Goldenrod Soldier Beetle: A late-summer friend in the garden

A number of ornamentals are in full bloom, ablaze with colors and, in some cases, buzzing with insects. One such insect that you may have noticed in your lawns is the goldenrod soldier beetle or Pennsylvania leatherwing (Chauliognathus pennsylvanicus).

Black and Yellow Garden Spiders

As gardeners harvest the last of their produce, many are noticing the black and yellow garden spider (Argiope aurantia) living among the vegetation. This spider may also be observed in crops, or tall grass or weeds that provide protection for their webs. These spiders (at least the females) stand out because of their bright colors, large size, and distinctive large web. While they are often overlooked, the garden spider is common throughout the United States.

Woody Weeds: Tatarian Honeysuckle

Tatarian honeysuckle (Lonicera tatarica) was brought to North America from Asia in the mid-18th century for ornamental uses. In South Dakota it was also used as a windbreak species until the 1980s.

Woody Weeds: Common Buckthorn

When considering weed control in tree plantings, the focus is generally placed on the control of herbaceous vegetation (grasses and forbs), particularly during the establishment phase. This focus is appropriate since control of herbaceous weeds is generally critical to establish a successful planting. As these plantings mature, providing perching sites for birds, another weed problem develops – the establishment of competing woody vegetation. These woody weeds are often left unchecked for many years because they look “natural” in a windbreak or other area of trees.

What's That Vine?

One of the most frequently asked questions that I have gotten recently refers to a vining plant that looks like it is going to take over the world, or at least a few trees in the yard or a section of a shelterbelt.

Smut is a fungal disease that can attack the leaves, stalks, tassels, silks and cobs. While many fungal diseases cause spots on the leaves or stems, smut is much more flamboyant.

What is This Fruit… And is it Edible?

In mid- to late-summer, we often get the questions: “What kind of fruit is this?” and “Is it edible?” To identify a fruit, it is helpful to know both plant and fruit characteristics: Woody or herbaceous plant? Vining or upright? Do the leaves attach to the stem opposite each other (i.e., paired), or do they alternate from one side of the stem to the other? What size and color are the fruit? Is each fruit’s stem attached directly to the twig, or are they in a cluster that attaches to the twig? And, one question I find often helpful in distinguishing among smaller fruits, does it have a single pit, or are there several seed in each fruit?

Growing Onions

Onions have been a commonly grown vegetable for thousands of years. They are easy to grow, nutritious and can be stored for months until they are needed as part of a meal. There are many different kinds of edible members of the Allium genus but bulbing onions are the most commonly grown.

What’s Bugging Your Garden: Picnic Beetles

One of the most common garden insect questions I get asked is “what are those little black, spotted beetles that are in my sweet corn, tomatoes, raspberries and perhaps worst of all, in your beer! These little nuisances are called picnic or sap beetles. They are attracted to ripe or damaged fruit and vegetables.

Community Gardens: Garden Rules - Operational Guidelines

When developing garden rules or participate guidelines it is important to address activities related to the operations of the garden. Clearly state that gardeners are expected to maintain their plot for the entire season and list the dates of the season during which they are responsible.
