I actually have similar question though I have a unheated greenhouse - whilst its 6 degrees outside today with strong winds where I am (south London), the sun is shinning and temperature inside greenhouse is showing 14 degrees Celsius.
I bought around 10 different varieties of perennial seeds last week in view of having sustainable flowering plants rather than buying loads of plug plants etc. to save money for years to come.
Most of the seed packets say sow them inside in March / April but on the other hand I've spotted plug plants of some of those same varieties being sold in local Garden center which makes me think if its OK to sow them in my greenhouse to enjoy early flowering etc. ?
Or is it too much hassle to grow them inside first and then plant them in borders etc. rather than sowing when its bit warmer directly in the beds?

FYI, I'm also growing some bush tomatoes next to the tall ones in another grow bag and they have now developed small fruits. So I gave them Tomorite yesterday :-) Pic as below.

You can hopefully now see the flowers and leaves. As you can see I had to open the top glass of greenhouse to avoid plants touching the roof and getting moist on top.
Would leaving it open like this cause harm via rain etc. ? It hasn't rained since I opened it a week back.
Also there are lots of flowers near the top and some more small ones growing. Please can you tell me things I should do now?

Can you see the latest picture I uploaded with my post before this one?

As mentioned already only remove some leaves when the (last) fruits are ripening or the bottom few in order to assist watering.
I think you might have a problem with hydration in a greenhouse using only a grow bag. If it helps, I use a drip feeder, any glass bottle with a couple of small holes punched through the lid this drips out over (approximately) 24 hours and should do a lot to prevent wilting and issues with inconsistent and insufficient watering.
Personally, I think you can get a lot more than 4 or 5 trusses from a tomato plant in a greenhouse without affecting the flavour. There's also a risk with such a small number as a few often drop off or don't develop, all that effort for 15 tomatoes? No thanks!
Height is usually your biggest enemy when it comes to creating your own tomato-plant jungle, pinch out the top shoots earlier than you think you should to and keep an eye on side shoots that you may have missed (I allow some of these to grow but they do rather exacerbate the 'jungling').
To answer your question, you should start to see flowers on them from around this time. I don't have fruit on many of my plants yet and around half are now flowering.See original post
Hello all. Thanks for your responses. Previous picture might have been a bit misleading so here is one showing top of the plants. As you can see I have opened the top glass of greenhouse. Would rain be bad for them? Should I now cut the top shoots and close the top? The plants have developed flowers near the top 20% part of them making the total flower bearing branches around 3-4 per plant. What time do the tomatoes harvest in greenhouses in south of England? I've now added bit more compost in the rings by the way.

Hello all. Growing for first time. I've 3 beefmaster and 3 bush tomato plants in small greenhouse, being grown in growbags.
As you can see the beefmaster have grown about 6 foot high and there are about 4 to 5 trusses with flowers in each plant. But they are mostly at 4 to 5 feet of height. What should I do to control their height please? Bending them to trail longer along the greenhouse might not be an option as I don't think there is enough space. Are they looking alright? I didn't know till late that suckers should be removed so each plant bas grown a couple of strong secondary stem that way. None of the flower has turned into small fruit yet and I'm in the UK. Is it all normal? Anything I should do to help them.
I'm just a little clueless, sorry. Happy to send more pictures if that helps. Thank you
