Can you have tomatoes planted next to roses?? I'm wondering if that may be the reason why my tomatoes are not doing so well this year...( and last year too since some roses were planted in there). Thanks.
I cannot think of a reason one would affect the other, as long as they're not shading each other out. Tomatoes are very weather dependent, and vary quite a lot year to year based on how much heat and moisture they experience. That seems a more likely explanation.
