Removing Tomato Leaves
Years ago, I watched a TV documentary on tomato growing. The
grower was asked why he removed all the leaves from his plants, and he said that he supplied all the nutrients they needed, and he wanted it all to go to the fruit, not into the leaves. He was growoing in I think a heated greenhouse. Does anyone do this to their toms? I'm wondering this year, as they have made an awful lot of leeaf growth in the greenhouse (cold), and I would like to get as much sun onto the fruit as possible, giving the weather we are ahving. -- Roger T 700 ft up in Mid-Wales |

I'm wondering this year, as they have made an awful lot of leeaf growth in the greenhouse (cold), and I would like to get as much sun onto the fruit as possible, giving the weather we are ahving. I grow tomatoes in an unheated polytunnel and was told by an experienced gardener a few years ago to remove the lower leaves, up to a foot to 18 inches above ground, to allow the air to circulate which would cut down the chances of mildew developing. Since adopting this procedure, I get less mildew than I used to, but I don't have any plants without leaves removed, so no control. The gardener at a local commercial garden removes all the leaves once the first fruits are ripening and seems to share the view of the TV grower. Looking on the internet also seems to produce no consensus on how many leaves to remove or, indeed, why do it at all! Sorry but I don't thin I've ever heard anything so daft. You can give the plants all the food you want but the plant still has to process it into a form it can use. It would be like giving you a bag of flour a bottle of water and some yeast and a bit of salt. It would take your skill and know how to turn it into bread. You might get some fruit on the plants but it would be tasteless. I would strip off the leaves up to the truss that is ripening but no further, this will help the light get to the fruit and give you a more even ripening. Look at the Large growers such as Thanet earth and they only strip to ripening fruit. This sounds more like a wind up than a serious question. reminds me of an Italian lady I had a a customer many years ago, her neighbour told her to remove all the flowers from her cucumber plants, luckily she asked before doing it. |

The grower was misguided. Leaves are essential because through photosynthesis they produce carbohydrates which the growing plant (including the fruit) needs. Added nutrients can not do this. By all means remove leaves that are starting to wither or showing signs of disease but keep the healthy ones.. R. --- This email is free from viruses and malware because avast!

Isn't it recommended with grapes, too? Ripening is hormone-controlled, and that hormone is mainly ethylene. Since ripening can occur in the dark (such as putting unripe fruit inside a paper bag with ripe bananas to help ripen it), light isn't required. Just another one of the old gardening chestnuts which abound (I'd love to know how the idea of tying daffodil leaves in knots after flowering started!). Maybe it would liven up Gardener's World if once every episode they examined an old gardening chestnut to see if there was any truth in it. -- Jeff |

The idea of tying daff leaves in a bunch is just to keep the place tidy without cutting them off and thus denying the bulb of that feed they still can send in to help develop it for next season. |

I have six tomato plants in the greenhouse. A friend told me to remove the leaves to encourage more fruit. I removed the leaves on three of the plants. All the plants have produced lots of tomatoes. The ones without leaves don't taste as good but that may be all in the mind.

Removing Daff leaves: was removing Tomato Leaves

Another 'old chestnut' David. Research was carried out in Cornwall many years ago and it was found that cutting off the leaves immediately after flowering, greatly improved the bulbs for the following year. The leaves produced before flowering are producing the nutrition for the following year. Allowing the leaves to die back increases the risk of introducing virus, fungal disease and in particular eelworm into the bulb. I cut my daff leaves immediately after flowering and the numbers and health are increasing year on year. Ardmhor |

I leave a few stubs so I know where the bulbs are to avoid chopping them into bits with a spade or digging them up completely.
