Tony's Tips - November 2025
Spring has been kind to us this year, with all that lovely rain helping gardens and lawns come to life. If you’ve been feeding regularly, you’re probably seeing the results with lush growth and vibrant colour everywhere.
The first roses of the season are putting on a show right now. Once those blooms start to fade, give them a tidy-up trim and a good feed to help them flower again just in time for Christmas.
With the warmer weather, it’s the perfect moment to plant Basil and Vincas. We’ve also got a beautiful new range of Hydrangeas in store, plus fresh new-season Mandevillas, available in both compact and climbing varieties to suit any space.
If you’re hosting Christmas this year, now’s the time to plant your annuals. They’ll need about six weeks to fill out and be looking their best by the big day.
Hydrangeas are ideal for planting now and this month you’ll find our widest selection of the year. Pop them into compost-enriched soil or a large tub with premium potting mix, and place them in a partly shaded spot such as the east or south side of your home. They also make stunning cut flowers and after Christmas, give them a good prune to encourage fresh growth.

Things to do:
1. Prune your lavender
Winged Lavenders (like Avonview, Purple Reign and Princess) will finish flowering soon. Cut them back hard after flowering, leaving a little green growth.
Never prune Lavender to bare wood and start pruning young to stop them becoming woody.
2. Control pests
November is the key month to prevent outbreaks of Azalea Lace Bug, Lawn Beetle Grub and Lilly Pilly (Calypso) Beetle. We’ve got everything you need to stop them early.
-
Watch for fungal diseases: It’s been the perfect season for fungal growth, especially on roses. Spray now and repeat in two weeks to stay ahead.
-
Tomatoes benefit from a light dusting as a preventative measure.
3. Third times a charm
Give Gardenias their third feed of Harry’s this Spring and water over the foliage on hot days.
4. Focus on your veggies
Feed fruiting veggies such as tomatoes, capsicums, eggplants, chillies, cucumbers and zucchinis with a high-potassium fertiliser (like Grow Better Fruit and Citrus Food) to encourage strong fruiting.
