Dandelion Watch

A few posts back I mentioned phenology and how the study of dandelion bloom times can be used as a soil temperature indicator. However, at the time I could not find anything online relating to the actual study and recording of these observations on a larger scale.

Well, look what I found! Dandelion Watch, an Environment Canada initiative that is asking the public to watch, observe and record dandelion bloom times in their area. The collected data is then being used to track overall climate changes across Ontario. There are also a number of related Environment Canada watch initiatives to contribute to including: Plant Watch, and Worm Watch. Fascinating!

Andean Potato Farmers Fight Terminator Potatoes

A friend pointed me to this interesting article about a group of indigenous farmers in South America who are taking the multinational corporation Syngenta to task against terminator potato technology that they fear will cause extensive harm to “their region’s biodiversity, culture and food sovereignty.”

“Peru and its Andean neighbours are the potato’s centre of diversity — with nearly 4,000 unique varieties that farmers have developed over generations. Before reaching its position, the coalition undertook a lengthy discussion with farmers across the region.

Farmers are concerned that terminator potatoes will enter the Andean production system and destroy their traditions of storing and exchanging potato tubers for future planting. This is central to the farmers’ culture and has contributed to the region’s immense diversity of potato varieties. They also fear that pollen from the modified potatoes could contaminate local varieties and prevent their tubers from sprouting.”

Secret Gardens

I’ll be traveling to Hamilton, Ontario this Sunday to do a book signing and give two presentations at the Royal Botanical Gardens. Giving gardening presentations and workshops has become a regular part of my spring schedule yet it is something I rarely seem to talk about here. What’s worse is that I have been noticing a growing disconnect between the things I add to the site and the things I talk about at these events. Looking back I think it’s got to be the fact that I am so exhausted by the end of spring that I just kind of move on and lose the excitment to share. Last spring I wrote, designed (with photos) and gave eight completely lectures within a months time! My New Year’s resolution is to start integrating all of these different aspects into this site.

One of my favourite things about speaking to groups is showing photos of the gardens I find in the craziest places. My attitude is that if these people can pull it off, anyone can! I have taken to starting off many presentations with the following photo since I think it’s about the most successful worst garden I have ever encountered.

I first found this little tomato patch a few summers back while wandering through the alleys of Toronto. Toronto has an exceptionally great alley system that is an interesting (but sometimes indirect) system for walking or biking from point A to B if you’d rather stay off the beaten path. People are less concerned about the back of their house so there is a lot of hidden gems and bits of history that has been left in place.

But I digress. Every summer a group of artists borrow the garages of a local system of alleys to put on an art show called “Alley Jaunt.” I found this little cobbled-together raised bed sitting behind a garage while out exploring these temporary garage galleries. A year later I came across the same garden while on another Alley Jaunt. This time the gardener responsible was there tending to and harvesting an impressive patch of pole beans — his own version of crop rotation! Unfortunately the elderly gent spoke Portueguese and I do not so communication was impossible. I tried to let him know how impressed and inspired I was by his garden as best I could and then went on my way.

Don’t Plant, Do Plant

I came across this “Don’t Plant a Pest” brochure put out by the California Invasive Plant Council that could be handy for those of you in the Bay Area. I like that instead of listing invasives with a stern warning against planting, they offer reasonable alternatives and solutions.

Amateur Phenology

So. Ummmm. Who’s a little freaked out by this crazy weather? They say Canada is totally backwards especially for an El Nino year with the west coast all wet and wild and the east unseasonably warm and snow-less. I’ve heard that things are also a bit nutty in parts of the U.S and my Northern California friends are talking about super early magnolia blooms.

Just today I received a frantic phone call from my friend Sarah announcing that she had just spotted two yellow, blooming dandelions on her street. That’s exactly how she said it, “Mark this down: two blooming dandelions, January 4, 2007, Toronto, Ontario.

Sarah also mentioned that dandelions are known as an indicator of weather patterns. Apparently there are people who record when the dandelions bloom in certain areas. While I do know that this kind of pattern study is called Phenology (as gardeners we are all amateur phenologists in some way), I have been unable to find information relating phenology specifically to dandelions. However, this article states that blooming dandelions indicate when the soil temperature is “… between 50 – 55 degrees. That is the same temperature that soil microbes become active, so dandelion flowers are a nice indicator for when the soil is waking up.

I truly hope my soil is not waking up.

Actually I’m pretty sure it is. Here’s some photographic evidence:

    First up, the crocus is out. No buds yet but I am fearfully watching and wonder what this will mean when ACTUAL spring comes along.

    The pansies didn’t actually stop. Pansies are quite resilient and will often keep blooming until the hard chill really kicks in. The container plants give up much earlier since they are much more exposed to the cold.

I have also noticed that a lot of other early spring risers are coming up in full force. These include perennials and self-seeding annuals such as: artemisia, globe thistle, anise-hyssop, grasses, and giant red mustard. I am not particularly concerned about the long-term welfare of these hardy plants but am worried about how this will fare for the more delicate of the bunch.

Anyone with further interest on how warming has affected gardening may want to check out this cool map of the U.S (Sadly I could not find a Canadian equivalent) that shows how the hardiness zones have been changed to reflect overall climate change.
