Asparagus is one of the best vegetables you can grow at home because it’s so super healthy, extremely versatile, and fairly simple to grow too! But what if you wanted to grow asparagus in containers? Can it be done? The answer is yes! You most certainly CAN grow asparagus in containers. Maybe you don’t have enough space in your garden anymore, or maybe you live in an apartment – whatever the reason, growing asparagus in pots or containers is easy and we’ll show you exactly how to do it in this asparagus gardening guide!
How to Grow Asparagus in Containers
What’s great about asparagus is that it’s a hardy perennial that will keep on giving for up to 20 years! So once planted and well taken care of, your asparagus plant can actually keep on growing year after year for up to 20 years. Pretty wild, right?
Before you go ahead and plant your asparagus, think of how much you need. Each plant produces about one half pound of spears. Also keep in mind that the first two years of growth, asparagus are not edible!
Asparagus can be grown outdoors in containers in USDA zones 4a to 8b in full sun and light soil.
- Plant in the spring.
- Prepare a pot or container that’s at least 20 inches deep and 20 inches in diameter.
- Be sure that your pot or container has drainage holes.
- Add about 2 inches of gravel to the bottom of the pot. The gravel helps the asparagus from getting too much moisture and thus preventing rot and/or disease.
- Partially fill the pot with a garden-mix soil.
- Dig a hole in the center of the soil to a depth of about 8 inches and about 3 times the width of an asparagus crown.
- Place a spoonful of aged compost in the center of the hole.
- Now place the asparagus’ roots in the hole and spread them out with your hands.
- Cover the crown with about 2 inches of soil.
- Water the asparagus immediately after planting.
- Keep the soil moist as the asparagus crown grows.
- Once shoots start appearing on the crown, gradually cover them with soil, leaving about half an inch of the shoots uncovered.
- Continue covering the shoots each week until they reach the top of the soil level.
Caring for Asparagus Plants:
- Fertilize your asparagus plant about once a month by side dressing it with compost.
- Pick off any red berries that may appear on female asparagus plants.
- In late fall, cut the asparagus plants down to soil level to allow it to overwinter and prevent disease.
