Australian Guide on Growing Capsicum in Pots

The good news is that you can easily grow a capsicum plant in a pot and still have lovely fresh capsicums to harvest.

Do you want to grow your own capsicums but don’t have any available space in your garden? Or, perhaps you live in an apartment and only have a balcony or small patio area.

The good news is that you can easily grow a capsicum plant in a pot and still have lovely fresh capsicums to harvest. I’ve successfully grown a capsicum in a large pot near my back door in a spot that gets lots of sunshine.

There are just a few guidelines that you need to follow to grow capsicum successfully in a pot.

Choose your pot 

For a single capsicum plant, you want a reasonably sized pot that will accommodate the plant’s root system. Select a pot that is at least 30 to 50 cm in diameter.

Any type of pot will be suitable. But, remember that terracotta pots and unglazed stone or concrete pots will dry out faster than plastic ones. However, capsicums do like good drainage so as long as you water regularly, this shouldn’t be a problem.

You should ensure that the pot has good drainage holes so that the roots of the plant don’t sit in water.

Select a premium potting mix

When growing capsicum in a pot, you want to ensure that you select a premium potting mix to give your plant an excellent start.

Choose a potting mix that is marked for vegetable growing as this will also contain a decent amount of nutrients to feed your plant in the beginning.

Plant your capsicum using seeds or a purchased seedling

Capsicums are easy to grow from seeds and this is a more cost-effective way to grow your plant if you start early enough. You can start your seedlings indoors in late winter for a head start.

To do this, you want to fill a seedling tray with a seed-raising mix and plant a few seeds into this. Always sow a few more seeds just in case some of them don’t germinate.

Keep the soil moist until you see the seedlings start to germinate. Make sure that your seedlings are placed in a warm spot such as a bright window sill to ensure good germination.

Once your seedlings are around 5 to 7 cm tall, they can be transplanted into their full-size pots. Ensure that you only plant one seedling per pot as the root system of the plant will need enough space to grow well.

Alternatively, you can purchase some established seedlings from a nursery or garden centre to speed up the process. Once again, you only want to plant one capsicum in each pot.

Place your potted capsicum in a sunny spot

Capsicums do need plenty of sunlight to thrive and produce their delicious fruits. Therefore, you want to place your potted capsicum in a spot on your balcony that receives at least 6 hours of sunlight daily.

However, one of the advantages of growing capsicum in a pot is that you can easily move it around so that it gets sun for the most part of the day.

Caring for your potted capsicum

Once you’ve positioned your capsicum in a sunny spot, there are really only two things you need to do to ensure that your plant thrives.

First, you want to ensure that you water your plant regularly. Always remember that the soil in a pot will dry out much faster than garden soil. 

Therefore, you might find that you have to water your plant at least every couple of days during the heat of summer. Always check the moisture content in the soil before watering.

The easiest way to do this is to poke your finger into the soil and if the top 5cm of soil are dry, then it’s time to water. Alternatively, you can use a chopstick to check whether the soil is dry or still moist.

If the stick comes out clean with no damp soil attached, then you can water your plant. 

The second thing that your capsicum plant will need is fertiliser. For potted capsicums, you have two options. 

You could either add a slow-release fertiliser in spring or you could use a liquid feed instead. Select a liquid fertiliser that is organic such as fish emulsion for the best results.

You want to apply this on a weekly basis during the warmer months as part of your regular watering schedule.

Then, all that’s left to do is to harvest the fruits as they grow and ripen.

FAQ

Do capsicums need full sun?

Yes, capsicums need at least 6 hours of full sun on a daily basis.

Do capsicum plants come back every year?

In the cooler parts of the country, capsicums are grown as annuals and will need to be planted each year in spring. However, in warmer regions, your capsicum plant should continue to grow all year round.

Do capsicums ripen once picked?

No, once capsicums are harvested, they won’t ripen any further or change colour.
