For the most part, hydrangeas can be planted any time during the growing season, provided the person planting them will be around during the hottest part of the year to monitor them for water needs and other possible stresses.
Fall is the best season to plant hydrangeas, followed by early spring. The idea is to give the shrub plenty of time to establish a healthy root system before blooming. The best time of day to plant is early morning or late afternoon.
They can be planted at any time of the year. However, to get good results, keep these considerations in mind: Whenever possible, plant in early summer or fall. Don't plant in early spring when frosts are still possible.
This timing will vary by region. For instance, in areas with winter freezing and snow, hydrangeas should be planted in early spring or early fall (as soon as summer heat breaks). In warmer regions with mild winters, the window for planting hydrangeas is longer, from fall all the way through to early spring.
While you can plant hydrangeas at any time, the best time is spring or fall. If you plant in the middle of the summer, they're going to need lots of attention to survive. Place and Plant. Once you've found the perfect spot (ideally with well-draining soil,) dig a hole twice the width of the hydrangea's container.
The months of both spring and fall are best for planting hydrangeas, so long as the weather is mild. In spring, this should be after frost season, and in fall, before it begins again. If you need to plant in other months, avoid those that are very hot or very cold.
In the spring, I suggest getting them in the ground before the end of June. In the fall I suggest planting in September or October. Once the frost begins to set in your hydrangea will not have ample time to take up water and get comfortable in its new home before going dormant.
Hydrangeas do not require strict reqular pruning; simply keep them healthy by removing dead wood and they will grow and flower well.
Most common hydrangeas prefer a partial sun location - ideally receiving sun in the morning hours and shade in the afternoon. The reblooming Endless Summer® Hydrangea series prefers part shade.
Adding organic materials, such as our Coco-Fiber Potting Medium and compost will improve most every soil type. Organic materials bind sandy soil particles so they retain moisture and nutrients better. They also break apart clay and silt particles, so that water can infiltrate and roots can spread.
It takes perennials years to reach maturity,' says Standard. Depending on the type of hydrangea you have, it can take 2-5 years to bloom after it's planted. If your hydrangea gets plenty of sun, and it's at least a few years old, it's time to look further into the reason it isn't blooming.
Where to plant hydrangeas. Hydrangeas do best in moist, well-drained soil and dappled shade – not too sunny and not too shady. Avoid south-facing positions, especially if the soil is very dry. For a very shaded spot, such as a north-facing wall, grow the climbing hydrangea Hydrangea anomala subsp.
Put the pot in a spot that is away from any direct sunlight and keep the soil slightly damp. In two to four weeks, a root system should begin to develop. You can transplant the cutting so that it can have the winter to establish a strong root system.
As rapid growers—averaging about 2 feet of growth per year—larger varieties of hydrangeas can reach up to 15 feet tall. Applicable in growing zones 3 to 9, hydrangeas are a low maintenance plant that will return year after year with proper care.
A newly planted bush may bloom the first year if it set flower buds while it was confined to a pot, and then not bloom again for a year or two as it settles into the soil in its new location. Instead it is busy growing new roots and branches, instead of flower buds.
Water your hydrangeas in the morning before the heat of the sun is strong enough to quickly evaporate soil moisture. Try to avoid watering at night, which can encourage mold and mildew as the moisture sits through the cool night. Water your hydrangeas through the growing season as well as in late fall.
Most hydrangeas prefer only morning sun. Yet one type of hydrangea can soak up the sun all day: the panicle hydrangea. While they can stand the sun, these do just fine in partial shade, too. Plus, panicle hydrangeas are the hardiest hydrangeas.
Some gardeners report success in turning their hydrangeas blue by applying coffee grounds to the soil. The coffee grounds make the soil more acidic, allowing the hydrangea to more easily absorb aluminum. In addition, fruit peels, lawn clippings, peat moss and pine needles, are thought to have a similar effect.
Many people think that you need a shady garden in order to grow hydrangeas. While that is true for some varieties, some hydrangeas thrive in sunny spots and even need full sun to develop into the fullest plants and the brightest blooms.
Wrap with winter protection.
During the winter, make a DIY A-frame wire cage out of burlap and chicken wire to protect your hydrangea plant. This cage will protect it from winter winds, heavy snowfall, and cold temperatures.
If you don't prune hydrangeas then they can eventually resemble a tangled mass of woody stems, and the flowers will become smaller and less showy.
Deadheading hydrangeas is not a crucial task, and will not damage your plant if you do not do it. In fact, many gardeners find that the dead flowerheads can provide interest in the winter garden, particularly on frosty days, and can also provide winter protection for the plant.
To prepare hydrangeas for winter in colder areas, add a thick layer of mulch around the base of the plants to protect the crown and roots from freezing temperatures.
