I recently got the chance to assess a university campus for bee-friendly landscape plants. Large trees and sprawling lawns made up the majority of the campus, creating a plush and welcoming blanket of greenery that encircled tall buildings and trees like draped velvet. I’m delighted to report that it provided a quiet retreat for students and many families using or passing through the campus with young children.
The campus had so many trees that they formed an almost closed canopy, giving the impression that the trees had given permission for structures to be placed amid them for our benefit.
On the university grounds, a variety of trees including oaks, American elms, ash, mimosas, catalpas, mulberries, willows, golden chain trees, lindens, flowering crab apples, hawthorns, cedar, fir, pine, horse chestnuts, honey locusts, and eastern redbuds flourished in harmony and profusion. Many of the huge shrubs and trees were pollinator-friendly.
Willows were the first bee-friendly trees to blossom in the spring, and they were soon followed by hawthorn, horse chestnut, red buds (both eastern and western), and flowering crab apples.
Up to the end of July, golden chain tree, honey locust, linden, catalpa, mimosa, and linden all produced continuous tree bloom.
As long as there are other pollinator-friendly plants blooming before and after them, each tree holds a significant amount of floral resources during bloom time and is beneficial to pollinators; bees require sustained floral resources during the growing season.
Conifers, ash, elm, and other wind-pollinated trees are generally unwelcoming to bees.
On campus, hydrangeas were widely planted, so it was fascinating to see which ones were good for pollinators and which weren’t. Although we don’t typically think of plants as being friendly to bees, some are actually quite alluring to bees while others are not.
There was a fairly lengthy planting of lacecap hydrangeas on the east side of a sizable structure. The more popular mop-head hydrangea macrophylla hortensis is unsuitable for bees since its flowers are all sterile and, while attractive to humans, provide neither pollen nor nectar for bees.
Although hydrangeas’ fruitful blossoms are little, unimportant, and not particularly eye-catching, bees are very drawn to them. A large core cluster of fertile flowers is surrounded by stunning sterile flowers on lacecap hydrangeas.
They combine grace and delicacy with flowers that are friendly to pollinators, giving you the best of both worlds. These beautiful flowers are available in a variety of hues, including white, blue, and purple.
Hydrangea aspera, sometimes known as rough-leaf hydrangea, is a too rarely planted lacecap variety. Zone 9 locations with maritime influences, enough water, and annual composting are best suited for its use. This lovely big shrub, which grows to a height of 8 feet and flowers in the late summer, needs filtered shade.
A ring of light purple sterile blooms surrounds the bright purple, extremely fragrant fertile flowers. Both we and the bees adore its blossoms.
The appeal of the various hydrangea paniculata varieties to bees varies. The elongated, white flower heads typically contain a mixture of viable and sterile blooms.
Some varieties have non-scented, primarily sterile flowers whereas others have highly fragrant, bee-friendly blossoms. All are garish.
It is better to visit a nursery and distinguish between plants with a lot of bees visiting them and others that are not aromatic. The plants can range in size from three feet to roughly six or eight feet. Numerous cultivars exist.
Native to the eastern United States, hydrangea arborescens is frequently planted along the coast or in regions that receive a lot of coastal impact. ‘Annabelle’ is a popular cultivar.
It features very enormous umbels of white flowers that resemble mopheads, but each blossom is somewhat smaller than the mophead varieties, giving the flowering plant a softer and more elegant appearance.
The leaves are a brighter shade of green, much smaller, and less waxy. Large flower heads and weak stems can cause flowers to occasionally topple down.
While cultivars like “Haas Halo” have lacecap blooms made up of both fertile and sterile flowers and are exceedingly spectacular and bee-friendly, this cultivar only has sterile flowers. H. arborescens has exclusively viable blooms in its wild form. The scent of hydrangeas can help determine whether they are bee-friendly.
Which hydrangea varieties don’t draw bees?
You might think that hydrangeas are a bee attraction given their huge blossoms, but that isn’t necessarily the case. While certain varieties of hydrangeas draw bees, others do not. Flowers on mophead hydrangeas are sterile and lack nectar that would draw pollinators. Lacecap hydrangeas do, however, produce fruitful blossoms that draw bees. Pollinators like bees are also drawn to Climbing Hydrangeas, Oakleaf Hydrangeas, and Smooth Hydrangeas.
Mophead hydrangeas are the best choice if you want to keep bees away. On the other hand, if you want to make a space that attracts pollinators, consider growing Lacecap, Climbing, Oakleaf, or Smooth hydrangeas. The Lacecap and Oakleaf Hydrangeas appear to draw the greatest number of bees and other pollinators among these types.
You might ask why hydrangeas don’t draw in more pollinators given their opulent blossoms. Don’t pollinators want big, vibrant flowers, like bees do? It turns out that the nectar and pollen that the pollinators are truly pursuing are not present in every Hydrangea bloom. Most of the spectacular flower clusters that Hydrangeas are valued for are sterile. The cluster’s only viable flowers, which have nectar and pollen, are located inside.
