Citrus & Fruit Trees
Complete nutrition for citrus, avocado, stone fruit, and orchard trees — from the balanced seasonal feeding that drives fruit production to the micronutrient corrections trees signal through their leaves.

Palms & Tropicals
Purpose-built nutrition for palms, bananas, birds of paradise, and tropical ornamentals — indoors and out.

All-Purpose Houseplant Food 21-7-14 delivers the classic 3-1-2 foliage ratio at measured indoor strength, while Chelated Iron corrects the pale, yellowing leaves common in indoor citrus and acid-loving houseplan...
