Sun, just the right amount of sun, is essential to a successful container garden. We live in an apartment that does not get southern exposure, and the western exposure we get is HOT, quite hot, from about 1pm each day through 6pm. Watering plants in the early am hours here does not work. Also keeping houseplants thriving without southern exposure can be quite a challenge. I have fifteen African violets that I move around in our bedroom to catch the sun from the west, and then as it creeps around the side of the building I have a shelf in my office loaded with succulents and cactus plants, not to mention my husband’s ever growing bonsai collection, trying to catch the last rays of sun before it disappears for another day. Lots to keep up with. I’ve killed way more than I’ve saved but this year I’ve actually had some much appreciated success.
