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

THe quality of the product was fantastic but I received it 1-19-17 in Southwestern Pennsylvania. I ordered it 1-16-17 and expected to receive the butterfly bush in the spring. Fortunately the temperature was around 60F. and I was able to plant it. See how it does this spring and summer. Received in 3 gallon container, Bush was 15 X 15 green and growing very well packaged.



I've tried this same plant before from another online site and honestly it looked like **** and was way more expensive! The Planting Tree's bush looked beautiful and it continues to thrive in our landscape! I'm sticking with for future purchases!
