I'm interested in looking at historical soil temperature data for the DC area - I have found lots of forecasts online as to what the soil temperature will look like in the next few days, but I haven't found any as to what the temperature looked like historically. In particular, I would be interested in looking at what the soil temperature was in any given day or week in the past few years. An added bonus would be some sort of general summary similar to weather summaries that say "in January in DC, temperatures average x-y degrees"
I've been seeing ice on the tops of puddles when the low temperature for the day is forecast to be low (2 or 3 degrees) but not freezing. Why is that? [more inside]

I've planted a variety of trees around my house - kwanzan cherries, tulip trees, flowering crabapples - and many seem to have shared problems. These are 1) extra thick trunks for their size, 2) a tendency toward something like witch's brooming, and 3) a tendency to grow off vertical. No basic nutrient problems on soil testing, but haven't done trace minerals. Should I break up with them, or is there someway to work this out?
I suck at gardening. Past gardening efforts have ended in disaster (bug infestations, groundhog eating everything, plants dying for no obvious reason that I can see). This year, though, I would like for it to be different. I would like to grow my own leafy greens--kale, spinach, lettuces, chard, collards, etc. I'm not so interested in other things like tomatoes and peppers. Do you have any advice for exactly what I need to do to grow great greens? [more inside]
Should the capillary action which will allow water to soak upward from the bottom of my self-watering planters be a factor in selecting a potting mix for Arrowhead Vine houseplants, or is the ideal potting mix the same regardless of whether they receive most of their water from the surface? Also, what would be the best lightweight "filler" for the bottom portion of the planters? [more inside]
Because of the federal government shutdown, the USGS website has been shuttered and all the data that I use regularly has been taken offline. I need to find a source for the "Official Soil Descriptions" [google cache works now, but I anticipate this will last a while, so I need all of them] and the soil survey layers for the state of Texas. Any idea where I can download these?
New England dirt is brown. In the south, it's red, and in other places it is almost black, or more like tan. Is there map that shows dirt colors throughout the US? Or even just an article or two about regional dirt colors? Please point me in the right direction, dear Mefites! [more inside]

Now that I have a balcony, I wanted a little garden out there with window boxes. I purchased window boxes and a bag of Miracle Gro online. I already had two potted flowers that were about to burst from their pots. (I was going to buy more tomorrow after the boxes arrived and I had an idea how much room I would have.) The Miracle Gro arrived and despite no warning on the website, it says "Not for use in containers." Will I kill my flowers if I go ahead and use it? [more inside]

We have a new house and huge yard. We're eager to fill it with plantlife. In fact, we're a little too eager and found some good prices, so we already bought over 200 seedlings, half of which are kale and chard.
