Not knowing the difference between weeds and seedlings could destroy your veggie patch. Be careful in removing weeds to prevent pulling out your vegetable seedlings by mistake. Familiarize yourself with the appearance of the seedlings that you are growing and the common weeds that can grow alongside them by checking available photos online or offline. You can also ask for tips from other gardeners about this.
Check and compare their differences as much as you can until you can properly identify the vegetable seedlings. To make things easier, sow the seeds in a straight row and put labels in front and at the end of each row. Remember the germination period of your seeds so you know when the seedlings will appear. Pull weeds only when the seedlings develop their true leaves. You can also sprout weeds on purpose before planting your crops. Prepare your vegetable plot by putting a clear plastic over where you will sow the seeds a few weeks before sowing them. This will help speed up the germination of the weeds so you can remove them before you plant anything.
