Hmm... may I ask an offshoot question? It seems that everyone has specific beds for their berries. I planted 10 blueberrry bushes and 4 blackberry but I incorporated them into the landscaping... I.e. I didn't create specific beds for them (certainly not raised beds) although I did amend the soil well before planting.
Is there a reason everyone seems to have their berries in specific beds? I know some berries can tend to spread and I have my blackberries in an area where it will be easy to keep them in check, but I'm wondering if I did something wrong... I do have strawberries in their own little "island" surrounded by sidewalk... but nothing else is in a formal cordoned-off bed.
