tomato time

Hard to believe it, but it is tomato seed planting time in Texas (which probably sounds ridiculous to those of you shoveling snow in northern regions). Each year our 3rd grade gardeners plant tomatoes from seed under grow lights, usually around the third or fourth week of January, to transplant outside the first week of March before spring break. Our goal is try to get the plants ready to harvest before school lets out and also before night time temperatures stay above 75 degrees F (tomatoes will stop setting fruit when the nights are this warm thus tomatoes are spring and fall crops in our area). We usually plant cherry tomatoes because they have shorter days to maturity rates than most other varieties.

This year, in addition to planting tomatoes under grow lights, we also have tomatoes growing hydroponically in an AeroGarden Farm hydroponic unit.  Contrasting the two has been an interesting endeavor. The hydroponic tomatoes have grown so much faster and look so much happier than the ones growing under lights. The pictures to the right shows both 2 weeks after planting. Eventually down the road, I know the grow light tomatoes that we transplant outdoors will over take those being grown in the hydroponic unit, but it is amazing how vigorously they are growing in water. Below (and above) are pictures of the hydroponic tomatoes at 3.5 weeks. The growth rate truly is remarkable and everyone is enjoying watching the tomatoes change daily using this new growing technique.

Another first for our garden this year, we never had a true winter freeze so our fall gardens are still growing strong.  The lettuce beds are full and there are so many sugar snap peas on the vines that the plants are falling over. We are going to break some hearts in two weeks when we have to pull everything out to prepare the soil for our spring gardens (the sugar snap peas have been popular snacks at recess time). Our wildflowers are already blooming too. What will the spring hold I wonder? I am sure there will be many new lessons to share (and a healthy crop of weeds and insects too). Just goes to show that no two seasons are the same in a school garden. Even if we buy the same seeds, plant at the same time and provide the same care – the garden is an ever changing adventure for our young and young at heart gardeners. Never a dull moment in the garden classroom!
