Because they bloom for six months out of the year and are reasonably simple to grow in containers, inside, or outdoors, hydrangeas are almost the ideal plant.
They are reasonably priced and available at practically all local nurseries as well as food stores like Trader Joe’s.
The flowers may be quite spectacular even when they are not in bloom due to their rich green foliage.
Where to Plant Hydrangeas
Location is important since too much sun might cause a plant to struggle and produce feeble blooms. The majority of hydrangeas prefer early sun, though they may tolerate more sun the closer you are to the Southern California coast. Even in San Diego, inland homes benefit most from being located in a north- or east-facing location to shield them from excessive sunshine. The blossoms of hydrangeas will struggle in deep shadow, and isn’t that the point?
In pots, hydrangeas can also flourish, but you’ll need to take extra precautions to prevent water from draining away. Put your finger into the pot about two inches down as a general rule of thumb. If the soil is dry, more water should be added. The soil should be damp but not soggy. Twice during the growing season, fertilize them.
Caring for Hydrangeas
It should come as no surprise that these lovely plants adore water as the name “hydrangea” is derived from the Greek word “hydro, meaning water. Water is the essential to keeping these plants blossoming happily, so make sure there is appropriate irrigation where you put them. Avoid overwatering and keep the ground cool by using mulch.
Another thing to be careful with is pruning. Like many other flowers, deadheading (removing dead flowers) hydrangeas encourages the growth of additional blooms. Simply remove dead branches and blooms when pruning, as cutting off only old wood may also remove bulbs intended to bloom in the upcoming season. For for this reason, some advise against pruning hydrangeas at all in the fall, winter, or spring. If you have a new plant that is little and possibly unfamiliar to your gardener, they may yank it out believing it is dead because hydrangeas are actually deciduous and lose their leaves in the winter (been there). With the exception of one kind known as oak leaf hydrangea, which has leaves that resemble the colors of the fall, they will appear somewhat sickly.
Consider growing hydrangeas in pots and bringing them inside during periods of really cold weather if you happen to live somewhere where it snows (yep, it snows even in inland San Diego). Otherwise, make sure that mulch is used to protect the roots.
Mopheads or Lacecaps?
Mopheads and lacecaps are the two categories into which hydrangeas are typically divided. Typically, mophead hydrangeas have spherical clusters of beautiful blue, pink, or white flowers. Although certain mopheads in Southern California bloom sporadically all year long, the majority of them bloom in the late spring and summer. Mophead flowers have a maximum diameter of 14 inches!
The core of lacecaps (shown above), which have tiny flowers, appears to be flat and empty. Additionally, there are numerous species and variants among the two groupings. The colors of the leaves can also vary.
Changing Color of Hydrangeas
Although it’s quite simple to find either blue or pink mophead hydrangeas in Southern California, you can also enhance the color tones by changing pink to blue and blue to pink.
The pH of the soil is fairly easily adjusted to do this. But white mophead flowers don’t work with this method.
The amount of aluminum that is available to plants depends on the soil pH. Mophead hydrangea blossoms are blue in high aluminum soil, while pink flowers are produced by low aluminum soil (pH about 6). (pH below 6). On a single shrub, soil with a pH of 6-7 yields flowers that are often purple or a combination of blue and pink.
Sprinkle sulpher (often approximately 1/2 cup) over the garden soil at the base of the hydrangea to increase the acidity of the soil for blue hydrangeas and then water it in. Sprinkle around 1/2 of lime on the soil at the base of the hydrangeas and water it in for more basic soil that produces pink hydrangeas. Patience is essential because the procedure would need to be done several times over the course of several months to produce the desired effects.
Note that companion plants may be impacted by shifting soil pH; therefore, check with your local nursery or gardener to confirm whether anything close by may be impacted.
When to Cut Flowers
These lovely blossoms are grown in part to show them off in vases, but they frequently don’t endure for very long after being cut. Try these two preservation techniques to stop rapid wilting.
- A major grocery store’s spice aisle is where you may purchase alum. On a cool morning, trim the hydrangeas, and plunge the stems right into water. Dip the freshly cut stem in the alum powder as you trim the stems to the appropriate height. Place the stems in a water-filled vase. People claim that this works even when the alum washes off for whatever reason.
- Alternately, use the technique described above to immediately position the stems of hydrangeas after cutting them. Boiling water should be poured into a secure container once it has cooled for a short while. The hydrangea stems should be cut to the required length, and the ends should be submerged for about 30 seconds in boiling water. Next, put the flowers in a vase with room temperature water and arrange them wherever you like (immediately).
Other Hydrangea Tips
It is better to purchase hydrangeas when they are in bloom because sellers frequently label them incorrectly by accident. Additionally, because the color is so reliant on the pH of the soil, as was discussed before, the bloom you start with may not be the bloom you end up with.
It’s crucial to ask your neighborhood nursery which species of hydrangea will thrive in your yard. They can potentially grow to be up to 12 feet tall and wide!
