I need advice
I plan to grow roses in the greenhouse and I need basic numbers and calculations like how many roses I can grow on 50 square meters, spaces between plants, ammounts of fertilizer, etc. Any links?
You might want to look at these sites.
If you post on Garden Web be sure and change the title of your post on each forum or their computer will think you are spamming and block you.
Your profile doesn't say where you are from, but I'm guessing it's not the US as you are asking in meters. Do look at their other rose sites just in case that will be helpful.
Wow - great resources! My aunt has a greenhouse and wants to grow roses, I'll get some of that info for her and thank you very much!
I'm so glad you found the sites helpful. I've got quite a few on roses, so let me know if your aunt needs more.
