New to tree health care?

I was recently asked by a young man, "What would you do if you were brand new to the industry? Where would you get started?" The answer is "Learn as much as possible about why trees go into decline, and ways to bring them back and make them healthy." Insects and diseases are very often secondary to other issues the tree has or had. Like working 70-80 hours a week - you can do that to yourself for a little while, but eventually your body / mind break down and you get sick. Trees are a lot like us in that respect. A little drought, no problem. Repeated months and years...big problems. Stress factors like trenching near the tree, parking or driving under the tree - even heavy foot traffic can cause a stress cycle to begin. Mowing right up to the base of the non-mulched mature tree, clipping the base with weed-eaters, etc. You can tell the tree is stressed by several clues. Does it seem thinner than other trees of the same species in the same area? Is the color off? Die-back in the canopy - flagging branches? The terminal bud scale scar will tell you a lot about the growth over the last 3-4 years. When did the growth go from 1-2' to 4-6 inches a year, or less? Be the detective for people and ask questions. What changed x years ago? Why is the tree in decline? This helps you figure out what might have happened to begin the decline, and how to correct the issues.

Horticultural problems are often the main issue. Is the tree in turf or mulched - is that correct, thick enough but not too thick - no volcano mounds! Turf is in competition with tree roots for water and nutrients, and they take their share first. You might notice there is no turf in the forest! Is the tree under irrigation? Know that should never hit the trunk! It can cause wet-wood diseases, sun-scald and other problems to set in! How frequently is it irrigated? It is better to water once or twice a week deeply than daily, or every other day - for trees, shrubs and turf need deeper roots. Daily watering creates roots that grow along just under the soil / grass line. These shallow roots are guaranteed to be damaged by excessive heat, traffic and will take in lawn herbicides more dramatically if they are frequently used. I would rather see an irrigation on for a solid hour, really deeply soaking the landscape and then off for several days. Make the roots search for the water in the soil depths, they are safer there.

So you learn to give advice to the homeowner, and it becomes you and them versus the problem. You are not selling them anything, you are helping them solve their problem. Once you have moved from across the table, to their side of the table figuratively, you can pitch the solution and the price. The magic number in business is 35%. Never spend more than 35% on products, the next 35% is labor - never exceed that and the rest is profit margin. It is best to figure gas / taxes etc into the last two items. The only thing that pays you to keep the doors open and lights on, is the profit margin. In 16 years of business, I rarely actually made more than 20%. Break-downs in machinery, bad weather, sick days for the salaried foremen and unexpected things always eat some of the margin. That's why it has to be kept at 30-35% as a goal!

So, back to the work you can do with little machinery and investment. A cordless drill and a rubber hammer - boom, you can inject trees with a two year fertilizer. Mauget and tree-tech make good fertilizers for hardwoods, pines and palm trees with no extra equipment to buy. This helps the chlorotic plants you see all the time to green up and gain back some vigor. Once you build a business doing more of this you can invest in tools from Arbor-jet, Rainbow Tree, or Arbor-systems to speed up your work and increase efficiency. They all work, and different systems have draw-backs and bonuses. They fix the immediate problems but do nothing for the soil, and in my opinion that's where most of the long-term 'fixes' can take place, to save the tree - long term, and make you money. The equipment needed, no matter which system you chose will pay for itself quickly. The fertilizers are long lasting and the result is usually quite dramatic. Take pictures!

A corded 1/2 inch drill, extension cord - heavy duty 100', a 24 inch by 3 inch auger -(we sell those) and you are in the vertical mulching business! Vertical mulching pictures are found on the web, essentially you are making swiss cheese of the soil under the tree and filling in those holes with a concoction of 'good stuff' to change the soil biota for the better. Soil,unless it is sandy, is like an old kitchen sponge. It gets wet, and wrung out thousands of times, and loses its porosity. It loses the 'air pockets' that allow water and nutrients to move freely. That is where the auger comes in, you drill every two feet in a grid that usually starts about three feet from the tree and extends about 20% beyond the drip-line. The holes need to be 4-14 inches deep. You can only drill so deeply depending on the compaction of the soil - this varies on every hole and soil type! Once all that fun is done you want to put some compost, or loose organic soil in each hole, a fitting fertilizer mixture and Vital blend Bio-char.

Compost can be bagged 'natures helper' - soil conditioner (lowes) , miracle grow soil etc. It just needs to be light and airy and organic. The fertilizer should be Tree-Nutri - 165 plus shipping - for a 50 inch caliper tree. (one ounce per hole) and 50 lbs of Vital blend Bio-char. (65.00 for 50 inch caliper's worth too) Then you kick in the soil on top of your good stuff and leave each 'hole' over-filled, as they will settle over time with water.

