Dear Mr. Reuben Hofshi,

In your article "High-Density Avocado Planting - An Argument for Replanting Trees" you state in Table 3 that the production yield per tree in the 5th, 6th and 8th year is 80lbs/tree. I have viewed other article relating to Ventura County showing much smaller yields of 19, 39, 67 and 67 lbs/tree, respectively.

Have you experienced an 80lbs/tree yield in your high density Hass orchard.

I reside in Somis California in Ventura County.

Sincerely,

Will

We don't have Hass old enough to varify these numbers which were projections. Our 10X10 Hass on Duke 7 bloomed at 14 months from planting and produced 8,000 lbs per acre. We have several plantings of Hass that will begin to produce this year and the set looks very promising. This year in Chile 2500 acres have been planted with this density and we should be able to have more production data soon.The most we were able to Reeds trees to produce has been 76,000 lbs per acre. We were not able to repeat this level of production since. I believe that if trees are well maintained tree replacement will not nbe needed for at least 12 years.

Dear Mr. Hofshi,

Thank you for your reply.

High density planting creates a high startup cost per acre. My current plans are to plant 4 acres the 1st year and then an additional 4 acres every year thereafter until I reach 20 acres. Due to the high cost of planting, I plan to grow and graft my own Hass onto Duke 7.

Is Duke 7 in the public domain? Where can I get Duke 7 to grow my own rootstock?

Great idea to stagger the planting and to make your own rootstocks. It is a simple operation if you understand the concept and the process. Both Reed seeds and large Zutano seeds are very good nurse seeds. There are several papers on this web site talking about cloning. Maybe the people at Topa Topa nursery can show you how to produce clonals.
Matan Hadari, an Israeli student just wrote a thesis at the Technion in Israel comparing different planting geometries. From real measurements and simulated ones his model clearly show that high density planting are much more efficient light grazers than any other planting type and thus have the potential for high production.

Hi Reuben,
