When To Prune Hydrangeas In Florida

Depending on which group the plant belongs to, the timing and extent of pruning are determined:

Advice on Pruning for Group 1:

  • As the days get shorter and the weather gets colder in the late summer and fall, buds for the following year’s blooms start to form.
  • Typically, removing dead, diseased, or damaged branches is all that is required to preserve shape, size, and a healthy plant. Otherwise, gentle pruning ought to be practiced.
  • In the summer, trimming should begin as soon as flowering ends, but no later than August 1. Pruning should not be done in the fall, winter, or spring because you risk removing fresh buds.
  • Tip-pruning the branches in the spring as the leaves begin to appear can promote more numerous, smaller flower heads as opposed to fewer, larger flower heads.

Advice on Pruning for Group 2:

  • On the growth of the current year, flower buds form.
  • Early in the spring, as the leaves are starting to emerge, prune.
  • Just above a node, prune branches back by half to a third.
  • After that, prune any fragile or spindly branches.
  • Minimal trimming encourages huge, strong bushes with many of tiny flower heads in H. arborescens. Hard pruning between 12 and 18 inches from the ground, or even all the way down, will result in fewer but larger flower heads that may flop if unsupported.
  • For H. paniculata, remove the surrounding smaller wood while leaving the larger stems in order to establish a sturdy foundation.

Pruning may be connected to flower head size. Shoots will grow more vigorously and flower heads will be bigger and fewer with more rigorous trimming. Smaller but more numerous flower heads may result from less aggressive or tip pruning.

Consideration of hydrangeas’ mature size is the best piece of advise. Place them in a location where they won’t outgrow and won’t need a lot of pruning to keep them in check. Hydrangeas don’t need to be pruned precisely or often; as long as dead wood is removed, they will remain healthy and continue to develop and bloom.

In Florida, how should I take care of hydrangeas?

For Easter, we bought a bunch of hydrangeas. What should I do when I plant something in my landscape?

The best place for hydrangeas in the landscaping can help reduce the amount of maintenance required. The optimal site is one with morning sun and afternoon shade, or all-day filtered sun. Find an area that is naturally moist as well, if at all possible.

Increase the amount of organic matter in sandy soils to keep them moist. Hydrangeas prefer a steady damp but not wet environment. Water as soon as the soil’s surface seems dry to the touch, which may be every day as the plants get established. Keep a 2- to 3-inch mulch layer in place beginning a short distance from the stems. During the warmer months, feed your landscape according to the label’s instructions. Keep a fungicide on hand as well to use as necessary. Leaf spotting and powdery mildew are common problems for hydrangeas.

My okra plants are growing well, however the new leaves have some black spots that are moving slowly. Are those insects?

Aphids, which have a pear-like appearance and are about the size of a pinhead, are fond of eating okra. They are misbehaving by sucking the fluids from the fresh stems and leaves. Others use insecticidal soap, while some gardeners choose to wash them off. To be effective, soap sprays must hit the insects. It is recommended to use soap sprays available at garden centers as homemade remedies might occasionally harm plants. Traditional insecticides with labels for okra aphid control can also be found at your local garden center.

Q: I see that each month has the moon sign planting dates specified. Do they actually aid in crop growth?

A lot of traditional farmers and gardeners rely on planting dates based on the moon’s transit through each astrological sign. These days, it is advised for the best plantings to use some indications since they are more productive than others. It might be more accurate to state that many people believe using moon sign planting dates promotes healthy plant growth. Try these dates out on your upcoming garden or landscaping job to see if anything changes.

My plants need fertilizing, but there are so many options available. Is one type of fertilizer superior to another?

A: Fertilizers for use in residential landscaping can be found on the shelves of garden centers. You can pick from items that work quickly in the water to granules that release food gradually over months, feeding the plants. Your decision may be influenced by how frequently you want to fertilize your plants.

The quick-acting products might be acceptable if you prefer to be in charge and fertilize frequently. However, a steady release that offers two or more months of feeding could be appropriate given that many gardeners also have other jobs to complete. The slower-releasing products are more economical and cost-effective for the environment. Only if you have plants with particular requirements, like azaleas, blueberries, or certain fruit trees, would you choose something other than a general landscape fertilizer.

We have a trash can full of ashes from the fireplace. Can we use them as fertilizer in our gardens?

A: Use caution when sprinkling wood ashes across the garden and landscape. Wood ashes can be useful since they have a lot of phosphorus, potassium, and a few trace elements but nearly no nitrogen. One issue is that wood ashes react quickly to become alkaline.

Wood ashes could change the soil’s pH, making their use harmful for plants that like acidic environments, such as azaleas and blueberries. If you want to keep the flowers on hydrangeas blue, you wouldn’t use them surrounding them. They should only be utilized if your soil is acidic, and even then, a half-inch dispersion over mulch and soil is sufficient. If necessary, add a few cups to each compost pile to balance pH and add nutrients.

A: The mulch that was just applied to our landscape was placed around the citrus trees. These, it seems to me, dislike mulch. Is this a fact?

A: You can put mulch up to about a foot or two away from citrus tree trunks, but not much closer. Actually, all tree, shrub, and perennial stems and trunks should be kept several inches away from mulch. Keeping these areas damp could result in rot or other pest issues. Keep mulch layers between two and three inches thick as well. Overmulching can hinder root growth by reducing water and air penetration into the soil. It’s ideal to keep vegetable gardens’ mulch layers to two inches and flower beds’ layers to one inch. Only a light topping may be required if the soil surface is covered by a thick layer of mulch.

When is the best time of year to prune my hydrangeas?

The type of hydrangea you have will determine when to prune it. It is necessary to prune hydrangeas that bloom on new growth in late winter or early spring. Hydrangeas that flower on old, woody growth must be clipped after flowering in the summer.

The specialists at the seed and plant firm Thompson & Morgan state that most hydrangeas are clipped in early spring, ideally in February or March, with the exception of climbing hydrangeas, which are pruned in summer (opens in new tab).

The clearest indicator that your hydrangea is ready for trimming is when all of the seed heads have dried up and new, vibrant green buds have begun to emerge. When you notice those, you’ll know it’s time to prune, according to Lee Burkhill of Garden Ninja (opens in new tab).

Although many hydrangea varieties are pruned at the same time of year—late winter or early spring—the methods for each variety vary.

Should hydrangeas be pruned annually?

Remove crossed and dead stems, then prune the plant into shape. Pruning does not have to be done annually. These varieties can be encouraged to grow into trees. The trunk and primary branches must be developed carefully by pruning.

What occurs if hydrangeas are not pruned?

If and when you prune is the key to happy, healthy hydrangea flowers. Of course, fertilizing and offering the ideal environment have a lot to recommend them. However, if you don’t prune properly, your efforts will be in vain. Deadheading is not the same as trimming. Pruning refers to more drastic cutting to preserve shape or remove dead growth. However, feel free to discard spent blossoms or cut fresh ones to use in arrangements.

Hydrangeas can bloom on either fresh wood or old wood, depending on the species. The wood from which they blossom determines whether and when to prune.

Old wood-blooming hydrangeas do not require pruning and benefit from it. They’ll blossom more abundantly the next season if you leave them alone. But feel free to deadhead or gently thin. Just keep in mind that while new growth may appear, it won’t bloom until the following season. In our region, four different species blossom on aged wood. Additionally, they are not limited to the hues displayed here.

Climb using suckers. On your wall or trellis, resist the desire to remove the dormant growth.

The flower heads are more conical in appearance, and the leaves are large and resemble oak leaves. It’s a pleasant surprise for a hydrangea when its leaves turn reddish-orange in the fall.

They are very comparable to lacecap types, but smaller and with more compact leaves.

Pruning should be done in late winter or early spring on hydrangeas that bloom on new wood. Trim back to two feet to prune to shape. The next season’s blossoms are produced by strong, fresh growth that is encouraged by trimming. In our region, there are two types that bloom on fresh wood. They are also not restricted to the colors displayed.

Oakleaf variants are not included in cone-shaped blooms. Keep the blooms on throughout the winter to provide interest; even dried out, they are quite lovely.

regarded as a wild kind. They often have smaller blooms and leaves than Bigleaf variants and are completely white. They enjoy full sun and can grow very tall.

Knowing whether or when to prune now will help you avoid the disappointment of a hydrangea that doesn’t blossom. Don’t forget that a robust shrub will produce more gorgeous blossoms if it has well-draining soil and good organic fertilizer. Come on in, and we’ll show you where to go to develop your green thumb.

