5. Remove Weak Plants
It’s not uncommon to notice weak plants growing in your garden. Don’t let this upset you. Instead, just remove them. Weak plants rarely recover from whatever issue is making them weak, and if they are diseased, they could spread that disease to other plants and ruin your entire garden.
Removing the weak plants will also leave yours with plenty of room to plant new, healthy beets. If you already have a lot of beets planted, removing the old plants will allow your other healthy plants to grow larger. To remove the weak plants, you need to cut them down to the ground. You should do this at least twice or until you notice they have stopped growing.
You may be tempted to dig them out, but this could cause problems for other beets that are planted nearby. Once you cut down the plants enough, they will stop growing and eventually dissolve back into the earth.
