I have ordered 4 Blackthorn Bushes (Prunus spinosa) to plant in my yard here in Baton Rouge, La. The lady from whom I bought the bushes advised me they would do fine in my clay filled, alkaline soil with no amendments necessary. She did advise me to plant them in a spot that would give them some protection from the afternoon sun - it can get very hot and humid here in summer.
My questions for y'all are two. First, where should I plant them to best protect them from the afternoon sun? Compass-wise and in relation to shade from larger trees/bushes? The noon sun is presumably OK, I'm guessing. I think what was meant was the hottest part of the day - 3-4pm.
My second question is how to get them to grow as straight a main trunk as possible? My intention is to grow them to maturity and then harvest them to make canes for me and my brother and brothers-in-law. Naturally, I'd need a straight trunk. Any idea on how to achieve this?
Thank You All, Very Much,
