February Plant of The Month Galanthus nivalis (Snowdrop) Suggested planting rate: ten bulbs per 1 / ft sq. Planting Location: Sun - partial shade Height: 4-6" Blooms: February Bulb size: 6+ cm bulbs USDA zone: 4-6 Notes: Small, white pendulous blooms with long, slender petals that drape delicately over the perianth. Blooms early like crocus and is very hardy. Excellent for naturalizing under trees and in the grass, as they multiply rapidly once established and like moist, almost heavy soil.
Time To Control Fruit Diseases Winter believe it or not is a good time to prepare fruiting crops for the season ahead. It has been too cold for most of the winter for many of us to feel like braving the outdoors to any activities that aren’t absolutely essential, but on the next warm day it is very important for us to get some work done to insure a nice fruity harvest this summer. Many fruit diseases can be partially controlled by being vigilant with cleanup and fungicidal sprays at proper times. Also, remember pruning should take place in late February on fruiting trees. Below is a list of fruit crops along with diseases of concern and some things to do to help you have a successful harvest.

If sprays, such as captan, are to be used to prevent fruit rot, the sprays need to be applied to the strawberry flowers in early spring. Blueberries- The diseases of most concern will be twig blights and cankers. Prevent twig canker diseases by avoiding stressful growing conditions. Mulch blueberries with organic matter, such as wood chips, and adjust the soil pH if necessary to provide favorable growing conditions. Prune out dead and dying twigs and branches from the blueberry plants. If, because of wet weather, blueberries are declining and dying due to root rot disease, improve garden soil drainage or grow blueberries on raised beds.

Earthworms Can Cause A Rough Lawn Earthworms, particularly night crawlers, can be abundant in moist soils that contain moderate, or greater, amounts of organic matter. Worms take in and process soil and organic matter, then deposit the remnants (castings) during nocturnal surface visits. The castings dry into crumbles, leaving a rough, uneven soil surface. Earthworms are a large component of a mole’s diet, so their presence can result in increased tunneling by these small mammals.
Earthworm Activity and Its Benefits No pesticides are registered for earthworm control because of their generally beneficial contributions to soil health. These creatures break down accumulated thatch, pull organic matter into the soil, and dig tunnels that allow increased aeration and water penetration. They also mix large amounts of soil into the thatch layer. This helps to increase microbial activity and enhances growth of turf grass.
Earthworm activity depends directly on soil moisture and temperature. They become active when soil thaws in spring and move deeper as the soil warms and dries.
Management Options There are few options to reduce earthworm activity or to mitigate surface disturbance. A roller may be used to flatten castings. Some golf course managers top-dress with sand in areas where earthworms pose chronic problems. The thought is that this abrasive material will irritate the soft outer covering of earthworms and force them to relocate to sites where their activity is less objectionable.

A Note From Dennis So far so good with the winter weather! Granted we had a big snow, but it melted quickly and we had no subzero weather so our plants are still in good shape. I have stated here several times that I don’t like winter, however so far this one has been easier for me…..being very busy helps! Tori and Gabby have not had such a good winter, they have had more illnesses this year than the last five combined….I guess you have to catch up on all those bugs sooner or later to strengthen your immune system. Luckily they have parents with good benefits such as banked sick days so we can alternate who stays home with them. I just don’t know how single parents do it! If you haven’t had time to check out the new Wheelbarrow Series the class listing is enclosed and I hope to see you soon!
