It’s May! The Busiest Month at the Orchard

May 24, 2017

saran-wrap-wp_20170524_003Don’t blink. You might miss something. Everything is growing and gardens are glowing. Welcome new gardeners Mitch, Michael and Stuart.

Michael and Stuart got an early start by protecting some plants with saran wrap.food-bank-no-2-sm-wp_20170523_007

Sue has a second food bank bed, and hoop-contents-sm-wp_20170523_004not surprising, it looks professional. We took four pounds of greens from her hoop to the food bank today.

The word spread like fire around town last week that someone caught a codling moth in a trap. We raced to get the apples and pears protected by installing nylon ‘footies’ plus netting.

ladybugs-sm-wp_20170517_007While adding the footies to the apples we could see that the bugs are busier than we are. Here are two ladybugs on the Fuji. Well … they can’t both be ladies. And spiders-sm-wp_20170523_008 newly hatched spiders in the Liberty, all scrambling out, ready to explore. Ladybugs and spiders are two of the best beneficial insects for the orchard.

Kate and Elley carved out a new garden bed in a couple of hours. A day later, Sue attacked and created a nice looking nest for kate-w-pepper-bed-auto-correct-sm-wp_20170521_001the hot peppers. The weed barrier paper is OMRI certified organic and biodegradable. sues-peppers-sm-wp_20170523_002What a nice looking nest for the pepper plants.

Since we can’t control ourselves at plant sales there are a few new plants in the north end. Come and find the new Salvia Hot Lips (Slavia Microphylla) and the Sapphire Blue Sea Holly (Erngium). Ciscoe Morris himself told us these two plants would give us the August flowers that the pollinators need.

All of this activity in the space of about a week! We hope the show slows down a bit in June.

Winter Moth on Attack

May 3, 2017

On April 21, I noticed a rolled leaf on the Twinberry at our house. I shuffled over to our apple tree. best-of-back-wp_20170427_001Hmm. More rolled leaves. I jogged up to the orchard and every fruit tree that had leafed out showed this same leaf damage. What was this small green larvae with a stripe down it’s back?

The Honeycrisp got hit hard since the pest arrived just as the tree was leafing out. The fruit gods had mercy on the William’s Pride and Liberty because they were ahead of the curve at full blossom stage.

best-of-tail-wp_20170427_008The larvae had certain characteristics: an udder like organ toward the back end and also a two-barrel exhaust at the tail.

You can’t have a good management strategy without knowing which critter you have. So, I looked at pages and pages of moth larvae on the internet. The closest I could come was the light brown apple moth. Lucky for us in Washington, it was not that. The larvae of the light brown apple moth have an anal fan of forklets.

Chris Looney, from WSDA came to the rescue to identify the pest as the winter moth (Operophtera brumata). (It’s within the group called loopers or inch worms.) It is common in our area and is not a leafroller, even though it rolls leaves. Its behavior is described more as sticking one leaf to another with its silk but, in fact, I can tell you it also rolls the leaves to make a nice hiding spot.

The udder looking appendage is actually called abdominal prolegs (versus the true legs up front) and the dual exhaust is simply the anal proleg.

“Damage to blueberry and apple crops is especially severe as the reproductive parts responsible for fruit can be destroyed before buds open fully.” (https://ag.umass.edu/landscape/fact-sheets/winter-moth-identification-management)

You can say that again. Just as the flower buds peek out and huddle together between tight cluster and pink stage, the caterpillar attacks.

Tree trunks can be checked for the tiny orange eggs during the winter. Eggs hatch when temperatures average around 55 degrees. Winter moth larvae are active for only about three or four weeks. After they have had their fill, they will dangle down to the ground on silk and burrow into the top layer of soil, where they will become dormant pupae until emerging as adult moths in late fall for their nighttime mating. The flightless females will climb up trees lay eggs on the tree bark, and die. Then next April those eggs will hatch and the cycle begins again.

For organic management, we will try a dormant oil spray to focus on destroying the eggs this coming winter. This might only be partially satisfying since eggs are deposited virtually everywhere on trees and shrubs and new caterpillars can quickly migrate from untreated areas to the oil-treated plants by ballooning via their silken threads.

When applying oil sprays, temperatures should be above 45°F. Avoid spraying when temperatures may dip below freezing for 24-48 hours after application. (Temperatures below this threshold increase the risk of causing injury to the plant phytotoxicity – https://tinyurl.com/laqhckl). Certain weather conditions, such as when it is cool and cloudy, can also delay drying time and enhance the potential for injury.

Look-alikes: Blueberry sawfly (does not have pale stripes along body) Cankerworms (has two pair of prolegs, one shorted than the other), Bruce spanworm (found in the Northeast U.S.)

If anyone is interested, we are paying a bounty – 10 cents per larvae! Tell your friends about this lucrative offer.

Off With Its Head!

March 3, 2017

The bold Honeycrisp is too tall! “Bring down the height and the apples are within reach, plus the ladder can stay in the shed.” We all nod with approval. Ingela is convincing.c-wp_hc-before-20170218_006c-hc-after-wp_20170218_007

Eight of us gathered in February to enjoy Ingela’s annual pruning class. She walked around each tree, backed up, pondered, then attacked. Swiftly and gracefully, she snipped, sawed, and talked us through the process.

 

 

 

Ingela will train the new Harrow Delight pear to a central leader so we have different training styles in the orchard. She carefully ties down the new scaffold branches, denying their desired upright position.sm-pear-before-wp_20170218_001sm-pear-after-wp_20170218_004

 

 

 

 

Tips from Ingela for your bypass pruners:

  • * For an effective tool – Always keep a sharpening tool for your   pruners on your belt.
  • * For sanitation – Have a bottle of 50% water 50% alcohol in your tool belt.
  • * For clean cuts – Adjust your pruners so there is minimal play between the blades.
  • * Annual cleaning – Note the bolt that locks the pruning blades. When you take the tool apart for an annual cleaning, add a little lithium grease.

What a pleasure to watch an excellent tradesperson. Ingela’s ease with trees comes from years of pruning plus a complete knowledge of how fruit trees grow.

Join us some time in April when we graft a Rescue scion onto the new Harrow Delight pear tree. We should get better pollination from this strategy, but it’s just as much an excuse to provide a fun educational experience.
