How do raspberries grow? We have an east exposure. Do they send out runners and spread? Do they need supports?

Red Black. or Yellow? Red and Black raspberries may both be raspberries, but they behave differently. Red (and I believe Yellow) require large amounts of sun and tend to bush more. Black raspberries can thrive even in diffuse sun but tend to be less vigorous in their growth patterns. All raspberries, to the best of my knowledge, send runners. Remember that a runner will sap the parent plant, so once it is established, the runner should be severed to reduce the drain on the parent plant. Black raspberries (not sure about red or Yellow) thrive in soft, humus-rich acid soil. Raspberries are shallow rooted and are susceptible to certain diseases which, if infected, must be completely removed and either disposed of in the garbage or burned, but never put into the compost bin Black raspberries bear off of last year's canes, in late June/early July. Red and Yellow bear from the current year's canes from Aug to late October depending on the variety. Black raspberries at maturation physically resemble a smaller Blackberry, (they do not look furry like red or yellow) but they are (IMO) far superior in flavor and strength of flavor I live in a century old oak/nut forest (crowns are ~80-100 feet) with little or no direct sun in my yard. When I properly care for my gardens, I yield ~6-7 gallons of Black raspberries from ~ 20 plants over the 2-3 week harvest. I think red raspberries produce far large crops, although I can't say from experience since I can't grow them. Even if I did have sun, I'd still try to grow Black, since the flavor is, to me, exquisite. tart, and sweet
Darn it...I forgot to asnwer part two...ime, they need support if they are grown in a confined space...sort of espalie (spelling). it also makes picking easier...their thorns can be quite...discomforting...lol

From my experience, they tend to remain fairly shrub-like. Some support would probably be good--all the ones I've seen have either had small plant cages around them, or were against a fence. Be sure to prune it, though, or it may explode. Sun is good.

That's all my advice, you can find more online.
That last bit wasn't particularly helpful - this is an Answers section, after all!
I was answering! I answered what I knew, and provided a link to get more information. LMGTFY is my default search engine in the Answers section.

Raspberries do indeed send out runners and will, if they're happy, spread vigorously. You don't need supports - the canes arch nicely on their own. Your exposure requirements depend on region and latitude - raspberries like warm weather with full to dappled sunlight. My parents live on the Ohio river, and their eastern-exposure raspberry patch (planted in a bed up against the east side of a building) does great.

The hard part is keeping them trimmed into some sort of manageable stand or row to allow proper access without slicing your arms and legs up! Raspberries fruit on the previous season's growth, so you should thin out the canes that have previously fruited and trim new canes that are expanding outside your boundaries, but leave enough of the new growth to produce berries in the next season.

Good luck! If all goes well, you should try out my mom's recipe for fresh raspberry pie.