The “petals on Hydrangeas are technically sepals, not blooms,” as the saying goes. Normally, these sepals would be green in plants. However, the outer part of hydrangeas mimics the shape that we usually refer to as a flower.
In the natural, hydrangeas produce more little, fruitful blossoms rather than large, spectacular flowers. The proportion of fertile to sterile flowers has changed as Hydrangeas have been bred by growers to produce larger blooms.
Because they don’t create a lot of pollen, hydrangeas are a suitable choice for allergy sufferers. Since there is no need to worry about pollen allergies, Hydrangeas are excellent for cutting and bringing indoors.
Do hydrangeas entice wasps or bees?
The nectar and pollen-rich flowers of hydrangeas draw a variety of bee, fly, and wasp species as well as other flying pollinators. They don’t draw houseflies, hornets, yellowjackets, or the majority of predatory wasps because these insects are generally carnivores that eat carrion or trash and rarely consume nectar or pollen.
One of the main reasons that flowering plants exist and why most flowers are as beautiful as they are is because they attract pollinators. The color, form, and shape of a flower are created by nature to draw the type of animal she wants to help with fertilization. If you don’t want the pollinators, you must get rid of the plants, or at the very least, the flowers, or move them to an area where they won’t bother you.
Do hydrangeas entice bees and butterflies?
When it comes to pollinator plants, hydrangeas are not often the first thing that come to mind. However, lacecap types like Little Quick Fire, which conspicuously exhibit their fertile florets that are rich in nectar and pollen, do a great job of generating buzz. Little Quick Fire is also a panicle hydrangea, which requires little maintenance and thrives in both hot and cold areas. Even though mophead kinds—those that produce the large, full, fluffy flower heads—are typically regarded as more showy, choosing lacecap variants guarantees that you’re also improving the aesthetics of your landscape.
How can hydrangeas be protected from bees?
May is here! Sunlight is present! Bees are humming loudly. However, might you not perhaps prefer the bees to buzz a little farther away from you? Here are some all-natural strategies for repelling bees.
We are spending more and more time outside as the weather warms up. We might be organizing a fun outdoor dinner party or spending time in our garden once more. Bees buzzing all around you, though, can completely destroy the pleasant air. This means it’s time to make plans for how to avoid harming the environment while enjoying time in the sun and keeping bees and other insects at bay.
Insecticides are often used by many individuals to get rid of bees, but it has been shown that this is not the greatest solution. Insecticides play a significant role in the fall of the bee population that has been occurring since 2006. It’s important to steer clear of measures that will eliminate bees because they are useful to humans for a variety of reasons. Fortunately, there are simple, natural ways to deter bees from your outdoor activities without harming the bees or the ecosystem in the long run.
Cucumber skin
Bees can be effectively kept out of certain, constrained regions by using cucumber peel. For instance, you might start opening your windows and doors to let the warm air inside. But if bees also decide to enter, you might want to think about placing pieces of cucumber peel on or near your window frames. This is effective in some garden areas as well.
Peppermint
Bees like to stay away from peppermint-scented regions and plants where they congregate. They will avoid the plants, and therefore your house, if you have peppermint plants outdoors or nearby. It is a win-win circumstance. When the plants are finished growing, you won’t have to deal with the buzzing in your brain and you’ll enjoy delicious peppermint for yourself!
Cinnamon
A fantastic approach to scare away bees from a location is to spread cinnamon there. It will have a long-lasting effect, but you must be sure you do it every day for at least a week.
pulverized garlic
You can create a fantastic bee repellent by chopping up garlic and soaking it in water for a few days. Place it around your plants or in areas where people congregate outside.
Vanilla concoction
Perhaps your skin is more attractive to bees than your house or yard. Bees love vanilla extract, so use it to keep them off your skin. Even in a region where bees are common, a tablespoon of vanilla extract diluted in water will keep them away from you (baby oil will also work if you don’t like vanilla).
infant powder
Finally, while organic baby powder is a helpful deterrent for bees, not all varieties of baby powder are really natural. Then just sprinkle it in any locations you think are essential. Bees must be eliminated!
Are hydrangeas a mosquito magnet?
The magnificent blossoms of hydrangeas make them a popular choice for lawns and gardens. However, some gardeners worry that their sizable hydrangea shrubs might be attracting mosquitoes to the yard.
No proof exists that hydrangeas draw mosquitoes. However, mosquitoes are drawn to areas with lots of vegetation and standing water. Although hydrangeas themselves are not an attractant, the high moisture requirements of hydrangeas allow for the creation of mosquito-friendly environments.
Let’s examine what attracts mosquitoes in more detail, which insects hydrangeas attract, and how to reduce the amount of mosquitoes in your yard.
Check out the DynaTrap Mosquito & Flying Insect Trap, which protects up to half an acre and kills mosquitoes, flies, wasps, gnats, and other flying insects (link to Amazon).