In Florida, do hydrangeas bloom all year long?

The hydrangea is a perennial blooming shrub that is cultivated for its enormous, pastel-colored blossoms. The sandy soil in Orlando provides a difficulty for hydrangea gardeners. The University of Florida’s agronomists advise Orlando gardeners to grow Hydrangea macrophylla, also known as Bigleaf, French, or Florist’s hydrangea. One of the options is the Endless Summer variety. Hydrangeas bloom in Orlando in the late spring and early summer.

Give your hydrangea the right quantity of sunshine. Plant the hydrangea where it will receive afternoon shade because morning sun is OK but it will need protection from the intense heat of the sun.

  • The hydrangea is a perennial blooming shrub that is cultivated for its enormous, pastel-colored blossoms.
  • Plant the hydrangea where it will receive afternoon shade because morning sun is OK but it will need protection from the intense heat of the sun.

Make certain the hydrangea is planted in well-drained soil. Hydrangea thrives in water, but if the roots are always wet, they will suffer.

During the hottest portion of the summer, keep the soil moist but not waterlogged. At other times, let the soil dry to within 1 inch of the surface. Due to the sandy soil in the area, gardeners in Orlando will need to water their plants significantly more regularly.

At the hydrangea’s base, spread a 3-inch layer of mulch, being careful not to let it touch the bark. Spread it out as wide as the plant and keep it at least 2 inches away from the trunk. As a result, weeds will have a harder time growing and the soil will stay cooler in the summer.

  • Make certain the hydrangea is planted in well-drained soil.
  • At the hydrangea’s base, spread a 3-inch layer of mulch, being careful not to let it touch the bark.

During the summer, treat your hydrangea twice with a balanced fertilizer like 10-10-10. Apply the product at the rate recommended on the package. After August, avoid fertilizing your hydrangea. Feed your hydrangea every two weeks from March to November if you are growing it in a container. From December to February, reduce feedings to once a month.

If you desire larger blossoms, prune your Hydrangea arborescens (like Annabelle) back to 1 foot tall in late winter. Prune it to 2 feet or more if you don’t care about size and want additional blossoms. Early June is the best time to prune oakleaf hydrangeas. Nikko Blue and other Hydrangea macrophylla need to be clipped when plants start to sprout leaves in the spring. Just above the blossom, trim the stems. Anytime is a good moment to prune Endless Summer.

  • During the summer, treat your hydrangea twice with a balanced fertilizer like 10-10-10.
  • If you desire larger blossoms, prune your Hydrangea arborescens (like Annabelle) back to 1 foot tall in late winter.

When the first frost hits new hydrangea plants, cover them. Plants that are more established are better equipped to withstand cold temperatures. Cover even the mature hydrangea bush if the weather should suddenly turn cold or hot.

In Florida, do hydrangeas enjoy direct sunlight?

What is your favorite plant? is usually one of the first inquiries after people learn what I do for a livelihood. That question can be challenging to answer because I’m a bit of a plant nerd! But I always come back to the same response: “Hydrangea. My fellow gardeners and I appreciate hydrangeas for a variety of factors. A hydrangea in full, billowy bloom is without a doubt one of the few plants that inspire more happy memories of summers past or lead to more impulsive purchases at nurseries. Few specimen bushes offer more floral punch while necessitating less maintenance from the grower. My own passion for hydrangeas began with my first attempt at propagation, when a softwood cutting of Hydrangea macrophylla ‘Nikko Blue’—taken with the assistance of someone much more experienced than I—seemed to magically sprout roots in a makeshift greenhouse made of a cypress box with a rusty, crusty sliding glass door. The hydrangeas got me. Despite having all of these positive qualities to its name, the genus Hydrangea is nevertheless neglected and underestimated in contemporary settings. Let’s discuss some of the best Hydrangea species and cultivars to search for at the nursery as well as the two main reasons why gardeners struggle and become frustrated with hydrangeas in the landscape.

First off, hydrangeas are known for using a lot of water. Hydrangeas are sensitive to water, as their name might imply (the Greek word for water is “hydor”). They merely show signs of drought more quickly than most other plants, which does not necessarily suggest that they need more or less water than other plants. This characteristic makes hydrangea an especially valuable indicator plant in the landscape. In general, hydrangeas wilt in the afternoon heat; this is completely normal. This is especially true for those that were planted in too much sun. However, the gardener will know that irrigation is necessary if the plants are still wilting the next morning. The plants could start to deteriorate if you don’t provide watering quickly after they inform you they need it. Consider this feature as an early warning system rather than a downside. What other plant shows such concern for us gardeners?

