Saving Lettuce Seeds

Various Loose-Leaf Lettuce Varieties Bolting

Lettuce has been around for centuries. According to Wikipedia, the Egyptians first cultivated lettuce as edible leaves as early as 2680BC. It then made its way to Greece and Italy where it flourished.

Today, we see four main varieties of the species, Lactuca sativa, in our backyard or school garden. These include:
Crisphead or Iceberg
Butterhead, Boston or Bibb (which is also a heading lettuce)
Romaine or Cos
and Looseleaf or Leaf Lettuce

Romanesco Broccoli and the Fibonacci fractal

Romanesco Broccoli is a variety of the species Brassica oleracea. It is a cool weather crop that enjoys a steady diet of nutrients. We fertilized with fish emulsion every other week.

The beauty of Romanesco lies in its unique flower structure. When we consume Romanesco, other than the stems we are eating flower buds.

These flower buds are very well known in science circles for being a natural example of the Fibonacci fractal. In mathamatics a Fibonacci fractal will go on forever, ad infinitum. A broccoli plant obviously does not go on forever, but the pattern does repeats itself in every bud.

This article explains it well, Fibonacci-Shaped Romanesco Broccoli Is the World’s Most Visually Stunning Vegetable

See other natural fractals in this Wired gallery.

Other than being really healthy for you, Romanesco broccoli is a cool way to bring math into the classroom.

Here’s one place to purchase seeds, Baker Creek Heirloom Seeds.

Winter Tomatoes – How to Clone a Tomato Plant

winter tomato

If you live in an area with mild winters, or if you are lucky enough to own a greenhouse, winter tomatoes can be easily grown. The trick is to clone a tomato plant from your summer crop. A clone is an exact replica of the parent. And since it is a clone hybrid plants can be used as well as open pollinated heirlooms.

Procedure

1. In the middle of July when your tomato plants are healthy and robust choose a side shoot that is without flowers and cut it about 6-8 inches from the top. Caution, do not cut the main grow tip.

2. Put it in water and allow the fine hairs on the stem to develop into roots. Cut off any existing flowers, at this stage we want the energy to go into making new roots and leaves, not flowers.

3. Once you see the roots developing plant them in soil so the new growth is just above the soil line. Keep it well watered during the early stages to allow the roots to develop. A little nutrient fertilizer would be good at this point.

Tips: Thicker stem cuttings did better than thinner stems. Choose smaller tomato varieties like cherry tomatoes or medium sized varieties. Since the daylight hours are shorter in the winter don’t bother with the large beefsteak varieties, they will never get that big during the winter.

Lastly, the tomato plant above is a Japanese Momotaro. In the early Spring we plan on taking a clone from the clone and seeing if it takes. We’ll keep you posted!

Obesity, Nutrition and School Gardens

In America, more than one third of US adults have obesity as well as one in six children.

The cause and the blame can be researched and debated till the cows come home and still we’ll be in the same place as we are right now. What are we going to do about it?

school garden harvest

One approach is to teach nutritional education through school gardens at the elementary, middle, and high school levels.

Human and plant nutrition are inextricably linked, we share many of the same essential elements. The more we understand plant nutrition the more we will understand human nutrition and vice versa.
