I'm sure others will weigh in that know more than me, but I would be very cautious about fertilizing much yet if you transplanted them recently. I'd give the roots plenty of time to establish themselves first. If I did fertilize, I'd probably do a foliar spray (which is controversial with some) and only fertilize at half the rate or so.

Like any new transplant, you have to keep them watered.
And, fertilize with liquid fertilized at 1/3 to 1/4 normal recommended strength every time you water( Use watering can)

Hello NurseChristina,

You list your zone as 5, but where are you located? Knowing that would help us give you better advice.

Do your tomato plants have blossoms or fruit on them? I assume since you mentioned SFG (square foot gardening) that you are planting in a raised bed. Did you move them into another raised bed, directly into the ground or into containers?

As long as they are not in containers, I would suggest side dressing them with the TomatoTone. I suggest it because the nitrogen is lower, you want support for fruits and roots, not foliage growth. NPK = up, down, all around.

Just follow the TT's recommended amounts in a circular furrow about 6" from the stem. Keep the fert off the leaves and roots so they don't get burned. You can follow up with another feeding in 3-4 weeks.

If they are in the ground (or raised bed) I'll contradict Seysonn's watering advice . . . . Neither of us knows where you are or if you are container gardening, so we may both be wrong. However, I'd recommend deep watering if they are in a raised bed or in the ground, I don't think you'll get the deep watering with a watering can. And if you are side dressing, you don't need to feed every watering. If they are in containers, then Seysonn's directions are right on.

I hope that helps.

Betsy
