I want to help you with this. I am not sure what you're exactly asking for; is it ideas for your zone, or what we do in our own zones during a 'normal' January?
I think you want to hear what we do so you can relate this to new thoughts on your own gardening. I think LOL
OK here goes,
January 2010 (sounds sort of Futuristic)
In January I lay on the loveseat in my living room which is positioned on a South facing window. I spend several hours soaking up the sun. This is a Winter ritual.
I look at the disaster of a house which I have cleaned all year, but for some reason January is a prime 'dust' season. That, and an invasion by every spider that wants to winter it out in the tropics of my home, cause me to realize it is time to take the hose and turn it on in the house. Just start from the outer walls and work my way to the center of the house in the hallway where I have a central drain. I wash everything. I hose off the couch, the tables, the counters, the walls and all my intricate nick-nacks. I even spray down the ceilings.
When I am done everything is sparkling clean! LOL then I wake up on the Loveseat and realize I have had enough sun for the day!

Who want's to do housework!
Seriously, I have always wished for a waterproof home with a central drain all my adult life! LOL What a dreamer!
As for gardening, well, I am an avid 'Winter Waterer'. I am a firm believer that all plants that are overwintering are growing 90% of their new roots. When a bush returns from 'dormancy' and starts to either bloom, leaf, or fruit, the plant only does about a 10% energy expenditure on root growth; instead it focuses on the above ground tasks. So with that in mind I make sure that all of my trees and bushes and hardy perennials are watered normally.
By this time I am also able to break free my assorted annual vines. They are dry and brittle and simply taking a rake across the trellis/fence breaks them off. They come out of everything and are transported to the mulch. I even start clearing out all the beds of any annual debris. It becomes quite tidy and clean out there. I find that there are many living plants interspersed everywhere. Tiny salvias, tiny gaillardias, tiny mallows, and aster are everywhere. Clearing all the debris allows them to get maximum light and not get all rotten from all my watering!
I don't do any pruning in my winter months unless I have to; I don't prune my roses until exactly February 14. This is when they break dormancy and I get to prune everything from the roses to the peaches to the plums and everything in-between. Now don't get me wrong, nothing will actually break dormancy and throw a leaf (usually, if not evergreen), but I can tell that the buds are beginning to swell up and so the 'juices are flowing' so to speak. Typically it is the Globe Willows and the Weeping Willows who throw leaf first. Usually before April 1st. This does not mean we cannot get a late freeze, so there is a secret that I follow (secret is in that I tell everyone!) LOL, that the desert speaks to us through our native Ocotillo plants.
You see, the Ocotillo will not bloom if there is going to be another freeze coming--even the late freak freeze! They seem to know the weather, and once they bloom, then it is safe to put seedlings and plants in the ground. The ground may still be too cold by then, but there wont be a freeze.
OK, getting back to January!
If I do get any Seed/plant catalogs for each season they usually are on my coffee table by then. I love contemplating having everything! I save them for some odd reason. I get more plant pictures online, and I often will visit their websites only to look and read. I find that I am still holding on to seeds that I purchased a few years before and I try to take inventory of what is 'left-over' from my efforts. Some I tried and failed and held on to a portion to try again, and some I have that worked but I only used a small portion. One in mind is
Angelonia
I got white, pink, and purple; I managed to have 6 plants throughout the year and on through last winter. They bloomed nicely and I had hoped they reseeded well. I can report that by Spring of 09', this year, no new seedlings arrived near or around my plants. I did not deadhead, but I did dry break-up the seedheads. Angelonia seeds are 'pelleted seed', because the actual seed is so tiny. For me that means Microscopic! LOL
I liked them! I have all colors kept in tiny glass viles, all 'pelleted seed', so I will likely get them started by January.
I also have my new greenhouse! It is a greenhouse in as much as it is a human-sized terrarium. I am monitoring it right now and it has been enclosed since 10/29.
sorry, same picture as before!
I currently have it running a steady 78 F during the peak of the day on through to evening. By early morning 7 a.m., it is sitting at 48 F. I will be stepping up the heat by adding another radiant heater. These are flat panels. They are the kind of heat that are used by zoos for reptiles and birds.
So, I think by January I will have all of my seeds listed and most started. I know off my head right now I will be doing at least 16 of two separate Mallows/Hibiscus. I want to do a ton more of my Lisianthus (which are still in bloom right now in the greenhouse). I will be doing more Geraniums (this one)
I will start my next season's tobacco and tomatoes in the greenhouse. My intention is to keep the bottom range into the 60's, that and my heat panels I should be able to force with bottom heat. This is all a new experience for me.
By the end of January I will have turned many beds, added compost/manure renderings, and probably began my first series of hand weeding. We get a ton of weed seeds spread through the winds and my feet; plus those odds and ends weeds that took to seed from the end of the previous season (right now!

), but what is nice is that it is all forgiving. Once January comes there will be no more debris and it will be so neat and manicured!
This is all speculation on my part. Here is a picture of my backyard in January three seasons ago.
not much you can do when the weather turns; but, surprisingly we can see this snow one day, and in less than three the last traces are 2000 ft up on the Mountain range. Then the valley warms up again.
Three seasons ago and that same pot on the table is filled with the very same Snapdragons that grow there today! They are pure white snaps with a yellow inner tongue. Amazing!
I will propagate as many Snapdragons this January as I can muster! These will be from all my collected seed so the crossing might be interesting. I consider the Angelonia like a Snap!
I also have some Delightful News! My Birthday Gift Came in from Joe! It arrived just as the sun was setting. There was no time to take pics it got dark fast, but everything was transferred from the plastic into the air in my greenhouse. So from Florida Air to Greenhouse New Mexico Air. I used distilled water to hydrate everything.
So by January I will have an incredible display of Airplants that will undoubtedly integrate into my other Birthday Gift to myself. I am going to start some Hypertufa projects. I bought myself 3 cu. ft of peat, a bag of perlite, vermiculite, and Portlands cement. I also plan to do cement carvings/sculptures. I think it is time to allow the artist in me and the plant lover to merge into a product! I have been out of the Farmer's Market for over a year now. Time will tell; at least by January I will know the direction! I do like alpine, but then that is hard for our region...expensive plants. I am going to have to be creative! Most definitely the Airplants and my newest collection two more Epiphyllums will keep me focused.
This site I liked because it has every shape and the pricing is a thought on any projects that I intend to sell. I find this very helpful because I am guilty of underestimating the value of handwork.

I dig this concrete carving! I am so addicted to the thought of it. Here is a link to an Artist in New Mexico who teaches classes on his technique. Inside you will find the link to their gallery, and see the handiwork of the students. It is awesome stuff! He gives great online instructions and pictures. His recipe and technique are there for everyone! How cool is that?
Sandpudding.com I like the name, and now my inspiration has escalated into enthusiasm for doing this! I hope more folks consider this project this January!
OK, I guess I exhausted this post. I enjoyed documenting my thoughts. This was an effort that lasted over several hours. I managed to write all of this between no less than 10 breaks! LOL Whew! :mow
Is it January Yet? LOL :tools
