April - What to plant

April - What to plant

25th Mar 2024

Autumn is a fantastic time in Tasmania as gardens become a delightful display of colour and vegetable gardens are ready to be revitalised in time for some cool weather magic. 

Now is the time to sow Garlic, Broad beans, Raddish, Snow Peas, Turnip and Spinach from seed. Plant seedlings of Broccoli, Cabbage, Cauliflower, Celery, Onion, Leeks, Swede, Kale, Winter Lettuce, Rocket and Spring onions. If planting Brassicas, consider purchasing seedlings so that they have a good start prior to the cooler winter weather and feed with Powerfeed to add an instant boost of nutrient.


If resting a garden bed over the winter now is the perfect time to add a mixed green manure crop. Adding a green manure crop will enrich your garden beds ready for spring planting.1kg bags are available for planting now.

Broad beans can be easily grown from seed and will produce a huge crop that can be stored or frozen. Growing broad beans from seed is straightforward and can be incredibly satisfying. These plants not only provide a tasty and nutritious crop but also contribute to a healthy garden ecosystem through nitrogen fixation

  • April is the time to plant flowering annuals such as Alyssum, Calendulas, Dianthus, Delphiniums, Forget Me Nots, Lobelias, Polyanthus, Pansies, Primulas, Snapdragons, Stocks, Sweet Peas and violas.
  • Planting of spring flowering bulbs is still happening for the harvest of colour ahead. Mix blood and bone with potassium into the soil when planting – this will get them off to a good start once the roots start developing helping to reduce the risk of any bulbs rotting.
  • Lots of native shrubs and trees are beginning to arrive this month – this is the ideal time to plant as it gives the plant time to establish and firm up in the ground before the onset of winter. Remember to stake tall trees when planting.
  • Prune back and fertilise shrubs and climbers as they finish flowering.
  • If your noticing patches in the lawn check for nearby holes as this could be lawn grubs attacking!
  • Ripening pumpkins can be sat on wooden placemats to reduce the risk of rotting
  • Keep an eye for caterpillar leaf roller and Azalea leaf minor which often attack azalea over the coming 8 weeks
  • Plant up pots and containers for autumn and winter colour. Always use premium quality potting mix and feed weekly with a liquid or soluble flowering plant food
  • Repair lawns that have suffered from the dry summer and resow now if required
  • Prune Raspberry canes in late autumn and then feed and mulch; ask us how to prune summer vs autumn fruiting varieties or keep an eye out for our raspberry pruning guide in next months blog
  • New season’s roses and fruit tree's will be arriving in winter. We are now taking pre-orders on our website
  • Our first delivery of Camellia, Azalea and Daphne have arrived ready for Autumn planting.
