How to Grow Broccoli Indoors in Containers

UrbanFig: Broccoli

As part of our ongoing look at growing vegetables indoors, today we are taking a look at growing broccoli in containers. If you haven’t seen it before, you might want to read our growing guide on growing broccoli as it contains some great info about the individual needs of one of the most popular plants in the vegetable garden.

To grow broccoli indoors you will need some patience as it can be a fickle plant when the conditions aren’t just right. The good news is that you don’t need to worry about pollinating broccoli because the vegetable we eat is actually the flowers of the plant before they bloom! How crazy is that?  Here’s how to grow broccoli indoors in a few simple steps:

1. For best results, select a container that is no less than 8” deep and 18-20” wide for each broccoli plant. Given the right conditions they can grow quite large and need a large container to establish an adequate root system. Fill the container with a good quality container mix and plant the seed according to package directions.

2. Water thoroughly and make sure your container gets plenty of light. If you are using an artificial light source, situate the container as close to the light as possible. When growing seedlings indoors for spring transplanting, I keep the light source about 3” away from the plants, so follow that same rule of thumb as the seeds are getting started for best results. Allow for 8-10 hours of light per day.

3. Keep the soil moist (but not wet) at all times.

As a general rule, you should be prepared to add 2-3 weeks or more to the growing time for any plant that you are attempting to grow indoors, and broccoli is no exception.
