It's been 3 years and no flowering, no berries, but thorny Titan seaberry is suckering all over the yard. Or, the suckers could be from the male or Star of Altai, but they're much less robust.
Any advice on organically killing the tree in a way that travels into all the suckers? I live on the central coast, and probably don't get enough sun for them to fruit anyway.
I would follow the suckers, wear gloves, and use a small shovel to make sure I was digging them up.

I grew seaberries through the 1990s. The suckering travelled about 15 feet, and it seemed that digging out the sprouts put an end to it. Males were much more vigorous than females. The blooms are early and very inconspicuous, are you sure you had no March-to-midApril flowers? The old German varieties offered by OGW did fine, the newer Russian and other varieties had no vigor. My Titan and Star of Altai barely grew for 3 years, all the others got huge.
Thank you, John and Larry. I pulled as many suckering roots as possible, potted Star of Altai and the male in one large pot (they weren't that vigorous) and chopped down the huge female Titan (which has sharp thorns), and poured vinegar on the stump and ends of any roots I couldn't reach. The roots were under other things I've planted, and didn't want to dig those up. Since there wasn't any sign of berries, I'm assuming it didn't bloom. I just don't have a big enough space for a suckering tree.
