- Garden Performance
Double Cascades are a Grandiflora doubles
that are covered with huge blooms all season. They
have a mounded upright habit, contrary to their
name! Best suited to the garden, they also look
good in containers either alone or in
combinations.
- Growing
Guide
As with all petunias occasional pruning will
rejuvenate the plant. The carnation-like flowers
hold up well in inclement weather. Fertilizer:
A moderate feeder. Use any all purpose
fertilizer, compost, etc. For small
containers, should yellow leaves develop in
spite of regular feeding, apply 'chelated'
iron (available at all garden centres where
fertilizer is sold), at the labeled rate every
three weeks. This will lower the pH which is
what petunias need.
Water only when the
top of the soil feels dry.