The tree-nutri is a 12-12-12 fert. plus micros like calcium, iron, manganese, magnesium, vitamin B-1, Mycorrhizae inoculants, and aqua-sorb. This expands into a 'jelly' that acts as a time-release for the fertilizer and helps the tree acces water in times of drought. The Vital blend Bio-char fixes nitrogen in the soil, is charged with fresh water humates, lasts 1500 years in the soil, and sets up 'condominiums' for beneficial bacteria and fungi the tree needs to thrive. A cubic yard of Bio-char holds up to 150 gallons of water without expanding due to it's surface area, which is about 7 square miles per cubic yard of material! It looks like coral under a microscope, and plants of all kinds thrive with its addition! It can even be used to increase corn and soy yields 35%, while cutting down on the fertilizer needs of the crops.

Get busy, do the good work of saving trees! There will always be a market for cutting, and removing trees, but will your back always be there for you?
 
Fantastic post and welcome! You already seem to be full of knowledge in areas that have recently sparked my interest. Just started my small business and preservation is my focus. Just bought my airspade and am ready to go. Thanks for this!
 
The air spade is a great tool! Now you just need some good stuff to put back into all those loosened holes, or trenches if you are doing 'spoke' trenching for trees! Check our site, it is brand new! treedoc.com
Best of luck on the new venture, where are you located by the way?
 
I definitely plan on getting some good ammendments as i sell the work as i do plan on doing radial trenching. Thanks for that and ill definitely check out your site. Funny yours is new too because I just published mine yesterday! Feel free to take a look and criticize as needed (edentreeeworks.com). Im in Boise, Idaho where the cowboys run wild and trees are last priority, but im trying to help change that

Glomalin is the gylcoprotein discovered by Sara Wright that seems to be the prime mover in the gluing of soils particles into aggregates that then are described as structure.

Pretty basic stuff from two decades ago.

Build Arbuscular Mycorrhizal fungi and reap the benefits. While compost is great AM (or Endo) are wholly obligate mutalists and therefore plants in symbiosis with fungi of the division Glomeromycota are the driving force for soil aggregation, not decomposers that like mulch.

Deep penetrating roots systems with AM can greatly benefit trees by increasing macropores and therefore positively affecting gas exchange and water infiltration. Crops such as deep-rooted carrots, parsnips, radish, comfrey etc. are easy and cheap ways to start rebuilding soil structure.
 
It means when one organism can't survive without the other. In this case, the mycorrhizal fungi living on/in/with the tree roots.

Thanks mr. Any recipes or resources you could share for building AM?

There seems to be little chance of building AM by the conventional, open a bottle and pour methodology. The single best way to get AM is to grow plants that have AM associations. Annuals are a great way under trees. Plant carrots and they should drive down to a depth at which soil density is such that they can penetrate (then you might need to sub-soil etc.). Let them die and the AM will help as will the organic matter and they can decay and offer vertical aeration as their largely water-filled mass decays.

In agriculture there is lots of emphasis on cover crops, things clover etc. but daikon radish or oil-seed radish are also very good. Sow twice per year (spring and fall) and watch the changes.

Commercial preparations (and aerated compost tea) do not seem to have beneficial effects that can be proved to be causal (as opposed to correlated). There are is so much that could be said about the problems with using AM as an income stream as opposed to using it as a chance to help trees, suffice to say that a sales pitch may be just that.
 
And another thing, to get organic matter into the soil you can rely on the old fashioned mixing in peat moss, or mulching, but ultimately you need roots living and dying along with all the other soil inhabitants to create a living soil (which is really old fashioned, just not anthropomorphic).

In some case you will need to break soil and amend to get some plants growing but remember weeds are weeds and they can be used to you benefit. Think of how lamb's quarters and red-root pig-weed drive roots down in a matter of weeks in even dry conditions.

The deep rooting annuals and perennials bit is great. Not far removed removed from no till ag with cover crops/green manure concepts.

On some tree bed expansion and installation jobs, I try to just kill existing turf without sod and topsoil removal and just mulch over it. A very thick thatch layer can soak up a lot of rain water at first but it eventually succumbs to decomp given time.

Can be a much less expensive method compared to breaking out the pneumatic gun and stirring and incorporating first then mulching. Depends on how your soil structure is to begin with. If compacted from construction and installation, air gun may be necessary.

Sell it as your lawn should be a "rug" not a "carpet" in the yard.

Yes, they are called tillage crops and for a good reason. They are an easily applied, soil building technique that is head and shoulders better than mechanical soil manipulation.
 
Where applicable Levi. The problem with tilling and air stirring is that it really speeds up OM decomp and many folks over-do the physical aspect and soil aggregates are destroyed.
 
Yep. Combo of weeds and mulch can make a huge difference. Compare the profile of that young bed to that in the lawn.
