My hubby is not that career oriented but he was (and to some extent still is) a hard core city boy. That is changing more and more all of the time. These days HE is starting to talk about moving out of the city.
Like several of the others have said, it needs to be HIS idea ... or at least he needs to
think it was!
You just start homesteading right where you are and gently suck him into it!
Here is an example.
MY hubby has always liked Mexican food and salsa. He particularly likes eating the hot peppers. With that knowledge I started a steady (sneaky) campaign to get him hooked on gardening!
Step 1 ... year 1. I planted a single jalapeno pepper plant in my front flower bed right beside the steps. Every day when he got home from work it was the first thing he saw when coming into the house. I never mentioned it. Then one day he asked about the plant because he had noticed the peppers growing on it. I still underplayed it and never picked a pepper. One day HE came in the house with a hand full of peppers. "You know those peppers were ready to pick. Why haven't you picked them?" That night we had nachos and peppers for supper.
Step 2 (year 2) I planted a single jalapeno pepper plant - this time in a big flower pot ON my porch beside the front door. After it was going good I would often "forget" to water it. At first I would leave a bucket of water fairly close by, like I was going to do it but got distracted somehow. Hubby would come home, notice the wilted leaves water the plant then come inside and fuss at me for not keeping it watered. He also started looking for peppers on the plant. About half way through the summer I started asking him if he had watered HIS plant. Sometimes he got a bit cranky about this, but usually he had already tended it.
Year 3 (step 3) I acquired 3 BIG buckets (they used to hold cattle minerals) and fixed them up with compost. The next time we had to go to the hardware store for something I
kind of noticed the pepper plants. "Have you ever eaten a poblano pepper? How about a serrano chili? Why don't we plant them in those new buckets? ..."
These days he has the whole porch FULL of different peppers and a paste tomato (to make salsa of course!). He has purchased water meters and fertilizer, and even started his own seeds! He even roasts the peppers and makes his own salsa! When he comes home from his often stressful job he always spends a few minutes on the porch before coming in ... just petting his pepper plants!
It CAN happen!
