Chris, you can do whatever you like! I have heard the leave old needles comments on this site, I guess you will have to show us how much better this makes trees. I haven't seen a need for it.
This is why you should pick a reacher and stick with them.
Thanks John. Interesting there's still not a total consensus on JBP needle management. Your candle cutting technique is in line with other teachers. Well, I did remove most if not all old needles last fall. This was before I heard about not removing them lol
So I guess I'll find out this summer how it goes. This is the one I'm going to the half bare root repot in a mos. or so.
<I also do preventative systemic insecticide (like an imidacloprid granule)>
All I could find in dosage is a 1/3cup for 150 sq. feet. How much do you use John? I just yesterday applied about 1/2 tsp/pot. Sl. more for the ones in wider/larger pots. I just took a guess, so I'd really appreciate some guidance on dosage. Thanks!
