Growing a Forsythia Hedge from Cuttings?

We grew a 70 foot long hedge from cuttings. We cut branches from bushes that grew through our fence, after they were through flowering in the spring. We were told that we had to use short cutting but we used 4 foot long cuttings. We took all the leaves off the bottom of each stem, dipped them in root hormone and planted them 10 stems to an 8 inch deep hole filling it in with peat moss and top soil. We put a soaker hose down the length of the entire row of plant cuttings. We did them all in the same day. We were slap happy near the end. We planted them about 12 inches apart. They all took.

The only regret was planting them too close to out chain link fence because they grew very wide through the the fence and have to be cut back every year. They grew over 6 feet tall by the next spring and are now kept at about 8 feet tall. They will grow thick and straight if you trim a few inches off all sides every once in a while. My mother in law said we had to smash the ends with a rock first but by about the 10th hole we just shoved them in the ground. It saved us a lot of money making our own plants. We made new plants with all out plants, like hosta, daylilys, boxwood plants etc.
