Tips for Growing Blueberries in Containers

by on November 13, 2012


Here’s what you need to know about growing blueberries in containers and raised beds:

1. Use a larger pot than you think you will need.
Blueberries need space – lots of space – and regular pots won’t cut it. Go with a pot that is at least 18” or you aren’t going to see the yield you could otherwise expect.

2. Use a high acid potting soil.
Blueberries need acidic soil with a pH of 5.0 to 5.5 to do well, so use a high acid mix or be prepared to amend your regular soil with acid-rich fertilizer.

3. Blueberries get lonely.
Unless you have one of the newer self-pollinating types, your blueberries won’t produce well. You need at least two different varieties in order to get a good yield.

4. Water well and water evenly.
While blueberries don’t like to sit in standing water, they do like to be watered often. To help keep the soil moist at all times, add a good layer of mulch to the top of the container to retain moisture.

5. Give ‘em their time in sun, baby.
Blueberries need sunlight, and plenty of it. Give them full sun for no less than 6 hours per day, preferably closer to 8. Without adequate sunlight, your blueberries aren’t going to produce up to their full potential.

6. Don’t go overboard with the fertilizer.
Resist the urge to overfeed your blueberries. A once a year application of an acid-rich fertilizer in early spring is all they need, and any more than that will not give any added benefit.

7. Don’t be in a hurry.
Blueberries grown in containers will take some time to produce well. If you aren’t in it for the long haul, blueberries might not be the right plant for you. Fruit may not be produced in abundance for the first two years or so.
