| g'day penny, better late than never maybe? but just in case you are still monitoring this thread. i ahve never used the liquid forms but i do use lots gypsum at planting times, i then follow this with lots of mulching, and find the plants handle the clay pretty well after that, in some cases you clay ph nay be too acid then you need to apply a little dolomite, you can have a ph test done for free at most nurseries, get your soil sample from about 6"s down. happy new year len |
