Materials needed: last year's grape vines
Tools needed: hand pruners
: bucket or tub for soaking cuttings
When: late Winter of early Spring
Step 1: How many pieces to cut and the cutting details.
Start at the thick, cut end of the vine and continue to cut sections until the vine becomes too small in diameter. I usually don't use anything less than the diameter of a pencil. Aside the pieces you want to keep. Into another pile, cut the rest of the vine into sections for disposal however is appropriate where you live.
Tie your bundle of cuttings and store for use later in the year.
Step 2: Installing the Edging
To install, push one end of the first section 4-5" into the soil at the edge of your flower bed. Bend the vine and push the other end into the soil about a foot away, along the edge of the bed. A 12" guide block may help with consistency. At the middle of the first arch, insert the first end of the second vine section. Repeat the bend and insert the other end about 6-7" past the end of the first arch. Continue installing overlapping arches until your border is complete.
The vine arches can be saved from year-to-year but they will be brittle after storage. A good soaking will help but you should expect some breakage.
A bundle of cut vines and some help with installation might be appreciated by a gardener friend.
