Why didn't I get any tomatoes ?

Question

1st time growing cherry toms. 3 plants in a grow bag with a cane each, lots of flowers then they just fell off. I watered and fed them and kept them in a mini plastic grenhouse, where did I go wrong. (they are the tall type not bush type)

Answer 1

Mini greenhouses are great, but the ventilation can leave a lot to be desired. Choose a variety that will grow outside & start the seeds off in the mini greenhouse. Move them to a sunny wall once they start flowering (assuming the frosts have passed) - keep them to 3 or 4 trusses maximum and pinch out the side shoots - you should have no problems next year.

Answer 2

Small greenhouses get Tº´s over 90º really easy, long periods with Tº´s over 90º F could cause flower dropping. Feeding the plant with great amounts of Nitrogen at the flowering stage makes the plant to grow more and not to set flower, and over watering the plant can cause flower to fall off also. So if you can take off the mini greenhouse would be better, if don´t make some way to ventilate it at least at day´s warmest period. Don´t water more than 0.7 glls/plant/day, water from 0.4 to 0.7 glls/plant/day depending on Tº and plant size and spread the amount during the day if you can. From now on fertilize with a formula high in potassium low in Nitrogen (3N-5P-8K) since the plan is at production stage.....also add some calcium if could.

Answer 3

I prefer growing them in the ground, but use grow bags too. They will grow fine like that.

I drench tomato plants with lots of water once a day when the flowers appear, using the rose on the watering can. It's supposed to help the flowers set.

Answer 4

Most likely reason for bud drop with toms is too great a variation in temperature at the time the flowers are setting. The smaller the greenhouse the bigger the problem . . . . . remove lower leaves to allow better ventilation and open door during hot periods. If using a convential greenhouse consider an automatic opening devise for the ventilation window(s) in the roof

Answer 5

Firstly, toms don't really like grow bags, they prefer big pots of soil. You need to nip out buds that will appear so you don't waste resources on leaves, and ditto keep the plant short during the end of the season (heading into it now). Mine (also a first time grower) are 6ft tall, and the nipping of the buds keeps it from bushing out. Good luck next year!

Answer 6

You didn't need a green house. With the plastic you may have cooked them and that is why your blooms fell of. I had two cherry tomato plants this year and they are still producing. I have enough to feed an Army.

Answer 7

It sounds like the fruit didn't set - in other words the flowers weren't pollinated. That isn't usually a problem, I think, since tomatoes will pollinate themselves.

It's rubbish that tomatoes don't like growbags - loads of people have very successful crops from just one or two in a small patio or yard.

Tomatoes do like sun and warmth (which we've had plenty of) and PLENTY of water. When the fruit starts to form, you begin to feed them but they shouldn't need Tomorite (or whatever) before that. If you kept your mini greenhouse closed all through the summer, it may just have been TOO hot for them.

Answer 8

Sounds like a pollinaton problem.
When the yellow flowers appear spray them with water - but not when the plant is in direct sunlight as this could scorch it.

Good Luck next year!

Answer 9

pollinaton for sure. It work otherwise. bees cant get in or butterflies. Need to open it up or u need to do it manually.

Answer 10

maybe you planted flowers not tomatoes
