The tomato seedlings are looking great.  Some of them are getting quite tall in fact, so tall that they might need some support before long.  If your tomatoes are getting very tall and thin, you can support them with disposable bamboo chopsticks.  Stick the chopstick into the soil 2 or 3 cm from the base of the plant, being careful not to damage the roots.  Gently and loosely tie the tomato to the stake, perhaps with a wire twist tie.  This will make your tomatoes less likely to break, especially when you bring them back to school.

The tomatoes I took home have only needed watering once so far.  When you do water, don't add too much.  The soil shouldn't become too water-logged.

I hope everyone is having a great break!
