Keeping a tree very healthy can help reduce or slow the inevitable, but is not a cure. Yes, there are some very promising research studies going on in Florida that are working on both a cure and a containment option. Two studies showing extreme promise are the development of resistant trees using gene-spicing (splicing in a Spinach gene that will make the cultivar resistant). That is slow, tedious work, and considering the number of citrus cultivars, you can expect to see the focus to be on commercial cultivars first, and who knows if it will ever expand to the lesser known, "hobby" cultivars (Dr. Steven Mirkov at Texas A&M). The other very promising research study is using a drug given for Gout in humans. That actually seems to kill the bacteria, and so far, appears to be safe for the trees, as well as for humans consuming the fruit. More research is ongoing with this study. I have posted links to both of those studies in the past on our forum. And lastly, the newest research study that is also showing extreme promise (I think the one you're referring to) is Dr. Sankra's study (U. of S. Florida) with nontechnolgy and product he has termed, "Zincide": http://www.huffingtonpost.com/2015/04/22/citrus-greening-treatment_n_7103984.html This is as exciting to me as the gout medication, as it is something us hobbyists could use to treat our existing and precious (and some rare) citrus trees. Amazing stuff going on, with enough monies finally being tossed in the ring to come up with some honest to goodness treatments. The bottom line for those folks in FL - you're going to still need to treat your treat several times a year with systemic Imidacloprid to protect against the ACP until some of these ideas come to fruition for the public. I would contact your local ag agency and follow their recommendations if you want to keep growing citrus in Fl for now. Patty S.

Miracle Gro is 24% nitrogen. I use it early Spring to get my roses off to a good start. They I alternate every other week. I water deeply the day before.

Silica, is it worth it to spray my indoor trees for foliar feeding? I’ve done it in the past, but have not the last couple of years. I have a whitefly infestation this year to my great horror (only in my sunroom), so I’m going to be spraying anyways...

wondering how people fertilize ... I’ve been foliar feeding my veggies with kelp, but will the hippie leaves absorb the spray? Would love to hear about fertilizing advice. TIA, Genez
