Hello I have 2 Blackberries in different areas of my yard. One is a SweetiePie blackberry. It produced over 700 berries last year from July-Sep. I was worried in late May of this year as I only had 1 cane total - a Floracane (full of flowers) [BLUE arrow in pic #1] but no new Primacanes. By May, my other thornless Blackberry (variety unknown) already had a single new primacane over 5’ tall. Then I was relieved in early June that finally 3 new Primacanes started growing [PINK arrows in pic #1] and are now 4-5' tall in 1 month. I was surprised though that today (July 4) I just noticed that 1 of the new primacanes has blooms. It is the one circled in BLUE in pic #2 and ORANGE arrow in pic #3 (pictured from behind). Notice that this cane is growing out of my one Floracane up 3-4 inches from the base. Would you say that since it was not growing from the base but instead from a few inches up on the 1 Floracane that it is actually just another branch on my one Floracane - and that is why it is flowering and will eventualy bear fruit this season unlike the other 2 Primacanes that will likely just grown and overwinter to bear fruit next year? I was assuming that new Blackberry Primacanes would be a little more distinct/apart from the base (you know how Raspberry new growth is often several inches away (through rhizomes/roots) from the base. Do you think 1-2 Primacanes is normal for a 3-4 year old blackberry? Still learning .... Thanks for your advice.
