This is a great post. Thanks for starting it, and I really like hearing about what others are doing and their challenges.
2018 was a big year with renovating our old house and selling our 2.75 acre property including my awesome garden (5 4x50' raised beds, 20x25' herb bed and tons of fruit trees and bushes) I've nurtured for 24 years. But, that got us out of the big city and into our 11.5 acres in the pines of northern Idaho. There is cleared land around the house thank God (fire danger and all). So this property is a clean slate for creating our permaculture oasis. Right now we're planning where our new shop/garden building will go as well as the greenhouse, the garden beds and the hugel mounds. It's a lot to consider but I'd rather plan carefully for the major items. The greenhouse will have geothermal heating and be somewhat below grade. The house was built with geothermal tubes going into the foundation and venting into the house and we freakin' LOVE it. It can be 14F outside and without any heat on (zero, zip, nada), the inside is at 54F in the morning. Or it's 95F outside and inside it's 72F, so no AC needed. I can't say enough about the cost savings of geothermal. Our house is well insulated so that's part of it.
We haven't decided yet on solar power for the greenhouse. The plan is to not need much except for lighting and running fans.
I don't know how much will get done this year but last year I didn't have a garden to speak of since we sold in early summer. I did get a lot of garlic from the garden but that's all. We were too busy to plant early veggies or greens and the garlic was from planting my favorite way the previous fall - "toss the sprouting cloves onto the beds and see what happens."
We've been working on the inside of the house since purchase so other than clearing a few hundred "pecker poles" and medium sized dead trees to thin the nearby forest we've not done anything outside. We plan to get the shop built, deer fence (or don't bother with a garden, tons of deer and elk), maybe get the greenhouse built, build a few garden beds, chip the wood except what we need for heating (which isn't a lot) then inoculate with mushroom spawn, build a couple of hugel mounds, and... good lord that's a lot to consider for this year. Ah well, I always work better with a little pressure and a lot to do. Whatever gets done, we plan to do it with some thought so that it doesn't need to be redone unnecessarily. Riding that line between planning and not getting anything done vs. building too fast and not liking the results or having to redo. I'm sure we'll have a lot of successes and failures but that's the fun.
