Rising summer temperatures and dry soil conditions at RHS Wisley have prompted talks of moving hydrangea collections to cooler, moister northern gardens. However, with the right care and plant choices, southern gardeners need not give up on these popular blooms.
- Hydrangeas prefer light shade and moist soil, struggling in hot, dry conditions.
- RHS Wisley may move hydrangea collections to its northern gardens for better growing conditions.
- Certain varieties like Hydrangea paniculata are more heat-tolerant and suitable for warmer areas.
What happened
Due to increasingly hot summers and dry, sandy soil at RHS Wisley, the Royal Horticultural Society is considering relocating its significant hydrangea collections to its cooler, moister gardens in northern England. This move aims to reduce the intensive care needed during heatwaves and drought, ensuring the plants thrive with less intervention.
The decision reflects changing climatic patterns affecting traditional gardening areas. Hydrangeas, normally woodland plants that favor light shade and damp soil, are vulnerable when exposed to prolonged heat and dryness, which have become more common in southern regions during recent summers.
Why it feels good
Despite the relocation plans, gardening experts are optimistic that hydrangeas can still thrive in the south with mindful care. Gardeners are encouraged to plant hardy varieties such as Hydrangea paniculata, which shows better resilience to heat and dry spells, making it a good match for warmer climates.
Seasonal adjustments like providing light shade, regular watering, mulching to preserve moisture, and using liquid fertilisers can greatly improve plant health during the hotter months. With these practices, hydrangea lovers in southern gardens can continue enjoying vibrant blooms as the seasons cool.
What to enjoy or watch next
For gardeners looking to update or expand their hydrangeas, varieties such as Hydrangea paniculata ‘Vanilla Fraise’ and Hydrangea serrata ‘Bluebird’ are recommended for their toughness and beautiful flower colors. Potted hydrangeas are especially convenient as they can be moved to shadier spots during heatwaves.
As the seasons transition from summer to autumn, conditions naturally improve for hydrangeas with cooler nights and increased dew. Continuing attentive care through the rest of the year can help these plants recover and prepare for another season of flourishing growth.
