Hydrangea macrophylla; perhaps one of the best known garden plants. Originally from Japan these robust and reliable plants produce a truly amazing display in summer and autumn. Mathilda Gutges is an award winning mophead that is at its best in acid soil with blue flowers. As with most Hydrangeas the flower colour will be pink in alkaline soils and blue in acid soils, however Mathilda Gutges is so sensitive that it can have different colour flowers on the same plant. Ranging from dark pink to purple and blue! Treatment with bluing agent can help produce blue flowers however this is much more successful in pots than in the borders. Very easy to grow; it can be grown in the garden or in a pot or container. In containers use a good quality John Innes compost as this plant will be there a long time and peaty types of compost eventually degrade; become too packed and choke the roots. Ensure you feed regularly as a hungry plant is a poor performer. We recommend Osmoscote pro 8-9 month applied in the early spring. One application gives all the nutrients the plant requires for the whole year. John Innes is a soils based compost.A vigorous grower that will need pruning. After flowering prune back to close to the old wood. If the plant becomes too large a more drastic pruning can be undertaken!
