Hydrangea: planting, maintenance, care. The best time to plant hydrangea is during mild spring or possibly in autumn.
The most resistant species can withstand temperatures down to -20°C. Hydrangea thrives in organic-rich, cool, well-drained soil. This combination ensures abundant flowering and vibrant colors. In clumps, maintain the clumps by maintaining the different plants in clumps. The different varieties of hydranges lend themselves easily to landscaping. As a flowering hedge, they combine intimacy and aesthetics.
