit tree sprays. Making your own homemade spray for fruit trees is not difficult and does not require a lot of ingredients. Homemade fruit tree sprays are often less toxic and just as effective as the sprays you can buy in the store. Prevention is the best method for dealing with fruit tree diseases, and a homemade compost tea is one of the best preventive methods for fruit trees. Make your own compost tea using compost from your garden in a ratio of about 1 cup of solid compost matter to 1 gallon of water.

One effective method of protecting fruit trees from overwintering pests and their eggs is spraying dormant oil in late winter or early spring.

Hiding within trees is one of the most common survival tactics these pests have. They do this to survive, but they can also cause serious harm to your trees and plants if you allow them to nest unchallenged. Here are a few examples of the common pests your trees might face this winter. One insect you have to worry about in winter are red spider mites. They can attack all sorts of plants but they are generally associated with apple trees. These little pests are very active in the spring and fall.
