How To Care

When planting your Butterfly Bush be sure you have the right location and conditions for your new shrub to thrive. Spring and Fall are ideal times to plant. However, if you avoid freezing and hot temperatures you can plant almost any time of the year.

Butterfly bushes tolerate full sun and part shade and are adaptable to a variety of soils as long as your soil is well drained. If your soil is nutrient rich your Butterfly bush will not require fertilizer. Fertilize in early spring and when planting if your soil is lacking. Choose a basic slow release fertilizer for flowering plants. When planting take care not to burn the roots by mixing the fertilizer into the soil before placing your bush in the hole. Water well when your plant is newly planted, but otherwise Butterfly bushes are drought tolerant and only require watering during dry, hot periods. Butterfly bushes don't require pruning, but if you would like to maintain size, these shrubs tolerate heavy pruning. In cooler climates where this shrub acts more like a perennial, trim within a couple inches of the ground in late winter or early spring. Mulching is a good choice especially in colder regions to protect the roots from freezing temperatures.

The best way to prevent disease and pests is by providing the appropriate care for your plants. Proper location choice, watering, and fertilization are the keys to your success. Butterfly bushes are quite resilient and only rarely have issues. The most common pests affecting this shrub are Japanese beetles and caterpillars. Japanese beetles can be controlled naturally or by applying bacillus thuringiensis or nematodes as well as hand picking. There are chemical methods as well, but these tend not to work well this Insect. Caterpillars should be hand picked. There are pesticides to treat caterpillars, but these will kill the good caterpillars as well as the bad.

Black Knight Butterfly Bush plants are looking very healthy.

I received the black butterfly last week. I have been watering them every day and the leaves look healthy. I look forward to planting them in the next month alongside my backyard deck.

Was expecting much better

The plant arrived healthy, smaller than what I thought, looks completely different than from the site. Soil half out of container, but that was FedEx's fault. Can tell the difference in care this plant was given compared to ones at the store, the soil type was very good versus the store, and plant had no brown. Plant is in the ground was planted upon receipt.
