So true, stone. We are approaching our 40th anniversary, and I must admit I'm glad for the limited interest my spouse shows in the garden. He is an engineer, and appreciates symmetry and everything orderly. If he were a gardener, we would have mowed lawn with straight edges . . . etc.
A wise friend says there are two types of gardeners, landscapers and collectors. I am a collector, want to grow one of every type of plant and don't really care how neat and tidy the garden is. We have no lawn at all, and I am happy with my messy little private botanical garden.
So DH helps me with projects, builds garden structures for me, buys me any and every tool that might help me to garden, and asks only that he be able to walk through the garden "without any plants touching me". This alone keeps me busy in Florida in the summer, where plants grow a foot overnight . .. so, yes. I'm with stone on the attitude of appreciating your spouse for their individual strengths and talents and being glad for an interest that can be shared but doesn't need to be.
