Fall Fertilization: Your trees will thank you in the Spring.

IMG_7052Why Fertilize in Fall?

Late September through early October is a great time to fertilize your trees and shrubs because a good dose of nutrients will help them stay nourished, protect against diseases and support root development throughout the dormant months of winter.  Fertilizing a plant or tree right before winter months will also support healthy new growth in the early spring as the nutrients stay present in the soil for the roots to absorb for several months.  This year, we have experience extremely warm temps in fall which has put the trees under stress.  When the temps change drastically from cold to warm (90 degrees in Septemeber!) they need a little energy boost.

Our Fertilizer

Here at Emerald Tree & Shrub Care, we have tried a plethora of different fertilizers and have to say, we found one product that can do the work of many.  Biochemists at Growth Products have created the perfect mix of essential amino acids, sea kelp, humic acid, yucca extract, rooting hormones, fermented extracts, vitamins enzymes and more! They work together to boost each others beneficial properties and have proven to:

  • Aid seed germination
  • Improve rooting
  • Feed beneficial soil microbes
  • Improve plant physiology
  • Reduce excess salinity in soils
  • Improve a soil’s nutrient holding capacity
  • Reduce environmental stress

All of that AND it’s 100% Organic.

How to Fertilize

The proper way to fertilize is to inject the formula directly into the ground where the feeder roots are located.  Feeder roots can be found along the drip line of a tree, which is the circle that trims the width of the crown on the ground. Imagine the tree like an umbrella, the drip line is where all the water droplets will run off and meet the ground, this is where the maximum amount of nutrients will be absorbed.  A needle like the one pictured below is hooked up to our fertilizer solution and inserted into the ground to feed the tree the necessary amount based on it’s size.  There are times when underground wiring or irrigation prevent us from doing a ground injection, and in those cases we will just give the drip like a nice hefty soak.  The problem with a ground soak is that you can never be sure the nutrients reach the roots below.  Sometimes the ground is compacted, or the roots are deep down and that is why we prefer to use a needle and inject our fertilization.

Mushrooms Growing On My Trees, What Does It Mean?

armillaria-mellea9

Often times, after heavy periods of rain, some trees may sprout mushrooms at the base of the trunk.  They grow fast, and are a very important sign that something could be wrong with your tree.  Mushrooms are known as fruiting bodies; meaning they are a specimen that produces spore of a fungus.  There are many different types of fungus, but the one to be most wary of, with regards to your trees, is the Armillaria Species.  Armillaria is a parasitic fungi that causes root rot and could prove deadly to hardwoods like Oak, Elms, and Honey Locust Trees.

A couple of ways to identify these fruiting bodies, which are often called honey mushrooms, is to examine their appearance.  If the mushrooms on your tree are yellowish in color, with a white rim around their stems and a flat shaped cap, you likely have Armillaria.  A second way to confirm if your mushrooms are honey mushrooms is their smell. Honey Mushrooms got their name because of the sweet smell they let off.  Unfortunately, there is typically very few signs of this root rotting fungus until the mushrooms sprout, and by then it is too late.  Your tree might appear completely healthy, but that does not mean you can ignore this alarming symptom.  Armillaria invades the roots and wood of the tree, extracting all the nutrients for it’s own survival.  Once infected, the structural integrity of the tree is completely compromised and there is rarely an option for treatment, removal being the only solution.

It’s very important that you call a certified arborist for an inspection as soon as you spot mushrooms on the base of your tree.  One infected tree can pose great danger for the rest of the trees on your property.  Special precautionary steps, such as removing as much of the roots as possible, should be taken to avoid the spread of this invasive pathogen.

The Scoop On Mulch

MulchOptions

What is mulch?

Mulch is a layer of material, usually organic, that is spread on top of the soil’s surface to provide various benefits to the soil, plant and overall garden.  Mulch can be made of many different materials, some of the most common forms are:

Woodchips and Shredded Bark

Plain old wood chips that are leftover from stump grinding or other tree work can make for a very natural looking mulch.  They typically take between 1-3 years to decompose, and sometimes can compact in the process blocking water and oxygen from the roots of the plant.  Another thing to note, is that when hardwood mulches break down they make soil more alkaline (raising pH), which should be taken into account when mulching around acid-loving plants.  You may need to use an acid fertilizer or add sulfur to compensate.

