Get what everyone wants from their tomato plants - healthy vigorous growth and an abundant crop - with Jobes Fertilizer Spikes for Tomatoes. Convenient and easy to use, Jobes spikes provide nutrition underground at the roots, where plants can actually use it. Just insert spikes around the plants and the slow-release formula feeds your tomato plants for up to 8 weeks. Plus, spikes ensure that nutrients aren't washed away like surface-applied fertilizers. The specially formulated, pre-measured spikes deliver fast, easy and mess-free fertilizer. Our tomato spikes are available in a waterproof, resealable pouch or in a cardboard blister card pack.
