Yellow Leaves / Soil pH
Hi all, first time poster...I've been browsing this site for a while and have been really enjoying the fantastic information available especially for us gardening newbs!
Anyway, i am growing a variety including C. Genovese, Amish P, J. Flamme, CP and Grosse Lisse. They have been growing well and have set fruit however just in the last couple of weeks I've noticed a yellowing of the lower leaves, but its starting to work its way up the plants....the new growth looks healthy. Yesterday i purchased a pH test kit and took a number of samples and it appears my soil is rather alkaline (7.5 - 8.0).
So could the yellowing be a result of the high pH? I've read that sulpur can reduce pH however is this immediate or will it take time......are my plants doomed :(?
Thanking you all in advance!
