To improve root aeration, it is necessary several times a year to loosen the soil surface around the bushes at a depth of 5 cm. Since the hydrangea is very moisture-loving plants, it should be watered every week, tree trunks need to mulch with peat or sawdust layer of which should be approximately6 cm.
