Hmmm...
I need 65 trees to replace the ones that have died in my plantation (a loss rate of about 4% which is OK), and I had 10 left over tubes for planting new ones. That's a total of 75 trees, I also owed my wife a tree for our anniversary.
However, partly because of minimum order quantities and partly because of lack of stock elsewhere, I've now ordered today:
50 x sweet chestnut, castanea sativa
25 x wild pear, pyrus communis
10 x common dogwood, cornus sanguinea
25 x black locust, robinia pseudoacacia
25 x black maul, salix triandra
1 x black mulberry, morus nigra (anniversary present)
1 x almond, prunus dulcis (present for me!)
That's 137... now I have to decide which get the tubes and which only get spirals (of which I have hundreds!)
