Dear Philly Orchardists,
September is always an exciting month for orchard harvests, with many of our favorite fruits ripening including figs, paw paws, Asian pears, and more! 

Please check out our new POP Monthly Orchard Task List for recommended maintenance activities to complete this month (the Sept/Oct list is also attached below). 

Here is some more detail on some of the key tasks for September: 

Orchard Watering

New plantings (from this spring or last fall) should be watered thoroughly once per week until they drop leaves and go dormant.  In most years in our wet climate, established orchard plantings don't require much in the way of supplemental watering except in the case of extended drought conditions.  


Summer/Fall Weeding


Although weed growth will soon slow down with the onset of cooler weather and shorter days, many weeds are still growing rapidly and setting seed.  Weeding at least once a month is advisable for orchards and food forests throughout the summer and early fall!  POP's weed identification guide is available for sale on our website and we always have free copies to distribute to community orchard partners. Check out POP’s guide to Ramial Wood Chips and Weeding in Place.  


Emergency Pruning


As summer comes to an end, it becomes increasingly important to limit pruning to emergency pruning only.  Fall pruning can result in new growth that doesn't have time to harden off before winter temperatures hit.  


Keep an eye out for any diseased, damaged, or dead wood that should be pruned away no matter the season.

Fall pruning should be limited to emergency removal of dead, damaged, and diseased wood.  In particular, prune out diseases like Black Knot (pictured above), cankers, and fire blight that can continue to spread and cause further damage if not removed.    

Remember: use sharp, rust-free hand tools and sanitize between every cut for disease prone trees during the growing season. For easy disinfecting, we recommend carrying a spray bottle with you of rubbing (isopropyl 70%) alcohol or a bleach solution (1 part bleach: 10 parts water) to wipe down tools.  


Pest and Disease Monitoring & Identification


Many orchard pests and diseases are active throughout the summer months and into the fall.  It is important to continue weekly monitoring of your plants to identify and manage challenges.  Some of the most common insect pests to contend with in September include:

Keep an eye out for peach tree borer damage at the base of all stone fruit trees from summer through fall!  Unlike most insect pests, borers can actually rapidly kill an established tree if left unchecked.  Use a flexible wire to kill any active larvae and read more about preventative measures here: https://www.phillyorchards.org/2015/07/13/peach-apple-and-other-fruit-tree-borers/

Observe your orchard regularly throughout the year for pest and disease problems, identify and respond appropriately.  We've begun distributing physical copies to community partners, but in the meantime you can check out our POP's Scouting Guides for pest and disease management available for download on POP's website: 


These guides are intended to help properly identify the insect pests and diseases that affect the following common fruit trees: 


The guides include lots of photos and a description of how to identify the particular pest or disease and the damage caused by it.  Proper identification is essential to treating these problems, as each has its own unique options for management!  Once you have identified a pest or disease, you can then consult our website for management recommendations by using our search function: 


Read our recent POP TIPS email with specific summer tasks for Oriental Fruit MothBrown Rot, and Spotted Lanternfly management. 


Remove Damaged and Dropped Fruit

For fall fruits, it is advisable to continue to monitor your developing crops for insect and disease damage and remove the affected fruit.  Similarly, it is best to gather any fallen fruit to avoid the further spread of pest and disease challenges.  All fruit should be disposed of by adding to a hot compost system, feeding to poultry, or bagging up to remove from the site.

September Harvests!

Look out for ripening pears, paw paws, figs, Asian pears, apples, grapes, everbearing raspberries, everbearing strawberries, almonds, hazelnuts, cornelian cherries, jujubes, elderberries, chokeberries, maypops, rose hips, perennial herbs and greens, and more!  Record your harvests using our handy POP Harvest Tracking Sheet.  


Enjoy the September harvests and cooler weather!

Dear Philly Orchardists,
Pawpaws are ripening early this year, with many sites reporting harvests last week- check your trees if you haven't already!  September is always an exciting month for orchard harvests, with many of our favorite fruits ripening including figs, paw paws, Asian pears, almonds and more.  Please also consider joining POP staff, partners, volunteers, and supporters at our upcoming Orchard Celebration (virtual on 9/23 and at The Woodlands on 9/25).
