Capsicum Growing Guide

Capsicums are a popular vegetable to grow in warm areas, as they are relatively quick to produce a crop, don’t require a lot of special care, and come in such a lovely range of colours. Most varieties start off green, then change to red, purple, black, yellow or orange as they ripen.  

Prepare

Sun, sun and more sun is the key to growing capsicums, along with high temperatures. They are frost-tender, so in cold areas don’t even think about planting them outdoors until November. This isn’t too, as they take only three months to mature.

Refer to our Planting Calendar.

Plant

Like building a house a good foundation is the key to success in your garden. The better the soil, the better your plants will grow. If you are starting with an existing garden bed dig in organic matter like Tui Sheep Pellets and Tui Compost to your soil. Then you can add a layer of Tui Vegetable Mix. If planting in pots and containers, fill with Tui Vegetable Mix. Capsicum will happily survive in smaller areas if there is at least 25 cm depth of soil.

The best times to plant are early in the morning or late in the day, so the plants aren’t exposed to the hot sun straight away. Always water plants well before and after planting.

Planting in garden beds

  • Water plants thoroughly before planting and allow to drain.
  • Dig a hole, approximately twice the depth and width of the root ball of your plant.
  • Partly fill the hole with Tui Vegetable Mix.
  • Gently loosen the root ball of your plant and position the plant in the centre of the hole.
  • Fill in with Tui Vegetable Mix.
  • Press soil gently around the base of the plant.
  • Water your plant well.

 

Planting in pots and containers

  • Water plants thoroughly before potting and allow to drain.
  • Partly fill your container with Tui Vegetable Mix.
  • Gently loosen the root ball of your plant and position the plant in the container.
  • Fill your container with Tui Vegetable Mix up to 3cm from the top.
  • Tap the container gently on the ground to settle the mix.
  • Press soil gently around the base of the plant.
  • Water your plant well.

Nourish

Feed your plants and they will feed you. Plants use nutrients from the soil as they grow, so replenishing the nutrients ensures your plants grow to their full potential.

Select a fertiliser specially blended for your crop like Tui Vegetable Food. Feed capsicum planted in pots and containers with Tui NovaTec® Premium fertiliser. Well-watered, well-nourished capsicum will have a better chance of keeping insect pests and diseases at bay. While your capsicum is growing regularly apply a dose of Tui Organic Seaweed Plant Tonic to give them a welcome boost.

Protect your plants from the elements with layers of Tui Pea Straw Mulch, to help keep their roots moist and keep your garden weed free.

Be vigilant and stop unwanted insects and diseases from ruining your plants. Slugs and snails can be an issue - lay Tui Quash slug and snail control around young plants.
