It's a new year, again.

Pruning Concord Grapes
Perhaps I can do better this year, both in pruning grapes and putting garden information here.

Right now the snow is still pretty deep in the yard, after a particularly snowy and cold winter. One advantage of the deep snow is that I could see and reach over the grape arbor. Before that I did some more research on pruning Concord grapes and this time it made sense to me. I certainly could comply with that part suggesting that about 90% of the growth should be pruned off. The question, of course, was which 10% to leave. I now understand how to leave a spur behind to grow into next year's fruiting canes. But not having understood that before I did not find any one year canes near the "trunk" of the grape plants.

I cut away all the old, dead canes, the small (clearly less than pencil thickness) one-year canes and canes that were right next to, or over, better canes. I think I have left plenty of buds and tried also to leave some single bud spurs that should become next year source of new fruiting canes. If nothing else I felt like I knew what I was doing. I am sure that one big problem last year was so much growth over the arbor that the fruiting canes did not get enough sun. The other problem was leaving too many one year canes. Hopefully I did not do that this year. And equally hopefully I did leave enough one year canes to have a decent harvest. Last year we had 14 lbs of grapes as opposed to 70 lbs the prior year.

Seed starting has started. I started parsley and leeks on March 6th and the leeks are just beginning to break the surface of the soil. I used what is labelled "John's potting soil" but I don't have a clear recollection of what it contains. I know that I froze some vermicompost and I would think that the rest is OCRRA compost.

Tomorrow is scheduled to be a big seed starting day - lettuce, kale, collards, spinach (yes!, starting it inside), peppers, red orach (whatever that is), broccoli, scallions, and some more parsley (because I didn't have the new seeds on March 6th).

Is it the potting soil?

What am I doing differently this year such that my seedlings are not growing well? The tomatoes (left) and peppers (right) that I started on April 3rd have germinated but have not developed as they should. Admittedly I started them later than I wanted to but these little plants represent seedlings that emerged four weeks ago. The same is true of most of my other seedlings. The lettuce I transplanted this week are the smallest little lettuces I have ever planted out. That is also true of the broccoli, zen and kale that I have now transplanted.

My suspicion is that the potting soil I used after I finished up last year's bag is the cause. I know that a lot of sources on starting seedlings say to not use commercial potting soil but I have never had a problem. What I have been using the last several years is Miracle-Gro potting soil (the bag also says that it feeds plants up to six months). When that ran out this year I bought what I thought was the same - well, the color of the bag was the same - but I think it was Scotts Premium Potting Soil, which, according to their website, is intended for container gardening. I knew that it was different when I opened it because it was fairly coarse and full of little chips of mulch and woody stems.

The seedlings I grew thorough the winter to try out in the cold frames did not have any problem but they would have been grown in last year's potting soil. The most recently planted seeds also seem to be doing well and would have been planted in potting soil from a new bag of Miracle Grow. It is what I started in between - that is, using the coarse potting soil - that has not done well.

Since the soil around these seedlings, when I knock them out to plant, is very wet I suspect that this potting soil is a type created to retain moisture. On the other hand I have also changed the way I water the seedlings, using a little watering can and watering from the top as opposed to my prior method of pouring water into the bottom of the tray in which the pots are sitting and then draining it out a short time later. But I don't really think this would change the amount of moisture retained by the soil in the pots.

As a result of the slow growth, I have been planting seedlings into the garden that are much smaller than what I would normally plant. Time will tell if they will thrive. They may have been in too much water too long and can't recover in the garden soil. [The tiny lettuce plants seem to be doing okay, however.]

Also today I transplanted the tomatoes and peppers into larger containers using the newer potting soil. Hopefully they will soon be smiling back at me - and growing.

I'm Getting a Slow Start


Maybe I am misled by the warm spring we have had so far, but I seem to be behind in my "regular" gardening. Working on building cold frames and trying to get some greens started early in cold frames I have been late in starting seeds for the garden. As a result I have peppers that are just beginning to form their first true leaves and tomatoes that certainly don't look like they will be big enough to set out later this month.

I am concerned about the potting soil I used. It retains a lot of moisture so that some of the seedlings that I set out were sitting in dripping potting soil. But they certainly have roots. I am mostly concerned about the growth of the seedlings. Several days ago I planted out the smallest lettuce seedlings ever. But, knowing that lettuce is pretty hardy (and that I have bunches more still in their little containers), I set out about 60 tiny seedlings. I put them in the frame that I used for the winter lettuce and, later, the early Asian greens and covered the frame with row cover material to protect them from too much sunlight. Hopefully the slugs won't find them immediately.

I have also set out celeriac - although this may be too early as I have read that they will bolt in the warm weather. Anyone with experience with celeriac, let me know. The parsley is in - now that it is large enough so that I can distinguish it from the cutting celery. [I didn't label the containers.] I have planted potatoes and set out more leeks yesterday. I planted the leeks by dropping them into holes made with a dowel. Usually I dig trenches and plant them in the bottom and then pull the extra soil over them as they grow. I'll see how this method works because it is certainly easier and allows more leeks in the same space since there isn't soil piled up along the sides.

We may now be where we are producing enough of our own greens that we don't need to buy them at the grocery store. The Asian greens (Chinese cabbages, komatsuna, and pak choi) have grown well and are ready to eat. We have been working on the lettuces that I planted out in the cold frames earlier. [The winter lettuce have been gone for some time - how long will 22 lettuce plants last?] We have been eating last year's kale and scallions and have started on this year's zen and spinach.

Now, since I am already late, I need to start some basil, more kale and squash inside, and fava beans and scallions outside. From the limited way in which scallions have germinated inside this year I suspect that the seeds have lost much of their viability.

And, just as I finish this my wife spotted a nice fat groundhog in the back yard with something nice and green in its mouth. Guess we didn't get them all last year.
