Many people plant hydrangeas in beds next to their homes or fences. This is because hydrangeas love the warm morning sun, but they dislike the heat of the afternoon. The best place to plant hydrangeas is in a sheltered location with sunny mornings and shady afternoons.
Little Lime® Hydrangea paniculata
One of the easiest types of hydrangeas you can grow along your home's foundation is a panicle hydrangea. Because their size ranges greatly, you'll want to be sure to read the label carefully when choosing which is the best fit.
A good rule of thumb is to calculate one and a half times the estimated maximum width of your Hydrangea and plant it at least that far from your house. And as always, you should take sun exposure into account.
Water regularly, and cover the root zone with an organic mulch to keep the soil moist at all times. Spacing varies with the type grown, but hydrangeas should usually be grown at least 5 feet (1.5m) apart.
Too much sun exposure can cause your hydrangea shrubs to burn on its leaves and blooms. Also, be sure to put your fingers in the soil to see if it needs watering. We do recommend a soak versus light watering each day, but you should be sure that the soil is always moist – not wet – by sticking your fingers in the dirt.
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.
Keep good air space between the plants; don't crowd them together or against other plants. Don't give bigleaf hydrangeas too much love; if they're too comfortable (water, fertilizer, etc.), they may devote all their foliage to leaves instead of blooms.
Hydrangeas grow well in gardens, but can also grow in pots. They need well draining soil that has a slightly acidic pH. If these are not the conditions in your garden, I urge you to try planting a hydrangea in a container.
Though they are fast growing shrubs, it can take 2-4 years for hydrangeas to reach their full size. Some are faster to mature than others. Growing hydrangeas is simple, and they can thrive in just about any climate.
Hydrangeas grow best in full sun (more than 6 hours sun) to part sun (4-6 hours sun). With that being said, all hydrangeas can handle some shade, but the timing and type of shade are important to consider. They can be in full shade during the hottest part of the day, as long as they are getting some morning sun.
Ficus trees, for example, have very aggressive root systems and even a small ficus tree planted close to a structure could cause foundation damage. Oaks and maples have massive root systems, but actually may cause less damage because their roots generally go around obstructions rather than through them.
E.g.: Small shrubs should be planted at least 2 feet from a house foundation, medium shrubs about 3 feet, and tall shrubs 4 to 5 feet away. An 8-foot shrub should be spaced about 7 feet away from a 6-foot shrub.
Laying gravel around the house as a foundation landscaping material helps ensure your foundation stays protected from outside elements. Along with its protective nature, gravel landscaping ideas and gravel provides a natural look that can be spruced up to fit your overall landscaping style and rock landscaping ideas.
Bigleaf hydrangeas, also known as hydrangea macrophylla, vary especially with some of the newer cultivars being bred to better tolerate heat and sun, but most of these including the mopheads and lacecaps prefer some shade, especially during the afternoon.
Just like Hydrangeas getting too much sun, a Hydrangea getting too much sun may develop wilting and yellowing leaves, even some brown spots.
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.
Can hydrangeas grow in full sun? Hydrangeas like morning sun, but do not do well if they're in direct, hot afternoon sun. Partial shade in the later parts of the day is ideal for these beauties.
To help Hydrangeas thrive, give plants a deep soak 1-3 times a week rather than giving them little sips of water daily. Hydrangeas do not tolerate overwatering or drought well. Their leaves wilt in the heat of midday, making it difficult to tell by appearance whether they need additional water or not.
Provide Some Shade
Most varieties of hydrangea prefer shade during the heat of the day. Most varieties of hydrangea prefer afternoon shade. If you think your hydrangea can benefit from a break from the sun you can purchase shade cloth online or from your local garden center.
Hydrangeas are long-lived shrubs, sometimes living for up to 50 years if properly cared for. They enjoy morning sun but afternoon shade, and they need frequent watering during the growing season. Prune them in the fall after the blooms fade so they can grow on strong stems the following summer.
Planting too close
The size of these shrubs will not be the size that the hydrangea will grow to. Hydrangeas can grow anywhere from two to six feet tall, and much taller if you are growing a climbing hydrangea. It might be difficult, but you will need to resist the urge to plant your hydrangeas too close together.
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.
