I have looked, but not found any info regarding this in the forums. I have recently planted hybrid grape vines in Oil-Dri in large pots with the addition of a slow release 10-10-10 fertilizer and bit of store bought compost with a guaranteed analysis. The vines are being rather laid back about pushing out buds. There is activity, but a bit slow. Any cautions or suggestions?
Cat litter? More conventional growing media (other than dirt) are usually peat/perlite/sand mixtures. Grapes like to be well drained and they need to have oxygen at the roots. I suspect this clay like material won't have a lot of air spaces in it after it has been watered. Ralph
It depends on the type of clay. Some (turface, dryz-it, etc) are bake in a way that they stand up very well under container conditions. A sort of "poor man's akadama" if you will. Very popular with bonsai. Others, however, are not baked in this way. They do turn to much. I just don't happen to know which oil-dry qualifies as. It's the difference between growing in perlite or oatmeal. How long is ago is recently? Dig your finger down into the pot as far as it goes. What do you feel? Michael
Actually, I chose Oil-Dri (premium) because it is essentially a seramis/turface substitute. I forgot to mention I added about 1/3 perlite by volume. The granules appear to be holding their structure nicely, but I'll watch them closely. Thank you.
