(Left to right) The October surprise, or should we say November surprise, of the ACG is the New England aster (Symphyotrichum novae-angliae). Do you still have pumpkins and gourds hanging around through Thanksgiving? Each year an estimated 1.3 billion pounds of pumpkins and gourds end up in landfills. Consider adding them to your compost or find a local participating municipality accepting them for donation.

How ‘bout that October? Except for precipitation of any sort, there was something for almost everyone—a little hot, a little cool, and some stereotypical October Piedmont North Carolina, NC State Fair weather. There haven’t been very many State Fairs in my memory without some honest to goodness rain. We’ve been blessed unless, of course, you were trying to grow plants which is sort of what we’re all about here. So, mixed blessings? I mean, as fantastic as this area is, it still ain’t Camelot, Guinevere.

The Accidental Cottage Garden (ACG) is too stubborn to give in to the crazy droughty up and down weather. There are some tough characters out there. The toughest of which must be the gallardia (G. pulchella). It doesn’t know quit. The African marigold (Tagetes erecta) and the zinnias (Z. elegans) are also heat and drought tolerant along with the false vervain (Glandularia bipinnatatifida). (Somebody stayed up late naming that one!)


A delightful surprise this year is a lovely New England aster (Symphotrichum novae-angliae). It isn’t as erect as I might be as it was crowded in amongst some other things, and I didn’t become aware of its existence until recently. Next year. Most of the hardy ageratum (Conoclinium coelestinum) have succumbed to the drought and the shorter days. There are a couple of late-to-the-party purple cone flowers (Echinacea purpurea) and a stray black-eyed Susan (Rudbeckia hirta). The muhly grass (Muhlenbergia capillaris) are looking a little thin and wispy, but I attribute that to it being the first year in the ground for them. Enough about my garden, let’s talk about what we can do in yours in November.

Lawn Care

Well, if your lawn has survived “No Moisture November” the main task for November is keeping it relatively leaf free. Whatever your remove from the lawn should be composted or used as mulch. The leaves do not belong in the landfill (or the ditch out front, for that matter). Cool season lawns (tall fescue, bluegrass, perennial rye) will still need mowing at the 3½” to 4” height.

The leaf admonishment pertains here, also. If you renovated/overseeded your lawn this fall it will need watering until the drought is done with us. 1” per week minimum applied in two ½” applications is necessary to keep it going.

Fertilizing

Not this month. If your (FREE until the end of November here in NC) SOIL TEST indicates a need to raise the pH, apply the appropriate the proper amount of lime and incorporate it into the soil if possible. Lime doesn’t readily move through the soil and incorporating the lime gets to the roots where it is needed.

Planting: Yes, “Fall is for Planting”

Trees, shrubs, and ground covers planted now will have all winter and early spring to put down roots in order to better withstand next year’s drought periods. (They’re coming. Trust me.) Spring flowering bulbs can still be planted until the end of the month. Year-old asparagus crowns can be transplanted now.

Pruning

So, for years (decades, centuries?) pruning all the perennials back as the blossoms faded (Grandma kept a tidy garden!) has been gardening gospel. Well, that good news is now obsolete news. It seems that solitary native bees and other pollinators lay their eggs on/in and/or nest in those stems for the winter. So, cutting them is detrimental to the pollinator population. Ergo, don’t do it anymore (unless the HOA is going to place a lien on your house for leaving them unpruned). (I don’t suppose the “It’s winter interest”, argument will get you anywhere.) Dead or diseased wood can be removed from trees and shrubs. Make any cuts at the branch collar (flared end) to promote healing of the wound.

Spraying

Any pests still hanging around can be treated with an application of a horticultural oil that will smother adults, eggs, and all phases in between.

Other Fun-filled and/or Fantastic Fall Frolics

Take a leaf hike through somebody’s neighborhood or a state or city park. There is a plethora of opportunities nearby.


Invite friends and neighbors over for an evening around the fire pit. S’mores, hot
chocolate, cider, and donuts are about mandatory. Anything else is optional.

Do anything else you can think of to get yourself outdoors to enjoy these last user-friendly days of 2024.

