Apple Wassailing and Pruning Work Party February 4th

As I walked by the orchard today, I came across the winter quiet of the orchard and this sign about our upcoming Apple Wassailing, featuring Sound & Fury Morris and Sword singing and dancing, a tree blessing, and a Pruning Work Party on Saturday, February 4th. The work party starts at 11:00AM, and the wassailing will begin around 11:30AM. We will be serving hot cider, cocoa and other treats. Come join us!

Art in the orchard?

Not sure what this piece depicts, but art is definitely in the eye of the beholder. This year’s weather has produced a bounty of fruit. Most varieties are not yet ripe. If you’re in the orchard, it would be a great help if you could pick up a few apples and put them in the nearby garbage can. We’ll have a concerted effort for orchard cleanup on Saturday, 8/6, from 10AM to 2PM, as well as some summer pruning.

Our King is doing well

This King is right near the trail, and the beneficiary of an art project from several years ago that put up a mason bee house. For more information about the apples in the orchard, follow this link.IMG_5260

Looks like a nice Red Bietigheimer apple growing on its tree in the orchard. High enough up to avoid someone casually picking it.

Tree Replacement and Solarization Project

Tree Removal Plan for Piper’s Orchard

The historic Piper’s Orchard has over 70 trees.  Some of these trees were planted in the 19th century by Andrew and Minnie Piper and represent heritage apple and pear trees that are still thriving even after 120 years. Many of the other trees in the orchard were planted by volunteers only 30 years ago, are not of historic importance and are badly diseased. These newer trees are disease-prone and are not contributing to the well-being of the orchard.

Specifically:

  • The tree on the grid marked H2 is blighted by a condition that recognized state expert Dr. Robert Norton says will guarantee the tree will be stunted forever.
  • The trees in grid spaces C4 and D6 are blighted with crippling cases of anthracnose.
  • A copy of the orchard planting grid can be found here:https://pipersorchard.files.wordpress.com/2010/03/piper-orchard-map.pdf

Removing the orchard of these trees will:

  • Improve the appearance of the orchard
  • Reduce the anthracnose disease spores
  • Make room for new and better transplants in these spaces in the future.

The decision to remove trees from Piper’s Orchard has been based on discussions between the volunteers who have been maintaining this orchard since 1983, members of the Seattle Tree Fruit Society and professional horticulturists. All concur that this would be a good decision to maintain the health and beauty of the orchard.

Although there are other existing trees that could be removed, the ones mentioned above are of particular decay disease.

After these trees are removed we would like to replace them with trees representative of the 19th century. In addition, there are spaces where trees died many years ago and we would like to continue planting replacements in Grid spaces B1, B2, G1, G6, H5 and H6.

In order to provide soil that will help new trees survive we plan to test a solarization plan.

Soil Solarization and Historic Tree Replacement at Piper’s Orchard

Background

A primary objective of historic orchard management is the replacement of vacant, dead or diseased trees with new trees of a rootstock and variety suitable to the character of the original planting.  Unfortunately, new trees planted in an old orchard setting often suffer from Specific Apple Replant Disease (SARD), or “sick soil syndrome”.  The causes of SARD are legion.  Often a combination of viral, bacterial, metazoan, fugal and animal pests contribute to the presence of SARD.  Despite its name, SARD can affect not only Pome fruit trees, but species of Prunus and Citrus as well.

Soil solarization is chemical free, pesticide free, salmon friendly, and an organic method of controlling pests and soil borne plant pathogens (including fungi, bacteria, nematodes, insects and weeds) by mulching the soil and covering it with transparent plastic.  This method is very low tech and low effort.  It utilizes the greenhouse effect to disinfect soil via prolonged and repeated thermal treatments.

Method

  • The area to be solarized is staked out.
  • The sod is broken either manually or by a tilling machine.  Organic material is removed and composted.
  • The soil is irrigated
  • Two layers of clear plastic are spread over the tilled soil.  The edges are secured by stakes, rocks, heaped dirt or a combination or the above.
  • The soil remains covered through the late spring, summer and fall.  In the winter, new fruit trees are planted in the sterilized soil.

Proposed Application in Piper’s Orchard

  • Don Ricks will identify diseased trees, as well as vacant positions in the original orchard grid.
  • Based on Don’s report, the Piper’s Steering Committee will reach a consensus on the area to be solarized.
  • Solarization will begin in the spring of 2016
  • Adam Wargacki will provide rootstocks to be planted in appropriate positions in the late winter, 2017. Adam and other Friends of Piper’s will provide grafting services.  Two or more rootstocks may be planted at each position to account for inevitable loss of young trees by attrition (mishap, disease, animal predation etc.).  Eventually the single healthiest tree will be left to occupy each position in the grid.
  • Bob Baines will oversee varietal and rootstock selection, in order to preserve the integrity of the historic orchard landscape.
