Stake and Support Top-Heavy Bloomers
Tall annuals and perennials—like hollyhocks (Alcea rosea, native to Asia and naturalized but not overly invasive) and delphiniums (Delphinium spp., native to Europe and Asia, non-invasive)—often start to lean under the weight of burgeoning blossoms. Install stakes or tomato cages now to avoid broken stems later. I learned this after a storm snapped several of my sunset hyssop plants!
A sturdy support system also prevents buds from resting on damp soil where fungal spores lurk. Better posture means more impressive flower displays and less time spent corraling floppy stems mid-season!
