Hydrangeas, with their extravagant blooms, are a quintessential part of any garden. However, coaxing the best performance from these plants requires more than just basic gardening skills. This guide will share some secret Master Gardener’s Tricks to Grow the Successful Hydrangeas!
The soil pH directly affects the hue of hydrangea flowers. Acidic soil (pH less than 7) leads to blue hydrangeas, while alkaline soil (pH above 7) produces pink ones.
To manipulate the color, adjust the soil pH slowly and cautiously using aluminum sulfate for acidification or garden lime for alkalinization. Start this treatment in the early stages of plant growth to avoid any sudden shock.
Mulching is crucial for maintaining soil moisture, moderating soil temperature, and reducing weed competition. Organic mulches like pine needles or shredded leaves also enrich the soil by adding nutrients as they decompose.
In addition, amendments like coffee grounds can be beneficial for their nitrogen content, promoting healthier leaf growth and lowering soil pH. Crushed eggshells, high in calcium, help in strengthening cell walls, improving overall plant health.
Recognizing the hydrangea type is fundamental to successful pruning. For Bigleaf, Oakleaf, Mountain, and Climbing hydrangeas that bloom on old wood, prune them soon after they’ve finished blooming.
Conversely, Smooth and Panicle hydrangeas bloom on new wood, so these should be pruned in late winter or early spring, prior to the emergence of new shoots.
Fertilizing hydrangeas with a phosphorus-heavy product encourages blossoming. An NPK ratio where the middle number is highest, such as 10-30-10, is ideal.
Apply this specialized fertilizer in early spring when the plants start to break dormancy, then again
