My primary vegetable bed has a Rootknot Nematode problem. They destroyed my fall harvest of tomatoes and peppers by attacking the plants’ roots.
Thanks to some stellar advice online, I will not be solarizing the soil to kill them, along all the beneficial organisms. Instead, I’m going to displace them using helpful plants (hopefully).
Here’s the plan:
1. No tomatoes or peppers in this bed this year. That’s what they attacked with vengeance in the fall and I am removing their favorite food supply.
2. I’m planting lots of leafy greens, especially Broadleaf Mustard. They are high in oxalic acid which harms nematode eggs and suppresses the population.
3. I’m adding Broccoli,Cauliflower, and Red Acre Cabbage. Something chemical in brassica plants has a toxic effect on nematodes. Admittedly I don’t fully understand the mechanism but I’ll give it a shot.
4. Marigolds finish the trap. Marigolds attract nematodes, which enter the roots but then get trapped. They can’t grow or escape, and the marigolds will eventually kill them.
Cool temps and soft breezes. I am thrilled November has arrived.
And, there’s more! I came home from a business trip to find this giant pile of mulch in my driveway.
Chip Drop came through for me. If you are unfamiliar with Chip Drop, this is a sustainable service worth learning about.
To add the recommended 3-4″ of mulch over my giant perennial bed, and my annual vegetable garden, and my large potted trees and bananas, I require bags upon bags of mulch. So many good trees demolished. So much plastic. So much cash.
As an alternative, Chip Drop connects with local tree services companies in the area. When someone in your neighborhood has a tree cut down, the tree service mulches it and drop it in your driveway or yard or wherever you specify. This is my second delivery.
The first time, I received a fresh pine tree and my yard smelled of Christmas for weeks. This one is a finer, cleaner mulch. And they provided enough for me to mulch everything in my backyard as well as start the other landscaping projects I’ve been planning all year.
Technically, the Chip Drop service is free. But there are so many sustainably-minded homeowners in my area that waiting for a free drop can take over a year. I upped my bid from $0 to $20, and voila, a vehicle-sized mound of mulch appeared three weeks later.
I am anxious to get started. Before and after pictures to come.
And perhaps now is the time to buy the wheelbarrow I’ve been coveting. I always appreciate a clever yet simple product design, and this would cut my bending, twisting, and lifting in half.
I am loving the new monthly seed swap at Shell’s in Tampa. Today, I donated a tray of Cranberry Hibiscus and succulents. In return, I left with a new infusion of natives, edibles, and pollinator-favorites.
Here’s a sampling:
More on each of these new additions to come. But the weather is glorious and I’m headed outside to enjoy it.
Rains pummeled Tampa for the last few months. I left town and my garden at the end of April. Knowing I would not be able to do any yard work through May and June, with the exception of a few visits just long enough to collect a harvest, I experimented with three weed control strategies.
I mulched one bed with a free pine mulch that a tree service company dumped in my driveway.
A second bed I interspersed Boniato Potato seedlings wherever there was a gap of a foot or more.
The third bed is the largest, and has historically had the worst weed problems, so I did both: Boniato Potato seedlings plus pine mulch.
When I returned over two months later, the yard was a bit of a mess. But it was clear which strategy was most successful.
Here is the raised bed with pine mulch only.
What do you mean you can’t find the bed? See that tiny bit of cedar poking out? 🙂
Consider this method a massive failure.
Now take a look at the raised bed with Boniato Potatoes only. I ran out of mulch, so this was clean soil from the compost pile plus potatoes. Some weeds still worked their way through, but this bed is in far better condition.
When I started poking around, I was happily surprised at what I found. The potatoes did not choke out my plants, but filled in around them.
Here is a tall basil plant that would have been strangled in the mulch-only bed. The potatoes blocked the weeds around the basil without killing the herb. And those few tomatoes are attached to an Everglade Tomato vine that runs underneath the potato leaves. Also hiding among the potatoes: Yellow Pear tomatoes, Okinawa Spinach, and Pineapples. A few plants that started in this bed have disappeared: kale, a mesclun salad mix, and more greens that don’t typically fare well this late into the summer.
Some weeds still managed to weasel through the dense canopy of potato lives, but compared to the other bed, this method was far more successful.
And here is the largest garden bed. It is lowest to the ground, only raised by about 4″, and already had a weed infestation. I pulled out everything I could in April, but expected a number of returning invaders. In this bed, I mulched, I planted potatoes, I added moss from the tree in the front yard. I did what I could.
The result is better than I expected. A lot of weeds, yes, but the plants I care about are protected enough. My Rosemary bush is healthy. The Cranberry Hibiscus I thought I lost in the freeze came back, along with at least ten volunteers. False Bird of Paradise, also heavily damaged by January’s freeze, are back.
It took a couple hours to excavate, but the plants I care about are all here, protected by the potatoes and mulch. I harvested a bowl of Sweet Italian Red Peppers, Hungarian Hot Peppers, and Chili Peppers. I clipped handfuls of Basil, Mint, Papalo, and Cuban Oregano. I yanked the tomatoes that were at the end of life. The Prickly Pear Cactus, Aloe, and other succulents in pots throughout the bed are not thriving, but are also not dying. They are just waiting around for some love and attention. Florida Lettuce, Okinawa Spinach, Sticks on Fire, False Roselle, Lillies, Lemongrass…they are all doing well, hiding among the potatoes.
I’m looking forward to eventually harvesting the sweet potatoes, a secondary reward for this self-caring weed control. Overall, I’ll call the method a success.
