Growing Requirements for Butterfly Bush Plants
Butterfly Bushes will grow in almost any type of soil but perform best if they are planted in moderately fertile, moisture retaining and well drained soil.
Buddleia plants should be grown in full sun or light shade.
Water regularly. Butterfly Bush plants will tolerate periods of drought,
but not boggy soil.
Pruning Butterfly Bush Plants
Remove spent flowers promptly and regularly for a longer lasting flower display.
Pinching out the tips of new top growth will promote
a more compact and bushier shrub.
Buddleia plants bloom on new growth.
They should be cut back to strong new buds near the ground in early spring,
after the last frost, but before new growth begins.
Propagating Butterfly Bush Plants and Growing them from Seed
Butterfly Bush plants can be propagated with semi-ripe cuttings taken during the summer
Buddleia davidii seeds can be sown in the garden during late spring and summer months,
up until two months before the first frost.
Seeds that are started indoors, in early spring and kept at 75° will germinate in about 20-25 days.
They may produce flowers during the first fall.
