Growing Green

By Robin Trott, Extension Educator

The erratic winter weather has left both plants and gardeners confused. With fluctuating temperatures swinging from unseasonably warm to frigid lows, our gardens have experienced false starts aplenty. To navigate this uncertainty, here’s a curated list of April garden chores to temper spring fever:

1. Monitor the Temperature: While perennials and hardy spring bulbs typically fare well, early annuals may require protection or temporary shelter indoors if the temperatures plummet into the 30s.

2. Start Seeds: Embrace the simplicity and enjoyment of starting seeds indoors. It’s a cost-effective way to experiment with new plants while nurturing your green thumb. (https://extension.umn.edu/planting-and-growing-guides/starting-seeds-indoors)

3. Proceed with Caution in Clean-Up: Resist the temptation to tidy up the garden prematurely during warm spells. Wait until consistent temperatures surpass 50°F for several consecutive days. Premature cleaning risks soil compaction and disturbs overwintering pollinators in plant debris.

4. Maintain Lawn: Follow University of Minnesota’s advice by applying preemergent crabgrass control around mid-April. Reserve fertilization for August and postpone mowing until the grass greens and the ground is firm. . (https://extension.umn.edu/planting-and-growing-guides/lawn-care-calendar)

5. Divide Perennials: As perennial growth appears, consider dividing those that need it. Focus on late summer and fall bloomers, such as hosta, during spring. Reserve division of spring and early summer bloomers for fall. (https://extension.umn.edu/planting-and-growing-guides/dividing-perennials)

6. Plant Bulbs: Once the frost retreats, seize the opportunity to plant lilies. However, exercise patience before planting dahlias, canna lilies and other tropical varieties, waiting until the weather fully warms.

7. Maintain Compost: When the compost pile thaws, give it a turn, collecting nutrient-rich compost to enrich plant beds and vegetable gardens. Avoid mulching until the soil warms sufficiently.

Navigating April’s garden chores requires a delicate dance, balancing the eagerness of Spring with the prudence demanded by nature’s whims. By following these guidelines, gardeners can navigate the transitional period with confidence, ensuring their garden thrives throughout the season.

Until Next Time, Happy Gardening!
