Pollinators are abuzz for the 2019 Perennial of the Year


By selecting Stachys officinalis ‘Hummelo’ as its 2019 Perennial Plant of the Year, the Perennial Plant Association once again continued its focus on pollinator-friendly plants. ‘Hummelo’ is a compact, clump-forming perennial, reaching 1.5 to 2 feet tall and wide. Over time, the plants will form a dense mat, spreading slowly from creeping underground stems. Showy magenta flower spikes rise well above the foliage in midsummer and are quite attractive to butterflies and other pollinators. Plants are hardy in […]


January Garden Calendar


Home (indoor plants and activities) Keep holiday poinsettias and other plants near a bright window. Water as top of soil becomes dry. Increase humidity around houseplants by grouping plants together, placing them on a pebble-water tray or running a humidifier. Check stored produce and tender flower bulbs and roots for rot, shriveling or excess moisture. Remove and discard damaged material. Repot houseplants as they outgrow current pots. Yard (lawns, woody ornamentals and fruits) Check young […]


Spice Up Your Holidays


Some of the most popular spices used this time of year are harvested from various parts of exotic tropical plants, lending a special flavor to holiday recipes. Ginger is harvested from the rhizomes (underground stems) of a tropical/sub-tropical herbaceous plant, Zingiber officinale. Ginger is native to tropical Asia and is grown commercially in Hawaii and many other countries, including China, India, Thailand and Brazil. The rhizomes are harvested after the first year of the plant’s […]


December Gardening Calendar


HOME (Indoor plants and activities) Check houseplant leaves for brown, dry edges, which indicates too little relative humidity in the house. Increase humidity by running a humidifier, grouping plants or using pebble trays. Extend the lives of holiday plants such as poinsettias and Christmas cactus by placing them in a cool, brightly lit area that is free from warm or cold drafts. Houseplants may not receive adequate light because days are short and gloomy. Move […]


Gardeners worn down; clearweed may be culprit


Q: I have had a garden on our property for about 14 years. Naturally, we’ve always had to deal with weeds, but until last year they had been the usual crabgrass and other types that could be controlled if you kept ahead of them. But last year, some type of weed or ground cover has sprung up, and it’s infuriating!! There is absolutely no way to weed it out by hand because it comes up almost […]

Time to Harvest Sweet Potatoes


  Although some folks may be sad to see summer coming to a close, many gardeners are looking forward to harvesting their sweet potato treasures. Sweet potatoes are warm-season plants that are very sensitive to cold temperatures. The tuberous roots should be harvested by the time frost kills the vines or soon thereafter. Sweet potato roots continue to grow until frost kills the vines. Roots can be left in the ground for a short while; […]


Oedema Is a Corky Quirk


Plants that experience extremes in soil moisture may develop spots on their leaves, called “oedema” (also spelled “edema”). The spots may first appear as a blister or raised spot, particularly on the undersides of leaves, but may occur on the top side as well as on the stems. Eventually, the blister develops a rust-colored, cork-like scab. Oedema is most commonly seen in the greenhouse on ivy-leaf geraniums but also on pansies, jade, and other thick-leaved […]


September Garden Calendar


HOME (Indoor plants and activities) Prepare storage areas for overwintering tender flower bulbs and garden produce. Thanksgiving (or Christmas) cactus can be forced into bloom for the holidays. Provide 15 hours of complete darkness each day — for instance, from 5 p.m. to 8 a.m., for approximately eight weeks. Keep temperature at about 60-65 degrees F. Temperatures of 55ºF will cause flower buds to set without dark treatment. Dig and repot herbs, or take cuttings, […]


Use Caution With Spreading Plants


People often select plants first for their beauty and second for their functionality in the garden. Frequently, we don’t know or don’t consider a plant’s behavior when we’re selecting them. Almost by definition, a species that is an effective ground cover will have a spreading habit. But does that make the species aggressive or invasive? There can be much confusion about the meaning of the terms aggressive and invasive. Some plants, given their optimal habitat, […]
