I live in Pennsylvania and wanted to grow black and red raspberry plants any ideas?

They say to be very careful about mixing the colors of raspberries.  Some type of cross pollination?   I think you end up with speckled berries if you put red, yellow and black raspberries near each other.   And remember, thorns.   You need to find out about the types you have.  Some bear only on second year canes, some bear on new canes.

USEFUL FACTS

POLLINATION: Self-pollinating.

SIZE AT MATURITY: 4-6 ft.

HARDINESS: Hardy to at least -20° F, depending on variety. Everbearers are hardy in most of the nation if cut to the ground each fall and mulched.

SUN OR SHADE: Full sun.

SPACING: 20" between plants in rows 5 feet apart.

PROPAGATION: Cutting or digging up plants that come up from the roots outside of the established rows.

FRUITFUL LIFE: Replace every 10-15 years as they decline in productivity.

BEARING AGE: 1-2 years.

YIELD: 2 pounds per foot of row.

HOW TO GROW

SOIL REQUIREMENTS: Lots of organic matter and good drainage. They cannot take wet feet. If you have wet ground, plant them on a mound, 18" above the water table.

CULTURAL REQUIREMENTS: Plant with well rotted manure and fertilize the following spring with more manure. Provide adequate moisture during the growing season.

Pruning July bearers: Prune out second year canes in the fall after they are through fruiting. Don’t prune out new shoots.

Pruning "Everbearers": Summit and Golden Summit can bear on one and two year old wood. Prune or mow the canes each winter to get a free standing fall crop each year without using a trellis. Or trellis as you would with the July bearers and you will get a fall crop on the first year wood (primocanes) and also a crop the following summer before you remove the canes.

We feed them holytone same as our blueberries and in the fall cut canes down to about 8 inches.... don't worry they will grow back and you will have to pull some so you can do rows and get into them to pick.

Years ago, my husband and I got a few cuttings from my father to plant in our new yard.  It was the most effortless thing as I recall.  We put them in a place where they could just grow wild----and they did!  I don't remember having to do a thing to them to get them to grow and produce abundantly, except cut them back every now and then.  But in season, we would go out every morning and just pick and eat our fill of berries before heading off to work.   So, my only advice is put them off somewhere by themselves so they have lots of room.  Then....enjoy!

ETA: we were in northern New Jersey at the time, so similar in weather to PA, I think.
