A tale of 2 (or more) nursery cherry trees?


Yesterday, I was at Clarkdale Fruit Farm in Conway, MA to look at a new sweet cherry planting under a just-installed Haygrove Super Solo Tunnel.

What interested me, was the fact that there were some Radiance Pearl trees (all Gisela 5 rootstock) that were very nicely feathered, and with some branch bending, would be perfect for this hi-density cherry planting under a plastic tunnel: Pictured at left and click here for bigger picture. Notice the nicely feathered tree with small branches at just the right height. I told the grower to tie these down and he would have fruit on them next year, and this would be a very easy-to-manage central-leader sweet cherry. Immediate question: were these trees treated with Tiberon in the nursery? Or is this a variety effect? I understand these trees were from a small (ornamental) nursery in western Washington state, custom-grown for Summit Tree Sales.

Now, compare those trees to these trees: Picture and picture. This is what we more typically see in sweet cherry, rather big 'honkers' with few or no branches (whips) that are somewhat difficult to develop nice branching on for a central-leader tree. (Although they would be good for Spanish bush or KGB, as long as they have low-enough buds.) Bud removal is probably the most promising method of getting good branching on these whips or 'honkers.' (Video and video.)

It's amazing how different nursery trees can be from different sources -- a bit of a management challenge at times? JC

New website – tallspindleapple.com – focuses on the Tall-Spindle apple production system

The Tall-Spindle (TS) apple seems to have become the standard hi-density orchard production system in the Northeast. Promoted by Cornell’s Terence Robinson for several years now, the TS uses fully dwarfing rootstocks planted at 3-4 feet between trees and app. 12 feet between rows (~1,200 trees per acre) to achieve high early yields, high sustainable yields, reduced labor costs, and highest return on investment compared to apple orchards planted at lower or higher densities.

Although Robinson has been on the TS speaking circuit for several years now, and co-authored several publications on the TS apple production system, there is a new website – tallspindleapple.com (Fig. 1.)– with links to other websites, publications, and videos on how to do the TS.

Tallspindleapple.com is broken down into Publications, Presentations, and Video with links to the best TS resources on the web. For example, under Publications, there is a link to ‘The Tall-Spindle Apple Production System’ by T. Robinson in the New York Fruit Quarterly. Presentations include ‘Different Approaches to Tall-Spindle Establishment in Apple’ by R. Perry, and ‘The Tall-Spindle: critical steps to Suceess’ by J. Clements. Videos show ‘4 Rules for Pruning Tall Spindle Apple’ and ‘Pruning the Tall-Spindle from a Platform’ among others. New content and links will be added as they are published. Website visitors are encouraged to submit or identify new content for publication on tallspindleapple.com.

Tallspindleapple.com is the work of me and is hosted by the UMass Fruit Advisor (umassfruit.com). I bring 10 years of experience to tallspindleapple.com beginning with a 2001 visit to Italy where the Tall-Spindle apple is grown in quantity, visits to other progressive apple growing regions such in Europe and North America, studying Terence Robinson’s teaching, and my own experience growing Tall-Spindle apples at the UMass Cold Spring Orchard and cooperating apple growers throughout Massachusetts.

Wow, I am getting better on the posts. A few observations from my quick look-around:

Sunburn on apples is the worse I ever seen it. Undoubtedly from 2 weeks ago when several days approached 100 F. with full sun. (Is that like Washington weather?) I don't think this is going to go away by harvest. What to do? Well, if it is going to get hot and sunny again the only solution I know of is to apply Surround. I would do it only on my high-value apples like Honeycrisp and yellow varieties (maybe Gala?). Surround will also keep Japanese Beetles at bay. I am not sure if apples get more prone to sunburn as they ripen or not?

Dogwood borers in pheromone trap -- 19 in less than a week. Borers are mating and laying eggs on tree trunk/rootstocks with burr knots. Perpetual infestation by the borer larvae can eventually girdle and weaken or kill the tree. A trunk coarse spray of Lorsban targeting the above ground portion of the rootstock and lower trunk is indicated, particularly on rootstocks that have a tendency to form burr-knots (M.106, M.26, M.9).

Codling moth (CM) in dogwood borer pheromone trap. Hmm, what to think? I am concerned, although apple maggot sprays with an OP insecticide like Imidan should do the job in killing hatching eggs. I think, however, it is a matter of time before CM becomes more of a problem here in Massachusetts -- could this be the year? We may have to think about using newer chemistries such as Altacor, Delegate, and Turismo (among others) to control internal leps. I am confused -- are you? I would say there are no less than 15-20 chemical options, plus you could do mating disruption. (Too late for that this year.) Be sure to visit the NEWA website for real-time predictions on CM and other insect pests and diseases of apples.

Good luck. JC

A week? LOL! More like months, let's see April 30, now July 18. Cherries have all been picked. See here for my harvest results. Now we are picking early peaches, and likewise, see here for harvest results. All I can say is daily temperatures are averaging 5-10 degrees above normal, so I would think that, combined with the early bloom, are adding up to a very early peach season. Right now, easily 10-14 days ahead of 'average.' Based on the forecast, I think this is going to keep up -- I foresee Redhaven harvest commencing about July 31, which is a good 10-14 days ahead. We'll see.

Also of note, good attendance, 75+ at the Annual Summer Meeting of the Massachusetts Fruit Growers' Association, last Thursday, July, 15. Orchard tour of the UMass Cold Spring Orchard in Belchertown, followed by BBQ lunch catered by Outlook Farm, and then presentations by Peter Jentsch (Cornell's Hudson Valley Lab), Dan Cooley, and Duane Greene.
