Painting with Plants

Costa meets a pair of artists who have transformed a bland rental yard into a colourful space that reflects and inspires their creativity.Both Cal and Doug had parents who were keen gardeners. But it’s still incredible that they have filled in so many bare patches to become colourful garden beds. Both see gardening as linked to their artwork. Their landlord was very supportive and allowed them to experiment by adding garden beds between established trees.

One shady area has been turned into a fernery with a pond in an old bath. It includes a section where bromeliads and other plants that like good drainage have been arranged in a corner while still in pots, half buried in the garden and disguised by a thick layer of mulch. Many of these shade-loving plants have variegated foliage and Doug also like to include red-leafed plants – both in the garden and in his art.

‘Erthly’ Delights – Gardening Australia episode 11 2021

Millie explores the Garden of St Erth, where history and heritage plants form a beautifully productive patch, despite the extreme climate.

Head gardener Julian Blackhirst has seen a lot of change in the 10 years he’s worked here, but the garden dates back to the gold-rush days, when Blackwood was called Simmons Reef and was a bustling community of more than 14,000 hopeful diggers. The township’s main street runs through part of the present-day garden, but the soil was completely disturbed and destroyed so has been rebuilt with compost and mulch over the past 40-50 years.

From 1980 it was owned by Geelong Grammar headmaster and garden writer Tommy Garnett, who was awarded an OAM for his services to horticulture. The garden is used to experiment with lots of plants and the borders are always changing. It includes a number of unusual trees and experimental plants too.

Growing under the Eucalypt canopy is the most challenging area but the climate is extreme at both ends; cold wet winters and hot dry summers. There is dry-climate perennial border that receives full sun and gets no watering. It features a cotinus that is coppiced every year.

Hand Watering

Jerry explains the benefits of hand-watering. Hand watering and observation are fundamental principles of successful gardening, says Jerry. Rather that use a timed irrigation system, he prefers to get out in to the garden to check each plant and he goes, see what has changed and pick up on any potential problems early.

By simply removing one leaf affected by pests or disease ca stop it spreading to the whole plant. Feeding damage can be identified to the pest species and help you work out how best to deal with it.

House Leeks – Gardening Australia episode 11 2021

Sophie looks at House Leeks – cool climate succulents named from a time when they were used to patch roofs! Sophie loves succulents and has a large collection of House Leeks – or Sempervivums. These low-growing plants will take part shade and come in a range of colours and patterns. All are great pot plants because they like good drainage.

To propagate, simply pull off new ‘pup’ plants that form at the edge of the mound; they will already have some roots and can be potted up straight away. The name House Leek comes from the habit in Europe of using these plants to patch any holes in a thatched roof.

Community Caring

Clarence visits a shared green space that has forged some great friendships as well as providing lots of healthy food. Clarence visits a garden that is a meeting place for the community as well as providing food and practical support. He meets up with former colleague Brendan Moore, who helps run the garden through his role with the Royal Botanic Garden Sydney.

Repotting Blueberries

Josh explains when and why plants need repotting and gives his blueberries a new lease on life. Blueberries (Vaccinium cv.) grow well in pots but in Josh’s plant the potting mix level has dropped, because the organic matter in it has broken down. If not dealt with, the plant will decline; it needs repotting and the best time to do this is between mid-autumn and late spring.

Other signs a plant needs repotting is firm, solid roots; yellowing leaves (despite a good fertilizing campaign), and soil drying out quickly or water flowing down the side of the root ball and not soaking into the mix.
