How to Grow Raspberry Bushes Inside
- 1). Mix together 4 parts compost and 1 part peat moss to create potting soil for the raspberry bush.
- 2). Fill a 15-inch pot with the potting soil. Do not fill the pot to the brim with soil; leave 2 to 3 inches of space from the soil to the top of the pot.
- 3). Plant a single raspberry root in the very center of the pot, 1 to 2 inches deep into the soil. You may plant up to 5 roots in the pot and transfer each seedling to a new container after growth occurs.
- 4). Place the pot near a window where it will receive full sunlight.
- 5). Keep soil evenly moist. Check the soil every day or every other day for dryness and water as necessary.
- 6). Place a wooden stake into the container or next to the container. The stake may be up to 8 feet tall. It will serve as a support system for the raspberry bush.
- 7). Apply general-purpose fertilizer to the soil once a month during the growing season (March to September).
- 8). Prune fruiting canes with shears after you harvest the berries. Cut the canes all the way back to the soil surface.
