Properly prune those shrubs
The one thing you can't do with a bad haircut is uncut it, so you just have to wait for it to grow out before you can fix it. That's how expert gardeners view the art and science of pruning a shrub.
For many, it would be a perfect world if pruning shears came with instructions. Now, that's not to say it takes a PhD in horticulture to know how to prune. The basics are actually very easy to learn.
*Know What You're Pruning -- Before you make your first cut, look carefully at your garden and identify what you're going to be pruning. Check with your garden store or use the Internet to identify them if you don't already know. You want to learn how the shrub should look so you can prune it to maintain that natural shape.
*Cut Back to the Branch - Always cut back to a bud or branching point. Never leave a long stub. A stub will not only look ugly, but it will also invite insects and disease that could cause long term problems.
*Cut the Dead Weight First -- Before you cut anything else, cut out the dead or broken branches. Sometimes removing a dead branch will leave a big gap, so by doing them first, you'll be able to tailor the rest of your pruning to compensate for that gap.
*Crossing Over -- After you eliminate the dead branches, next you want to target crossing branches or branches that are likely to cross in the future. Once they start rubbing against each other, they'll leave a wound that will invite insects and disease, so you want to eliminate that threat.
*Cut With the Flow - Finally, cut out all branches that are not going in the natural direction of the plant. This is good for the health of the plant, as well as the look of your garden.
After you master the basics, you'll discover that your garden will have a crisp, clean look to it and your neighbors will not think your shrubs are having a bad hair day.
Your garden will grow in accordance with how you prune it and you'll do less work over time to maintain it. That means fewer hours of outdoor labor, and more hours of enjoyment.
