If you’re a true green thumb, you probably already know when to mow, prune, pluck, plant or trim your chosen plants, but for some this may be a reliable source of info throughout 2024 – happy gardening!
Avoid pruning if you can, if you must, then take care, your garden is extra fragile in the summer heat.
Its time for the living Christmas tree to find a new home outdoors. Move them to a sunny spot, water and fertilise them and then plant them in turned soil.
Check your houseplants for bugs, control with White Oil if needed.
Your lawn might also be attracting killer bugs, if you’re finding brown patches it could be army grub. Ask your garden guru which product is best and apply all over the garden so they know they’re no longer welcome.
Hydrangeas and geraniums are finished blooming and need a prune. Cut off any long stems of agapanthus too.
Roses will also need a summer prune; cut off one- third of growth, fertilise with poultry manure, then rose food.
Citrus should be fertilised this month. Potted plants should only be fed with a slow-release, not citrus food, as this will cause leaf drop.
Garden varieties need poultry manure fed out under the drip line: water before and after application, then two or three weeks later, apply citrus fertiliser, again, watering well.
Prepare flower and vegetable beds this month by digging in poultry manure plus an all-purpose plant food. St Patrick’s Day is traditionally when sweet peas are planted.
Camellia sasanquas are beginning to bloom – they are ideal for disguising an ugly fence and look great planted along a narrow driveway.
Select bulbs for spring this month. Gladioli corms can be lifted and stored in a dry place.
Remember to plant poppies on Anzac Day in beds prepared with poultry manure at least one week prior.
Boost parsley with blood and bone for instant greening.
Cut back other herbs beyond their prime and apply Flourish. Tulips and hyacinths need two weeks in the fridge before planting to trick them into thinking it’s really cold.
Give roses a handful of blood and bone to keep them flowering.
If planting new-season roses, don’t fertilise, but do water daily.
Once Sasanqua camellias have finished blooming, it’s a great time to prune.
Lawns should be sprayed to eliminate bindiis before seeds become dispersed.
A great month for pruning – not spring-flowering trees and shrubs.
Roses should be pruned this month (frost-prone areas can wait until August).
Stone fruit that suffer from leaf curl should be sprayed with Copper Oxychloride during the last two weeks of July (then again during early August).
Crepe Myrtles should be cut back to within several centimetres of last year’s growth – don’t prune back to the same spot as ugly calluses will appear.
Fertilise citrus this month; only use slow-release on potted plants.
Feed ground-grown plants with poultry manure, followed several weeks later with citrus food.
Hydrangeas that have been pruned back to two plump eyes should be fertilised, giving consideration to colour.
Once camellias are finished flowering, deadhead and trim to shape, fertilise and mulch with peat moss.
Early tomatoes can be planted in well-manured soil.
Eradicate weeds before lawns are fertilised.
Don’t fertilise lawns until they are actively growing.
Agapanthus, murraya, gardenia and other flowering summer plants should be fertilised with cow manure.
Don’t prune tropical plants until warm weather is established.
If gardenias develop yellow leaves as they are setting flowers, apply chelated iron and keep well-watered.
Camellias and azaleas should be fertilised after flowering. Use a slow-release fertiliser for potted plants.
Roses are prone to aphid attack on their new growth; keep this under control with pyrethrum or Malathon.
Hibiscus making new growth will need cow manure and chelated iron to prevent yellow leaves.
Give native shrubs that have finished flowering a light prune.
Summer-flowering annuals and vegetables will benefit from an application of blood and bone.
Watch for fruit fly attacking tomatoes, stone fruit and other ripening vegetables.
Use fruit fly baits and paint tomato stakes with a spreadable paste of Vegamite and Malathon (no specific ratio).
End of the year again, and it’s mulching time, ready for the long, hot summer.
Use peat moss around the root surface of azaleas and camellias and mulch the rest of the garden with sugar cane mulch. Plant annuals for Christmas colour.
