Hydrangea care tips Some... hydrangea varieties can bloom in both pink and blue. By using Pokon Hydrangea Blue Maker for these species in late summer, the acidity of the soil is influenced and the Hydrangea will bloom beautifully blue again the following year. Leave withered columbs on the plant as long as possible. The buds of a hydrangea are already formed in late summer. If these freeze, the plant will not bloom the following year. The withered umbels offer some protection. If the hydrangea is pruned too far, the hydrangea will not bloom the following year. Read more care tips in the Pokon Plant Guide. All hydrangeas need a soil that never dries out. In their natural environment they are forest plants, in fairly cool and misty valleys or along streams and rivers. The soil there is relatively acidic, so use Pokon Hydrangea Potting Soil Bio or Pokon Planting Soil Bio acid-loving plants when planting.
