south FL growers...
 

... can you help?

I'm growing on a really chalky soil, not unlike south Florida's Oolitic limestone, just much softer and chalkier. Any ideas on a fertiliser or soil improver to counteract the lime, which can lead to yellowing of the leaves.
I've got about 18" of soil before I hit pure chalk in which next to nothing grows, even the tree roots just turn sharply when they hit it.

P.S. send some sunshine over, too its been raining for days. :08:

My soil is all sand, as deep as I can dig! I'm sorry I can't help with your question, maybe someone else has a similar type soil.

Raised bed? Plenty of compost? Coffee beans? Dig huge planting holes, drill through it perhaps. It will probably require a lot of work or you will just need to live with it! Hope somebody has better ideas, its frustrating. I throw out buckets of rocks each month here from when I did new plants or move things around.
