FROSTY GARDEN UPDATE

Brrrrrrrrr, I moved from Michigan to California, to warm and balmy weather – right?

Let’s talk 12 degree nights this early December week, and my garden is uptight & hunkering in – as are we all!  Glad to be a human with a warm house, flannel sheets & cuddly guy in my bed…

As for my garden beds…well, i crunch around on the frozen mulch, and take a look…they are all frosty until almost noon, then have a brief fling with the slight winter sun until the poor things get shaded again and start to cool down.  I took the covers off my fabulous straw bale beds at 11am & put their little faces to the sun, gave them a deep drink of water, left it all open until about 4pm…which was too late, really – I lost a bit of gathered warmth, should have been open from noon until 2:30 maybe…

Soil temperatures continue to please me, the soil in regular raised beds was 35degrees at 6 inches deep noted at 11am, but the inner straw bales read 55degrees!  I MUST get an air temp measurement inside the covered beds to see if the “greenhouse effect” is working…

Also – want to figure out an end cap, as the ends are poorly gathered up, and loss of warm air to a cold/warm exchange must be happening there…maybe heavy cardboard cut to fit the hoop shape, and clipped on…

Eating fresh tree collards & cabbage that is holding up rather well despite the weather…hoping for rain tomorrow, and warming temps…

How to survive in case of global cooling…how much greenhouse fabric can we realistically use?

Straw Bale Planting Beds –Building with bales!

WATER RETENTION

Last seasons garden was semi successful…I was happy to be planting a garden in the 5 raised beds bequeathed to me in this wonderful vintage home.! I discovered that this soil was also quite vintage, and so last winter we used each bed in turn as our compost pie. Then, in early spring I amended the beds with oyster shell, perlite, azomite, chicken manure, rock phos & other minerals. I was so used to dealing with the hard clay of my former garden, unfortunately I went too far toward building a permeable soil – and spent the dry summer dealing with a very silty soil that does not hold water well. Luckily, I have been continuing to make plenty of compost, and will correct that problem very soon. In the meantime, I am trying a great experiment in water retention & mulch for this winter’s garden. Frey Biodynamic Organic Winery is using these innovative straw bale beds in their old parking lot. Instead of tilling the compacted & hardened soil, they brought in a number of straw bales, made rows and proceeded to plant right into the bales, by cutting holes or “rows” & adding soil into those areas for planting. After 3 years the original beds are now made of wonderful humus about 4” deep, and the original soil underneath is getting healthy too! They inspired me to try this method in my raised beds. I brought in 4 straw bales, and laid them onto the soil in the bed, first removing about 3 inches of soil to use elsewhere. I was having a hard time cutting the straw until after the first rains, when it was really soaked through. Now I could more easily cut, reach in & grab handfuls of straw to remove until my hole was deeply set, and my little starts would be happy in a small bit of soil set into the decaying straw. It was a decent soaking rain, and I felt confident about planting now.

STEAM HEAT

An interesting development! As I was reaching into the first hole, I felt extreme warmth inside the bales. Richard has a compost thermometer, so he inserted it into the bale, and – wow! It was a 60° day, but the interior temperature was almost 140 degrees!!! Over the next week, as the bales slowly dried out, the temp went down to 120°, then 100°., then 80°, where it has stayed for well over a week. Today the soil temperature was 60 degrees in the rest of the garden, and the straw bales remain at 80°. The starts are doing just fine, not extraordinarily so – but showing normal growth rate for this cooling time of year. My hope is that they will get an edge from the heat, and in fact – I am going to use bales in another bed for some spinach, normally almost impossible to grow here in winter. I will use the hoop bed (see rear of picture) and add a “greenhouse” cover to it soon. The hope is that the decaying straw will add warmth to the interior of this mini-greenhouse – heck, I may be able to put my lemon trees in there!! And, then – next spring! Head start on tomatoes!! Ok, I am getting ahead of my self, but am very excited & hope to be reporting positive news in the next months – from this little experimental bale garden.
