good job on the potatoes.  Those should do just fine.  I  remember that a neighbor of mine used to have a plant that smelled like lemons and they pressed or maybe boiled the leaves to extract the flavor and then they made very tasty lemonade.you guys should do a bunch of research online about gardening(i am sure u already have). well good luck guys! I have a garden I didn't now what I was doing and it worked! so keep on trying.
