Drooping butterfly bush
I planted two butterfly bushes several weeks ago. They appear to be healthy with abundant flowers and foliage. However, the branches are drooping to the point where they are almost touching the ground. All other butterfly bushes I've seen have strong branches that grow straight up. Could this be the particular species or something else? I don't know which species this is. The flowers are magenta in color. Thank you.
Newly planted perennials need daily water for the first two weeks and then you can back off, but still make sure they are receiving enough water; especially in the first few months.
Also make sure the soil is draining well, too much moisture will cause the roots to rot out.
Also make sure you are not watering down into the crown of the plant. Water the soil around the plant.
