Benefits of Winter Mulch: From the Desk of Sal Masullo

It has been said many times and it is true, "Timing is everything."

Sal Masullo, working hard to protect his clients' investments.NOW is the time to consider winter mulching. Winter mulch is a little different from regular shredded bark mulch. Winter mulch is an organic compost based mulch that provides many benefits for both new and established plantings. Considering the very dry fall we experienced this year, winter mulch makes even more sense as a simple, inexpensive way to protect the investment you have in your landscape. The root systems of your trees, shrubs and perennials have been under tremendous stress. Winter mulch will protect these roots through the cold days ahead.

 

Just like people, plants require supplementary nutrients. Healthy plants are better equipped to fight off pests, disease and extreme temperatures. The benefits of winter mulch:

          Insulates soil and minimizes the impact of extreme cold temperature on plants and their root system

          Minimizes root disruption from the freeze/thaw cycle by stabilizing soil temperature

          Feeds plants slowly, consistently and organically as it decomposes

          Reduces moisture evaporation from the soil (a key benefit this season)

In short, winter mulch is preventative medicine for your plants. If you would like more information regarding winter mulch or other helpful winter protection for your garden, contact our office and one of our landscape professionals will be happy to answer all of your questions.

Drought: A Cautionary Tale

It is fall and we are in a drought. While it may not seem so because the weather has cooled off, our plants need water now more than ever. Stressed trees are turning colors earlier than normal. If you notice that your plants have brown or wilted leaves, early leaf drop or stem dieback, your plant is calling for help. When stressed, plants are more susceptible to pests and disease.

We are used to seeing this in the high heat of summer, but drought can happen any time of the year. A deciduous (drops leaves for winter) plant can mitigate the damage because it will have no leaves to lose water through and essentially go dormant. It may also drop its leaves prematurely in defense during a drought. This winter will be especially harsh to our broadleaf evergreens due to moisture loss through their leaves. Conifers and broadleaf evergreens will drop some needles and leaves every year routinely, but substantial leaf drop means something may be seriously wrong.

An anti-desiccant spray can help. However, irrigating before the ground freezes will give them a much better chance to survive a dry fall and winter. A leaf with a bigger surface area will transpire faster than a leaf with a smaller surface area; therefore, broadleaf evergreens are more at risk. Even conifers such as pine, spruce and fir will lose water through their needles. If the plant loses too much moisture through its leaves, it can't stay healthy, and a unhealthy plant will fail. A plant will keep expelling water unless something is in place to stop it whether by the plant shutting the stomata by itself or with our help. An anti-desiccant (anti-transpirant) application can help protect the leaves by reducing the stomata openings. This application will also help protect the leaves from wind burn (see above right). The root system will be compromised if there is not enough water in the soil and if the soil is too dry it can erode away. If the roots are damaged severely, the plant could die. Protect your landscape investment!

From a recent interview with Long Island Pulse magazine, Tom Rodler, our president, says, "A good rule of thumb is to give a new plant about one inch of water per week throughout the fall." We are down 5 inches from our normal rainfall since June. You must be extra diligent, especially with new planting, to ensure your plants survival through the fall and winter.

Avoid stressing the plants even more during drought by refraining from pruning and transplanting. Mulch can help prevent water loss by evaporation from the soil around a plant, but if the soil is dry to begin with it is a futile gesture. Once the ground is frozen a plant can't take up any more water so protecting it now is important. DO NOT water at lower temperatures. Heaving will lift and damage root systems if not properly mulched, especially as the ground freezes and thaws throughout winter. We offer a winter mulch application to protect your plants against heaving damage, but don't apply it too late or clean it up too early. Some animals stuff themselves before hibernating in the winter and we need to prep our plants in a similar manner. A dry, windy winter could be the last nail in the coffin.
