The wicking beds are made of recycled food grade plastic and each 1m x 1m square module can store 110 litres of water at the roots where it’s needed most.
Trees, shrubs and groundcovers were planted into potting mix in the wicking beds to give them all the nutrients they need during their first six months. Coir is added at the base of growing medium to help water wick from the well into the soil mix. Hardy plants used include:
- Saltbush (Rhagodia spinescens)
- Rosemary (prostrate form)
- Garlic Chives
- Vietnamese Mint
- Lemon Balm
Seeds of the bush food plant, Warrigal Greens were planted and hopefully will germinate!
To reduce evaporation, the soil surface is mulched with sugarcane mulch.
A shallow water saucer provides a place for insects to land and drink and two insect hotels will be installed shortly to attract native pollinators.
In addition to the climate-sensitive micro-forest display we will run two seminars on ‘Edible gardening in pots’. This will be a great workshop for people living in apartments and townhouses.
This project is funded through the City Grants program managed by the City Renewal Authority. The grants are funded through the City Centre Marketing and Improvements Levy – paid by commercial land owners in the city centre.
