Taking Care Of Nikko Blue Hydrangea

Lead Image

The Nikko Blue Hydrangea bush grows 3 to 6 feet in height and 6 to 10 feet in width. It's a bright blue flower that grows in clumps and does well in moist, well-drained soil. Planting in full sun to partial shade is acceptable. It's frost tolerant and blooms in the late spring and early summer months. Its most popular uses are in beds and borders, containers, and as a cut flower.

Plant Maintenance

The plant needs to be pruned at the end of each growing season, as the next season's buds grow off of the previous season’s flowerings. Cut the stem right above the bud for the best results.

Hydrangeas like water. The leaves tend to droop and might get brown spots on the tips if they're not receiving enough water. If they're a bit droopy at night but perk up by the next day then it should be okay. Any more than that and you should increase the water.

Controlling the Color

You can also somewhat control the color of your Hydrangea. If you want a bright blue flower then it's best to keep the soil acidic (coffee grounds and shredded grapefruit peels work well). If you lower the amount of acid in the soil, then your blooms will be more of a light pink color.

With proper care and knowledge of how the hydrangea reacts to different acidity levels, you can keep them flowering year after year.
