Weed controlĪll perennial weeds, such as quackgrass, Canada thistle and bindweed should be destroyed the year before planting. If possible, start preparation 1 year before planting.
Since plantings can remain productive for several years, special care must be taken to prepare the soil before planting. In more northerly areas, planting in areas that are protected from winds may reduce cane breakage and winter injury.Īlso avoid low-lying areas that may be poorly drained and prone to frost damage. There may be root diseases present that can infect raspberries and blackberries. Gravelly soils can be improved by adding organic matter, but extra water and fertilizer will be needed for good yields.Īvoid planting in areas where eggplant, potatoes, tomatoes or strawberries have been grown. They are usually poorly drained, and good drainage is absolutely essential, as roots will die in wet soil. Choose a sunny site that is well drained with a deep, sandy loam soil with plenty of organic matter. Good location and soil type are important for the successful growing of raspberries and blackberries. Purple and black raspberries do not produce suckers, so shoots occur in groups or “hills” instead of being scattered throughout the row. Red raspberries and blackberries produce shoots or “suckers” from both places and will usually fill in a row very quickly. Shoots may arise from 2 places: from buds at the base of the old canes and from buds on roots. In the second year, it produces fruit and dies soon afterwards. During the first year, a shoot reaches its maximum height (and is called a “cane”). The root system of raspberries and blackberries is perennial, but each shoot is biennial - it only survives for 2 years.

Raspberry plantings can remain productive for several years. Raspberries (Figure 1) and blackberries (Figure 2) are excellent fresh, frozen or canned or made into jam, jelly or juice. Blackberries are not winter-hardy and should be grown only in those areas with mild winters or where protection for the canes is possible. There are many red raspberry cultivars that are winter-hardy enough to withstand winter in most parts of Ontario. everbearing (or primocane fruiting) cultivars that produce a second crop in the late summer and early fall.normal cultivars that produce a single crop in early summer.The canes of red raspberries grow upright, while black raspberry and blackberry canes are long and trailing.
Blackberries may also be available, but differ from raspberries in that the “core” stays in the fruit when it is picked. There are three kinds of raspberries available to the home gardener: red, purple and black.
