Growing Hoya linearis Part Three

The problem that I found with the bonsai mix was that it was very difficult to tell when to water. The mix is hard, sharp and difficult or impossible to put your finger into to test for dampness. It is also heavy, which throws off my ability to test for dryness, by hefting the pot. It seemed that water pretty much poured right through it, but I settled on a weekly watering routine just by guess work.
