panicle hydrangea

Panicle hydrangea requires medium amounts of water and should be watered deeply and evenly, typically once or twice a week. Water thoroughly, making sure the soil is moist but not soggy; water at the base of the shrub, not on the leaves. In general, hydrangeas need approximately 1" of water each week when planted outdoors, including rainfall. During periods of hot, dry weather, the plants may require more frequent watering. During winter months, water only when the soil is dry.

Panicle hydrangeas (Hydrangea paniculata 'White Moth') prefer to be grown in full sunlight, about 6 to 8 hours of direct sunlight a day. They can tolerate partial shade, but for the healthiest blooms and brightest colour, it's best to give them all the sun you can. To help it retain moisture, you can also mulch around it in spring. Make sure to avoid over-watering and fertilising and to allow the soil to dry out between watering. By providing the right amount of sun and water, this plant can produce beautiful, fragrant white blooms for many years to come.

Panicle hydrangeas, or Hydrangea paniculata 'White Moth', should be pruned in late winter or early spring. For the most part, panicle hydrangeas should only be lightly pruned. Thin the branches and remove dead flowers. If the shrub is overgrown, you can lightly prune about 1-third of the old growth, which will allow new growth to fill in and compact the shape of the shrub. When pruning, do not cut back into the older wood, as this will not produce new blooms.