When is the best time to plant hydrangeas?
Learning the fundamentals of how to plant hydrangeas can help you save time and money, just like with most other items in your garden. You’ll improve your chances of enjoying big, vibrant hydrangea flowers for years to come by picking the appropriate site, getting the soil just right, and planting correctly.
When should I plant hydrangeas?
The best time to grow hydrangeas is in the fall, followed by early spring. The goal is to provide the shrub lots of time to develop a strong root system before it blooms. Early in the day or late in the day are the ideal times to plant. The day’s cooler hours provide relief from heat exhaustion. Water new plants frequently until they get established.
Locations to plant hydrangeas
The first step is knowing where to grow hydrangea plants. Hydrangeas are frequently grown in beds adjacent to houses or fences. This is so because hydrangeas prefer the mild early sun to the hot afternoon sun. A protected area with sunny mornings and shaded afternoons is the ideal spot to plant hydrangeas. This is frequently found on the north or south side of a house. Avoid planting underneath trees since it could cause competition for nutrients and water. Flowers and leaves can both be destroyed by strong winds.
hydrangea-friendly soil
The soil needs to be rich in organic matter for hydrangeas to thrive. Drainage is important. Although hydrangeas prefer damp soil, they cannot stand standing water. Root rot can be brought on by wet, poorly draining soils. Your hydrangeas could pass away in a matter of weeks. Consider adding a lot of compost to your heavy soil before planting to increase the soil’s quality.
Methods for planting hydrangeas
Simply dig planting holes that are 2 feet wider than the root ball for planting hydrangeas. So that your plant lies level with or just higher than the surrounding soil, match the depth of the hole to the size of the root ball. You can improve water drainage away from the plant’s base by making a small mound.
The best way to grow hydrangeas
Simple propagation methods can multiply a single hydrangea into several more. The optimal time to layer bigleaf and panicle hydrangeas is in the early to mid-summer. You only need to:
- Close to your hydrangea plant, make a tiny trench.
- Bend a branch such that the middle of the branch meets the earth in the trench (six to 12 inches of branch should extend past the trench).
- Where the branch meets the trench soil, make scuff marks on the bark.
- After the trench is filled, cover it with a paver, brick, or stone.
- The branch can be transplanted to a different area once it has established its own root system over time.
Hydrangeas with smooth or oakleaf leaves produce new growth from underground stems. Simply separate the baby plant from the main plant by digging it up. After then, it can be moved to a new spot.
How late may hydrangeas be planted?
When may I put a hydrangea in a planter outside? Anytime of the year is suitable for planting a potted hydrangea in the ground. The ideal seasons are, however, spring or autumn. Plant either in early fall when the soil will still be warm and before the frosts or after the spring frosts have passed.
Does Southern California have hydrangea plants?
In Southern California, hydrangeas thrive in partial shade because it keeps the soil moist and reduces the amount of water needed by the plant. A position that faces east or north is ideal, with the exception of coastal areas where plants can tolerate full light. Additionally, deciduous trees’ filtered shade is good for hydrangeas.
Can I currently plant hydrangeas?
Hydrangeas can be planted at any time, but spring and fall are the ideal seasons. They will require a lot of care to survive if you plant in the middle of the summer. Put and Grow. Once you’ve selected the right location (preferably one with soil that drains well), dig a hole that is twice as wide as the hydrangea’s container.
When should hydrangeas be planted outside?
Choose a time in late spring or early fall when the nights are cooler and there is little risk of frost. If you garden in an area where the ground freezes, put seeds at least six weeks before the first deadly frost of the fall. This allows plants to establish roots before the ground becomes really cold. To improve root insulation, place a 2-inch mulch layer around plants after planting.
Where to plant hydrangeas:
- A location with morning sun and afternoon shade is ideal. They’ll take more sun if you reside further north (possibly full sun all day).
- Think about the mature size and give it lots of room to expand.
- Pick a location with great drainage. If necessary, add compost to the soil.
- Plants won’t thrive if they are planted too close to a tree because of root competition and a lack of sunshine.
- Planting should not be done in open locations where strong winds could snap stems.
How to plant hydrangeas:
- By amending your soil with up to 15% organic matter and an all-purpose slow-release fertilizer, you may give your plant a good start (use half of what is recommended).
- Plant a little higher than you did while you were in the nursery container.
- In order to give the roots plenty of freedom to expand, the planting hole should be two to three times broader than the root ball.
- Before planting, gently untie the roots from their pots.
- Add the modified dirt back in and thoroughly water it.
- Planting in groups requires a minimum distance of 3 feet (more, if planting larger varieties).
Planting hydrangeas in pots:
- Put potting soil in a bag rather than garden dirt.
- Slow-release fertilizer should be added.
- For watering, leave 1 to 2 inches between the soil’s top and the pot’s rim.
- Make sure the pot includes space for the plant to grow and drainage holes.
How long does a hydrangea take to reach its maximum size?
