Hugh,
You may be right, but not sure.
I found some info on adding boron to deficient soil below - sounds simple enough.
==
1 - Calculate the approximate square footage of the area where you want to add boron. Multiply the area's width by its length.
2 - Measure 1 tbsp. of powdered laundry borax for each 100 square feet. Mix each tablespoon of borax with 1 gallon of water in a watering can.
3 - Sprinkle the solution over the garden area. You probably won't need to add boron again for as long as three years, unless you test the soil and find a deficiency sooner, according to the Oregon State University Extension.

Problem is having too little or too much can be a problem for plants.
Should have soil test results before you do anything, and my standard soil test done on that area did not show boron content.
I am not sure if you read the details on how I put that bed together.
It is in the woods, on a north/east facing hillside. I broke up the ground in a 14' x 7' area and then raked the sides up to form a raised bed '14 x 4'.
I went to one of the best seng growing hollows I know of and got 6, 5gal buckets of the rock chip filled soil (30 gallons) and poured it on top of the bed and worked it in good to the first 3-5\" of soil. I also added organic material, composted peat (200 lbs), and also added gypsum, bonemeal and epson salt.
One thing that makes me doubt the boron issue is that of the 44 roots I put in, 42 came up last spring.
Only 5 of those had deformed leaves (the 5 I got from Billy).
The rest of the roots were local roots and they all had perfectly normal looking leaves.
If the soil was defficient in something and that caused the deformed leaves, then surly some of my local roots would have show the same symptoms, but they did not.
I think I am just going to wait and see how they do this year.
I just gave that bed a nice dose of gypsom, and that is about all I plan to do to it this year, except take care of the varmits that ate up my berries, and perhaps spray it a time or two with actinovate (organic fungicide).
When they start showign up here in a few more weeks, I will be posting pics - so we will all see how they turn out this year.
Thanks
