How to Plant Raspberries in Pots

Choose 15-inch pots with drainage holes at the bottom for your raspberries. Fill the pots with a mixture of 80 percent compost and 20 percent potting soil.

Plant one raspberry plant in each pot. Make a hole for each plant that matches the size of its root ball. Place the raspberry plant in the hole and backfill. Pat the soil around each plant with your hand to release air pockets.

Keep the soil in the pot moist at all times. Water the plant frequently after the first few weeks of planting, allowing the water to run through the soil and out the drainage holes.

Feed the container-grown raspberries a diet of all-purpose fertilizer during the growing season. Apply the fertilizer according to label instructions. Most raspberries require fertilizing at least once a month.

Harvest the raspberries as the plants produce. Most raspberry plants will begin flowering 6 to 8 weeks after planting and will produce fruit within 10 to 12 weeks of planting. Once fruit production begins, it usually lasts for approximately 60 days.
