Many varieties of this subtropical vegetable exist, from the small, pop-in-your-mouth cherry tomato to the enormous beefsteak varieties that weigh in at over 1 lb. each. Whichever type you grow, tomatoes benefit from some basic plant nutrients such as phosphorus, nitrogen and potassium.
Sometimes, excess nitrogen can be leached from the root area of tomato plants by repeated, deep waterings. Common causes of yellow leaves on tomatoes include cool soil, age-related death of the lower leaves and a myriad of nutritional deficiencies including nitrogen, boron, potassium, iron and magnesium.
