peat-Lite Mix* is formulated for growing topical
plants. The Foliage Plant
Mix ** and the Epiphytic
Mix** formulas are adapted specifically for
their respective plant types and are modifications
of the original peat-lite mix.
Cornell has used Osmocote 14-14-14
and Peters 14-7-7 fertilizers with the tropical
plant mixes with good results. Other fertilizers
are omitted with the exception of dolomitic limestone
and 20 per cent superphosphate which are added
to adjust the pH and to maintain adequate phosphorus
levels. A trace element mix is added to assure
a balance of minor elements. Trace element mixes
can be purchased from specialty gardening centers.
