My tomatoes are in a container in the back garden, plenty of sun. The bottom leaves are turning yellow not sure why. Also I want them to stop growing and focus on growing the tiny toms already on the plant. Do I nip out the tops to stop them growing any taller?
It would be a shame to nip the tops out this early in the season - they'll carry on producing tomatoes for months yet.
The bottom leaves often go yellow - take them off - it will increase the airflow through the plant and help guard against disease.
Now that you've got some tomatoes on your plant, if you haven't fed with tomato food you should give them a dose of that and then I'd give them another feed in two or three weeks time and again two or three weeks after that.
They should carry on fruiting through at least until the end of September, probably longer if we get a good autumn, so don't go nipping the tops out yet!
Thank you for this, I suppose I just assumed nipping the tops was the right thing to do, I will leave them well alone. I have given them a feed so fingers crossed for a decent crop
