Nov-AprilBlue Hydrangea - Hydrangea Macrophylla
Blue hydrangeas are your go-to choice for elegant flowering shrubs and when shopping for a garden flower with old-fashioned charm. They are easy to cultivate, grow in almost any soil, and produce abundant dinnerplate-size blue snowball blooms throughout the warm season and into autumn.
How to Grow Blue Hydrangeas
Hydrangeas, typically considered as shrubs, are easy to cultivate. Although they tend to grow to be large bushes and seem like a tough job, they practically grow themselves. The hydrangeas grow quickly and mature to 15 feet high and 10 feet wide.
Blue Hydrangea Planting Season
Since hydrangeas are relatively large shrubs, giving them enough time to develop a healthy root is essential. This is why it is wise to plant hydrangeas in spring or fall.
If you plan to plant the shrub, it is advisable to do so during the much cooler times of the day. Mornings are especially suitable for protecting the hydrangeas against heat stress.
Where to Plant
The best place to plant your shrubs is along the fence, near home, or as a border. They can be grown in direct and open sunlight or filtered shade, making them a favorite for many homeowners who do not have the "perfect" solution for many flowering shrubs.
Growing them along the fence clears them from the harsh afternoon heat. They are perennials that often thrive in hardiness zones 3 to 7.
Soil Recommendations
As revealed above, they can withstand almost any soil type. They thrive in soil rich in organic materials, and the ground should also have good drainage since the hydrangeas grow well in moist soil. However, the shrubs are intolerant to waterlogged soil because the roots tend to rot quickly. To improve soil quality, prepare your soil using a mixture of abundant compost before planting.
Blooming Season
They have varied blooming seasons, depending on the planting zone and the cultivar. Most bud from mid-spring to early summer. In hot regions, these shrubs stop budding in summer due to the heat intensity and bloom again in the fall.
How to Control the Blooming Color
are unique plants in that you can control their colors. However, not all hydrangeas can withstand color adjustments. If you want to increase the strength of the color of your shrubs, you need to lower your soil’s pH levels. By reducing the soil’s pH, the hydrangeas can absorb enough aluminum from the ground, thus giving them a beautiful blue color.
Fertilizer and Care
Adding peat moss or sulfur to the soil can lower the PH level. You can add aluminum sulfate throughout the growing season to make them shinier. Indoor Cultivation: If you want to grow them inside your house in a pot, choose a non-porous container about 18 inches wide to accommodate the plants’ maturity size.
A non-porous container or pot helps retain the moisture needed for the Blue Hydrangea to mature. It would be best if you also created drainage holes to allow the proper drainage of the excess water.

Care
Blue hydrangeas thrive in well-drained, moist soil with a slightly acidic pH. It's important to regularly water them to keep the soil moist, especially during dry spells. After they bloom, prune them to maintain their shape and promote new growth. In the spring, be sure to fertilize them to encourage vibrant blooms.
Plant Reproduction
Blue Hydrangea spreads through underground rhizomes and root ball division.
Plant bare-root shrubs during the more excellent spring or fall months, from November through April. Dig a hole twice as wide as the root system and slightly more profound than its height. Position the shrub so that the top of the roots is level with the ground, and put back the soil dug over the roots. Apply a 2-3 inch layer of mulch around the base to retain moisture and suppress weeds, ensuring the mulch does not touch the shrub's stem. Water regularly, especially during the first year, to establish strong roots. Prune shrubs as needed to promote healthy growth. In the spring, fertilize with a balanced, slow-release fertilizer suited to the specific needs of the shrub.
