Pruning:

its flower buds in later summer and then flowers in late

mid-July to mid-August. Cease pruning in mid-august to
allow time for the flower buds to form prior to winter.
As a
young plant it is best to prune or pinch your plant in order
to build a full bodied, well branched plant. If the
plant is leggy when you purchased it, shear the plant back
hard by 1/3 to 1/2 its original size. Once it puts on an
inch or two of growth, pinch the branch tips to remove just
the growing tip. This tip controls branching. Once it
is removed the buds below it will turn into stems. Once
these new branches grow an inch or two, pinch the tip out
again. You can repeat this throughout the first growing
season as you are tending your garden. Although you
will sacrifice one year of bloom, this technique results in
a well branched, full bodied plant that will have more
flowers in subsequent years. The second season in the
ground, repeat the pinching practice (or lightly shear) up
until mid-August. Cease pruning and pinching to allow
the flower buds to set.

alkaline.
