Hello all! I recently purchased 20 acres of
land in NE Washington with the plan to develop it over the next 5+ years and at some point after that retire to move there. The location is zone 6a(maybe 20 miles south of the 6a/5b zone), gets around 20" of rain per year and 35" of snow, and is at 1900' elevation. It is very very flat, maybe 5-10' of elevation change sloping from the NE down to the SW. The parcel is north/south oriented, about 600' east to west and about 1400' north to south. The property was being managed for timber production, with almost all the
trees being fir and some spruce, in various stages of growth. There are some older seed trees that I hope to use for building and a lot of younger trees that have been thinned/released here and there to promote growth. From my walk through it's in need of that again as new seeds have created some thick growth in spots. One of my biggest issues is my current location, I live about 1300 miles from this property. So my hope is to take 2 trips a year, drive up in the spring around last frost time and in the autumn before the snow starts flying, and perform what maintenance that I can with the goal of establishing a variety of other trees.
Phase 1: Hedging
As the title suggests, one of my first goals is to plant a living hedge around a reasonable amount of the land. Osage Orange (Maclura pomifera) would be the primary tree, planted from seed, in a single row 9" on center. As the whips grow from seed, in the autumn I would bend them over and weave each plant between as many others as it can reach. Then the next plant is woven above the previous, alternating the weave to lock them into place. The next year of growth from lateral buds would also be woven in during autumn, and each year the woven
fence gets taller. This is based on a method reported in "Hedges, Windbreaks,
Shelters, and Living Fences" by E.P.Powell, written in 1900. I believe that's where the phrase "hog tight, horse high, and bull strong" might have come from but I'm not sure.
Within 3-5 years the goal would be a hedge tall
enough to prevent the numerous
deer and elk in the area from hopping over to eat everything else planted inside. I would install a gate at either end of the hedge, something wide enough to allow a well drilling truck through, and I would need to lash junk poles to the gate to keep deer from hopping over at this point as well. Osage Orange is hardy to zone 4 and does fine in poor soil, which I expect this is if it was being farmed for timber. A forester will be doing a timber survey so I will find out how the soil is doing, and I could amend the soil as I go if it's really lacking certain nutrients. I also hope to mulch as much as possible around the hedge planting to keep grasses from invading and hindering the seeds. I was thinking of renting a chipper and tossing all the thinned trees which are mostly little things in there, and laying that out where possible. Due to the size of the
project it might also require delivering some mulch.
After a year or two of establishing, I would look at companion planting along the hedge to help it out, either
perennial nitrogen fixing plants and/or nutrient accumulators that I could chop and drop in the fall. Or perhaps just mulching to prevent any competition as the trees grow would be best? Once the hedge is tall enough to keep out wildlife, I would install the gates and plant fruit and nut trees inside to get them started a bit prior to retiring. I'm torn between broadcast sowing white clover and other ground covers to improve the soil throughout the site, as it may also attract deer as a feeding site- is that a valid concern? There is over 500 acres of timber land just across the private road so an endless supply of feeders would help themselves unless I have it all hedged/fenced off. But putting additional shrubs and ground covers along the tree hedge would be in the plan, once the new plants aren't competing so much with the hedge trees for
water and nutrients.
Phase 1.5: Coppice Wood
I'm looking at
black locust, red maple, hybrid poplar, hazel, and perhaps chestnut and beech as coppice options as they are all reported to grow and coppice well. I plan to build a
rocket mass heater and fuel it from the property, from coppiced wood and hedge pruning. I could also have different patches of coppice based on the use: if I find I'm using far less wood for heating then some coppice patches could go on a longer rotation to provide other materials. Outside of leaving the largest existing fir trees for building (looking at a wofati/Oehler style), I would expect to thin out plenty of room for new trees to grow. Of
course those new shoots are going to be vulnerable to foraging deer and as I'm looking to plant hundreds of each tree I'm not sure that there's a cost effective way to protect them all. So right now I'm thinking "spray and pray", and plant as many seeds as I have space and time, and hope that enough survive the first year to be a usable crop in 5-7 years. Then i would repeat the process each year, replanting from seed in all the spots that were eaten the year before. If I get lucky and a majority of trees are able to make it then there might be some older trees that can be kept as standards and eventually turned into new building materials as they thicken up. I could plant every 5-10 feet at first, say 2-3 seeds per spot, in the spring and thin to the best sprout in the fall or following spring. I would try to come up with a layout that places the locust in a grid of sorts that allows the other species to be nearby and hopefully benefit from the nitrogen fixing. But with different growth rates and needing to have a rotation that allows new shoots to get sun without competition from adjoining growth, I'm not sure how reasonable that would be. I consider coppice wood a lesser priority of "1.5" because the county has a program where residents can get up to 4 cords of
firewood for $20, which will more than cover my needs as a backup plan. I would not be surprised if deer ate every new tree they find not named douglas fir, although I'm hoping the thorns on the osage orange give them a fighting chance.
Phase 2: Food Bearing Plants
After the hedge has had time to grow large enough to limit deer pressure, I would look to plant some fruit trees and shrubs and additional nut trees inside the hedge for food production. As I doubt it would be reasonable for the hedge to surround all 20 acres, additional trees and shrubs for animal forage would be planted outside the hedge, and protected with fencing to let them get established. I would also focus on fruiting shrubs on the outside of the hedge, so animals will have plenty of options on their side of the hedge. I'll be looking at options that either store well via canning,
root cellar, or drying with a
solar dehydrator. I won't be expecting to live solely off food from the property any time soon, but as things develop I'll dip my feet into
food preservation and might one day add
chickens into the system. So starting off I would look at planting a variety of fruit trees that have varied harvest times, and build plant guilds around them. I will have a house plan designed by then too, so as fruit trees go in I will know where to keep clear.
Phase 3: Housing
Right now the plan is to get an owner-built exemption from the county and hopefully use the trees already on the property for material, cutting the logs the fall before, and letting them dry out before use as I build the next spring. I would be guessing the douglas fir are around 40 feet tall, maybe a little more, and were at 12-14" DBH. Based on
Mike Oehler's info that peeled log being 12" for beams and 10" for posts would work. Due to the nearly flat land, if I were to go with an Oehler/wofati/PAHS design and didn't want to have 200 yards of soil delivered for berming, it would require I excavate say 4 feet down, and use that excavated soil for the remaining wall height and green roof. A simple shed roof facing south would result in the
berm being 3' above grade on the north side and the south side would be 7-8' above grade depending on width and slope of the roof. Of course providing for drainage and keeping the posts protected from moisture and soil life will be key. I could see building a walipini that's attached to the house or nearby, with a
compost pile beyond that, and at the end where the slope drops a few feet perhaps mulch basins could be placed around a little grove of willow if gray water processing could be handled year round. The frost line is 30", but the hope would be that the gray water line would be out of any frozen soil if it traveled through the walpini and under the compost piles. I have no idea if that would work, especially if there was a very cold, cloudy week which prevented any
solar gain in the
greenhouse. Perhaps the first test
RMH could stay in the
greenhouse as insurance, and the second build would be inside? Then I could fire up the greenhouse model on the coldest days if freezing was a concern.
Any thoughts or concerns with the ideas above? The structural integrity of any housing is a given, and I will be looking at that for several years as I go out to the site to tend to trees. I'm sure my thoughts will evolve as I get a better understanding of what I have. Thanks in advance for any feedback!