I’ll address some of the most typical queries about hydrangea plant care in this section. If you can’t find your response here, post it in the comments section and I’ll respond as soon as possible.
Are hydrangeas easy to care for?
Hydrangeas are indeed quite simple to maintain when given the proper growing conditions. They are resilient plants that require little maintenance and will flourish for many years.
How big do hydrangeas grow?
According to the variety. Dwarf species can grow to only a few feet tall, while larger ones can grow up to 15 feet tall. Always look at the plant tag to see the precise size that your chosen hydrangea will reach.
Can hydrangeas tolerate full sun?
In colder climes, certain hydrangeas may be able to endure a placement in full sun. To achieve the greatest results, it’s better to put them where they will receive some partial shade.
How long does it take for a hydrangea to grow to full size?
Hydrangeas take between two and four years to attain their maximum size, despite the fact that they are fast-growing shrubs. Some people mature more quickly than others.
Hydrangeas are easy to grow and are tolerant of almost any climate. The nicest aspect is that you can have a wide variety of those big, beautiful blooms all summer long because there are so many different species. Your hydrangeas will flourish for many years to come with the right care.
Can hydrangeas survive in complete shade?
It’s no surprise that hydrangeas have grown to be so well-liked among gardeners given their profusion of blossoms and remarkable adaptability. There is a hydrangea for almost every garden because there are so many different types. They are certain to provide you happiness year after year if you give them a sunny place with well-draining soil. Will hydrangeas flourish in the shadow, though?
Full sun (more than 6 hours of direct sunlight) to part sun is ideal for hydrangea growth (4-6 hours sun). All hydrangeas can tolerate some shade, but the timing and nature of the shade should be taken into account. As long as they receive some early sun, they can spend the warmest part of the day in complete shade. In sweltering conditions, this is especially true. They don’t flower as frequently, though, and their stems tend to be weaker and floppier if they don’t get enough sun.
Don’t let a little shadow ruin your plans for a hydrangea garden. A list of hydrangeas that can tolerate shadow better than others has been assembled.
Do hydrangeas like shade or the sun?
With the ideal balance of morning sun and afternoon shade, hydrangeas flourish. Even the sun-loving Hydrangea paniculata will thrive in some shade. Some hydrangea cultivars may survive complete shadow, though.
The oakleaf hydrangea, also known as hydrangea quercifolia, is a substantial species of hydrangea that may reach heights of up to eight feet. In a shade garden, this big bush makes a beautiful backdrop. The height will provide excellent midsummer seclusion. Oakleaf hydrangeas are summer bloomers with mostly white blooms, elegant oakleaf-shaped leaves, and lovely peeling bark.
Hydrangea anomala ssp. petiolaris is another choice for full shade. This climbing species, which has lacy, white blossoms in the summer, can reach a height of 50 feet if it is given adequate support. The foliage is a rich shade of green and would look wonderful growing up a tree trunk or covering the face of a building. It would also look lovely covering the roof of a garden shed.
Full shade cultivars require the same upkeep as partial shade. In the deeper shade, it will be especially crucial to keep the plants free of leaf litter and with excellent airflow. Water your plant once a week after it has become established. Keep a watch on the leaves, and if you notice any drooping, especially during the hot summer months, water them right away. The importance of this increases in hotter regions.
These leaves’ unique shape would be a lovely complement to Hosta leaves. The white blossoms would contrast nicely with the lighter hues of your shady blooms and provide some brilliant brightness to your shaded locations.
Shade Varieties
There are a few different hydrangea cultivars that thrive in the shade. Some types can even thrive in zones 3 (which doesn’t warm up until later in the spring), which is one of the coldest growing regions. Let’s examine some of the best shade selections!
Hydrangea quercifolia ‘Snow queen’
The movie “Snow queen” is stunning. The flowers are stunning, as they are with all hydrangeas. These rose blush-colored blossoms appear in the middle of summer. The foliage of this plant is my favorite component. The leaves begin the season in a very deep green, gradually changing to a deep reddish bronze color, and finally finishing in that shade, offering a stunning splash of color to your fall landscape.
Hydrangea quercifolia ‘Alice’
With a height ranging between 12 and 15 feet, this Oakleaf Hydrangea is one among the biggest. In the summer, this plant blooms with incredibly deep cream-colored flowers. A woodland garden would be a truly lovely place for “Alice.” This cultivar would look especially beautiful if it were grown as a bordering hedge.
Hydrangea arborescens ‘Annabelle’
‘Annabelle’ enjoys partial shade and has some of the largest flowers in the hydrangea family (12 inches wide!). These enormous blossoms can be supported all season long by the sturdy stalks. This shrub can grow up to five feet tall and five feet broad, so give it plenty of area to expand. These enormous, all-white blossoms bloom for a long time.
In a mass planting, as a specimen shrub, or as a foundation planting, “Annabelle” would look lovely. These bushes should still be included in your cutting garden. Imagine a bunch of flowers that large! Wow!
