Me picking leaves for the sallad.
The tomatoes drink more than two bottles of water each day. I refill the bottles, but I don't like the sound of roots breaking when I press them back into the soil. To solve the problem I cut off their bottoms to be able to fill them while they were still in the pot.
That was not a good idea. The water ran straight through bottle and soil in no time. I should have realised that it needed some sort of suspension to make the system work, but I've seen tomatoes watered this way outdoors. Outdoor tomatoes, on the other hand, have an endless buffert of soil beneath them. Duh!
This strikes me as a good exemple of mistakes you have to do in order to become a good gardener. The skill improves greatly by those few occasions when you do everything backwards. So, after wiping the water off the floor and replacing the bottles, both I and the tomatoes are happy.
