Lime can be used to change the pH of the soil, making it more alkaline, which will help to produce pink flowers. Let’s look at lime on hydrangeas. We’ll discuss how to make hydrangeas produce beautiful pink blooms by using lime as a soil amendment.
Lime on hydrangeas
To use lime as a soil amendment for your hydrangeas, simply apply it to the ground around the plants according to the package directions. In most cases, you’ll need about 3tbsp of lime for two or three hydrangea plants. You’ll likely need to reapply lime every year or two to maintain the desired pH level.
Before adding lime or any other amendment to the soil, it’s a good idea to test the soil’s pH range. You can buy a soil test from your local garden center. To grow pink hydrangeas, you’ll need alkaline soil with a pH range of between 6.5 and 7.0. Lime can be used to increase soil pH, making it more alkaline.
Granulated or liquid lime can be purchased from a garden center and can be mixed into the soil before planting hydrangeas. If you want to add lime to an existing plant, you can sprinkle the granules around the base of the plant and carefully mix it in with a trowel or rake. Be careful not to damage the plant’s roots when doing this job.
Alternately you can sprinkle lime on the topsoil and water it in, then add a layer of mulch. Lime granules are a great way to slowly release lime into the soil throughout the growing season.
If you are growing a hydrangea as a house plant, you can buy liquid lime or dissolve the granules in water before feeding it to your plant. Add 1 tbsp of lime to a gallon of water and use this to water your plants.
The benefits of adding lime to soil
In addition to changing the color of your hydrangeas’ blooms, adding lime to the soil can also help to increase drainage and reduce the chances of fungal diseases.
- It helps to increase the soils pH range, making it more alkaline
- Enables you to grow pinker hydrangeas
- It can be beneficial to the drainage of the soil
- It helps improve the health of plants such as hydrangeas that require alkaline soil to thrive.
- Reduces the change of plants developing fungal infections
- Lime can also be used to neutralize soil that is too acidic for growing hydrangeas or other plants.
Final thoughts
As you can see, lime is very beneficial for growing hydrangeas and changing the soil’s pH range in your garden. Adding lime can help you grow beautiful pink hydrangeas. Before applying lime to your plant’s soil, it’s a good idea to do a soil test to check the pH range. Hydrangeas require alkaline soil with a pH range of between 6.5 and 7.0.
