As for my 'Cascade berries', the theory is they are a cross between Loganberry and Rubus ursinus... and one of Loganberry's parents was also Rubus ursinus, so it makes sense that they share many traits.
Rubus ursinus *is* dioecious, but as long as the same cane is producing some actual berries as well as the husks, this doesn't seem like the whole answer...
I checked with the lady running this site http://www.garden-blessings.com/Pages/CascadeBlackberryPlants.aspx
She hasn't had this problem on any of her cascade berry canes; in fact, she says she gets 10 flats of berries from 8 mature plants, which is ludicrously better than ours have ever managed. So it certainly appears to me that this is a problem with my site or plants, rather than just the way things are for this cultivar...

I try to keep it to 6-8 canes every 10-12 feet of producing vines with room at the bottom wire for next year's growth.
It did say that Cascades are good in zones 7-9, and I wouldn't be surprised if some areas had close to Zone 10 temps late winter/early spring. Maritime tends to be cooler because of the fog, so that may be why really coastal Cascade berries did better.
I also mulch each bed with straw to keep the weeds down and the moisture from evaporating during the summer. During berry production I water after each picking, usually every three to five days. At other times during the spring and summer, I water once a week; more often if it has been extremely hot for a number of days.
How do you keep the canes to a minimum? Mine spread quite happily, and I'm currently using that power to have them out-compete the salmonberry, Himilayan blackberrry and Evergreen blackberry that I don't want. Would it be enough to just cut the extra trailing blackberry at ground level? Won't they just grow right back up?
Also, do you know how much the berries need to be watered, or indications that they aren't getting enough water? Thank you!

My berries are doing really well, and there was normal rainfall which gave them more of an irrigation than a soaking, which may have released nutrients that had been caught up in the drought-ridden soil. I had been watering, but the plants always respond better when Mother Nature does it. I am going to treat my berries as heavy feeders and heap the compost/weed mulch/rotted manure around them a couple times of year. Of course the new growth is next year's berries, so I'll have to wait a year to reap the benefits of last winter's rain.
Definitely get the canes out of there that had berries last year, even if they have leaves and flowers, they are sucking energy away from the canes that will produce.

In the areas where they are trellised, I've been removing the old canes, but it's really hard on the mounds of blackberries. I don't really have the time to spend scarring my arms digging out old bramble and ruining the newer growth while I do it. So, for now in these cases, I'll just take out the small canes and give them all as much duck bedding as possible.
Story like this gets better after being told a few times. Or maybe it's just a tiny ad:
