How to Know When to Feed Acid-Loving Plants

Are your plants suffering from a long winter?

Popular plants such as azaleas, rhododendrons, blueberries, strawberries and heathers, are all acid-loving, meaning they need a soil pH of about 5.5.

Knowing whether your soil is acidic or not is the first step to healthier plants season after season.

If your leaves or needles take on a yellow-green hue, your soil is too alkaline is and this condition is called chlorotic. Plants become chlorotic when they cannot access important nutrients due to the soil’s high pH level. Plants that struggle for too long may lose leaves, branches and flowers. Left untreated for seasons, the plant could die.

Another sure sign of a high soil pH is if your hydrangea’s flowers are blooming pink.

However, it’s easy to correct the problem — simply lower the pH level and fertilize.

First, check your soil pH with a quick, DIY kit found at your local garden center. Grab a trowel of soil near your acid-loving plants and follow the kit’s directions.

Don’t worry. No matter what your pH is, fixing it can be easy.

If you have a soil pH higher than 5.5., add Espoma’s Organic Soil Acidifier to amend alkaline soil. If your soil has a number lower than 5.5., remedy with Garden Lime.

Save your coffee grounds, which are rich in nutrients and acidic, and sprinkle them lightly under your shrubs to help keep pH down.

Shredded leaves, sawdust, peat and pine needles also make great additions to your soil before planting. This decaying organic material will decrease the pH of the soil over time.

After you’ve identified and fixed your soil’s pH, it’s time to feed acid loving plants. Feeding them with Holly-tone in spring creates bigger blooms — and more of them. Feeding them again in the fall will ensure year-round health and beauty of your Acid-Loving plants.

Fertilize evergreens, like spruces, firs, hemlock and pines, to encourage a deep, healthy green color. Check out this video to learn more.

Fertilizing acid-loving plants only takes a few minutes, but creates bigger, better flowers and trees than ever before. You’ll be amazed by the results!

There are many plants that survive or thrive in low pH soils. Perhaps the most well-known acid-loving plant is the blueberry, which thrives in about 4.0 – 5.0 pH. However, strawberries and blackberries also favor acidic soil.

Each spring, begin your gardening with a simple pH test of your soil and plan your soil amendment around the results. Then, be sure to feed with Holly-tone spring and fall. Your rhodos, azaleas and camellias will thank you with bright-green leaves and huge, colorful blooms.
