As anyone who follows us or shops at our nursery knows, we’re sold on Jack’s Classic water-soluble fertilizer for making your annuals and hanging baskets thrive. And a lot of our customers have taken our advice, with spectacular results. In fact, we’ve never yet met a customer who was disappointed in Jack’s and switched back to what they used before. Now, here’s a quick quiz: what’s the best type of Jack’s to feed your pansies?

For your outdoor gardening needs, Jack’s Classic comes in three main blends: All Purpose, Blossom Booster and Petunia Feed. Each serves a slightly different purpose, and all are excellent blends. For your pansies, though, one blend in particular will keep your plants lush, well-branched and blooming consistently. So which blend is best for pansies? Need a hint? It’s the fertilizer with extra iron.

Okay, time’s up. Which Jack’s is best for pansies? Petunia Feed. Like petunias, pansies require extra iron to keep their best form and color, and Petunia Feed fills just that need. While All Purpose and Blossom Booster are our go-to fertilizers for most of our other summer flowers, Petunia Feed is all we give our winter and spring pansies, and they love it. So next time you’re ready to feed your pansies, pull that tub of Jack’s Petunia Feed off the shelf–or stop by the nursery to pick one up if you’re all out–and see how your pansies thank you!
