This is my first spring with a garden, and it's been going pretty great so far. I planted four tomato plants the first week of February and two about 3 weeks later. So far, five of the six have set tons of fruit and are looking just fabulous. The last one seems to be the runt of the litter. It was one of the last two I planted and it just hasn't gotten very big - a few blooms this week, but I don't see anything setting. It has a few lightly spotted leaves at the base and I'm thinking of just pulling it up. What would you do? I'm a little worried that if it's stressed it will be more susceptible to disease and get all my healthy plants sick too. It's an Heirloom Pineapple, if that makes a difference. I'm particularly fond of those, but willing to make the sacrifice for my others...
