🌱 Why am I HAPPY to find these knots on my roots? 🤔

Because these aren't root-knot nematode galls. They're nitrogen-fixing nodules! 🎉

Here's an easy way to tell the difference: Nitrogen nodules are attached to the roots and can usually be rubbed or popped off. Root-knot nematode galls, on the other hand, are swellings of the root tissue itself. They don't simply rub off.

These beneficial nodules house bacteria that convert atmospheric nitrogen into a form plants can use. It's one of the many reasons I love growing legumes as cover crops in my food forest!

🌿 And I have a new FAVORITE cover crop: MAVUNO COWPEAS!
I've grown plenty of cover crops, but these Mavuno cowpeas have absolutely blown me away with the massive amount of biomass they produce and their impressively THICK vines! 👀

Even better, they spread across the ground like a living mulch, helping shade the soil, suppress weeds, and build organic matter. Unlike many vigorous cover crop vines, Mavuno typically doesn't climb neighboring plants, making it especially useful between young fruit trees.

When I terminate these vines, I'm returning all that wonderful organic material to the soil. Chop, drop, and let the soil food web do its thing!

💜 And then there are my VELVET BEANS!

These haven't produced nearly as much biomass as the Mavuno cowpeas in my food forest, but they're fascinating! Their beautiful purple flowers and fuzzy, dark velvet-covered pods are worth growing just to admire.

But there's another reason I'm excited about them: Velvet bean (Mucuna pruriens) has been studied for its ability to suppress root-knot nematode populations. That's a particularly welcome benefit when you're working to build healthy, biologically active soil!

Different cover crops bring different benefits, and I'm enjoying discovering what works best in my developing food forest.

A big THANK YOU to my friend Dan Sobien who shared the seeds for both my Mavuno cowpeas and velvet beans! 🌱💚 I'm having so much fun experimenting with these two cover crops and seeing what each brings to my developing food forest.

After 9 years of battling root-knot nematodes, what FINALLY worked?

Join me for the YouTube Premiere of my interview with Anni Ellis on WMNF 88.5 FM's Sustainable Living Show! We're talking soil solarization, regenerative gardening, and why working WITH nature changed everything.

💚 I'll be in the live chat, so come say hello!

A weird software glitch turned into something I never expected. 🌱
My payment went through, but my order didn't. What Josh Jamison of Cody Cove Farm & Nursery did next says a lot about the person behind the plants and ultimately led to a conversation that changed how I'm approaching my food forest.
Sometimes the best stories start with something going wrong.

October is the month for most Florida gardeners to make the full transition to cool-season crops. Now is the ideal time to plant beets, broccoli, cabbage, carrots, cauliflower, celery, Chinese cabbage, chives, collards, fennel, kale, kohlrabi, lettuce, mizuna, mustard, onions, parsley, English peas, radish, spinach, strawberry, turnips and any other cultivars of Brassica. If you want to grow garlic, soft-neck varieties need to be in the refrigerator now, and planted out in December for the best production. Right now, seeds or transplants are fine to put in the ground for any of the cool-season annuals. Most of Florida is entering the dry season this month, so plan to water new plantings regularly until they get established.

In the South Florida growing zone, you still have time to put in transplants of peppers, tomatoes and eggplant, and to seed snap beans, corn, cucumbers, Seminole pumpkins and summer squash in addition to the above items.

For the whole southern half of the state (where no hard freeze is expected), perennial vegetables that can be planted any time include achira, aibika, cassava, chaya, katuk, longevity spinach, moringa, Okinawa spinach, and tindora. In North Florida, most of these will require some winter protection.

The roselle harvest keeps coming! ❤️🌺

With eight plants producing, I’m harvesting another batch of these thick, fleshy calyces every couple of days, and I’m definitely not complaining. 😋

Most of this harvest is going straight into the freezer. I’m saving up enough to make my own roselle “cranberry” sauce for Thanksgiving this year, and I’m really looking forward to seeing how it compares to the traditional stuff.

I also want to use some for tea, but with this much roselle coming in, I’m ready to experiment!

If you grow roselle, what else should I make with it? Recipes and ideas welcome! 👇

🍄 Are mushrooms in your garden good or bad?
This is one of the most common questions I see from new gardeners. Mushrooms suddenly pop up in a garden bed or lawn, and the first reaction is often: What are they, and how do I get rid of them?

I've been finding these little guys repeatedly in parts of the yard that will eventually become our food forest here in Sebring. And rather than seeing them as something I need to eliminate, I'm pretty happy to see them.

The mushrooms we see above ground are only the fruiting bodies of fungi living below the surface. In many cases, their appearance is associated with moisture, organic matter, and fungi doing exactly what we want them doing: helping break down dead plant material and cycling nutrients back through the soil.

I wrote about this in “Mushrooms in Your Garden: A Sign of Healthy Soil & Natural Enrichment,” where I get into what's happening beneath the surface and why these temporary little visitors can actually tell us something interesting about our soil.
If you're a newer gardener who's ever wondered, “Are these mushrooms good or bad?” this one's for you. 🍄🌱

I'm honored to have been asked to speak at The Garden Club of Sebring on Monday, September 28th! 🌱

I'll be talking about soil health and root-knot nematodes, including some of what I've learned in my own garden about building healthier, more resilient soil rather than simply trying to kill what's living in it.

And as a relatively new Sebring resident, I'm especially excited about meeting even more local gardeners, reconnecting with some familiar faces, and sharing what I've learned along the way.

So if you're in the area, I'd love to see you there!
