What to-Do in the Garden in March

1. Plant warm-season vegetables such as tomatoes, peppers, cucumbers, squash, and beans. Choose a sunny, well-drained location and prepare the soil by adding compost or other organic matter.
2. Start planting annual flowers such as petunias, marigolds, and zinnias. Water regularly and apply a balanced fertilizer to promote healthy growth and abundant blooms.
3. Fertilize lawns with a slow-release, high-nitrogen fertilizer such as Nitro Phos Imperial or for an organic approach use the Microlife general purpose fertilizer. Water thoroughly after applying to ensure that the fertilizer is absorbed by the roots and not washed away.
4. Divide and transplant perennials such as daylilies, hostas, and irises. Dig up the plants and separate the root clumps, then replant in a sunny or shady location with well-drained soil.
5. Control weeds by hand-pulling or using a hoe or cultivator. Apply mulch around garden plants to suppress weed growth and retain moisture.
6. Monitor for pests and diseases, and treat as needed. Common pests in March include aphids, whiteflies, and spider mites, while fungal diseases can thrive in warm, humid weather.
7. Water deeply once or twice a week, depending on rainfall and soil conditions. Avoid overhead watering, which can promote fungal diseases and waste water.
8. Prune summer-blooming shrubs such as crape myrtle and butterfly bush. Remove any dead, damaged, or crossing branches, and shape the plants as desired.
9. Plant herbs such as basil, parsley, and cilantro in containers or garden beds. Choose a location with well-drained soil and partial shade to prevent the plants from wilting in the hot sun.
10. Start a compost pile or add to an existing one. Composting yard waste and kitchen scraps can help reduce waste and produce rich, organic soil amendment for your garden.
11. Plan and prepare for the upcoming gardening season. Make a list of new plants to try, sketch out a garden layout, and order seeds or plants as needed.
