San Marzano tomato plants need support to handle the heavy fruit loads they produce. With their compact growing habits, they can quite easily gain support from a stake, cage or even a small trellis.

Liquid fertilizers take nutrients to the roots and foliage of the plant quickly. Fertilize a total of 3 or 4 times every 3 to 4 weeks. After that, stop fertilizing to allow the plant to concentrate its power on fruit production and ripening.

Too much fertilizer too late in the growing season will cause the plant to produce new foliage, and not more blooms.

As for watering, as with all tomatoes, plants should be receiving around one 1 inch of rainfall or watering per week. If mother nature isn’t providing it, plants should be watered accordingly.
