I want to grow tomatoes indoors during the winter. How many hours should I have the lights on and how many off to produce the tomatoes? I am growing Roma Tomatoes specifically. Please and thank you!
Hi! I'm growing some Roma tomatoes in a container (first time!) and the plants have recently started developing some spots on the lower leaves. I can not tell what it is, even with the many articles, they all look so similar! I would like to know if you can help me figure it out so that I can hopefully stop this from getting worse!
This looks like Septoria leaf spot.
Remove the leaves and dispose of them to avoid spreading this fungus.

I’m growing a Roma tomato plant In a planter box, and when it appears ripe, I pick it only to find a big brown circle/spot on the bottom of the tomato? I don’t know why I can’t get my photo to download?
That is blossom end rot. It is common with soils lacking in calcium, or with an unbalanced calcium and magnesium ratio.
I recommend Dolomitic lime for a long term fix, but if you want short term relief then epsom salt foliar spray will be preferable.

Yes, very mush so, thank you.
We are growing Roma tomatoes, but when we pick them they have little taste and are mushy inside. What do I do about this? Also it seems that our plants may have the blight, as the stems are turning yellow and falling off. any help would be appreciated. Thanks. Larry
Unfortunately, your photo did not come through. Make sure to test your soil for nutrient deficiencies and pH swings, first. This will give you an indication of what, if anything, your soil lacks.
Blight will usually show form as black or brown, circular, patches. Typically, this will be on older leaves, first, but can be throughout the whole. plant.

The inside of my Roma tomatoes are very bumpy. The tomatoes smell good and look fully ripe but do no taste good
This is, very likely, a sulfur deficiency. I would make sure to test your soil, and amend with the necessary amendments.

My Roma tomato is over 6ft tall and has 105 or more tomatoes on it. Is that normal? I did not plant it; a bird dropped it and God has taken care of it. I have not done anything to it but kiss and talk to it can we still eat them?
Since you didn't plant it, I would make sure 100 percent that it is a Roma tomato before eating it. Contact your cooperative extension agent closest to you for advice.

I have a determinate Roma tomato plant that I started from seed about 3 months ago. And it has about 15 tomatoes on it now and 8 of them are pretty large. However I was wondering if they would ripen, as it has been 31 days since the 8 large fruit have started growing on the plant. The daytime temps are 87°to 93° And night temps 75° to 78°. Since the night temp is in the ideal range for ripening, will they ripen even though the day temps are high? If not how would I go about turning these tomatoes red as they are full size but have no pigment at all (fully green). -Thank you
The heat will be the reason for lack of ripening, likely. This can be mitigated, slightly, by using a shade cloth for the hottest portions of the day. it will not solve the issue if ambient temperatures are that high, outside of the direct sunlight.
Unfortunately, you may be at the mercy of the elements, here.
What you can do, is pull them off and let them ripen indoors. This is common when they won't ripen on the plant.
