Q.rutabaga plants
How long do it take for rutabaga plants to come up? I have planted them and I am still waiting for them to come up.

The best way to determine germination and growth rate of your seeds is the back of the seed packet.
Did you plant directly in the ground or have you started your seeds indoor in seed trays?
Temperature and moisture are very important for seed germination.
