Winter is the ideal time to prune most shrubs and trees
Correct pruning is a landscape practice that can enhance the health, vigor and aesthetics of your trees and shrubs. In this blog, we are discussing five advantages to pruning in the winter: [Read more…]
Benefits of Proper Mulching
Good tree maintenance is common sense – it is what trees need to flourish in nature. In the wild, the forest floor is naturally covered with a layer of decomposing leaves, twigs and other plant material. In urban settings, the most common mulch is made of wood chips of varying types and sizes. [Read more…]
Winter is the ideal time to prune trees and shrubs. The type of pruning depends on what each tree needs. Here are the basic types of pruning that we perform. [Read more…]
During dreary winter days I envy a plant’s ability to go dormant. I’ve considered putting a sign on my office door stating, “Dormant – do not disturb until spring”.
This time of year it is often recommended to spray “dormant oil” to control insects on everything from fruit trees to lilacs. But is it just any oil sprayed when the plants are dormant? Some commercial dormant oil sprays are refined from petroleum oil. But Dos Amigos Landscaping uses an eco-friendly horticulture oil made from Cottonseed Oil. Unlike home remedies, commercial spray oils have an emulsifier added to allow the oil to mix with water, so they won’t be damaged by rain.
Applying “Dormant Oils” kills exposed insects and mites by either suffocating them (covering up breathing tubes) or by directly penetrating the outside cuticle and destroying internal cells. Spraying dormant oil after bud break and leaves have emerged will still control the pests, but it may kill the young leaves or cause leaf edges to turn black if the correct oil is not used at the proper rate. So it is best to apply these oils in the dormant season—here in Virginia that means between February 1st to March 15th, with variability for the specific weather pattern of any particular year.
Dr. Phil Nixon and Dr. Raymond Cloyd of the University of Illinois outlined the benefits of making an application of dormant oil.
Advantages include:
(1) a wide range of activity against most species of mites and scales, including some activity on eggs;
(2) minimal likelihood of insects’ or mites’ developing resistance;
(3) generally less harmful to beneficial insects and mites than other pesticides
(4) relatively safe to birds, humans, and other mammals.
Disadvantages of using dormant oil are:
(1) potential plant damage if incorrect oil is used or used at improper rate during the growing season and
(2) minimal residual activity to kill new pest infestations.
Dos Amigos Landscaping can apply “Dormant Oil” to your important landscaping shrubs. Holly, Boxwood and Azaleas often benefit from this treatment. We have the equipment to spray upwards from underneath the plant, which makes it more effective since many of the pests hide on the underside of the foliage. The homeowner does not have to do a thing. Just contact us, and we will stop by your property to inspect and assess your landscaping plants. We will provide a proposal, including any remedies for other issues we may have identified when inspecting your valuable landscape trees and shrubs. And then schedule the treatment at the optimum time.

After the initial pruning at planting, hedges need to be pruned often. Once the hedge reaches the desired height, prune new growth back whenever it grows another 6 to 8 inches. Prune to within 2 inches of the last pruning. Hedges may be pruned twice a year, in spring and again in mid-summer, to keep them dense and attractive. Prune hedges so they’re wider at the base than at the top, to allow all parts to receive sunlight and prevent legginess.
Every year remove up to one-third of the oldest, thickest stems or trunks, taking them right down to the ground. This will encourage the growth of new stems from the roots. Once there are no longer any thick, overgrown trunks left, switch to standard pruning as needed.
Deciduous shrubs that have multiple stems (aka, cane-growth habit), and that have become very overgrown or neglected can be rejuvenated by cutting all canes back as close to the ground as possible in early spring. That season’s flowers may be sacrificed but the 
benefits from bringing the plants back to their normal size and shape outweigh this temporary “collateral damage.” This pruning technique works best for shrubs such as overgrown spirea, forsythia, cane-growth viburnums, honeysuckle and any other multiple stemmed shrubs that are otherwise healthy. Within one growing season, these shrubs will look like new plantings, full and natural shaped.
With few exceptions, evergreens (conifers) require little pruning. Different types of evergreens should be pruned according to their varied growth habits.

We all know that some plants thrive in the hot sun and others prefer shadier spots, but what about … [See More...]