What is the ideal location 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. Many people plant hydrangeas in beds next to their homes 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.
Do hydrangeas draw in animals?
Its leaves don’t seem pleasant to insects, so there isn’t much value there, and most importantly, the blooms seem so ugly to insects. It isn’t dense enough or prickly to provide birds with a place to shelter. It’s really easy to understand why. The enormous flower globes that you notice on so many hydrangeas are completely sterile.
What flowers are undesirable to bees?
Although pollination by bees is necessary for flowers, as we all taught in school, it doesn’t imply we want them swarming around in our backyards. Bees and wasps can quickly ruin time spent outside, whether you are allergic to them or not. Don’t let your fear of being stung prevent you from having fun this summer. When it comes to fending off bees and wasps, a few simple changes to your landscape can have a significant impact. A list of 10 plants that deter bees and wasps is provided below. Resuming your season-long enjoyment after adding some to your backyard landscaping.
Of course, if you notice any bees or wasps on your property, call your neighborhood Ehrlich Pest Control office to find out what you can do to get rid of them and stop them from coming back.
Cucumber
This well-liked vegetable not only enhances summer salads but also deters wasps and bees. The acidic cucumber peels’ harsh flavor turns off bees and wasps.
There are several ways you may make use of cucumbers in your yard. You may either scatter cucumber peels across the garden or grow cucumber plants that will produce fresh fruit for snacks and drinks. Cucumbers are tropical vegetables, so if you decide to grow them, you’ll need warm weather and lots of moisture.
Basil
Another wonderful plant for your garden that serves as both a culinary ingredient and a pest deterrent is basil. While bees and wasps may not mind the scent of basil in a hearty tomato sauce, we humans do not. Basil enjoys a place that receives 6 to 8 hours each day of direct sunlight since it needs heat to thrive efficiently. To prevent drowning the basil plants and/or inducing root rot, the soil must be well-drained even if it should be kept moist.
Geraniums
Because bees cannot perceive the color red, geraniums, especially red geraniums, can be useful in deterring bees. Although it may seem odd that a flower would deter bees, these blooms have a fragrance that the stinging insect does not particularly enjoy and contain little to no pollen. Geraniums can be brought indoors to overwinter during the colder months and prefer to receive 4-6 hours of direct sunlight each day.
Wormwood
Absinthe, a component in wormwood that is poisonous to insects, is present. Bees and wasps typically avoid it because of its strong aroma, which warns them of any potential threats. Direct sunlight and well-drained soil are required for wormwood. Wormwood should be planted with caution because it can obliterate nearby plants.
Mint
Although mint has a pleasant aroma in the human world, stinging insects do not appreciate it. Although they may withstand some shade, mint plants need to be carefully monitored. They may easily take over a garden due to their speedy growth.
Eucalyptus
This fragrant shrub is a favorite of koala bears, but not of bees and wasps. You can grow eucalyptus in a garden or in containers. It requires a huge bit of light in any case. The eucalyptus plant can withstand drought, so give it a little time to dry out in between waterings.
Marigolds
Like most of the other plants on our list, the vibrant marigold adds beauty to gardens and deters insects with its pungent scent. It does not necessarily deter honeybees that are looking for nectar, but it does not appeal to wasps. Particularly when planted in the ground, marigolds are incredibly hardy and require little maintenance. Try using red types of plants to deter bees, like you would with geraniums.
Citronella
Citronella is primarily recognized for its ability to repel mosquitoes, but wasps and bees can also find it repulsive due to its overpowering odor. Although it may be grown indoors or outdoors, it prefers at least six hours of direct sunlight daily, whether it’s by a window or in the sun. The soil around the citronella plant should continue to drain well.
Pennyroyal
Bees and wasps absolutely detest pennyroyal because of its mint-like fragrance. Pennyroyal is a fantastic option for pots because it is a very modest plant with a height of 6 to 12 inches. Although this plant is quite simple to manage, it needs to be watered frequently to prevent drying out.
Pitcher Plants
Compared to the other plants on this list, these ones function rather differently. Pitcher plants aid in the control of bees and wasps rather than putting them off. Pitcher plants are predators that capture and consume insects for their own food. Insects are drawn into the flower, where a slick surface leads them to slip and perish in a watery pool.
Because it cannot take tap, bottled, or filtered water, this sort of flower can be challenging to care for because it only tolerates rainwater or distilled water. Because pitcher plants have evolved to get their minerals from the insects they catch rather than from the accumulation of minerals in that type of water, this can be harmful to them. Pitcher plants need full, direct sunlight as well.
When choosing flowers for your yard, try to stay away from blue, violet, and yellow-hued plants as much as you can because these are bees’ favorite colors. These colors will draw bees to flowers in particular. Additionally, trumpet-shaped flowers are a barrier since they naturally make it more challenging for bees to get the nectar.
