How do you keep butterfly bushes blooming?
Deadheading Butterfly Bush
As soon as you notice flowers starting to fade, cut them back by deadheading. If you trim the spent flower spikes back to the next flower node on the branch, this will encourage your butterfly bush to bloom again.
Do butterfly bushes need to be cut back for winter?
Most butterfly bushes lose their leaves in late fall, and the roots remain viable underground while the plant winters over. That means in most growing zones, there is no need to prune your butterfly bush before winter. In fact, pruning too late in fall could leave it more susceptible to damage.
Why is butterfly bush bad?
If you're intent on attracting butterflies to your garden, you should think about succession planting — that is, make sure to have something blooming at all times. One of the reasons butterfly bush is so popular with gardeners is because its long season of bloom takes some of the guesswork out of succession planting.
The bush should bloom abundantly even in its first year. In warmer climates, the bushes will grow into trees and develop rugged trunks that peel; peeling is normal.
Prune in spring, after the new growth emerges.
But particularly in cold climates, this can leave your butterfly bush more susceptible to damage over winter. Do not prune until you see green buds on the stems.
Butterfly bushes, a double-edge sword
Its popularity has real reasons: the plant grows fast, flowers very early on in its life cycle, and produces flowers throughout its life span of up to 30 years. The flowers smell good, are very showy and pretty, with large clusters that bloom for several days.
The flowers from this bush is an attraction for hummingbirds because it has a high nectar count. Additionally, they are drawn to the long, brightly colored spikes resembling lilacs. As a result, it is possible to create a butterfly and hummingbird garden by including this gorgeous bloom.
“Butterfly bush just doesn't stay where we plant it,” He said. This detail can spell trouble for both your yard as well as that of your neighbors or any protected natural areas in your community. What's worse is that the invasive plant can also contribute to the collapse of food webs.
While pruning is not absolutely necessary, butterfly bushes tend to bloom better and keep a better shape if pruned hard each spring. They can also be pruned in summer to encourage new blooms, or just to tame untidy growth.
Butterfly bushes are perennial plants that die back to the ground every winter. They then send out new growth from the roots in the spring. You can prune them either in the late fall or in the early spring before the new growth starts.
Most people prefer to cut back the entire shrub to within a foot or two (31-61 cm.) from the ground, which actually allows it to become more manageable. Without pruning, the butterfly bush may become a bit unruly.
Butterfly bushes (Buddleja davidii) develop the most flowers when pruned in spring before the new wood begins to sprout, so you can prune as late as April if there is no new growth. Further pruning into summer can increase blooming.
Light: Butterfly bushes grow and flower best in full sun. They will grow fine in part shade, especially in warmer climates, but their flowering may be reduced. Soil: Butterfly bushes are not particular about the soil conditions, as long as it drains well. Poorly-drained soils can cause root rot.
Butterfly Bush is a deciduous shrub that can grow up to 15 feet high. The opposite-growing leaves, 5-10 inches long, have jagged edges. Butterfly Bush blooms from mid-summer to early fall. Flowers form drooping or upright spikes at the end of branches.
When Can You Transplant Butterfly Bushes? Butterfly bushes are quite hardy and can transplant easily. Transplanting a butterfly bush is usually accomplished in either spring or fall. Transplant prior to new growth in spring or once its foliage has died down in the fall.
Butterfly bush will grow wild if you let it, self-seeding and spreading into new areas of the garden, or growing vigorously in terms of height and spread. It flowers on new wood, so pruning aggressively in late winter or early spring will help to ensure more flowers in the summer.
Pair butterfly bushes with Verbena bonariensis, pineapple sage, purple salvia, lantana, swamp milkweed and asters. Some dwarf varieties of butterfly bush can be grown well in containers.
The fast-growing butterfly bush reaches a mature height of 6 to 10 feet tall in one or two growing seasons. The cone or wand-shaped flower heads grow 5 to 12 inches long and bloom from summer through fall.
Planting a butterfly bush in an optimum location minimizes the time you'll spend on maintenance. Choose a sunny or partly shaded area where the soil is well-drained. Soil that is constantly wet encourages rot. When planted in good quality garden soil, a butterfly bush rarely needs fertilizer.
Always prune just above some new leaf growth to encourage is a mass of new foliage. This pruning might seem a bit radical, but come spring, it'll be back looking fantastic." "So whatever the colour, size or form, these tough-as-boots bird and butterfly magnets could be a great addition to your garden!"
Although they are mostly known as blood-feeders, mosquitoes also drink nectar from flowers. The scientists chose the butterfly bush (Buddleja davidii) for their experiment because it's a very hardy plant that flowers throughout the year, and mosquitoes are attracted to it.
Butterfly bush is best planted in the spring or fall. If planting in fall, make sure to get them in the ground well before first frost in order to develop a good root system before colder temperatures set in.
This method of fertilization should only be done once a year, and is best done in late fall after leaf drop, or in early spring before bud break. Liquid fertilizers (such as Miracle Gro) are mixed with water and applied the same as you would water the plant (see product for specific details).
Pests that Attack Butterfly Bushes
Even though the butterfly bush has good resistance against pests and diseases, some predators such as wasps, spiders, birds, ants, aphids and flies can threaten it. Japanese beetles, spider mites and a species known as the checkerspot butterfly are also known to attack this plant.
Although butterfly bushes (Buddleja davidii) are not edible, they are no more toxic than any garden plant. They should be safe to plant where children, dogs, cats, and other animals live. In fact, butterfly bushes are deer resistant. They attract and feed nectar to hummingbirds and butterflies.
Bees are in love with butterfly bushes because they offer high amounts of nectar. There these butterfly bushes end up becoming highly attractive to pollinators like bees and butterflies. The butterfly bushes distract these pollinators from several other flowering species.
Buddleia Breeders to the Rescue
Buddleia breeders produced cultivars that are, in effect, sterile. These hybrids produce so little seed (less than 2% of traditional butterfly bushes), they are considered non-invasive varieties.
Butterfly Garden Flowers
Trimming should be done immediately after flowering stops in summer, but no later than August 1. Do not prune in fall, winter, or spring or you could be cutting off new buds. Tip-pruning the branches as leaves emerge in spring can encourage multiple, smaller flower heads rather than fewer larger flower heads.
If the wilting leaves are shriveled and brown, the butterfly bush is suffering from lack of water. The butterfly bush needs water during its growth season in early spring and during dry spells throughout the season. If the wilting leaves are shriveled and green, the shrub suffers from herbicide toxicity.
