How to Grow Raspberries in Raised Beds


A raised garden bed is a popular way to grow vegetables. Raised beds elevate the root zone of plants above the surrounding soil, allowing a plant's roots to warm up quicker and the soil in a raised bed to drain easier. Warmer soil conditions combined with faster draining soil will ward off root rot and soggy soil problems, which makes raised beds a good idea for raising raspberries. Raspberry plants hate "wet feet," which make them hard to grow in areas with high-clay-content soil.

Building a Raised Bed

Step 1

Choose a sunny location for your bed and decide on the size and shape of the bed.

Step 2

Add a rich, loamy soil mixture into the to the area where you will be constructing your bed.

Step 3

Move the soil around with a shovel so that the average height above ground level in the entire bed is between 1 1/2 and 2 feet, with the minimum width being 2 feet. Work the soil with a garden rake so that it slopes gently down to the existing ground level around the edges.

Growing Your Raspberries

Step 1

Add organic matter to your bed, such as compost, peat moss or manure, at a rate of 2 to 3 bushels per 100 square feet. Mix into the soil with a rototiller.

Step 2

Add ammonium nitrate to the soil at a rate of 1 lb. per 100 square feet and till in to aid in decomposition of your organic matter.

Step 3

Dig a hole 1 foot wide by 1 foot deep per plant. Position each plant in the center of the hole and spread the roots out. The location where the roots attach to the cane should be 1 to 2 inches below soil level. Fill the hole with soil and press firmly to remove any air pockets. Repeat for all other plants, with spacing of 3 feet. Rows should be 6 to 8 feet apart.

Step 4

Water thoroughly to settle the soil and prune the cane height to 6 inches if not already done by the nursery.

Step 5

Build a trellis system for each row. At the end of each row, bury a 6-foot-tall 4-by-4 post 1 foot into the ground. Screw one 18-inch-long length of 2-by-4 board horizontally at the top of each post and ensure it is centered on the post. Pound a nail into each end of the 18-inch-long boards, leaving 1/2 inch of the end of the nail exposed. Stretch 12-gauge wires between the posts and tie them to the nails. Pound a nail into each side of the posts 30 inches from the ground, leaving 1/2 inch of the end of the nail exposed. Stretch 12-gauge wires between the posts and tie them to these nails.

Step 6

Fertilize your raspberry plants 4 to 6 weeks after planting them. Apply 1 tbsp. of 12-12-12 fertilizer per plant.

Step 7

Water throughout the summer to provide 1 inch of water per week when rainfall lacks. The rainfall and irrigation combined should equal this figure.

Step 8

Cut the 1-year-old canes level with the top wire in the spring, using pruning shears. Cut 2-year-old canes back to soil level at the same time.

Tips and Warnings

  • Refrain from applying supplemental water in the winter months. The raspberry plants can easily rot if kept excessively moist in the cooler winter months.
