Gardening Australia episode 36 2020
Guerrilla Green Walls
Costa visits a secret garden in the suburbs where brick walls are transformed into green space. Landscaper Newton Bishop has taken on the task of caring for his block’s communal garden, even the brick ventilation vent for the underground carpark, which he has covered with bromeliads and tillandsias that can cope with the heat and exposure of this open setting.
On the shadier side of the vent are epiphytic ferns that are also adapted to living on the trunk of a tree, and so don’t need soil. The frames of living plants he makes are also useful in rental situations, as they can easily be removed and taken with you.
Newton hangs the plants on timber boards and shows Costa how to make one.
FAQS – Growing Tea | Flowering coriander | Cockatoos and Vegies
Millie Ross explains how to grow your own tea, Tino Carnevale explains what to do when coriander goes to flower, and Clarence Slockee shares a tip to stop cockatoos pinching new growth from your vegie patch.
Cottage Garden Natives – Gardening Australia episode 36 2020
Jane shows how to update the classic cottage look with dazzling Australian natives. Who doesn’t love a cottage-garden with its generous, billowing mounds of soft, grey-leafed plants flowering in pastel shades and contrasting with tall spikes of colour and scented with fragrant herbs? However, many of the tradition plants such as foxgloves and hollyhocks, clematis and lady’s mantle simply don’t do well in many parts of Australia.
Jane has some suggestions of how you can create that chocolate-box look with a range of hardy Australian native plants that will cope much better with our hot, dry weather.

Consider Calcium – Gardening Australia episode 36 2020
Jerry explains the importance of calcium in a balanced plant diet for strong and healthy growth. Calcium is an essential nutrient for healthy plant growth, photosynthesis and cellular structure. Without calcium, plants can be stunted, become chlorotic (where leaves become pale or yellow due to lack of chlorophyll), or suffer from fruit drop and blossom end rot. A steady supply of calcium can prevent these issues, and is available with the addition of garden lime, dolomite, or gypsum to the soil.

The Great Indoors – Pests and Diseases
Guest Presenter Craig Miller-Randle shows us how to identify and treat houseplant problems to keep indoor jungles thriving.
Tino creates his own biochar that will boost crops and soil quality. Biochar is a soil additive that improves soil health and fertility. It’s essentially charcoal – organic material that’s burnt at high temperatures in a low oxygen environment, and then added to compost. Tino’s been experimenting with using biochar on vegetable crops and found it helps increase biological activity, and the nutrient and water holding capacity of the soil.
There are many ways to make your own biochar and Tino simply starts by digging a hole in the ground. It’s best to dig a cone shaped hole, around 1 metre deep by 1 metre wide. Always make sure to check and comply with fire restrictions in your area and have a reliable water source close at hand.
Plant Profile – Blue-leafed Honeysuckle
Sophie takes a close look at the Blue-leafed honeysuckle – a shrub that produces soft-pink flowers that smell as good as they look!
Josh explores how an Urban Forest Strategy developed by community volunteers is successfully bringing nature into the city. In built up urban areas, trees are under pressure from development, so some councils are implementing urban forest strategies to address the crucial role trees play in mitigating the impacts of climate change and providing a more liveable environment.
The Town of Victoria Park in Perth has an active strategy that started with good data to determine targets. The town measured an average of 10% canopy cover in 2016 and the aim is to double it!
Doubling canopy cover is no small task, and their strategy prioritises both targeted street tree plantings in pedestrian areas and protecting and expanding areas of remnant bushland. The much loved Kensington Bushland Reserve is one such area, and is not only protected for biodiversity and greenspace benefits, but the plants here are also used as stock for plantings across town to maintain local provenance – plants that are already well adapted to the local environment. Trees and shrubs are propagated at the City of South Perth Nursery and a team of passionate volunteers get them in the ground.
Clarence shares a tip to welcome a variety of native birds into your garden.
