Kevin Parker, a senior horticulturist at The Greenery Garden and Home, says the trick to growing capsicum is to plant them at the right time.
"Everyone is keen to get their summer vegetables in. But if you plant them too early, and then you get a cold night, it will kill the new plants.
"I don't tend to plant tomatoes or capsicum until probably late October because you know the weather has set in, and it's warm. Some people have greenhouses to grow summer veggies early, and that's fine, and they will grow quite well."
How to plant capsicum
To grow capsicum from seed, sow seeds in single containers about 1 cm deep and water in. Keep the seedlings outside during the day and inside at night. They do not tolerate any frost.
Once they are about 10 cm tall and the weather is consistently over 20 degrees, you can plant in a nice sunny spot in your garden.
How long does capsicum take to grow?
Some patience is required when growing capsicum. It's a slow-growing plant which can take up to 3 months to grow, but it's worth the wait.

Capsicum doesn't like wet soil. They need to be a potting mix if you plant them in a pot.
After planting your capsicum in the garden, it will need watering a couple of times a week for the first month. After that, you can water your capsicum deeply but less often (about once a week) to encourage stronger roots.
As well as planting at the right time, the trick to growing capsicum is to feed them.
"To encourage better size capsicum, you need to feed them regularly. Use either a liquid or dry fertiliser. You need to keep feeding them," says Kevin.
Capsicum is sometimes prone to getting caterpillars on the leaves in the summer, the same as tomatoes.
Keep an eye on the plant and pull off the caterpillars when you see them if you've got a keen eye. Here’s how to keep caterpillars out of your garden.
What's the difference between red and green capsicum?
The main difference between a green and red capsicum is the red capsicum has been left on the plant longer.
"When you go into a fruit shop, and you buy a green or a red capsicum, the red has been harvested later off the same type of plant, making it sweeter," says Kevin.
How to grow capsicum in pots
Capsicum can be grown in larger pots. However, they prefer to be planted in the ground of your veggie patch.
Kevin says, "If you plant them in a pot, they must be a potting mix, and the pot must have holes for drainage."
