New Flush issue Cycas debaoensis


Corey Lee

Recommended Posts

Can anyone advise treatment for this issue?

Plant lost all its foliage about three years ago.  Didn't see any rot so left it alone and hope for the best.

A few weeks ago noticed new flush from around original plant but growing in a pale green with some brown dry spots.

Soil is South Florida sand and coral rock and what passes for topsoil here.  area drains well maybe too well.

You should use more Nitrogen in your fertiliser with a slow release effect  as 20-8-12 for example. 

I use Simplot's slow release Palm Plus 13/5/8 with micro's and have no problems with Cycas debaoensis at home (yellowing is on the old lower flush from last year).  I didn't fertilize at all this spring in my rental, and debaoensis did just fine there too, so perhaps it's not just a fertilizer issue.  I think my gardener's weedwhacker did a number on the one in Carlsbad.... that's why I don't own one or use one at home!

Fert and water will only go so far with these if they are in a high sun area, but that doesn't look like the issue in these pictures.
