Oncidium starts from "backbulbs": Update

Today is my day off. I went for physical therapy for my neck disk, now back home. Before starting "homework", I checked the orchids, watered them. I accidentally noticed the baggy-with-sphagnum-backbulb system that was set up 4 months ago. Buy "set up" I mean, I had cut the backbulbs off the original orchid (Oncidium "dancing ladies"-type) , wrapped them in damp sphagnum moss, placed them into a ziplock baggy, zipped it shut, and left them in an east windowsill. I forgot to record when I started this "experiment". I'm thinking September. That would be 4 months ago.

As I discovered the ziplock bag. Barely visible sprout in the baggie. Cool!

Out of the bag. I couldn't resist. Plus, I wanted to re-position the sprout so that it gets more light.

This plant, started from another backbulb at the same time, is further ahead. growth is slow - after all, (1) it's an orchid and (2) it's midwinter and (3) I don't know what I'm doing. Still, it IS growing.

Flowers on the original plant. Photo taken January, 2008. Although the plant isn't in bloom yet this year, the new bud spike is growing mm by mm.

So now the starts are back in baggies, but separate baggies. The sprouted start is in my home office along with the other orchids, still in baggie because roots have not sprouted yet. I think they will come when the new start is bigger, and roots don't grow from the old backbulb.

Seed Germination Experiment: 2 days (60 hours)

Interesting result so far. I planted Sunday am, now it's Tues pm, roughly 60 hours.

So far, very early, quite a lot of germination. This is a test of the packets to see what I can use this year, not a randomized-controlled trial of effects of age on germination. Still, it's interesting. The warmer certainly doesn't seem to hurt, and may well help.

The cat, of course, needs to get to the middle of it all. Probably thinking "this is where that large lumbering animal opens the little packages of yummy stinky fishy stuff for me. Maybe it will open one now! She then walks across a paper towel - well, no longer any semblance of sterile :-)

I did add another sheet of paper towel to each bag. They seem too moist.

We'll see how they look in another day or two.

Baby you gotta put me on your healthcare plan...

This has nothing to do with living greener, gardening, pruning, or puttering around the yard. Unless you get a pulled muscle (which I have) or chop off the end of a finger with the pruning shears (which I have done). It's just that I spent all day today (Sunday) doing "homework" - except that prior entry - and needed a laugh. I love this video diversion before heading to bed.

Garden Log: Testing seeds for germination

As planned, this is the start of the germination testing for old seeds. The objective is to determine which packets might as well be composted, and which ones can be planted for this year's vegetable garden. I haven't done it this way in the past, so it's an experiment.



Two generic white paper towels, marked with squares and labeled with the seed varieties and year. The year is the year to sell, so they were one season old at that point. I wanted to test tomato varieties, peppers, and beans. There were also some squash, spinach, radish, and Chinese parsley seeds, so i thought, "why not".

The seed sizes are quite different, but I don't think that matters.

Covered with a paper towel, and very carefully slid into zipper type plastic bag. I did not lift them from the table, just slid, to avoid spilling seeds. This was the most difficult step, especially for round seeds.



I used a tablespoon to add water to the paper towels, about 1-2 tablespoons to each square. This was challenging, again trying to avoid spilling seeds from their designated squares. The labels became more visible when the paper towels were moist. Most of the seeds stayed in place. Once moist, they don't move around much. These photos are also my record, in case the labels become nonlegible.

Then moved to the seed warming pad. My main concern is that the pad is designed to have a seed flat sitting on it, and this method may cause overheating. It's not an exact science. I may give in and buy a thermometer. Regardless, it's a few months to seed starting season, so if this doesn't work, I can try again.

Garden Log: early pre-prep for new apple trees.

Not much to report.

I dug out 2 2-ft diameter circles of sod in the front yard. These spots are in preparation for the superdwarf apple trees that should come via mail order in a month. I mixed in some vegetable garden soil, and threw the old sod onto the veggie patch.

Now it can "cure" a month and will be ready when the trees arrive. I may mix in some additional organic matter, although my own compost is in a waiting mode due to cold.
