bigleaf hydrangea

When watering Bigleaf Hydrangea (Hydrangea macrophylla 'Otaksa'), be sure to have moist soil but not overly saturated. These plants prefer soil that is kept consistently moist but not soggy. Water deeply once a week during the summer months and less in the winter months. Water the base of the plant near the stem rather than from above to avoid wetting the leaves. Depending on the weather, you may need to provide more water, especially during dry and hot spells. Make sure to check the soil before watering to avoid overwatering.

Bigleaf Hydrangea (Hydrangea macrophylla 'Otaksa') grows best in full sun, meaning it needs at least 6 hours of direct sunlight per day. However, it is important to note that too much sun can cause the leaves to curl and become dry. This species of Hydrangea can survive in partial shade, but the more sun it receives the better it will thrive and produce better blooms. Bigleaf Hydrangeas typically flower best in full sunshine during the summer months. It is important to note that too much direct sunlight in winter months can be damaging, so late afternoon shade is recommended during colder seasons.

Bigleaf hydrangea (Hydrangea macrophylla 'Otaksa') should be pruned twice a year, once in late winter and again in midsummer. Late winter pruning should only be done to remove damaged, dead, or diseased wood, and should not involve significant trimming. Midsummer pruning should be depended on the shrub’s size and shape, so it is best to prune lightly, removing only old wood, dead branches, and individual flower heads. Try to avoid cutting back to the same point twice in the same season. Pruning the Bigleaf hydrangea too heavily can reduce the number of flowers produced for the following year.
