  • 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.
