Tomatoes not setting fruit

Recommended Posts

Do I need to do anything to help my greenhouse toms to fruit? They have loads of flowers, but some flowers have now started to wither and there does not appear to be any fruits underneath them.

I remember a friend used to mist them to encourage setting - I'll give this a go,but wondered what everyone else does (if anything!) :D

I had this for the first time this year, I've grown tomatoes for years and I've had plants die etc but I never recall a problem with setting fruit. I reckon it must be something to do with the weather?

 

I looked in the book and it said mist the plants, and also tap them occasionally (encourages the pollen to float about, I assume!) I did this and I have now got lots of little fruits, although there are still a few not setting.

I hose them with the sprinkler mode, but they are certainly not as good as last year. The bees get into our greenhouse and help pollinate, but still it seems very slow. I always keep flowers in the greenhouse anyway to help deter the pests and attract pollinating insects - so it must definitely be the weather's fault.

I got a paintbrush to try to fertilise my courgettes and have been using it on the tomatoes too, as I haven't seen any bees. There are lots of flies banging their heads on the roof of the greenhouse, but they don't seem to be landing on the flowers, so I thought I would help the tomatoes out. It seems to be working (although that may be wishful thinking).

Humming is optional! :lol:

Noooo, get the brush, wipe it in and around the inside of the flower and do the same on the next - just pollination the hard way. It's what they do when they want to make hybrids or new varieties, although they tend to put bags over the flower heads to stop any cross-pollination.

We have one tommy plant that hasn't any flowers until it gets near the roof of the greenhouse. Not impressed with that one.

I have been misting mine in the hot weather and I also leave both the door and the window open once June comes so that there is plenty of air and insect flow. One of my Tumblers has set so much fruit this year and still has many more flowers. That one is outdoors though.

I'll have to do some misting and pollinating with a paintbrush myself.

My greenhouse is full of tomato plants, lots of flowers on the 100 &1000s type, few other flowers and only 2 tiny tomatoes.

Meanwhile in the garden, a couple of tomato plants have sprung up of their own accord :roll:

They are already flowering, I'll bet they do better than the pampered ones in the greenhouse!

I wonder what variety they will be? I've also spotted a rogue chilli plant in the borders :!:

If you have a red bottle top - like on the milk - hang it among the lowest fruits - it's an old wives tale but it seems to kick start the others. I have no idea whether there is anything scientific there, but my folks always did it with theirs (it was probably a coincidence). Or a ripe banana put nearby will kick start them too.
