April Gardening Guide

As you harvest the last summer crops it's time to plant your patch with winter staples including broccoli, cabbage, celery and silverbeet. Freshen the flower garden with pansies and polyanthus and don't forget feijoas in the fruit garden.

What to plant in April

In the vegetable garden

  • Dig in Tui Compost and Tui Sheep Pellets before planting to replenish nutrients used by previous crops. Compost is also an excellent water saver.
  • Beans - tie up floppy plants, and keep them well watered - they should keep producing for another month or so.
  • Brussels sprouts - stake taller plants to prevent them from falling over.
  • Carrots - thin rows of carrots to ensure the roots develop evenly.
  • Sweetcorn - pull out plants once they have finished, and add the stems to the compost heap.
  • Tomatoes - in cold areas, pull out plants and leave any green fruits on a windowsill to ripen in the sun (this may take a few weeks).
  • Plant beetroot, broccoli, cabbages, cauliflowers, cavolo nero, celery, kale, lettuce, radishes, rocket, spinach, silverbeet, spring onions, coriander, parsley, rosemary, sage and thyme.
  • Harvest beans (all types except broad beans), beetroot, broccoli, cabbages, capsicums, carrots, cauliflowers, celery, chillies, courgettes, cucumbers, lettuce, marrows, peas, potatoes, sweetcorn, tomatoes.
  • Feed established plants once a month with Tui Organic Seaweed Plant Tonic.
  • Lay Tui Quash to control slugs and snails, and spray aphids and whitefly if they are still a problem.

In the fruit garden

  • Pick grapes, apples, Chilean guava, pears, rhubarb, walnuts, passion fruit, late peaches.
  • Plant evergreen frost hardy fruits such as feijoa (see the feijoa growing guide here) and Chilean guavas.
  • Remove runners from strawberry plants and pot up into Tui Strawberry Mix ready for planting out in winter.
  • Remember - fruit requires a position in full sun. Shelter from prevailing winds is preferable.
  • Aphids, whitefly and scale insects may be about, blast off with a hose or select a suitable spray from your garden centre.
  • Pruning - once nectarines, peaches and plums have finished fruiting prune to shape and to remove any dead or diseased branches.
  • Add a layer of Tui Mulch & Feed around the base of fruit trees, to keep the soil warmer over the winter months and keep the area weed free.

In the flower garden

  • Pick scabious, Peruvian lily, poppies, marguerite daisy, statice, Japanese anemones, roses, coreopsis, echinacea, strawflowers, dahlias, lilies, sweet peas, gypsophila, cosmos, zinnia, pineapple lily, agapanthus, hydrangeas.
  • Sow bellis, polyanthus, violas, primula, pansies, flowering kale, poppies, wildflowers, gazania, dianthus.
  • Plant autumn hanging baskets with bellis, lobelia, polyanthus, flowering kale, primula, pansies, violas, snapdragons, wildflowers, sweet william, cineraria.
  • It's not too late to plant bulbs for spring flowering. Fertilise existing ones with Tui Bulb Food.
  • Apply a side dressing of Tui NovaTec Premium fertiliser to shrub borders and flower gardens.
  • Add layers of Tui Mulch & Feed or Tui Pea Straw Mulch to garden beds and pots to conserve water, reduce weeds and add valuable nutrients back to the soil.
  • Prune back summer flowering perennials and bulbs that have finished for the season, to tidy up garden borders and beds.
  • Lift and divide overgrown perennials.
  • Save and dry seeds of summer flowers for sowing in the spring.

  • Wow, so much to do! I am new to the guides and find this really helpful

    Joanna Dickinson

  • Hi Joanna, that's fantastic to hear. Good on you for growing your own! We're happy to help with guides and tips - check out our Facebook and Instagram too. Happy gardening from the Tui Team

  • Yes there seems a lot to do to keep the garden growing etc. With the weather wet and cold like it is, one does not feel like going outside. You have reminded me to get my cabbage seeds in before too late. Thanks

    Sharon

  • Is it to late to trim back hedging plants - eg Pittosporum's? thanks :)

    Erin

  • Hi team, my capsicum started fruiting very late this summer (he'd been overshadowed by a very enthusiastic courgette plant). So I now have a bunch of small fruit on the plant. Will they grow any further or should I call it a day and pull the plant out? Thanks!

    Emma

  • We put in a Billington plum tree nearly 3 years ago, the first year we had 3 plums and this last year we got only 1. A friend suggested that we probably need a pollinator. Is this the case and if so, which variety of plum should we plant?

  • First time reader, lots to do but feel more inspired than ever!

    Lyn Little

  • Hi Lyn, autumn is a busy but exciting time in the garden. Great to hear you are feeling inspired! Happy gardening from the Tui Team

  • Hi Emma, great work on growing your own summer crops. If the weather is warm enough they will continue to grow for a bit longer. It really depends where in the country you live? We still have capsicums growing well here in the Bay of Plenty but the weather is starting to cool. You could leave the plant for another few weeks to see how it goes, as you might still get some fruit! Happy gardening from the Tui Team

  • Hi Judy, plum trees can take a few seasons to produce fruiting spurs, Billington is self fertile so you do not need a second plant. It can take up to 5 years, so a little more patience may be required. Feed with Tui NovaTec Premium fertiliser in spring and apply Tui Organic Seaweed Plant Tonic regularly. All the best ^Tui Team

  • Hi Erin, now is a great time to prune back hedges, as it allows the plant to re-cooperate over winter ready for a new flush in the spring. A side dressing of fertiliser will help now as well, and a layer of mulch will help keep the weeds away and the soil warmer too. ^Tui Team
