Now it's just a case of making sense of this mess. All I do is find that cane, go all the way to the base and then snip it off at ground level.īlackberries are usually dreadful weeds in Australia but nowadays there are sterile cultivars that aren't an environmental threat and they're also thornless, which makes them much easier to prune. These can be easily identified by the spent flowers and fruit heads.
They fruit on second-year wood so you need to take out the canes that have already borne fruit. You can prune these any time after they finish fruiting. However, autumn and winter are a great time to be doing maintenance to ensure good crops next season.
Use chemical control: Regular doses of a fungicide, especially in the spring, can stop an outbreak before it begins.TINO CARNEVALE: Being Tasmanian, summer, to me, means sweet, juicy berries and currants. Follow spacing guidelines when planting and avoid natural windbreaks for good air circulation. Grow plants in an open, sunny locations so the foliage dries quickly. Adding a layer of mulch to the soil will also reduce splashing. 
Control these factors by only watering infected plants when the top few inches of soil are dry, and by watering at soil level to reduce splashback.
Water carefully: Fungal diseases spread when plants stay in moist conditions and when water droplets splash contaminated soil on plant leaves. Rake and discard fallen leaves in the fall. Remove infected plant debris: Fungi can overwinter in contaminated plant debris, so remove all fallen leaves from infected plants as soon as possible. Purchase resistant varieties: Invest in fungus-resistant plant varieties to reduce the chances for black spot diseases. Here are a few tips to prevent black spot outbreaks.