The second most common cause of hydrandea failure is poor site selection. In Florida, growing hydrangeas in full sun produces less than stellar results. All hydrangea species thrive best when planted in areas that receive at least some afternoon shade, if not filtered shade all day long. The negative effects of afternoon sun exposure include increased wilting due to heat stress, higher irrigation needs, and “bleached flower colour.” Never forget that growing the proper plant in the incorrect location is less frustrating than other situations!

Now that you’ve learned how to grow hydrangeas successfully, it’s time to choose the right plant for your yard! For the gardener’s consideration in Northwest Florida, three main species—H. macrophylla (Bigleaf Hydrangea), H. quercifolia (Oakleaf Hydrangea), and H. paniculata—perform notably better here than the rest of their relatives (Panicle Hydrangea).

When in bloom, H. macrophylla, the traditional hydrangea that everyone’s grandmother cultivated, stands out as one of the most distinctive plants in the shaded Southern landscape. H. macrophylla is an incredibly low maintenance plant, requiring only occasional irrigation and seldom fertilizer; H. macrophylla even tolerates salt spray and may be grown on the Gulf Coast! It has enormous “mopheads of inflorescences in stunning colours of blue (or pink, depending on soil pH). The majority of inquiries I get about H. macrophylla concern plants that aren’t flowering because they were pruned at the wrong time of year. Pruning once-blooming traditional cultivars like “Nikko Blue” as soon as flowering is ended in the late summer will produce the finest flowering returns. The wood from the previous season is where these plants establish their flower buds; pruning older varieties in the fall or winter may invigorate the plant, but it will stop it from blooming the next year. Fortunately, improvements in hydrangea breeding over the past 20 years have offered gardeners the option of planting remontant cultivars that bloom on wood from the current season. Remontant cultivars like “Endless Summer,” “Penny Mac,” “Bloomstruck,” and “All Season Beauty,” which are frequently sold, offer a similar early summer flower display to the traditional varieties but continue to bloom intermittently for the remainder of the summer. Even better, they can be cut back at any time without affecting the bloom display for the following season!

The natural Oakleaf Hydrangea is the next option for those seeking to diversify their hydrangea collection (H. quercifolia). Native to Florida, the oakleaf hydrangea grows untamed around the northern end of the Apalachicola River in steep, shaded ravines. The Oakleaf would be worthwhile to plant even if it never bloomed since it has enormous, oak-shaped leaves that may grow up to a foot long and give Floridians some of the best fall foliage color. The flowers, like with all hydrangea species, are the major attraction. This species has 8–10 white flowers in panicles that are carried gracefully above the rough-textured leaves. In addition to these qualities, Oakleaf Hydrangeas are quite simple to cultivate, reaching heights of up to 10′ and requiring only proper irrigation and some shade during the heat of the day from the gardener. Look for the cultivars “Alice,” “Semmes Beauty,” and “Snowflake,” which are the author’s favorites. These H. quercifolia cultivars and selections all do exceptionally well in Northwest Florida.

Last but not least, H. paniculata, the newest hydrangea species introduced to Florida gardens, has made tremendous strides in the landscape business during the past ten years. H. paniculata, which is primarily grown as the cultivar “Limelight,” solves some of the shortcomings of the two aforementioned species because it can withstand full sun and requires considerably less water, perhaps making it a more sustainable plant for many situations. Similar to the remontant H. macrophylla varieties, this plant blooms on new wood and even seems to relish a harsh pruning each winter; plants that have undergone this pruning appear to be more vigorous the following season and produce larger greenish-white flower panicles than those that have not. H. paniculata, in particular “Limelight,” is a valuable addition to any landscape, despite the fact that it is a relative newcomer.

You can see that there is a hydrangea for every yard, and no authentically Southern landscape is complete without a few of them. This summer, when browsing your neighborhood garden center, check for the options and species described above, plant them correctly, and then take pleasure in the succeeding yearly flower display for many years to come! Who knows, you might develop a love for hydrangeas as I did!
