Posted by Hugh on July 19th, 2011
This South African native, also called ‘montbretia”, thrives in full sun in well-drained average garden soil. A richly composted soil tends to boost foliage size and bloom count, but often weakens bloom stems, requiring some staking. Crocosmia may struggle in a wet soggy wintry soil. Established plants are exceptionally summer heat and drought tolerant. Brightly colored […]

Chinese flametree (Koelreuteria bipinnata) is also called bougainvillea raintree. This rare tree, available primarily from internet nursery commerce, deserves to be planted more. It has performed well in the Southern Appalachian region (USDA zones 6-b and 7) and is questionably hardy further north. Flametree is less popular in Southeastern landscapes than goldenrain tree (K.paniculata). Low branching […]

Galinsoga grows only in cultivated soils such as in your vegetable and/or flower garden from part shade to full sun. It prefers moist soil but grows almost anywhere, even between cracks in a sidewalk. Its thin leaves may wilt […]

Posted by Hugh on May 29th, 2011
Mulching, in itself, does not attract termites to your home. That’s the conclusion of two university studies. Soil moisture appears to be the key factor that attracts termites to the home. The subterranean termites found in scattered, localized areas are routinely found in wood chip mulch. While landscape mulches are good for woody and herbaceous […]

Crippsii falsecypress (Chamaecyparis obtusa ‘Crippsii’) is one tall 20-25 foot high evergreen shrub (or small tree). Its lacy golden evergreen foliage catches your attention almost any season of the year. Unfortunately, Crippsii is rarely seen in landscapes because few landscape architects and designers know it or can not find it in the nursery trade. Ten years ago a credit union near my home […]