Dyed Bark Mulch

This is the most common mulch for homeowners because of it’s neat appearance and rich color way options.  It is not entirely the same as straight shredded bark though, because it generally has non organic material mixed in and will not decompose and nourish your plants like plain old shredded bark will.

Compost

If you want a mulch that adds loads of nutrition and organic matter to your plants than you should consider composting. It takes about one year to decompose, and is a very economical and environmentally conscious mulch option.  Even if you don’t do your own composting at home, many municipalities have started to compost and give it back to local residents for free or a minimal charge.  Compost can also make for a great additive to soil or alternate mulch material.

Cocoa Hull Mulch

This is not only one of the better looking mulch options with it’s rich deep color, sniff sniff, it also carries with it a smooth and sweet chocolatey scent.  Although it is one of the pricier options, it has a very slow decomposition rate and it’s fine texture make it very hard to blow away.  One thing to note, cocoa mulch is proven to be poisonous to dogs and cats.  The caffeine level is such that if a dog consumes as little as 6 ounces it could be lethal.

Stones and Pebbles

Landscape stones come in a variety of different shapes, colors and sizes and provide a more formal polished look to a garden.  The main pros are that they are long lasting (forever!) and do a fantastic job at blocking weeds. One thing to consider, is that because there is no decomposition happening, your plants won’t have the opportunity to absorb the additional beneficial nutrients as they do with organic mulch.  Also, they come with a high price tag and are heavier and result in a higher installation cost.

What are the benefits of Mulching?

Mulching provides many benefits to your plants, shrubs, trees and perennials.  Some of the top reasons we give people for mulching included:

  • It discourages the growth of weeds
  • Organic mulches decompose and feed your plants/trees beneficial nutrients
  • They retain moisture and allow it to be absorbed slowly over time
  • They act as a blanket, protecting roots from harsh cold and strong heat
  • It improves your soil’s fertility
  • How about it just makes your landscape look better?

Tchukki Anderson, BCMA, CTSP* and staff arborist with the Tree Care Industry Association says:

“Trees with mulched root zones are usually larger, healthier, develop faster and have higher rate of survival than plants surrounded by turf grass or bare dirt. Mulches retain soil moisture and nutrients and reduce erosion and soil compaction.”

While many people choose to lay mulch in the spring as they prep their gardens for the summer, Fall in fact is one of the most beneficial times of year to lay mulch. It will help nourish and hydrate your trees throughout the winter and will provide warmth to the soil and roots.

Good mulching

How Wide is Wide? A good mulch bed should extend out at least three feet from a tree’s trunk in all directions, though extending out to the dripline is preferred. This is where the fine, absorbing tree roots extend out into the soil, and mulch provides many health-related benefits for those roots. Keep all mulches several inches away from the base of the tree to avoid rot and diseases.

How Deep is Deep? The mulch bed depth should be maintained at 2 to 4 inches.

Go Ahead, Cover the Grass! If there is grass in the area that needs to be mulched, put a five-page layer of newspaper over the grass, get it wet, then add mulch on top (this will help keep the grass from growing up through the mulch).

Use the Right Mulch. For poor soils, use well-composted mulch to build up the nutrients. Soils that are healthy will do fine with a highly stable softwood bark (such as cypress bark), which doesn’t break down as easily.

Measure the pH content. Checking the pH content of the mulch ensures it is compatible with the tree and soil.

Bad mulching

• No Volcanoes, Please! The biggest no-no when mulching is to create a “mulch volcano” that is piled high around the base of the tree. This practice traps moisture around the tree trunk and root flare leading to decay and, eventually, structural failure.

SAY NO! TO MULCH VOLCANOES (4)

• Avoid Fine Mulch. Thick blankets of fine mulch can become matted and prevent the penetration of water and air.

• Don’t Let Mulch Sour. Low oxygen levels (from packed mulch) creates a toxic “sour” mulch – which may give off pungent odors. Even worse, the compounds produced during the souring process (methanol and acetic acid) can kill young plants.

• Don’t Keep Adding New Mulch on Top of the Old. While mulch does decompose, you do not want to accumulate excessive mulch year after year by adding fresh mulch every spring. If you want the look of fresh mulch, break up the old with a rake, and only add a layer of new on top if there is less than 4 inches in depth.
