Hi, it's my first time planting a single beefsteak tomato plant. It did beautifully all summer, grew huge with many fruits (about 30). The fruit blossomed and ripened very slowly and we've only picked about 4 to date. Now the plant is starting to die. I don't think it is blight, but maybe septoria (leaves are spotty, turn yellow then dry up). Since it's fall, not sure it will help to treat it with fungicide at this point. My question is there are still about 25 healthy green tomatos on the vines, some small, some large -- what should I do? Should I let them keep ripining until I see the individual vine turn yellow? Or, should I start picking them and let them ripen inside? If I leave them on the vine much longer, will I risk losing them all? Will try to post some pics later.
