Pruning Miniature Lilacs

Thanks for contacting Toronto Master Gardeners. Dwarf syringa (lilacs) need little pruning. Promptly remove the blossoms after they completed blooming. Cut old flower clusters at their base; just above the two new shoots that angle out from the stem that ended with the old flower.  New shoots will grow over the summer and form the blossoms for the next spring. Also remove any dead or diseased branches.  Over time the oldest stems can be pruned to the ground.  This allows younger, stronger stems to grow.
