I talk a lot about my garden, and food, and my desire to be more self-sufficient, but I don't often speak of it in the context of teaching my children.
Maybe because I am still learning myself. Every year I plant a bunch of vegetables and hope that they grow. There isn't a whole lot of planning besides what I know I can grow (in pots!), everything else is complete trial and error. But, I want my kids to have the same desire to dig in the dirt as I have.
I think that I am lucky in realizing this while my kids are still quite young. They want to be out in the garden digging in the dirt, it is fun for them to pull up weeds. In fact, last summer I let them plant some of my seeds in a section of the yard they had dug up. It happened to be mustard greens...and they grew quite well...and my daughter was ecstatic that a seed she had put in the ground and diligently (over)watered, grew so well.
Sometimes it is easier for me to do it myself. Actually, it is almost always easier for me to do it myself. But, I do know how exciting it is for my kids; add in my desire for them to be good stewards of God's creation and to learn some of the skills pertaining to gardening, well, I am going to let them be more involved.
I am really excited about the spring planting season this year. I have ordered my seeds, and plan to start some seeds as soon as they arrive. I know that my kids are going to love helping to put those seeds in dirt, and watch them grow, and then to help me plant those seedlings in the ground. It will probably take me longer, and it might be messier, but it will show my kids that I trust them to help me on something so important, and will instill in them the value I place on our food.
