FROM THE EDITORS DESK… Dear Readers, A nip in the air herald’s a changing season and, although some days the temperatures may still peak at 30 0C, the cooler evenings bring relief and better sleeping conditions. We’ve gone small in a big way this month, looking a boundary screens and slope plantings for small estate-sized gardens. These ideas will also work just as well when designing small areas within large gardens. If you battle sandy soils daily, struggling to establish an attractive, diverse garden, we look at ways to work with the soil and provide a comprehensive list of plants from which to choose. We provide a shortened list within the magazine, with a link to access the full list. In our plant focus this month we discuss the confusion surround the variegated Plectranthus groundcover, Plectranthus madagascariensis, and a neat, fully green species, P. aliciae; on show too, is a most beautiful Anisodontea shrub, Classic Cerise,
and despite it being a hybrid, it attracts myriad insects. Lastly, a new succulent groundcover in my garden, a gift from a friend, is fast becoming a favourite – Crassula obovata. 3 section designs from Miles Steenhuisen’s garden have taken our fancy, plus, do you know the value of that weed you have just pulled out? We discover one that is a host plant for a gorgeous butterfly. The autumn garden section provides gardeners with a few tasks. Whatever is on your to-do list this season, do it mindfully! Happy reading
Anno

The Autumn Garden SEASONAL CHANGE Autumn arrived overnight and we awoke to cool, misty 19 0C, a full 17 0C drop from the previous day. Wonderful! Though the day-time temperatures can still hit the high 20’s the early morning and evening nip in the air signals changes in the natural world. The length of the growing seasons vary, but generally autumn is the end of the important growing season and there is a general

Halfway up the slope, surrounded by spiny plants will make your life difficult! • Deep-rooted plants near the top of the bank will effectively hold the soil in place. • Use evergreen plants with good leaf cover to diffuse the rains that will otherwise wash soil down the slope. • Steer clear of vigorously spreading
groundcovers as they can rapidly smother their companions and require frequent trims. • Where the soil abuts paving, use an edging material like log rolls, to secure it and prevent soil wash. For ease of mowing and curtail the spread of lawn grass into the planting area, you can choose to continue the edge along the length of the slope to include where the bank meets lawn. • Use plants to spill over and soften the built-in edge. A well-dressed bank provides a sweep of colour through the year.
