Q. I have some spearmint growing now. I can tell when I mow over it, but I don’t know what it looks like. I would like to grow more but don’t how to go about it. A. All of the culinary mints have square stems and opposite leaves, with spearmint, in particular, having elongated-ovate leaves with coarsely toothed margins.

First, let me address the issue that, due to potential cross-pollination with other compatible plants, saving seed from gourds is rather unpredictable.

Q. Could you please tell me what I can do for my concord grapes? When they start ripening, they rot, or something like that. A. I’d place my bets on a fungal disease called “black rot.” There are some grape cultivars that are resistant to grape rot, but, unfortunately, ‘ Concord ‘ is highly susceptible. According to Purdue Plant Pathology publication BP-36 “Grape Black Rot” http://www.ces.purdue.edu/extmedia/BP/BP-36.html , this is one of the most common and serious diseases […]

Terrariums

A terrarium is a delightful way to grow an indoor garden of small plants in an enclosed glass container. With proper care, a terrarium will create a humid atmosphere that protects tender, tropical plants that are difficult to grow in the normally dry atmosphere of our homes. The concept of a terrarium as we know it was discovered quite by accident by an English physician and botanist named Nathaniel Ward. He was trying to raise […]

Q. Concerning the question about deer and other wild animals eating plants, bushes, and young tree growth, etc.: We were told (and experienced) to tie (a particular brand of deodorant) soap to all trees and bushes to keep deer from eating our landscaping. It works for us. We have seen as many as 40 head in our area in Steuben County. They are here! And before, we tried everything. A. Your soapy landscape plants are […]

The long-lasting, blue-violet flowers contrast beautifully with the mounds of grey-green foliage. The plant […]
