Q. I have had a hummingbird vine for roughly five years, and it has yet to flower. It vines all over my front porch. I trim it down, thinking it will flower. I have called the company I got it from, and they tell me nothing. I have been thinking of cutting it down and digging it up, but I want this vine to flower. Anything you can tell me will be greatly appreciated. A. […]
Q. Some years ago, I had a list of plants in the garden that were compatible and those that weren’t. If you have such information, could you include it in your “question and answer” column? It’s too late for this season, but we’d have it for next. A. The principles of “companion planting” are based on the belief that certain plants can benefit others when planted in combination or nearby. Such strategies can include using […]
Q. I have a lilac bush that I started from a “slip” from my sister several years ago that has never bloomed. It is growing leaves and is beautiful, but no blooms. What do I need to do? A. There are a number of reasons why a plant might fail to bloom. The most common factors are plant age, sunlight, plant nutrition, winter temperatures and improper pruning. You didn’t indicate how many years ago you […]
Q. I have two hydrangeas. One is a small bush (Annabelle) about 6 years old. It is on the south side of the house but is in deep shade in summer due to large trees growing south and east of it. The other is a climbing hydrangea on the east side and is in the sun in the morning. The climber grows luxuriantly. The bush isn’t really that happy. Neither has ever bloomed. I have […]
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. Although many seed catalogs may offer seed packets, the best spearmint selections are of Mentha x piperita and can only […]
Q. I purchased many unusual gourds from a local vegetable stand. How is the best way to dry them? How do I save the seeds for next year? A. First, let me address the issue that, due to potential cross-pollination with other compatible plants, saving seed from gourds is rather unpredictable. The offspring may include some plants that will produce similar to the parent gourd, but, then again, you can get some really diverse results! […]
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 […]
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 […]
Q. I have attached a tree photo that no one seems to know what it is. It has the berries at the top, and branches with leaves, and I did not notice until the leaves fell off that it had thorns on it. It does not have the berries on it until it gets big or old. I have 2 more small ones, but did not notice berries on them. A. This large shrub or small […]
Q. I would like to cover several parts of my yard with shredded bark mulch. My concern is we have some wood roaches in this area, and I do not want to attract them to my yard. We have had some in the house in the past and still get one or two occasionally. This is not a problem, but I’m afraid if we put down mulch this may be a big problem. What are your thoughts […]
