Here's a photo of my Canby raspberry plant. The new stalks are only growing near the original stalk. My Fall Gold raspberry plant is also doing the same thing. Is this caused by my mulching? I would actually prefer the new stalks to grow away from the main stalk so that there's better airflow. A row of plants would be more aesthetically appealing also.
As a side question: are red raspberry's supposed to be yellow before they're ripe? My Fall Gold (yellow) is nearby and maybe the cross pollination caused my Canby to become yellow too. Can cross pollination even do that?
