1. Survey the Yard:

Make note of tree limbs that should be removed or cabled, especially those that overhang structures. Hire an arborist to maintain large trees.Cut down last year’s perennial foliage, and toss it into the compost pile. Rake mulch from beds planted with bulbs before foliage appears, and refresh mulch in other planting areas after soil warms. Check fences, steps, and pathways for disrepair caused by freezing and thawing.

2. Order Tools and Plants:

Tune up tools so everything is ready when things start growing. Make note of what is missing, and order tools for the new growing season. Choose new plants for the garden. Order perennials, trees, and shrubs for spring planting.

3. Get Ready to Mow:

Send the mower and leaf blower for servicing, or if you have the right tools, sharpen the mower blades yourself. Refill your mower with oil, install fresh spark plugs, and lubricate moving parts if necessary. Clear the lawn of winter debris, and look for areas that need reseeding before mowing.

4. Prune Trees and Shrubs:

Remove dead, damaged, and diseased branches from woody plants. Thin and trim summer-blooming shrubs such as butterfly bush, hydrangea, and most roses, except for old-fashioned once bloomers. Prune cold-damaged wood after plants resume spring growth. Prune spring-blooming shrubs and trees after flowering.

5. Take a Soil Test:
Check soil pH with a home soil- test kit, taking several samples from different planting areas for an accurate reading. Enrich soil as necessary: Add dolomitic lime to raise the pH or elemental sulfur to lower the pH.

6. Prepare New Beds:

Clear the planting area as soon as soil can be worked, removing sod or weeds and debris. Spread a 4-inch layer of compost or well-rotted manure and any amendments over soil, and cultivate it to a depth of 10 to 12 inches with a spading fork.

7. Plant

Plant bare-root trees, shrubs, and perennials such as hostas and daylilies by early spring. Choose a cool, cloudy day if possible. Transplant container-grown plants anytime during the growing season except midsummer; be sure to water them thoroughly. Sow seeds of cool-season flowers like sweet peas, poppies, and calendula, and vegetables such as lettuce, parsley, and spinach.

8. Fertilize

Apply balanced fertilizer (6-6-6 or 8-8-8), fish emulsion, or other soil amendments recommended by soil-test results around trees and shrubs when new growth appears. Spread high-acid fertilizer and pine-needle mulch around acid-loving shrubs like azaleas and camellias. Begin fertilizing perennials when active growth resumes.

9. Start a Compost Pile

Start a compost pile, or use a compost bin, if you don’t have one already. Begin by collecting plant debris and leaves raked up from the garden. Chop these up first to speed decomposition. Add equal amounts “brown” (carbon-rich) materials like dried leaves and straw and “green” (nitrogen-rich) materials like grass clippings and weeds in even layers with water and a compost bioactivator. Turn regularly. Continue adding to the pile throughout the season for rich, homemade compost next spring.

10. Clean Bird Feeders and Baths

Disinfect the feeders by scrubbing with weak bleach solution (1/4 cup bleach: 2 gallons warm water). Rinse and dry the feeders thoroughly before refilling them.Scrub birdbaths with bleach solution, then rinse them thoroughly and refill, changing water weekly. Clean birdbaths and feeders regularly throughout the season.
