Challenges With Late-Blooming Plants:
1. STAKING or HEADING BACK: Chrysanthemums (hardy mums), Asters, Phlox paniculata (garden phlox), Nipponanthemum nipponicum (Montauk daisy), and other late-season perennials need pinching back before early July. The extent to which this is done can vary from a conservative tip-out to a more drastic cutting back by one-third to one-half. The Anglophiles among us may know this as the “Chelsea Chop,” in reference to the Chelsea Flower Show, which is held in late spring each year. It’s important to provide support for some of the tall growing perennials early in the season to allow them to grow into your staking system. Bamboo stakes and jute twine are probably the most straightforward approach, but peony hoops and tomato cages can be very effective as well. Staking may seem a little fussy and early in the season, but you’ll be glad you did when the late season storms return.
2. DROUGHT: Irrigation requires constant monitoring, and gardens often require supplemental water during long dry spells. Over the course of the gardening year, any number of things can happen to disturb a basic irrigation system: from root blockage to punctured lines.
3. HERBIVORY: Across the island, it seems that few gardeners are safe from the animals who would make your garden their dinner. From deer to rabbits and chipmunks to avians, there is no shortage of hungry animals as wild habitats are consumed by new development. Regular applications of Bobbex can help dissuade deer from browsing your plants, but I have heard many reports that rabbits are unfazed by the stench and continue munching. For bunny damage, I recommend hot pepper wax (capsaicin), available as a spray and applied regularly to lower growing plants. In areas where repellants fall short, physical barriers such as caging and fencing are the best options. Sorry, up-islanders, I’m talking to you.
4. CATEPILLARS (and other insects): Many native plants play host to the caterpillar larvae of some fantastic moths and butterflies. Considering this, I always recommend doing some research before impulsively reaching for insecticide. If the damage isn’t widespread, I urge you to accept this as a sign that your garden is a part of the wider ecosystem, which is surely something to celebrate! If treatment is necessary, organic options such as Safer Soap, Neem Oil, Pyrethrum, or Bt are best.
