This is the first year I'm taking care of a vegetable patch. It's a total of ~6m² which I have divided up into smaller areas. I have sown some seeds two weeks ago which are beginning to sprout. However, in most patches there are two types of plants coming up. I think I have identified which is the weed, but wanted to check with you to be absolutely sure, especially because seedlings can often look so different from the final plant. In the pictures below I have circled what I think are weeds, in a patch with dill and spring onion.
The reasons why I think these are the weeds:
- They appear in every patch, while there is more variety in the other type of plant found in each patch.
- They don't look like what I would expect from dill and spring onions.
The reasons why I'm not sure:
- I also have patches with spinach, leaf celery, arugula, and Swiss chard. There it is much more difficult to distinguish two types. This may be because the vegetable hasn't come up yet. But it could it not also be that these are all, say, Swiss chard, sprouts, and have been distributed over the garden by wind / birds? To my inexperienced eye they look a bit like Swiss chard seedlings seen here (image permalink).
- I have some patches which are still empty, because I'm waiting to transplant some other vegetables there. There are virtually no plants of the type that I'm identifying as weeds in these patches, which suggests that they were in fact sown. (On the other hand, I did not water these patches, which could also explain the lack of weeds?)
Finally, if it is not certain that they are weeds (especially in the Swiss chard patch, for example), is it bad to leave the plants there to wait until they are bigger and can be identified better? Will this seriously hinder the vegetables in growing and/or make it more likely the weeds will return?