May you have Thanksgiving bountiful enough to share.

A Greener Plant Sale

If you’ve ever tried to reduce your carbon footprint, you know that it can take patience, persistence, creativity, and sometimes compromise. As the plant sale committee works to make our community a greener place with plants, we are also trying to keep our efforts green in the process.

As our Backyard Treasures Plant Sale name implies, much of our inventory has traditionally been sourced through generous donations from Master GardenerSM volunteer gardens. In recent years, however, we’ve grown to understand the risks of transferring unwanted species far and wide–not just invasive plants but also unintended species such as weeds and soil-dwelling creatures that may come along for the ride. The first way to combat this problem has been to increase the number of plants we start from seed.

Starting Plants from Seed

Our veggie and herb selections have always comprised almost a third of what we sell and are lovingly home-grown by a dedicated team of seed starters. In addition we now have a team growing a variety of native plants from seed. Many of these plants are challenging to start, their seeds often requiring complex temperature cycling to initiate germination. We also rely on our propagation team, another spin-off from the plant sale committee, for providing us with a variety of propagated plants. All of these plants, whether started from seed or propagated, are grown in clean potting mixes that reduce the spread of unintended species.

Growing Plants by Division

Many wonderful plants that we share are still sourced through the division of garden-grown favorites, and those plants are now thoroughly washed to remove all soil from the roots before they are potted up in fresh potting mix. While not perfect, this system can vastly decrease the chance of sharing undesirable plants and organisms.

Root washing to remove contaminants reveals the beautiful intricacies of the root systems.

Searching for the Right Potting Mix

Two years ago the committee began efforts to move away from peat-based potting mixes. Peatbogs, the source of peat for these mixes, are unique ecosystems and carbon sinks that are extremely slow to replenish. The committee had fun developing its own formula of a non-peat-based growing mix using coconut coir, perlite, vermiculite and compost. We tested the look and feel of various mixes to try to replicate the consistency of our traditional brand.

Scaling up proved to be challenging, time consuming and very dusty! There is a reason the best mixes are proprietary secrets, and indeed the seedlings in our concocted mix languished. For now we continue to start seeds in a peat-based mix for best results, while still searching for an economical and sustainable alternative. We have found an acceptable non-peat-based mix that we use for divisions and potting up seedlings once they are established.

From Plastic to CowPots®

This year, our focus has been on reducing our reliance on single-use plastics, specifically with respect to the pots we use. Most garden pots and flats are difficult to recycle because of the mix of plastics. Our approach to this problem will be twofold. First, we are trying to use a single pot size more consistently, namely what we call a quart pot. We are tagging plastic quart pots this year with a label that reads, “Return clean, intact quart pots to 721 Foster Street by May 31st.”

Our hope is that our local buyers will rinse and return the pots once they have planted their purchases. With a little extra care we should get at least one more season out of them and are excited to see what percentage of pots come back to us. In addition, we are spreading the word about how pots and flats can be recycled.

Second, we are piloting a biodegradable pot in our sale. After researching a variety of biodegradable options, we landed on CowPots®, a pressed pot made from dehydrated cow manure sourced from a dairy farm in Connecticut. The size is roughly equivalent to our plastic quart pots. They can be fragile to handle especially when wet, but the entire pot can and should be planted in the ground with the plant and should be completely degraded by the end of the growing season.

Plants grown in CowPots® are reported to have healthier root systems because of air pruning, a process that starts when the roots begin to grow through the sides of the pot. When the root tips meet air on the outside of the pot, it stimulates lateral growth from the root back inside the pot, as opposed to the circling of the root that occurs when it meets the side of a plastic pot. Additionally, the pot itself provides amendments and a small amount of nutrients to the garden soil as it slowly decomposes. These pots are only slightly more expensive than the plastic pots. It will be interesting to see how they are received by the public. Only a small percentage of plants this year will be grown in the CowPots, to give us a chance to evaluate them and address any problems that arise.

Adding these green initiatives to our plant sale practices has not necessarily made the work easier, less expensive, or even better in some cases. But it does feel like we are moving in the right direction to be responsible stewards of our land and to set an example for our community.
