Tropicals & Tender Perennials: Setting up Hoyas, 1 by tropicbreeze

Checked on my new Hoyas today (I'm away at work for a fortnight and only got back today). The photo shows the way they were set up for while I'm away. It's our dry season and the irrigation comes on automatically twice a day, morning and evening. The drippers were turned down very low because it's the dormant period for these Hoyas, but at the same time I can't let them dry out completely.

As luck would have it while I was away we had what we call a "freeze" here, the minimum temperature got down to 10C one morning, which is about the absolute lowest we can get. That wasn't the real worry though. This cold air coming through is very dry and that isn't helpful. The nearest official weather station is about 5 kms from my place, but out on the flats whereas I'm back on a slight slope. My minimum temps are often a couple of degrees warmer than the weather station. But the humidity is much the same, and that morning it got down to about 13%.
