I've a vegetable patch which is near a long forsythia hedge. First two years were fine in terms of crop cultivation. But now it's really not productive. My parents say that the forsythia is taking up all the nutrients and that why my vegetables are not growing well. I put in a barrier between the fence and vegetable patch thick plastic borders not just the sheet) and then the weed barrier. Put in dirt and cow manure and planted veggies. Had good produce with beans tomato and cucumbers.
The year after I did not repeat these steps and my veggies did not do good. This year I'm planning to put brown bags and then fill it with dirt and cow manure. But I'm worried that because of forsythia all the hard work might go in vain!
What do you all think? Anyone has any advice that can put my thoughts at ease and go ahead with planting veggies? Do you think Forsynthia can damage my pathch?
