How much water for tomato plants in pots?
I am growing tomato seedlings on the windowsill in 9cm pots in general
purpose compost. The plants are about 2cm tall at the moment. How much water do they need? And how often? And do you put the water in the tray and let it soak up into the pots? -- Chris |

On no account leave them standing in water in the trays. |

On no account leave them standing in water in the trays. I am concerned not to over-water. Do you just look at the surface and see if it's dry? There are eight 9cm pots in a tray. Does a litre added to the tray each week sound about right? (I'm trying to get a feel for how much is typically needed.) -- Chris |

I water from above, 1cm(ish) deep whatever the size of the pot, and repeat whenever the soil is dry. If you're watering from below, put about an inch in the tray, and throw away any that hasn't been soaked up a couple of hours later. Feel for dryness rather than look - compost can look damp when it isn't. Get used to examining at the soil and the plants, rather than being prescriptive - the amount of water needed varies enormously with both temperature and wind. -- Kay |

Thanks for your advice, which sounds sensible. Perhaps I should have an extra plant pot, with no seedling in it, for examination of the dryness of the compost. Then I could get a finger down deep into it. BTW there isn't much wind in the kitchen! -- Chris |

I like to think I can water effectively, but for someone new to things like you Chris, the spare pot is great. -- Pete C London UK |

Then I could get a finger down deep into it. Remember the main reason for the soil getting dry isn't evaporation from the surface of the soil, it is because the plant is actively bringing water up from the roots and releasing it from the leaves. So a plantless pot won't get as dry as quickly as one with a plant in it. BTW there isn't much wind in the kitchen! That was a general purpose comment! ;-) (I'm always aware that lots of people may be lurking, just as I learn a lot from the answers to questions other people ask) -- Kay |
