Syncarpha argyropsis: needs drought having your soil tested just so you can decide on a few garden plants. Test your plants instead of your soil If you’ve got a big planting project planned, you can always try out the species you have in mind before committing. Get just one of each species you’re planning to use and see how they do in your growing conditions before getting hundreds. There can be other elements other than the soil itself that will make or break your plant choices. These include humidity tolerance, disease resistance and the temperatures you experience. Even if you think you know the plants from experience in other re- Dodonaea: handles drought but gets taller when there is moisture Bauhinia galpinii hates hard frost, poor drainage gions of the country, or even just a few kilometres away, it’s worth doing a few little trials before you go for a mass planting. I’ve already seen incredible disease resistance in regal Pelargoniums, but when I mass planted them just a few kilometres away from the site they loved, they didn’t like the heavy dew, and struggled. The soil was similar, sun exposure was A-OK, but the daily moisture on their leaves didn’t suit them at all. Garden irrigation timers: yes or no? Having irrigation set on a timer can be very handy when you’re going away, have a large garden, or when you have miles of drip irrigation in Selago purple: tolerates dry conditions once established Carpobrotus: salt tolerant place to establish a wind-break, but you can stand to lose hundreds of liters of water for nothing if your irrigation isn’t regularly checked and maintained. If at all possible, set your timers for a time of day when you can physically check if the irrigation is working as it should. One emitter blasted off its water-feed pipe, or breaches in the pipe itself can result in a huge waste of water while plants die of drought. Another reason why I don’t really like timers is that they don’t take prevailing conditions into account. Let’s say it rained last night. You obviously don’t need to irrigate, but Aloe arborsecens -tolerates heavy dew
