General Conditions: Weather certainly is typical and spring like with the cool and warm temperatures, windy days and nights, and rainy or damp days. This pattern has continued throughout the month and into the last week of April. For this past week, a high temperature of 66°F was recorded on the 25th and a low of 31°F was recorded on the morning of the 28th, bringing with it a light frost that covered car windshields. Precipitation has been recorded for this area on six of the past seven days, bringing our total rainfall recorded for this month to 7.50”, which far exceeds the April monthly average of 4.16”! Lawns continue to green up and I saw my first mowing crew on Monday.

Pests/Problems: Acer platanoides (Norway Maple) is in full bloom. This invasive tree is hard to miss now that it is in bloom and its flowers are a bright yellowish-green and are easily seen on trees found growing most everywhere. Many herbaceous weeds are in flower including one of the most invasive of all time, Alliaria petiolata (garlic mustard). It’s just beginning to bloom, can easily be seen due to its white flowers and is growing everywhere including roadsides, woodlands, wetlands and gardens. Other weeds seen in bloom now are Glechoma hederacea (ground ivy), Lamium purpureum (purple dead nettle) and Taraxacum officinale (dandelion). Weeds emerging but not in bloom include: Arctium minus (lesser burdock), Impatiens capensis (touch-me-not) and Polygonum cuspidatum (Japanese knotweed). Be aware of Toxicodendron radicans (poison ivy). It is beginning to leaf out so it is fairly easy to detect its shiny red leaves of three.
