I didn't realize that cukes were cucumbers but it makes sense! LOL According to the book, you can put 2 cucumber plants per square foot. That is what I have planned this year. I started seeds and put 2 seeds per section. I am going to separate mine and use them both.

Recall when transplanting you cukes, not to disturb the roots if possible. They don't like it like tomatoes do.

Good luck.

ewwww I guess that puts a damper on separating them. Would they be OK to just keep them together?

I would just plant all three of them just like they came. Unless you feel adventurous of course. If you do, let us know how it goes for you.

I would plant the cluster, then allow at least 12" of space on both sides for the roots to grow in. The roots of most of your veggies in the raised bed will grow sideways, after reaching the bottom of the box.
