To get big flowers from bigleaf hydrangeas (Hydrangea macrophylla), you need to give them the right care, prune them, and choose the right type.
How to Get Big Flowers from Bigleaf Hydrangeas
You will be able to purchase those beautiful flowers if you pay attention to the guidance that is presented in this article:
1. Pick the Correct Type
Not all bigleaf hydrangeas have flowers of the same size, according to the species. Make sure to pick varieties that are well-known for having large blossoms, such as
2. Where to Plant
Sun: Bigleaf hydrangeas do best when they get some morning sun and afternoon shade. Too much sun can burn the leaves and make flowers less likely to grow.
3. Getting the soil ready
Change the Soil: Add organic matter to the soil, like compost or manure that has been broken down. This makes it easier for plants to get nutrients and strengthens the soil.
Levels of pH: The pH of the soil can change the color of bigleaf hydrangea flowers. It’s best to keep the pH below 6.0 for blue flowers. Keep the pH above 6.0 to get pink blooms. You can change the pH by adding lime (to raise it) or sulfur (to lower it).

4. Watering
Regular Watering: Hydrangeas need to be watered often, especially when it’s dry outside. Aim for about an inch of water per week, making sure the soil stays damp but not soaked.
5. Getting fertilized
Use a Balanced Fertilizer: When new growth starts in the early spring, use a balanced, slow-release fertilizer. To get more flowers, look for one with a higher middle number (phosphorus).
6. Cutting back
It’s important to know when to prune bigleaf hydrangeas. They usually bloom on old wood, so do it right after they finish blooming in late summer or early fall. This lets flower buds form on new growth for the next season.
7. Putting down mulch
Apply Mulch: Wrap organic mulch around the base of the plant to keep the soil wet, keep weeds away, and keep the soil’s temperature stable. It only needs about two to three inches of mulch.
8. Dealing with pests and diseases
Watch Out for bugs: Look out for aphids, spider mites, and other bugs. Use soap or neem oil that kills bugs right away to get rid of them.
Keep diseases away: Making sure plants get enough water and air flow can help keep problems like powdery mildew at bay.
9. Safety in the winter
Winter Care: If you live in a cold area, keep your hydrangeas safe from strong winds and freezing weather. Cover the plant’s base with mulch, and if you need to, wrap it in cloth.
