You should actually prune your spirea more than once a year, at least twice. Cut back the tips of the stems to the top leaf bud to give it a good trim after it flowers. The dead blossoms may be removed and a second bloom may occur. The shrub can be shaped to make it look like a tree.
If you have a lot of spires in your garden, you may want to trim them back to a more manageable size. If you don’t have much space to work with, it may be best to leave them as they are.

How far back can you prune spirea?
To keep the shrubs shaped and compact, trim back overgrown spireas that produced sparse foliage on the lower stems in the fall. To cut back each stem, you should be able to see the soil line. Do not fertilize more than once a year.
How do you prune spirea in early spring?
Before the leaf buds start to swell, you should cut the stems down to 4 to 6 in. tall. You can either cut one at a time or hedge clippers at the same time, and it doesn’t matter which way you do it. When you’re ready to harvest the buds, you’ll want to remove all the leaves and stems from the plant.
If you don’t have any leaves or stems on your plant, it’s best to leave it alone and let it grow naturally. But if you have leaves, stems, or any other part of your plants that you’d like to get rid of, remove it as soon as you can.
Can I cut back spirea in summer?
After the first flowering is the best time to grow spirea. The best time for a spring-blooming cultivar is late spring. If you see a lot of new growth, you may have over-pruned your plant. If you notice that the plant is starting to wilt, it may be too much pruning.
You may also need to cut back the number of leaves that are growing in the center of the stem. This is especially true if you are trying to grow a tall plant, as you will need more leaves in order to support the weight of your plants.
When should lilac bushes be trimmed?
As a general rule for all lilacs, they should be pruned immediately after they’re done flowering in the spring. Pruning after the current year’s flowers have faded will result in cutting off many of the new buds, since the next year’s flower buds are set right after the current year’s flowers have faded. How to Prune Lilac Flower Buds: Lilacs have a very short flowering period, so it’s important to prune them as soon as possible.
If you don’t do it soon enough, you’ll end up with a bunch of buds that won’t be able to bear the weight of a full-grown plant. The best way to do this is to cut the buds off at the base of each flower bud.
This will make it easier for the plant to take up the slack when it needs to flower, and it will also allow you to get a better look at what’s going on inside the flower. Once you’ve cut off all the bud tips, it should look something like the picture below. You can also use a pair of tweezers to gently pry them off, but be careful not to damage the flowers.
When should lavender be pruned?
Lavender can become ungainly if left to their own devices so it’s best to trim them annually in the late summer just after flowering has finished. The flower stalks and petioles should be removed from the top of the plant.
Plant in well-drained soil and allow the soil to dry out between waterings. Plant in a sunny position, away from direct sunlight, and keep the temperature between 15°C (59°F) and 25° C (77° F) during the growing season.
When should I cut back my clematis?
Prune your large flowering clematis during the spring, when the plant is still dormant. Cut back to a pair of healthy buds after removing any damaged, dead or weak stems. It’s a good idea to avoid heavyPruning at this stage as you might get less than ideal results.
Fertilize your plant with a mixture of 1/2 to 3/4 cup per gallon of water, depending on the type of soil you are growing in. You can also add a small amount of compost to the mix to help keep the soil healthy and prevent root rot.
What is killing my spirea?
One of the most destructive diseases of spireas is fire blight, which causes leaves and twigs to die back. The leaves die, hang downward and cling to the twigs. The shrubs’ appearance is ruined by dying branches during the summer. Blight is caused by a fungus that thrives in warm, moist conditions. The fungus infects the roots of plants, causing them to wither and die.
When the fungus enters a plant, it causes the plant’s leaves to turn brown and eventually fall off. In some cases, the disease can spread to other plants in the same area. It can also be spread from plant to plant by wind, insects, and other means.
