By David Wolfe – In an engaging Zoom presentation during the February 2021 HSCSS meeting, retired pro gardener Leo Chance recommended a list of cold-hardy cacti and succulents for growing outside in St. Louis. Several Gymnocalycium species, for example, are rather hardy, bloom consistently and …

By Bob Williams – There are two ways that cucumber beetles can damage plants. First are the larvae. They have a very hearty appetite and can devour the roots in a very short time.
