It’s a bother trying to remember when to prune what. Which is why this handy posting is great for me…and anyone else who owns these plants. Let’s do this:

Roses

1. Kazalink

Season to Prune: Summer

Type: Damask Rose

Blooms on old wood; prune after flowering

This plant can get over 10 feet tall.

2. Seven Sisters – Climber

Season to Prune: Summer

Once blooming climber.Should be tied to hang in an arch over a fence: Will produce much flowers.  Vertical growth inhibits flowers.

Prune after first bloom.  Will encourage new growth.

3. New Dawn Rose – Climber

Season to Prune: Fall

New Dawn flowers on new and old wood.  So just leave it alone.  Prune for size and shape in the Fall.

“New Dawn reblooms. Removing the spent bloom, called deadheading, should be done in the smallest possible way with this rose if you want the best rebloom. The farther down the flowering cane you cut, the longer it will take to rebloom. Remove the least possible amount of rose, just the flower head, unless, of course, the rose is in the way. If that is the case, tie it!

New Dawn is a Large Flowered Climber and will bloom and old and new wood. However, for best rebloom this year, you should deadhead as lightly as possible. Hedge trimmers won’t do it lightly.”

Climbers: Clematis

Group 1: This group contains some of the most vigorous clematis. When used to cover large areas, such as walls or fences, no pruning is required. If, however, space is limited some pruning may be necessary. If you do need to prune a Group 1 clematis this should be carried out as soon as flowering has finished. This allows the plant to produce some new growth which will supply the flowers for the following year.
Group 2: This group contains the early and mid-season large flowered hybrids which usually begin flowering before the end of June. Although no regular pruning is required, you may wish to remove any dead tips from the stems. This will keep the plant looking tidy. In late February or early March, working down from the tips, follow each stem until you come to a pair of live buds. Remove the end of the stem by pruning just above this point.
Group 3 This group contains all the late flowering species and hybrids. Although these varieties will flower if left unpruned, they will soon become bare at the base and flowers will be produced well above head-height. This is ideal when growing clematis into a tree, but for general use hard pruning is recommended. Each February, prune all stems back to approximately 30cm (12″) from ground level, cutting just above an old leaf joint. New growth will soon appear, resulting in a plant whivh is green from top to bottom and with flowers at a more acceptable height.

1. Comtesse De Bouchaud

Season to Prune: Spring

Clematis Pruning Group: Light prune (Group 3)

2. H J Young

Clematis Pruning Group: Light prune (Group 2)

Climbers: Wisteria

Wisteria Lawrence

Season to Prune: Early Spring then later in Summer

“The first pruning should be in early Spring before the new flower buds are too developed. The stems of a wisteria vine can grow to be as thick as a wrist so careful pruning with a pruning saw may be required. It is best to try to open up the previous years’ growth to make room for new shoots. The second pruning should be done in Summer, this is more of a tidy-up process than anything else. If it is necessary to severely prune a wisteria remember the newly pruned vine will burst into growth and will send shoots in all directions. It may be necessary to prune some of these also.

Hydrangea

1. Cityline Rio – Macrophylla “Ragra” (provenwinners.com)

Season to Prune: Summer

“Bigleaf hydrangea should be pruned as soon as the flowers have faded. You should begin to see new growth coming in from the base of the plant. To keep the plant vigorous, selectively prune out the dead and weaker stems, both old and new. Don’t prune out all the old wood, since this is what will keep flowering as the new growth matures.”

Pruning: If pruned in winter or spring, you’ll end up cutting off the flower buds.  These grow in during the fall.  So prune in the summer after the flowers start to die off.

2. Cityline Vienna – Macrophylla “Vienna Rawi”

Season to Prune: Summer

Same as above

3. Peegee – Paniculata Grandiflora

Season to Prune: Winter or Spring

Flowers on new growth.  Prune in Winter.

Pruning: Right before winter, cut off the flowers (They look ugly in winter), and thin out heavy growth.  These can grow to over 25 feet, so be aggresive.  Peegee can be cut down to the ground, they will grow back.

Misc

1. Russian Sage

Season to Prune: Spring

“Prune Russian sage back in the spring after new growth has emerged. Cut back to the lower three to four shoots to encourage more shoots to form from the base.”

2. Rose of Sharon

Season to Prune: Spring

Rose of Sharon flowers in mid to late summer, it sets its flower buds on the current season’s new growth.

To encourage the shrub to produce more flower buds, prune the plant in late winter before it breaks dormancy.

4. Lilacs

Pruning should be done immediately after the flowers have died off. Cut small suckers and shoots at or near ground level, or where it comes out of the main trunk. Leave a few strong and healthy new stalks each year, especially if you are planning to trim back old wood.
