Large patio and deck planters are ideal for growing asparagus in a container garden. You can use the larger pots for the border or background of your container garden area and enjoy the rich green color of asparagus. Asparagus is perennial and will return annually, without replanting.
- Skill level:
- Moderately Easy
Things you need
- Asparagus crowns with roots
- Several one to five gallon planting containers
- Medium-sized rocks
- Potting soil
- Electric drill
- Hand trowel
- Watering can
Set containers in the desired location, with full to partial sun. Containers will be heavy after planting. Plant your asparagus in its permanent location, rather than planning to move heavy containers.
Gather and bring your supplies to the area of the containers. Combine potting soil, a small amount of cow manure and compost items (see Tips). Mix well.
Drill large drainage holes in the bottoms of the containers. Drill a second drainage hole two inches above the bottom of the container and a third drainage hole on the same level on the opposite side of the container.
Fill the bottom of the container with large rocks and dry leaves. This will provide drainage and nutrients for the asparagus plants.
Fill the container 3/4 full of the potting soil mixture from step 2. Repeat steps 4, 5 and 6 for each container.
Use a small trowel to dig a six-inch hole in the center of the soil in the container. Repeat for all the containers.
Plant one asparagus crown in each container. Lightly squeeze the roots and loosen. Roots should not be bunched tightly together. Place the asparagus crown's roots into the hole in the soil. Fill the hole with the potting soil mixture until only a small amount of the asparagus crown is visible. Repeat with each container.
Fill a watering can with water. Water each pot thoroughly until water drains from the drainage holes.
Tips and warnings
- Plant asparagus after the chance of frost has completely passed. Use dry leaves, crushed egg shells and grass clippings for your compost items. Place containers in full sun.
- Asparagus needs plenty of room for roots. Do not plant more than one asparagus crown per container.
