I grow fuzzy kiwi in north Florida (zone , Vincent and Tomuri varieties. I also have the smooth artic kiwi.  We usually get over 600 chill hours and this winter was real cold, we had low temps of 12 degrees on two mornings. Everything did fine and budded out by mid march.  Hoping for fruit this summer, they've been in the ground about four years now.

Bushel Stop locations in Broward carry pine bark fines.  I think i paid $6 per 2 cut ft bag.  Also home depot on Atlantic Blvd in Coral Springs sells large bags of perlite and vermiculture.
