Hi all,
I've had no luck with Siver Saw Palmetto at all. I buy them at a decent size, but within 12-18 months of planting out, they go yellow on me...lowest frond first and within 4 months or so, eventually dies. They have been grown locally, and are a nice green when I buy them. I tried one about 2-3 years ago - with the same result. Bought this one and placed in the ground about 12 months ago. The nursery owner had about 6 or 7 of them, and mentioned he gave them no special care.
I've tried treating them with: Iron Sulphate, Mag Sulphate, Iron Chelates, Miracle-Gro ... but there has been no noticable improvement...in fact it is declining more rapidly. I water this palm moderately twice a day (usually), as I know they grow in swampy soil in their native Florida. The soil here is fairly sandy, with manure and other organic additions. It's in a full-sun location.
I just don't know.... I think I'm gunna rip it out and replace it with the potted triangle palm in the left of picture.
Frustrated .. maybe it's a soil issue...a pH issue... maybe it's just one of those species I cannot grow...and I can accept that.
Any thoughts/suggestions gratefully received !
Best regards
Michael.
