I wouldn't plant raspberries near strawberry bed. They grow most vigorously at time of strawberry harvesting. If you pull out at this time, you, first, disturb much more shallow strawberry roots in the hot weather and, second, disturbing the soil can start gray mold spreading on you berries. Only choice you have in this case not to pull, but just cut the green parts. It will not stop them from growing, but will let sun to get to your strawberries. Raspberries like reach soil. If you have well cultivated row and original soil outside of it, they will not spread much assuming you do proper pruning . But as soon as there are some better or equal places to grow - they will start moving. I have shoots here and there as far as 5 feet from original planting side.

Hi Weeper- I'd stay away from "Fall Gold" if you could. (I've been posting a lot of the same advice lately, so hopefully the other readers will forgive me). There are only 3 yellow varieties that are ever talked about: 'Anne' which is arguably the best tasting variety of raspberry that is out there... very large berries, but not a very productive plant. 'Kiwi Gold' which has a unique and good flavor, and is extremely vigorous. And 'Fall Gold' which doesn't have any of the positive attributes of the other two. If you look at my 'My Page', you'll see that I'm growing Anne and Kiwi Gold, but I have never grown 'Fall Gold' simply because the posts here on this forum are always poor. My only hesitation with recommending Anne and KG is your zone 2b/3a. I don't have any experience with what will and won't grow up there, but given a choice, I'd take Anne or KG over FG any day. Yep, I do have a Regents serviceberry (Saskatoon), but for some reason, the berries always turn black and shrivel up. O'well. Good luck, -Glenn

Ha! I've been called out! :-) Fanatic is as good of word as any. Thanks Olpea! I was actually waiting to see if someone could offer better advice here than I could. But, since there's nobody yet... As for thornless raspberries... I grow Joan J which is indeed thornless. It is about the only one which I know of which is truly so. Some others here (such as the well respected Fruitgirl for one) had Âdissed Joan J in the flavor department. At the time, I couldnÂt see it because mine tasted fine. But, this year was different. During the beginning of the year, they tasted pretty darn lousy but then they seemed to get better as the year went on. IÂm wondering if it had something to do with the record setting rains we had this spring and early summer here in RI. Perhaps Joan JÂs flavor is more subject to too much rain? IÂm not sure. But, as Olpea points out, the thorns of most of my red and yellow raspberries really arenÂt that bad. Black raspberry thorns are a bit vicious. And thorny blackberries are definitely quite vicious (which is why I really prefer thornless blackberries). But, because the reds/yellow thorns arenÂt bad at all, I wouldnÂt limit yourself to the very few thornless varieties. The part I didnÂt know how to answer in the best technical manner was the "suckering out from the crown". IÂm drawing a blank on what this trait is called, but it must have one. (IÂm sure IÂll slap myself when someone reminds me). Anyway, my Jewel black raspberries have this quality. If I plant one plant years later, there will still be a local grouping of 2-5 canes within a 1" diameter. (But, they are very thorny, so perhaps this isnÂt a good candidate for you) In my case, the same red/yellow raspberry would have exploded to fill any bed within 3 years. My Chester, Triple Crown, and Doyle blackberries and I believe my hybrid Wyeberry also have this quality youÂre looking for. So based on all of this might you prefer some thornless blackberries instead? YouÂll need to wait about 15 months after you plant them to start harvesting your berries, and youÂll need to provide them some strong support (If you click on my "My Page", you can see what I mean). Stay away from the thornless blackberries with native-American sounding names because I believe all of them do sucker out from the crown. Where in 6b are you located exactly? Get back to us on which way your leaning, and we can probably help steer you further. Hope this helps, -Glenn

Roadside Daylily- Hemerocallis fulva 'Europa' (aka "ditch lily") is another one that will spread and take over quickly. I have some 10yo patches that are into the roses and other perennials near them. I dug out 2 clumps this fall and it was quite a job to separate them from the weeds & other plants. Plus, I had a gardening house guest a few years ago who planted some of the spreaders from these next to a red dl. They grew together and both quit blooming from being crowded. Now I have no idea which is the red. I've seen some newer cultivars that have these species types in their near lineage and the hybridizers state the new ones are also voracious spreaders.
