Large Limb Removal Tips

There are a number of reasons to remove large limbs from mature trees. The three most common reasons are to either remove dead wood, to keep limbs from interfering with one another and rubbing or growing together, or to keep the tree from having narrow crotch angles. (“Narrow crotch angle” is not a very charming phrase, but it simply refers to branches that grow at angles less than 45° relevant to the trunk.)

Removing tree limbs larger than four inches in diameter should be done with care. Three cuts per limb are often needed to avoid tearing the bark down the side of the tree’s trunk.

  1. Make the first cut on the underside of the branch about 18 inches from the trunk. Undercut one-third to one-half way through the branch.

  2. Make the second cut on the topside of the branch an inch further out on the branch; cut until the branch breaks free.

  3. Before making the final cut, identify the branch collar. The branch collar grows from the stem tissue around the base of the branch. Make pruning cuts so that only branch tissue (wood on the branch side of the collar) is removed. Be careful to prune just beyond the branch collar, but don’t leave a stub.

It is important to take your time whenever working with power equipment and trees in your landscape. You usually only have one chance to get the cut right and you don’t want to injure yourself or ruin your tree.

Gardener’s To Do List for December

Gardener’s To Do List for December

growing-daffodilstree pruningThough the calendar says December, the weather in Northwest Florida fluctuates between winter and spring temperatures. The nice days are wonderful opportunities to accomplish many of those outside landscape chores in preparation for spring.  But, it is also a good time to start planning for next month’s colder temperatures.  Since we don’t experience frozen soil, winter is the best time to transplant hardy trees and shrubs.  Deciduous trees establish root systems more quickly while dormant; versus installing them in the spring with all their tender new leaves.  Here are a few suggestions for tasks that can be performed this month:

  • Plant shade trees, fruit trees, and evergreen shrubs.
  • Plant pre-chilled daffodil and narcissus bulbs (late December/early January).
  • Do major re-shaping of shade trees, if needed, during the winter dormancy.
  • Water live Christmas trees as needed and water holiday plants such as poinsettias as needed.
  • Check houseplants for insect pests such as scale, mealy bugs, fungus gnats, whitefly and spider mites.
  • Continue to mulch leaves from the lawn. Shred excess leaves and add to planting beds or compost pile.
  • Replenish finished compost and mulch in planting beds, preferably before the first freeze.
  • Switch sprinkler systems to ‘Manual’ mode for the balance of winter.
  • Water thoroughly before a hard freeze to reduce plants’ chances of damage.
  • Water lawn and all other plants once every three weeks or so, if supplemental rainfall is less than one inch in a three week period.
  • Fertilize pansies and other winter annuals as needed.
  • Protect tender plants from hard freezes.
  • Be sure to clean, sharpen and repair all your garden and lawn tools. Now is also the best time to clean and have your power mower, edger and trimmer serviced.
  • Be sure the mower blade is sharpened and balanced as well.
  • Provide food and water to the area’s wintering birds.Spreading-Mulch

This Fall: Pause Before Pruning Spring Blooming Shrubs

As fall approaches, our spring blooming shrubs such as gardenia, spirea and azalea begin to look unkempt and overgrown. That means it is time to give them a severe pruning to get them ready for winter, right? Not so fast, take a minute to understand the growth habit of each species before diving in with the pruning shears.

Azalea:

Many do not understand that annual spring azalea bloom could be sacrificed completely by pruning spring blooming azaleas at the wrong time.

Pruning traditional azaleas in the fall will result in a loss of spring bloom the following year because most bloom on previous years’ wood. This means that they flower on growth put on throughout the previous growing season. If a gardener removes the previous season’s new growth, they are removing the blooms as well.

So, when is the proper time to prune azaleas? The ideal time to prune is directly after the spring bloom. This will give the plant enough time to generate abundant new growth, thus maximizing bloom next spring.

Even the developers of the Encore Azalea, a new repeat blooming type, recommend pruning as soon after the spring bloom as possible to maximize bloom set for the following year.

For more information on pruning azaleas or on general azalea culture, please read the UF / IFAS publication Azaleas at a Glance or check out the Pruning Azalea page on Gardening in a Minute.

Gardenia:

Gardenias don’t need much pruning except to remove any dead or non-productive wood, to help them remain bushy, and to remain the same size as other plants in the landscape. Choose a cultivar that will mimic the size of other shrubs, not one too large for the area. Pruning should be done as soon after the summer bloom as possible. Pruning after the beginning of fall will reduce the next year’s bloom production.  Know your cultivar. Some cultivars of gardenia flower on new wood as well as old, while some flower on old wood only.

Spiraea:

Regarding spiraea, prune after the bloom as needed. The closer to the late summer or autumn, the greater negative effect pruning will have on bloom quality since spirea set their bloom in early autumn.

I hope this article prevented a few pruning disasters as well as started a thinking process for the act of pruning your landscape plants.

 

It’s Wise to Prepare for Storms

It’s Wise to Prepare for Storms

Tropical storm season officially ends November 30. I’m not predicting a storm but even with our average winds during a typical thunderstorm, you’d be wise to prepare.

Falling trees and flying landscape debris during a storm can cause damage. Evaluate your landscape for potential tree hazards. Pruning or removing trees once a hurricane watch has been announced is risky and tree trimming debris left along the street is hazardous.

Now is a good time to remove dead or dying trees and to prune decayed or dead branches Also inspect trees for signs of disease or insect infestation that may further weaken them.

Professional help sometimes is your best option when dealing with larger jobs. Property damage could be reduced by having a professional arborist evaluate unhealthy, injured or questionable trees to assess risk and treat problems. Hiring a certified arborist can be a worthwhile investment. To find a certified arborist in your area contact the International Society of Arboriculture (ISA) at 217-355-9411 or at www.isa-arbor.com. You also may contact the Florida Chapter of ISA at 941-342-0153 or at www.floridaisa.org.

Consider removing trees that have low wind resistance, are at the end of their life span or that have potential to endanger lives or property. For example, laurel oaks are relatively short-lived, usually showing considerable dieback as they reach 50 years. They tend to lose their strength and stability faster than most other oaks and have low wind resistance. Consider removing a big, old laurel oak within falling distance of your home before the next storm.

Tree species with the lowest wind resistance include pecan, tulip poplar, cherry laurel, Bradford pear, southern red oak, laurel oak, water oak, Chinese tallow, Chinese elm, southern red cedar, Leyland cypress, sand pine and spruce pine.

Pine species vary in their wind resistance, usually with longleaf and slash pines showing better survival rates than loblolly and sand pine. However, when pines become large, they may cause damage if located close to homes or other valuable structures.
