everos, don't be tempted to overfertilise them. If they're planted in good, healthy soil in the first place they just don't need much extra nutrition.
Once when the first fruit appears, then maybe a couple more times over the length of the growing season. Tom plants pumped full of nutrients are less likely to produce to their full potential than plants left to cope for themselves.
Toms, like most plants, exist to reproduce themselves - which, in the tom's case, means producing fruit. They'll be much more inclined to reproduce themselves if they feel ever so slightly threatened. Stuffed full of nutrients, they feel no real need. You'll get fruit, certainly, but less than the plant is capable of giving you.
