Tomato Fertilizer 4-18-38 is a premium, 100% water-soluble fertilizer formulated for the flowering-through-harvest window of fruiting nightshade crops. The low-nitrogen, high-phosphate, very-high-potassium ratio is tuned to fruit development rather than leafy growth, with EDTA-chelated iron, manganese, zinc, and copper plus boron and molybdenum in every bag.

Potassium supports fruit sizing, sugar transport, firmness, and post-harvest quality, while available phosphate supports flowering and fruit set and the controlled 4% nitrogen keeps energy directed toward fruit. It is well suited to tomatoes, peppers, eggplants, tomatillos, and other fruiting nightshades, and dissolves cleanly for soil, container, drip fertigation, hydroponic, and foliar use.

This formula does not contain calcium by design — calcium and phosphate should not be combined in concentrated stock solution, so a separate calcium source should be applied independently for a complete program. Pre-dissolve each fertilizer separately, check pH and EC, and for foliar use, spray in early morning or late afternoon below 85°F. Store sealed and dry.

CDFA registered and third-party lab tested for heavy metals, with results consistently well below required limits.

Will not buy again
Size: 80P, Color: colored
We received the balls 5 days ago and so far our dog has destroyed a ball per day. At this rate, all the balls will be destroyed in 80 days. Not a good value for this product. We have other brand tennis balls that our dog has chewed on for months that have held up. We will not buy again.

good for light chewers
Size: 16P, Color: yellow
Decent number of balls for the price! Unfortunately, my dog obliterated half of the tennis balls within an hour, but I'm sure part of that is because he likes to carry more than one ball at a time and chew on them a little before dropping for someone to throw. Otherwise, they are super bright, making them easy to see in the dark or dark places. They have some bounce to them, which makes playing fetch a little more exciting. My dog loves balls, so he has no complaints other than they don't squeak.

Great quality and folding it in half is a plus. Fits under a seat in car/truck.
Purchased another, as we need one in each car. This is a great ball thrower, especially as it folds in a half. Makes it easy to store under a car/truck seat. Haven’t had any problem with it, great quality!
