Hydrangeas do not like to dry out. In dry weather, if your plant wilts, soak the roots with a hose and the plant will usually recover, and in any case, water regularly until plants are fully established.

Care Guide

Planting Advice for Hydrangea Incrediball:

• Really low maintenance, Incrediball prefers compost-enriched soil that stays moist. It can be planted in sun or light shade.
• Shrub roots generally tend to spread out rather than down, so dig a planting hole 3 x wider than the roots of the shrub you’re planting and mix some well-rotted compost or manure with the soil from the hole and use this to re-fill one the shrub is in place.
• We’ve found that a square hole is better than a round one as the new roots, once they reach the edges tend to grow in a circle round the circumference of the hole whereas when they reach the corners of a square hole, they find it easier to grow through.
• Before planting soak container-grown shrubs thoroughly and allow to drain.
• Remove the plant from its pot and tease out a few of the roots.
• Add Mycorrhizal fungi to the roots when planting to help plants establish quicker.
• Place your shrub in the hole at the same level at the pot.
• Refill the hole with the earth removed (backfilling) and firm in the soil with your heel, avoiding the root ball, then water well.
• Mulch around the base of the plant with a collar, compost, gravel, bark etc.
• If you’re planting into pots, place some old rocks, stones or gravel in the bottom of the pot for drainage and ballast. Use the best compost you can buy and some sand or grit for drainage.
