Container gardening with raspberries

Growing raspberries in containers is a great option for people with poor garden soil, shady backyards, or very little garden space. The great thing about gardening with raspberries is that you can put the pots in any sunny corner without worrying about the soil.

Which raspberry varieties grow well in containers? In theory, any berry bush you can plant in the back yard can grow in a container. However, shorter, more compact plants that stand upright without support are easier to work with.

If you want to get comfortable, check your local gardening store for raspberry plants labeled as "ideal for containers". Unless you want to put in an extra effort, choose a strain that will grab your attention.

You can grow both summer fruiting berry bushes and autumn fruiting varieties in pots. The former ripen from June to August and need support, the latter between August and October and grow upright.

When you start growing raspberries in containers, you'll want to choose a container that is at least 61 cm in diameter. If the container isn't big enough, the plants likely won't thrive. Also, their winter hardiness decreases and the plants can be killed by cool weather that will not affect canes planted in larger pots.

Learning how to plant raspberries in pots is not difficult. Fill your pot with a soil-based compost to help stabilize the plant. The mix “John Innes No. 3 “is well suited for this. Then position six sticks around the container and push the compost around them. Pour them in well.

The most important part of caring for raspberry containers is regular watering. You need to make sure that the soil / compost mixture never gets bone dry.

Caring for raspberry containers also includes feeding your plants. Dose them with a high potash fertilizer according to the directions on the label. This will encourage plenty of fruit to grow.

Both types are suitable for container gardening. Varieties such as "Boyne" and "New Washington" can be grown in Mediterranean climates such as US Department of Agriculture Zones 8 and 9.

Plant a single raspberry stick in a container 15 inches in diameter and at least 24 inches deep. Raspberry plants need well-drained soil. Therefore, place the container on bricks or wooden blocks to increase drainage. If necessary, punch or drill additional holes in the bottom of the pot to ensure the plant is adequately drained.

Raspberries are vigorous growers and make runners that will fill a bed. Pick a spot in full sun (where the plant will be exposed to at least six hours of direct sunlight a day) and dig well-drained soil in some compost to give them a go-ahead. You can buy raspberries bare-rooted in spring or as container plants for spring, summer, or fall planting. Regardless, plant the canes (branches) 20 inches apart and rows 5 feet apart. The sticks fill up every available space, and all you have to do is dig out those that venture in their path. Raspberry plants are hardy in USDA Zones 3 through 9. Once they are established, you no longer have to worry about replanting them every year.

With proper care, raspberries can live 20 years or more. You should therefore give them the best possible soil when preparing the raspberry planter box. Use good quality potting soil or work the garden soil with compost, manure, and sand to improve drainage. Perlite or vermiculite added to the soil hold moisture. Adding lime from your soil is acidic as raspberries prefer a neutral pH around 6.0. Neutralize strongly alkaline soils with aluminum sulfate.

The old farmer's almanac says pruning raspberries is important. Raspberries grow on sticks. A cane is produced in the first year, and fruit is produced in the second year. To maintain airflow in your raspberry raised bed. and keep the old sticks from taking up space and prune back the second year sticks after you've finished picking. It is helpful to know if you have summer- or autumn-bearing raspberries. However, if you don't know, simply remove the old canes after they have borne fruit and or in the later winter before growing new canes again.


HARVEST RASPBERRIES

To freeze raspberries, put them on a flat tray (only in one layer) and let them freeze. If you're lucky enough to have a lot, box up the frozen raspberries, put them back in the freezer, and freeze the next batch the same way.

When packed, they stay in the freezer for at least three months. Thawing raspberries will never have the texture of fresh raspberries, but that's not a problem if you want to use them in cakes, sauces, or beverages.

One tip for keeping frozen raspberries looking their best is to take them out of the freezer just minutes before using them. They'll stay in shape for a couple of hours and initially look lovely frosted with sugar - see the picture of the chocolate raspberry cheesecake below.
