my potted jasmine under a perspex canopy suffers a great deal of leaf drop after turning yellow then brown, the conundrum is that it grows well with new shoots, its watered one gallon a week fed tomato feed once a fortnight is that ok?
Certainly too much fertiliser, I reckon, K 9. Mine, in a pot, gets a feed in spring and that's it. At most, you'd only fertilise every couple of months. I don't know what your temps are like but I'd be surprised if it needed a gallon of water a week either. Mine, in full sun, with temps in the mid-30s, is only watered every couple of days.
thanks for the advice italopile, its on a west facing patio in the north of england the prevailing winds tend to be n.w I wonder if that has a bearing,I shall change to your routine then see how it goes, thanks again!
