Early advice warned Belgian gardeners that pruning hydrangea or lavender in August would remove buds forming for the next season, leading to poor blooms. The guidance suggested limiting cuts to dead or damaged stems and advised timing pruning for late winter or early spring, depending on the plant.

A day later, French horticultural experts issued heat‑wave aftercare tips that reiterated the recommendation not to prune hydrangeas during August, noting that buds are already set beneath the foliage. The follow‑up added broader recommendations for orchid care after summer flowering and emphasized deep, infrequent watering to help plants recover from the heat.

Both updates highlight a consistent message across neighboring countries: avoid August pruning of hydrangeas to protect next‑year flowering, while focusing on watering and post‑bloom care for heat‑stressed plants.
