Do you love digging holes? Neither do we, but we sure love filling them in with a tree. Fall is the perfect time to plant! We have hundreds of fruit trees, native shrubs like elderberry and currant, even some grapes and all of them will be priced higher in the Spring. All remaining seeds from 2026 are 50% off! Worms, if we still have them are 50% off.

It's official, we're in a relationship with Shell. It's a little abusive sometimes but we feel like they really care about us.

It's TREE PLANTING time!! Fall is the BEST time to plant and we have lots of trees right now. Most of our trees have grown at least a foot or more since spring, while our prices haven't, meaning you will get more tree for your buck by not waiting for next Spring!! Check out our huge selection of Apple Trees.

There's still time for some serious pruning.

🥒 Cucumbers can turn into a tangled wall of vines surprisingly fast. Learning what to prune and what to leave alone makes them much easier to manage.

Ancient fertilizer ingredients, formulated for today’s growers 🦇 The Guano Company

Budswel by The Guano Company is a time-tested, award-winning blend crafted from three of nature’s most potent inputs: bat guano, seabird guano, and earthworm castings. This organic trio delivers a heavy dose of phosphorus to supercharge the flowering phase and drive explosive bud development in both soil and hydro setups.

Why guano? 🦇🐦 Because it’s rich in slow-release nutrients and microbial life that help plants uptake essential minerals more efficiently. The bat and seabird guano provide a concentrated source of phosphorus and potassium—key drivers of flower density, aroma, and resin production—while the earthworm castings boost microbial activity, soil structure, and overall root health.

The result? Bigger, denser blooms. Stronger, more vibrant plants. And better flavor, fragrance, and yield—without any synthetic additives.

Clean, organic, and proven. This is what feeding your plants with nature’s best really looks like! 🌺🍅

Retailers can pick some up from Hydrofarm via our website or by speaking to their local Hydrofarm rep 🤙
