All it takes for some of us to get Spring Fever is one nice day in February. Although February is too early for most planting, some tasks that may need to be done are listed below along with applicable fact sheets containing additional information and are available at http://osufacts.okstate.edu or can be found by simply searching for the Fact Sheet number, e.g., HLA 6409.
• Base fertilizer application on a soil test. Soil test instructions and cost are available at the following link: http://oces.okstate.edu;
• A product containing glyphosate plus a broadleaf herbicide can be used on dormant Bermuda in January or February when temperatures are above 50 degrees Fahrenheit for winter weed control. (HLA-6421 – Controlling Weeds in Home Lawns); and
• Pre-emergent crabgrass control chemicals can still be applied to cool and warm-season turf grasses. Heed label cautions when using any weed killers near or in the root zone of desirable plantings. (HLA-6421 – Controlling Weeds in Home Lawns).
Trees & Shrubs:
• Fertilize ornamental, fruit, and nut trees and shrubs, annually. (HLA-6112 – Fertilizing Shade and Ornamental Trees and Shrubs);
• Finish pruning shade trees, summer flowering shrubs, and hedges. Spring blooming shrubs such as forsythia may be pruned immediately after flowering. (HLA- 6409 - Pruning Ornamental Trees and Shrubs);
• Roses are on the pruning list for March, but it is best to prune before new growth begins which could be in February;
• Many bare-rooted trees and shrubs should be planted in February or early-March. (HLA-6414 – Planting Shade Trees and Shrubs);
• Dormant oil can still be applied to control mites, galls, overwintering aphids, etc. (EPP-7306 – Ornamental and Lawn Pest Control);
• Spray peaches and nectarines with a fungicide for prevention of peach leaf curl before bud swell. (EPP-7319 – Home Tree Fruit Production and Pest Management); and
• Place Nantucket pine tip moth pheromone traps by March 1.
• Begin the vegetable garden with cool-season crops such as potatoes, onions, and radishes. (HLA-6004 – Oklahoma Garden Planning Guide); and
• Usually few insects are active in February, but preplant applications for cutworms, white grubs, and wireworms can be made, if needed, in late February.
