I have had past problems with my container plants drying out,
evaporation, over the last few years with this hot weather & with having to work during the day. I have tried the gel stuff etc but not much improvement.
This year I found a tubing unit that slips down the side of my bell pots & tubs. I tried one in each of them and I am highly delight with the outcome, plants have kept healthy (with an edge over the others). You water the topas normal and into the tube and this gets water to the lower part of the root system, simple but clever the tube allows water through the side of the tube not out th bottom.
Just like to share this with you all, I'm getting some more as xmas presents from the grandchildren...
