Should a License Be Required to Carry a Hedge Shears?

What was not forseen in the advent of desert landscaping was the dramatic change in pruning techniques brought in by the landscape industry. Hand pruners and loppers were gone. Hedge shears were in. I was heavily involved in bringing good desert landscaping into Las Vegas in the 1980’s.  It was part of my job. One of the big advantages touted for desert landscaping was the reduction in maintenance by about 30% because lawns were either removed or shrunken in size. Lawns represented the most maintenance in a landscape. What was not forseen was the dramatic change in pruning techniques brought in by the landscape industry. Hand pruners and loppers were gone. Hedge shears were in. Nice looking, formal hedge. This is where the hedge shears should be used. The top of the hedge should be slightly narrower than the bottom. This gives the larger diameter wood at the base a chance to maintain leaf cover for a longer period of time and allows for better light reception at the base. Hedgeshears Logic. I have never understood the logic of using a hedge shears to prune anything but a hedge. But they are. Commercially it fits the “blow and go” logic of the current landscape industry. Manually operated hedge shears by Corona. I like Corona shears of most types, and even their hedge shears, but it is over-used in commercial and home landscapes. Even Corona would not endorse the extent to which it is used. You carry a hedge shears around and you use it to make everything look like a ball. The “trimmings” from the shrubs are picked up and hauled off to the landfill (at least in Las Vegas). Landscape shrubs about three years into hedge shearing. They have started to become “twiggy” and their multiple trunks are becoming exposed. If there is anything to “blow”, the guy carrying the gas engine-driven, cacophonous blower comes in some time later and finishes the cleanup. Landscape workers will start “blowing” on commercial properties where noise problems are not much of a problem, in the dark with headlamps, at 5 am or earlier. Some used have “night vision” capability. Arguably, these are the “Rambo” landscaper types (aka like the camos). One headlamp preferred by landscape workers Landscape in the early stages of hedge shearing. Some of these can still be corrected. The big advantages for landscape service companies using hedge shears is that it requires carrying only one piece of equipment, very little training required so almost anyone can do it, the results of hedge shearing are immediately seen by the customer and it requires numerous repeat shearings during the season. Disadvantages. The disadvantages to the customer are not seen at first and sometimes not cared about. Plants that produce flowers on new season growth, like Texas Ranger and oleander, have their potential new flowers removed. The plants are neatly “hedged” but flower production is later in the season than normal and usually very sparse because new growth is continuously removed. Second, most plants pruned with hedge shears are pruned into an unnatural shape. This means more work is needed to keep them in this shape (repeat shearing during the season). Third, the aesthetics of these plants are ruined in about five years. Shearing makes them “leggy” so that you see alot of bare, thick stems at the base and they lose their leaf cover. Basically they get ugly. At this point most plants cannot be “corrected” and they must be replaced. If replacing plants every five years is in your business plan then hedge shearing is for you! This is what eventually begins to happen to shrubs that are continuously hedge sheared. Large stems at the base get larger and larger and lose their “ability” to produce shoots that can carry leaves. Fourth, bare wood on the stems at the base is open to damage from sunburn and infestation by borers (if they are susceptible to borers). Correct pruning of shrubs that are not to be used as a formal hedge is near the ground, removing 1 to 3 of the oldest stems if there are only a few of them. More than this may be removed if there oodles of these stems. Plants will show you where to cut them if you just look. This is oleander for example. At the base of oleander there are some “suckers” aka watersprouts, emerging from some short stubs that were left from last year’s pruning. This is a very good sign that if you were to prune oleander stems low to the ground that they will sucker and send up all new shoots. This is a closeup of the base of the very same shrub. Notice the cut stub left from last years pruning cut. This person had the right idea but cut the wrong stem!. Leave the young ones. Cut the oldest ones the same way and let them sucker up to fill in the bottom. Do this on one or two of the oldest stems every other year and you will fill the shrub with blooms top to bottom and you will not see any of the base of the plant. Two cuts = ten seconds. Pickup time = ten seconds. Do not use the hedge shears on this plant. If there are alot of stems then follow the 1/4 rule. Remove about 1/4 of the oldest stems every 1 to 3 years depending on how juvenile you want your shrub to be and how tall you want it. This type of pruning is needed from 1 to 3 years depending on how vigorously the shrub grows. level and pruning is every two to three years. If you are not sure what will happen to the plant cut just one stem back near to the ground and see what happens. If it suckers up, do a couple more. It will not be too late. You could do this easily until about March or even April. Cleanup is easy. You collect

Reshaping Crapemyrtle After Bad Pruning

Q. There are 3 crepe myrtle in the back yard. One is very nicely shaped the other two were beside a patio overhang and side limbs were apparently removed to the height of the patio cover.  So we have 2 very TALL 20 ft  skinny trees with some green leaves at the top. I would love to prune the trees so they would grow out as opposed to up, thereby creating an umbrella shape to provide shade. Can I bend over the top branches and wire them to a more curved shape?  A. That is very unfortunate that these trees were pruned in this way.  I can understand your disappointment. Once that these lower limbs were removed you are correct, the form was destroyed. I doubt very much that any new growth would occur in the lower canopy area from larger diameter limbs. So you are right, you would be able to pull some of these larger diameter limbs into position to form a more rounded canopy. Let’s talk a little bit about how to do this. What you will try to do is to train the trees rather than prune them. Training is a different concept from pruning.  Pruning is the physical removal of plant parts. What you want to accomplish here is encouraging the plant to grow into a different form by manipulation that does not involve pruning or removal of plant parts in the beginning. You will be bending the branches into a different position that is more eye-appealing. This involves pulling or pushing existing growth into areas where it does not want to grow. When you pull or push plant parts into different positions, this will cause the tree to respond to this change in its shape. After this response occurs over the next couple of years , you will then begin pruning to maintain and encourage this change in its form. Timing when you pull  these branches into place will be somewhat critical. You will pull them into place when they are supple and can bend easily without snapping the wood. You are lucky. Crape myrtle bends well. The wood is sometimes used for bow-making. Bending the branches is best when the sap is flowing in the spring. Your visual cue for this is when you begin to see new growth this spring beginning in February. Do not wait too long or you’ll miss this window. I would gauge this opportunity from early February to about mid-March. The easiest would be to use non-abrasive cord, such as cotton clothesline, loop it around the branch you want to pull into place, pull it to the position you want and stake it to the ground. This position can be at any angle you want and in any direction you would prefer. Leave it tied in place for one growing season. That is enough. Once the branches are pulled and tied in place you will see a change in how the plant grows. You will see more growth coming from the upper sides of the bent limbs. This is a response of growth to new sources of light. We call this type of growth phototropic. Roots grow away from light and called negatively phototropic. Less growth will occur from the bottom sides of the limbs because there is less light there than before. As this new growth occurs from the upper sides of bent limbs is when you can begin pruning the tree — if you want. The branches that grow will “fight it out” for light and grow accordingly. You can remove wood if it is objectionable to your sense of proportion and balance. In most cases your pruning cuts will be “thinning cuts” rather than “heading cuts”. Thinning cuts remove entire stems or branches back to a crotch and do not leave any stubs or partial stems or limbs. Leave the strongest and healthiest growth if it is in a place that you like.

My Beautiful Italian Cypress Was Butchered By A Tree Service

Q. HELP! My 25 year old beautiful Italian Cypress have been butchered by a tree service hired only to top them. How can I save these once beautiful trees. I am sick. I have been hosing them down every morning and deep watering them also.They have many brown areas that have been chopped to the limbs. There is a lot of green but, they do not look well. I can take a picture and send it if it will help garner some advice. Overwatering or overfertilizing or both can cause excessive growth and “floppiness” A. You can send me a picture but frequent water may in fact be hurting the tree. Go back to deeper (12 to 18 inches deep) watering occasionally. Right now perhaps not any more often than once a week at the most.             You can also try to apply some fertilizer lightly, one application only. It does you no good to fertilize over and over. It will put on new growth mostly now and slow down as the summer is concluding.             If the landscape company has cut back the stems into bare wood it is very possible it may not recover. If it does recover because they did not cut too deeply the recovery will be slow. Unfortunately this is a problem when they prune with hedge shears which is ridiculous.              Frequent watering may cause some succulent growth to occur which will not be sturdy and this growth will be “floppy”.             I wish I had better news but you will have to wait and see how the plant responds. But in the meantime water and fertilize normally; water once a week and fertilize once or maybe twice this season. That’s all you can do. Let me know how it turns out.
