In late July, gardeners were urged to monitor soil moisture at 15–20 cm, use deep-watering methods, and provide temporary shade to protect hydrangeas and daisies from wilting. Follow-up guidance included adjusting soil pH for blue hydrangea blooms, using drought-tolerant perennials like Monarda or Californian lilac, and applying organic mulch to conserve moisture. During heat waves above 30 °C, gardeners were advised to perform cambium tests to check for plant recovery and to avoid heavy pruning of hydrangeas to protect existing buds. Recent updates expand care recommendations to include roses, suggesting ~~'deadheading'~~ ‘deadheading’ faded flowers to encourage new blooms while cautioning against improper pruning that leaves dead wood. For pest management, natural alternatives such as black soap sprays and nettle manure are recommended for controlling aphids. To support local wildlife, gardeners are advised against trimming laurel hedges into straight walls, which can destroy bird nests, and should transition robin feeders to low-level platforms to mimic natural foraging. Regarding water management, particularly in France, private well owners must declare their installations to local town halls, noting that even private extraction may be restricted by prefectural decrees during droughts. Newer guidance addresses specific hydrangea heat stress. Strong sunlight can cause leaf burn, characterized by brown, dry patches; protection via shade and deep, infrequent watering—ideally early in the morning or after sunset—is recommended. Gardeners are cautioned that midday drooping may be a natural response to limit water loss through stomata rather than a sign of thirst, provided the soil remains cool and damp. However, wilting in moist soil may indicate root rot from overwatering or root overheating. To prevent damage, gardeners should manually check soil moisture at 5–10 cm rather than following a strict schedule.
