Don't plant your Jewel between your Heritage, bad idea. Either plant at the other end of your garden space or in planter. I'm cheap so I would use a 5 gal pail and drill a bunch of holes in the bottom for drainage. Then fill the bottom third with coarse sand and then a mixture of sand and heavy soil. Brambles don't like their feet to sit in water. Note: Black Raspberry plants can tolerate more shade than the reds. You should also read up on how to prune black raspberries as it is different than reds.

I ended up putting my black and red raspberries next to each other. It has been two years now and I have not seen any disease problems. My black raspberries fruit before the reds and overlap a bit with the first crop on my reds but my reds are everbearing and I prune them to get both crops. Rabbits love raspberry plants and even the nasty thorns on the black raspberries don't stop them. If you have summer bearing reds then you'll need to protect the canes over the winter or you won't get berries since they fruit on second year canes. You'll need to protect the black raspberries too since they also fruit on second year canes. Both types of raspberries spread easily, so I would leave a space between them and the veggie garden. Reds spread underground through runners and end up taking over anything planted near them. Blacks are a bit more manageable as they spread by tip rooting so you only have to keep the tips of the canes from touching the ground if you don't want more plants. You can do this through a combination of trellising and pruning.

Yeah, my first year same thing happened. The black took a few extra weeks (3 or 4), It's 2nd year it's come out pretty close to the other caneberries.

My jewel black raspberries have finished up blooming, the picture above is essentially the only blooms left. This is my first fruiting year with black raspberries (jewel and mac black) and it is a "baby" crop but enough to get a good taste. I have a lot of berry plants having their first fruiting season (2nd year) and it is really interesting to see how much larger and more robust the primocanes are this year than last year, especially on my raspberries and trailing blackberries. Fruit production on those the new primocanes next year could be 2-3x as much. One other thing Drew51, you'd better have a decent size area for that siskiyou blackberry. I spent some time today tying up the 6ft canes (each 2nd yr siskiyou has 6 canes at 5-6ft) and it is only the beginning of June. They are growing at the same rate as my marions, which produced canes last year at my house up to 20ft. :-)
