We keep two pots in rotation, since it takes several days for them to sprout, and no matter how much you water it, it withers up and dies off.
James Bond, my Wegie mix, loves to supervise the planting. Early in our relationship, Dear Husband volunteered to plant the next batch, and since we were out of seeds, he picked some up from the hardware store, a different brand that I usually get.
Mr. Bond was very skeptical about the job DH might do. He likes to fetch us to come look at the dirt in the pot and reassure him that it will, indeed sprout. This time, he asked a lot, thinking DH might have messed it up. The joke was on us; this brand of kitty grass, instead of growing about six inches high, grew two feet long! It was spilling over the pot!
We decided it wasn't as tender as our usual brand, and didn't get it again. But during those weeks, Mr. Bond decided that when it came to kitty grass, DH is THE MAN!
