How to Grow & Prune Your Own Raspberries in Summer [2022]


Raspberries, which may range in flavor from sweet to tart, are a popular dessert item throughout the summers. However, if you cultivate your own, there is no need to pay the costs in the grocery. Raspberries have a high resistance to disease and may be grown with very little attention once they have been planted.

There are several varieties of raspberries, the most common of which are summer-bearers, which only produce a single crop, and ever-bearers, which produce a harvest in the summer and a second, lighter flush of berries in the autumn. Summer-bearers and ever-bearers both yield a crop of raspberries. Raspberries may be found in a variety of colors, including red, yellow, gold, black, and purple.

Raspberries — Not the Same as Blackberries

Blackberries and black raspberries are not the same thing. Unripe blackberries have a color that ranges from greenish-red to scarlet, but as they mature, they take on a more purple-black appearance. The subspecies or type of raspberry that you’ve planted will determine the color of the fruit as it matures.

Taking a glance at the torus, also known as the center of the fruit, is the quickest and simplest method to differentiate between blackberries and raspberries. When blackberries are picked, the tender, white center of the berry remains intact inside the fruit (this is termed “picks with”). Raspberries, on the other hand, get detached from the torus, creating a cavity or hole in the centre of the berry while the core remains attached to the terminal end of the stem.

How to Grow Raspberries

The majority of the United States is within the range of USDA zones 4-7, which is suitable for growing raspberries. Because canes can yield fruit for many years, you will want to make sure the soil is in good condition. Make sure there is enough drainage and work in a lot of organic matter as you dig it in. Add sand to your soil in order to increase drainage if it contains a lot of clay. Raspberries thrive on soil with a pH about 6.0. The addition of acidic organic matter, such as compost, well-rotted manure, chopped oak leaves, or a little amount of sulfur, should be done if the pH of your soil is over 7.0, which indicates that it is on the more alkaline side. If the pH of the soil is too low, which indicates that it is acidic, a tiny quantity of lime or wood ash may be added. However, take care not to apply an excessive amount since just a little bit may go a very long way.

Raspberries need a lot of light and may easily develop mold or mildew if they are planted in a confined space; thus, it is important to provide them a lot of space to grow in. While red and golden raspberries love to climb on a fence or trellis to support their growth, purple and black raspberries do best when planted in a densely wooded area. In zone 7, raspberries perform best when they get midday shade, even if it’s only a little bit.

Early in the spring, about four to six weeks before the final day on which frost is forecasted to occur, canes or bare roots should be planted in the ground. Canes should be planted in soil that is somewhat deeper than the soil in the container they came in at the nursery. If you want to cultivate raspberries in pots, you must wait until the danger of frost has gone before moving the plants outdoors.

Canes should be fertilized with organic fertilizer in the late winter months. Applying mulch in the spring, such as sawdust, bark, or straw, can help maintain a pH that is more stable and will prevent weeds from growing.

Pruning Raspberries

In the late summer, clip fresh canes to a height of four or five feet to stimulate the growth of additional plants that yield berries. This will promote the development of lateral branches, which will result in an increase in the number of buds and, therefore, the number of berries produced during the subsequent growing season.

Canes that are no longer living should have their tops lopped off so there is more space. Canes that are three years old should also be pruned, since they produce poor fruit and will perish by the next season anyhow. Pruning is an effective method for preventing damage from cane borer larvae, despite the fact that raspberries are seldom affected by pests. If you see that individual raspberry canes are becoming weak, prune them so that they are six inches shorter than the damaged area. Burning the wilted cane at a location that is not close to the raspberry patch can ensure that the larvae do not return to infect your plants.

Growing Raspberries in Containers

The ideal container for raspberry canes is one that is deep, broad, and has adequate drainage. This is because raspberry canes prefer to proliferate via runners. A wine keg or the bottom half of a whiskey barrel that has been perforated with holes would serve this purpose well. This method is most successful in regions that do not experience severe freezing temperatures throughout the winter.

To prevent the soil from escaping the container, line the bottom with a weed barrier or burlap, and then fill the container about three-quarters of the way with a combination of potting soil and garden soil with an approximate ratio of 80% potting soil and 20% garden soil. Make sure the hole you dig is big enough so that you can lay your plants somewhat deeper than they are in the pots they came in at the nursery and give their roots room to stretch out.

It is possible that container-grown raspberries will need more water than those grown in the ground; thus, it is important to ensure that they get water on a consistent basis, particularly while the fruit is growing. Bigger containers are preferable to smaller ones throughout the summer since you will be able to provide more thorough but less frequent irrigation for the plants in the larger container. In addition, an all-purpose fertilizer should be applied to the canes in the early spring, and they should be pruned as necessary.

Benefits of Raspberries

Raspberries include a high concentration of antioxidants and anti-inflammatory substances, both of which may reduce the risk of developing cancer and help relieve pain. Research is being done on a substance known as raspberry ketone because preliminary findings suggest that it boosts enzyme activity and metabolism, which might be beneficial for those who are battling obesity and type II diabetes (the jury is still out on this one, though).

In addition, one cup of raspberries provide half of the daily value for vitamin C that is suggested for an adult, in addition to fiber and other essential elements. Why not give growing a few raspberry plants in your own home garden a go, considering how beneficial they are to your health and how easy they are to cultivate?
