May in my Garden

What’s looking good 

Here in the Adelaide Hills the season is changing, with many beautiful days and very cool nights. Not much decent rain yet, but as I write this, there's a fine drizzle that keeps the garden growing.

Beauties in the garden include the Dahlias, Cosmos, Salvias, Roses and early Chrysanthemums. And I'm being delighted by the gorgeous Autumn color of the Chinese Pistachio (Pistacia chinensis), Liquidambar styraciflua, Malus varieties (Crabapple) and 'Red Emperor' Chinese elm, which is magnificent in it's fourth year.

What to do

  • It's again time to prune, tidy up, fertilize and mulch when we get enough rain. I like to wait until there has been a good fall of up to 40mm, so the soil is damp before mulching.
  • If you have a worm farm, (which I hope you do!) remember to keep them damp and feed your worms with a good mix of carbon and nitrogen. Add manures, weeds, kitchen scraps and cardboard/paper, and they will thank you by breeding and turning the waste into wonderful castings.
  • Autumn is a great time to plan your garden by improving soil, looking for empty spaces and deciding where to plant your veggies.
  • Semi hardwood cuttings and autumn seeds can be started now, taken over the winter then planted in the spring.

Our Clients Say

Amanda was extremely flexible in dealing with our needs, which often changed from week to week – always tackling each task with enthusiasm.  Some of her major achievements include:
  • A delightful dry stone walled pathway
  • Clearing and re-planting of an extremely steep bank behind the house
  • Laying of pathways and planting an avenue of shrubs for screening
  • Selection, placement and planting of an array of wonderful trees, shrubs and other plants
  • Installation of an irrigation system
If you are looking for a landscape artist who is ‘out of the box’ – Amanda is certainly the one!  Her approach is individual, her enthusiasm abounds, and no task is too small.
Jenny & Charles, Crafers, South Australia
I would like to thank you so much for the work you did in building our garden, and then planting it with such a lovely variety of plants and shrubs. I particularly like the way in which you used the large stones to make such a natural and attractive surround to the car park and walls to retain the flower beds.  I was also very pleased that the work was done to the budget you had indicated and done in a very timely way.
Dr John Morgan, Bridgewater, SA
Thank you for taking on my challenging ‘jungle’…for being able to view the ‘as-is’ and envisage the ‘could-be’.  The artistic, the fun and the practical are all brought together in your mind’s eye – and then you set out the plan and the process.  The icing on the cake was your understanding of permaculture principles and how they can be incorporated into a simple back yard.  You allow our idealism to be caught up into our reality.  That makes for a truly fulfilling garden.
Esmae Boutros, Melbourne
We have a native garden, designed and established by Green Platypus Gardens, that is the envy of the street. GPG listened to our desires while providing professional knowledge of soils and plants, along with cost-effective strategies.
H & D Bodein, Dover Gardens
Amanda helped us design an incredible garden plan for your 1 acre block. She came up with ideas we’d never have imagined that were both creative and practical. Thank you! Couldn’t recommend her more. 5 stars!
Verity & Tom, Finniss
Amanda from Green Platypus Gardens is a good listener –  her designs are creative and functional and she comes up with interesting options that are outside the square. She serves the client’s interests and goes the extra mile. Amanda knows her stuff and is able to make it accessible to the novice gardener.  I was never into gardening before, but she made it look easy and fun and now I love tending our patch. We are both loving our garden!
