Sunday, October 19: ā€œKnow Your Plantsā€ Workshop

With several other volunteers, I’ll be running a plant identification workshop at the Maple Street Community Garden in the Prospect-Lefferts Gardens neighborhood of Brooklyn. Details below.

Title: Know Your Plants!
Date: Sunday, October 19th
Time: Noon-2pm
Rain Date(s): TBD
Location: Maple Street Community Garden, 237 Maple St, Brooklyn, NY 11225

Join the NYC Pollinator Working Group and Maple Street Community Garden for a fun and educational workshop where you’ll learn how to identify plants using field guides, keys, and the iNaturalist app. Get creative with a plant-themed arts activity, discover simple ways to record and track the plants in your garden, and explore an information table all about native plants, pollinators, and how to support them. Perfect for budding botanists and nature lovers of all ages!

The New York City Pollinator Working Group (NYCPWG) networks and collaborates to conserve beneficial pollinating insects and the resources they need to survive. Our members work on a variety of projects that support pollinator habitat in public and private spaces, provide educational outreach on pollinator protection, and develop advocacy programs and policies around pollinator conservation. Our goal is to be a model for creating pollinator sustainability in urban environments. As a project of the Open Space Institute, Inc., donations to NYCPWG are tax-deductible. Visit us at nycpollinators.org and @nycpollinators.

The Maple Street Community Garden is a multipurpose garden and community space located in the Prospect Lefferts Gardens neighborhood of Brooklyn, established in 2012 by residents of the neighborhood. The mission of the Maple Street Community Garden is to foster community and cultivate a peaceful and joyous place to serve everyone. We are dedicated to providing a safe and brave space for community members to gather, regardless of their race, age, religion, educational background, class, sexuality, gender identity, immigration status, disability and access needs, or any other marginalized status. Discriminatory language and behavior is not acceptable. As a community, we will hold each other accountable. Visit us at maplestreetcommunitygarden.org and @maple_street_community_garden.

Our open access paper just came out in #NeoBiota.

Biosecurity risks from weed seeds in crop seed imported into Canada: prevalence, trends and herbicide resistance.

Lead author Jesse Rubenstein's efforts brought Lincoln University, SIRC and AgResearch scientists together to examine Canadian seed inspection data. He led similar work for NZ, which was published earlier.

šŸ”— DOI link: doi.org/10.3897/neobiota.103.1

Overview: We analysed twelve years (2007–2019) of Canadian Food Inspection Agency monitoring data for more than 2,000 randomly sampled seed lots imported from the United States. Of the hundreds of contaminant species recorded, 70% were introduced in Canada, 23% were native, and 7% were previously unrecorded (absent) in Canada. Contaminants with a known history of herbicide resistance in the USA but not in Canada increased significantly over time (e.g., Sorghum halepense, Poa annua). Noxious weeds declined across the study period and were reported significantly less frequently than non-noxious weeds, while entry-prohibited species were rare, limited to four records of Cuscuta spp. We identified 14 weed species absent from Canada, with Trifolium vesiculosum the most common, while Chenopodium album was the most widespread across crop species. Regulatory concerns include the import of crops also classified as noxious or problematic weeds (Bromus tectorum, Poa annua), permitting contaminants absent from Canada in seed lots, and the dual classification of species that are native but also entry-prohibited (Cuscuta campestris). Our study underscores the need for continued monitoring, risk assessment, and adaptive regulation to protect agriculture and biodiversity while accommodating global seed trade.

We’d be glad to hear your thoughts, and please do share with anyone who might find it interesting. #IAS #biosecurity #weeds #weedscience

Weeds! 🌿

After living in an apartment for ±6 years, where I had a tiny balcony, it was a big change to go to a little house with two (smaller) gardens. Unfortunately, the area where the houses have been built, used to be a huge green area full of grasses and weeds. And those remains are still strong in the grounds here, so getting the weeds out of the gardens, feels like a never ending battle. I know there are items that will help in the fight against the unwanted greens, but... They do require funds to buy them, and then the time and help to be able to place them. I have tried to get the weeds out so many times. And, before I knew it, they were back, sometimes with a vengeance! This area is so "soiled" with all the remains of the old weeds, that when you take out the weeds from the top, there is enough left of them below ground to come back quickly. Even when I tried to dig out as much as I could, it still didn't take too long before all my hard work disappeared as snow does before the sun... And this makes it very hard to keep going at it. (yes I know I could have maintained it, but you do need energy, decent weather, and a properly working body for that). […]

Google has just informed me that I can use a 20% solution of vinegar to kill cleavers. I am curious to see if it works, so I have made some up and sprayed it on a patch of the cleavers in my back yard. If this works, there's going to be vinegar everywhere!

A tiny Tropical Spiderwort sprung up amongst the beans today.

This plant is considered a weed but it has been used as famine food, anti-inflammatory drug, laxative and as a cure for leprosy in Pakistan and Nepal.

It is classified as a noxious weed in the US

ā€œThis is a dead honeybee. The pollen on her legs is from dandelions. Her tongue is sticking out due to what killed her that was on the dandelions.
It’s spring, dandelions are the bees first food. This bee is dead from weed killer spread on what we see as weeds, but what nature sees as food. Please don’t spray for weeds until you see the blackberries blooming. In this area, weeds, flowers and fruit trees are bees only source of food until middle of June. There are FAR more weeds than flowers or fruit trees, so it's their only food source. No bees, no food crops for us and we all starve.ā€#bee #pollination #garden #weedkiller #pesticide #environment #weeds #dandelion #death #spring #agriculture #farming #food #foodsecurity

Here's a new weed to watch out for in NZ: long-flowered Veldt grass, Ehrharta longiflora.

I found one in flower yesterday. It's an annual relative of the now widespread perennial Veldt grass, Ehrharta erecta, which the NZ Plant Conservation several years ago voted the worst environmental weed in NZ. That's because it chokes out semi-shaded areas in bush where a lot of native herbaceous plants like to grow.

Long-flowered Veldt grass may not be as bad, since it's a fast-growing Spring annual, but still, do we want to take that risk?

At the moment the *only place* in all of the South Island that it's known is around the base of Hackthorne Road in Christchurch. Some effort has been made to contain it but the main property that it's on doesn't want the council on her land so it keeps spreading here.

If you find it anywhere else, that's important. Note the distinctive pinkish bracts on the flowers.

A photo I took yesterday of long-flowered Veldt grass in flower. The flowers are long and thin and green with pink bracts.

For a full-res version of this, go to https://inaturalist.nz/observations/310728311A screenshot from iNaturalist of the current distribution of long-flowered Veldt grass in New Zealand. It's only at one small site in Christchurch city in the South Island and a small area in Whanganui in the North Island. This is how weeds get started.

Friends, don't let weeds grow over the tarps you laid out previously to suppress weeds 😭😭😭. These wedelia are no joke. There is a THICK mat of them over the old tarp.

Gardening’s Hidden Benefits: How Digging In The Dirt Could Bolster Mental Wellbeing

If you spend any time gardening, you probably understand what I mean when I say it feels good  despite the lifting, sweating and straining involved. Yes, exercise is good for our bodies, but there’s something about digging in the dirt while listening to a bird soundtrack that lifts my spirits. Even the scent of the soil and mulch makes me happy. As it turns out, there are scientific reasons for this……Continue reading….
