#18 Tip Hedges

Hello Everyone:
And Happy 150th BC Day! I hope you all are out exploring the many venues available this holiday weekend.
As promised last week, I would like to spend time on hedges from my own personal experience and from Dora's.
Dora talks in length about cedar and cypress material. All these have a shallow root system which allows you to spread their roots in a fan shape and bury them about 3 inches deep. The purpose as Dora states is: "to start them growing down away from the heat and also lets the water run out to the side roots." It has been my experience when planting and continuing on in its early seasons, tipping your plant—both tops and sides—whether bare root or container grown; will cause the hormones to travel down and begin branching into a thick screen.
"Cotoneasters have to be pruned drastically for the first three years with secateurs. They really are adapted for tidy hedges." (Note: the use of hedge clippers damage the flower or fruit stage, but secateurs give you the control to cut right down to the flower or fruit branch).
"Quince- Japonica- can be trimmed at 5 or 6 feet for a compact hedge, but will blossom more profusely if left informal."
"Berberis will grow to a very compact 3 feet. Aside from berries, and adding to its usefulness, this plant is quite thorny." If you want an area of your garden free of access, berberis will stand up to even the most staunch aggressors.
Box Hedges are those very formal, small, dense, leathery, deep greens that you often find in topiary-type gardens. They are slow growers that will reach a height of about 10 feet in 15 years, with small yellow flowers, blooming in late autumn. Dora states in her notes that if you only allow these to grow 4 inches a year, the density of the hedge will far outweigh its lack of height. I have seen these small hedges used as background mazes to offset perennial or annual beds.
A lot of people will disagree with me, on this next selection, but from many years experience, planting a laurel hedge is very cumbersome in its upkeep. Their height is endless, which is a great feature, but be prepared for some very heavy pruning. Required at least twice a year, the diameter of their stems will require a lot of muscle power and the tools to go with it. We used chainsaws to top these hedges and as the leaves have a tendency to grow flat, the use of hedge trimmers—for the sides, make it quite a challenge. If you are convinced of laurel hedging, which is a fast grower, be prepared to invest some time and possibly money in the later years as it matures.
As an aside—there were countless times as a landscape gardener that we encountered quite mature laurel hedges. Due to their vastness as a broad grower, they usually cross property lines. The benefit of blocking in your yard is beneficial for both you and your neighbour. If you don’t like your neighbour, though, this becomes a problem. We were instructed by our customer to prune so many feet off their hedge, only to have the neighbour complain and only want inches taken off on their side!
The result: A hedge which resembles stairs as its top would be two different height levels across.
One last note, remember always to have your tools sharpened on a regular basis, as this will ensure a clean cut.
Next time, in our last of our four part series, we will digress a little and touch on the odd and ends of gardening.
Until then, happy planting!
