Hi all!
My partner and I are buying 10 acres on the Olympic Peninsula of WA. Part of this is an
apple orchard that's about 20 years old and includes 269 varieties of apples! Totals about 300
trees. Needless to say we are beyond excited!
Now, the trees are densely planted mostly dwarfing rootstocks and trellised with metal poles along each trunk and a single wire along the top (at about 7 feet - the height of the trees). The pruning is strange - kind of espalier type, S shaped. Grass is in the rows and aisle.
To begin with, and because it's in a farm tax exemption we are going to continue selling them as hard cider apples to a
local producer.
Anyway, a couple things we have to figure out: for one thing, many of the trees are unfortunately girdled by string (tied to the
trellis) and plastic tape that wasn't removed in time (the seller is 90 and hasn't been able to keep up). There's peeled bark along these areas (especially along the tape) and along pressure spots where the trees press against the metal posts.. It's turned black there and often the distal portions are dying back. We are removing the tape and string where it hasn't been swallowed by the tree. But
should we paint something on to these areas to help protect the trees?
Also, there is possible Fireblight (not sure) on a few rows with dying branches (no dead leaves still attached tho) and peeling bark. On the worse trees (only a few) there is bark peeling down the trunk even. What's a good way to tell if this is indeed Fireblight and if so what should be do about it? A friend recommended Michael Phillips "Holistic Orchard" which we will try to follow eventually but for now we are where we are..
Also the trellis itself seems to be a bad idea- two rows have collapsed completely with domino effect and as I mentioned posts are pressing into many trees. Could we remove this completely or ween the trees off it?
Finally (well more problems/solutions to be discovered I'm sure) there is the
irrigation issue. We have a marine climate, zone 8b and pretty sure Csb on Koppen scale. It's in a Rainshadow behind the Olympic Mountains so near desert prairie (yes in the PNW) is bordering us to the west and an inch of rain/mile traveled west is the rule of thumb. We get around 25"/year but almost all of that is in the winter. Summer will be really dry and irrigation of even established trees is common here.. W
Fortunately the soil type holds more water than most in the area as a silt loam.. Water sources are two
wells (but not legal to use on the orchard), a
pond that even though there's been a lot of rain is only half full and it's fairly small, and the best source is river water off of a gravity fed network (dates back well over 100 years in this area and consists of a series of open ditches routed off the Dungeness river in the foothills of the mountains and predates water regulations but now has an instream flow threshold for the salmon.. Getting off track - the irrigation ditch runs along the east border of the peppery and flows from April 15 to Sept 15.. Flow is very variable and PSI ranges from very low to 60 psi in some areas - don't know how much we have yet..) so the water is there but the irrigation ditch is notorious for sediment and plugs pumps. I'd like to run drip tape to the orchard but hard to say yet it there's
enough pressure/clean enough.. In the past he filled the
pond with the water and pumped from there but that's quasi legal. Many people pump right from the ditch piping itself but to sprinklers. Anyway I'm not sure which route to go or where to begin - any suggestions?
I can take pictures next time I get out there (we move in in about two weeks.
