    Default Tips for feeding Tomato plants?

    Hello, we have filled a greenhouse with 12 growbags, each of which have 4 tomato plants in them and the tomatoes are starting to grow now. It is a bit of a pain to water them all now, however I have just bought a hose lance to get through the bottoms of the plants to feed the plants at the back.

    Does anyone have an effective method they use for being able to feed the plants on the days when we Tomorite them? The watering can I feel will damage the plants at the front when I attempt to feed the plants at the back.

    Any home-made ideas or anything?

    Thanks
    Rob

    4 in a growbag sounds a bit cramped, if its a pain to water them now, it will get much worse as they grow.
    If you can push a plastic bottle (upside down, cap removed, bottom cut off) or tube into the compost, you can water into that and it will get to the roots.

    It maybe worth removing one plant per bag? When they start growing you won't get much airflow around the plants which could cause some leaf mould/botrytis etc.

    Bottles sunk in as VC suggest is the way I water my toms in bags and baskets.

    Hi Rob, I’m not growing in bags but when I was considering my set up in the greenhouse before the season started I found this video which I thought was useful. This guy seems to know what he’s doing! Hope it helps!

    Stick some sort of bodged up tray filled with gravel or sand under the grow-bags and water in to that

    Add a short length of hose onto the spout of the watering can and poke it through the front Tom's into a bottle inserted into the back grow bag.

    I agree with every one else about 4 being too many in a grow bag. You'll notice that a lot of grow bags have the holes marked on them for three plants.

    I had three plants in a grow bag in a blowaway last summer and wished I had only put in two, as it was very hard to see what was happening inside the tangle of plants. The growbag had ''cut out' marks for three so this led me to think that was the best number.

    Once I had tasted the Totem tomatoes (v the other tasty two, Gardener's Delight and Red Alert), I doubly wished I had given that third plant a miss!

    It might be too late but, can you get some of the 4ft plant trays and work them underneath, then you can water/feed into the trays rather than the growbags.

    I grow mine in MFBs stood in holeless trays. Water in the tray feed from the top.

    The other problem I always found with using growbags (however many plants you put in them) is that (unless they're all the same) some of the plants will dominate and outgrow the others.

    My dad created an extension to his watering can with a 2ft length of hosepipe and one of those rubber tap adaptors. He cut the hose at an angle so it dripped neatly. Might be able to reach further back without the watering can bashing the plants.

    Whatever you do, good luck.
