hi,
x-posted -- what causes sap production (there are sap drops at the
leaves' bases (where the stem (?) attaches to the leaf))
this has been occurring since summer 2004 these are indoor plants
(tropical hibiscus) (no relation to h2o, food, light, humidity, soil, no
pests, etc...)
plants eventually lose all leaves and die
so would like to know what stimulates sap production to troubleshoot
tia
