root growth/how they do that

drip line  (feeding line/capillary transmission)

growing a tree evenly (above and below ground)

(NPK/compost may grow too much top too fast)

acid in roots dissolve minerals

trees then take them up into themselves

 trees hold (and therefore) tie up water

in re:  old growth  (barrels)

 how far do the roots grow from the tree?

what happens to the roots when the tree is cut down?

what do tree ROOTS do for the tree?

#1.  convert minerals into a useable form for growth  (breaking up rock)

#2.  take up and hold water

#3.  provide a stable place for the tree to grow

#4.  keep it in place through wind, snow, rain, dry

#5.  they may also create secretions that are amenable to their own (and non-competing) types of plants

(+/- catechins) allelopathy  U of Colorado (spotted knapweed)

Sassafras trees


ROOT KNOT  (CROWN in grass)

Conversion point where nutrients from photosynthesis meet nutrients from root conversion.

AIR:  crenelated area in bark, trees that grow in water take in air there.  circulation, breathing

EVERYTHING passes through this spot on the tree

pays to think of this as nostrils and mouth

we've all heard of trees being smothered by having this area buried too deeply

This is what you see (board)    this is what is really there

 TREE TRUNKS          

 why does the tree produce a log?

 what is going on, from the tree's perspective, as that log grows?

 stabilization of new growth

 faster/greater uptake (and circulation) of water, minerals (building blocks)

 there is also evidence that trees grow much taller/faster than usual when placed in competitive situations (not proof, just evidence) 

---elongated cells

-- release cutting...how it works

-- dangers of planting too close

-- disease transmission #1

-- shortage of water, nutrients, simple room to grow

 How close to plant trees?

-- Forestry department has worked out the ten x ten system.  NATIVE TREES!

-- most effective for HARVEST

-- good for quick growth as well  NATIVE TREES


#1.  Adds photosynthesis to general food system.

  --what does the TOP of a tree do for the tree?

#1.  the tree gets to spread its own seed farther by its own height

 -- photosynthesis (sunlight into feed)

 -- the top is where ALL new growth happens

-- all other growth:  roots and trunk are side issues to stabilize that top

-- each tree that reaches its greatest potential height produces an estimated million seeds. 

-- his is a "catch-as-catch-can" reproductive system  (seeds separate subject)


 BLM plants in style of chop/put tree in/stomp dirt around it

advantages legion:

-- smaller trees/quicker starts

-- trees root into hard soil sooner

-- gets huge amounts of work done fast

-- roots do grow from there

-- fast procedure gets trees out of air exposure quickly  (Air pruning)

what we are doing here is different

#1.  tree is non-native, EXOTIC  has to make the best it can of situation

#2.  tree is older than normal seedling transplant (greater root/top development) needs greater consideration.

#3.  by taking all dirt out and replacing it, dirt is loosened/compaction less

this encourages new root growth

#4.  adding peat moss/no nutritive qualities whatsoever/water-holding superb/ slows water evaporation over summer

adding rim to hole makes summer watering possible  (hole disappears over time)

sawdust around tree reduces or eliminates competing weeds/also helps slow evaporation

 WHERE to plant

-- Land Plan first  ("Planning changes everything"   ---Steve Renquist)

-- Suggest retaining DIVERSIFICATION

 -- plant 3 or 4 different species  (insurance against market lows)

-- (100-year drought cycle beginning)

 -- plant in strips, checkerboard, contours of land    whatever

 -- by planting in blocks or strips, you:

-- reduce potential spread of disease/parasites by INTERRUPTION

-- if a fire gets on your place, you have automatic fire-breaks

-- market variations mean you may have 1 type of log that will sell, when others will not

-- overall, even selling low, you will make out better in the long run.

-- more acres diversified, better such a plan will work

-- Start this type of program by making current and near-future harvests in smaller strips/blocks.  Replant in diverse patterns.  In the end, quicker results.
