Backyard biocontrol – using natural enemies to wipe out invasive weeds

The agricultural-residential interface

Four years ago we moved to the family farm (where I grew up) and we’ve enjoyed restoring the 1 acre landscape around the farmhouse. Given that the residential part of this farm is surrounded by pastureland, there is a continual influx of weed seeds into our managed beds. While our thick applications of arborist wood chips have kept out many weeds, they still pop up where mulch hasn’t been applied yet or is too thin.… Continue reading this article “Backyard biocontrol – using natural enemies to wipe out invasive weeds”

Diagnosing Abiotic Disorders I

Abiotic factors cause harm to plants resulting in symptoms. Abiotic disorders can look like damage caused by pests but do not spread in the same ways since the disease agent is not alive.

Insects and pathogens cause damage and disease in garden plants, but damage can also occur in absence of pests. We refer to these diseases as abiotic disorders. Plant pathologists consider abiotic disorders diseases because plants develop symptoms that reflect the changes in their physiology over time.… Continue reading this article “Diagnosing Abiotic Disorders I”

“PoP” Goes the Weasel

How do you plan your work in your garden? One of the things that is most likely to affect what you do is rainfall. But how do you know when and how much rain is likely to fall? One way to get an idea of the possibility of rain is to look at something called “Probability of Precipitation”, or as we call it, “PoP”. How often have you heard someone say that the weatherman (or woman) was wrong because they predicted 30 percent chance of rain and they did not get anything?… Continue reading this article ““PoP” Goes the Weasel”

Mycorrhizae: “If you build it, they will come”

“Field of Dreams”

The movie “Field of Dreams” is a family favorite – we love how baseball and the supernatural are interwoven to create a great story. If you haven’t seen the movie, you should – and for those of you that have, you know why it was important for Ray to build the baseball field. Like the magic that unfolded once that physical space was provided, botanical magic emerges from garden soils that support mycorrhizal life.… Continue reading this article “Mycorrhizae: “If you build it, they will come””

Catch my Drift? Herbicide Drift, Curling Tomato Leaves, and Food Safety

There’s all kinds of maladies that can strike your garden plants throughout the season- diseases, insects, negligence, and more.  But one common issue we are seeing more and more here in the corn belt and other places with lots of crop production is herbicide drift.  Of course, you don’t have to have a corn or soy field nearby to have issues with drift – it can happen anywhere and anytime an herbicide is applied and proper precautions aren’t taken, even when you or a neighbor are just treating a small area in the yard. … Continue reading this article “Catch my Drift? Herbicide Drift, Curling Tomato Leaves, and Food Safety”

Is your landscape “Sustainable”?

The word “sustainable” gained new life over the last few decades as the concepts of sustainable agriculture and now sustainable landscapes were developed. But what actually are “sustainable” landscapes? This is not something that is easily defined, so I offer my own ideas on the subject here. We can think about this and be thoughtful about landscapes and garden choices as we grow, plant, and maintain landscapes at home and in public spaces.

While this landscape has some of the elements of a sustainable landscape, it is very ugly, with tired artificial turfgrass.

“Water, water, everywhere…

Did it rain enough last night to water your garden? Have you started running the sprinklers and aren’t sure if they’re running enough? Perhaps you’re not sure that new drip system you installed is doing its job. Or maybe you just want to be more efficient and careful with your water use. How can you know moisture is getting deep enough into the soil to benefit your plants. Is there an easy way to find out?… Continue reading this article ““Water, water, everywhere…”

When normal isn’t normal

You may have read in the news earlier in May that NOAA has updated their “normals” for temperature and precipitation at stations around the country. In climatology, normals are the calculated averages over a specified time period. Usually, we use a 30-year period to capture what the average weather is like in a time period that is about the length of a generation, but now NOAA is also calculating normals based on other time periods like 15 years.… Continue reading this article “When normal isn’t normal”

Rooting around – the differences between taproots and mature roots

A seedling with green cotyledons and emerging radical

Most of us have witnessed dicot seed germination at some point in our lives – watching the coytledons transform from seed halves to green, photosynthetic structures, while the radicle developed into the seedling root system. This seedling root – or taproot – is important to seedling survival as it buries itself in the soil to provide structural support and to give rise to fine roots for water and nutrient absorption.… Continue reading this article “Rooting around – the differences between taproots and mature roots”

Contain Yourself: Vegetable gardening in containers and small spaces

Given the growing (haha) popularity of vegetable gardening over the last several years, which has gone into overdrive during the pandemic, more and more people are looking for innovative ways to grow in all kinds of spaces. Container vegetable gardening can be as simple as popping a tomato into a bucket, but there are lots of different ways to successfully grow crops in small, mobile containers. It is possible to grow full sized crops in containers, given a large enough container and space to grow.… Continue reading this article “Contain Yourself: Vegetable gardening in containers and small spaces”
