Jefferson Davis County, Mississippi gardeners: here's your August plan
Your Jefferson Davis County, Mississippi garden is entering a new phase. Here's what's on the schedule for August and why each task matters now.
Crocuses (Crocus spp.) are the heralds of spring — small, gem-like blooms that push up through frozen ground or even snow, often weeks before any other flower. Their compact corms naturalize readily in lawns, rock gardens, and borders, creating drifts of purple, white, and yellow that expand year after year. Bees prize early crocus as one of their first nectar and pollen sources of the season. The saffron crocus (C. sativus) blooms in fall and yields the world's most expensive spice.
Carson, Mississippi is in USDA Zone 8b. The average last spring frost is March 8 and the first fall frost is November 19, giving you a growing season of approximately 256 days.

Crocus Heat Requirements (GDD)
What are Growing Degree Days (GDD)?
Growing Degree Days measure the total warmth your plants receive during the growing season. Think of it as a "heat bank" — every day above 50°F deposits warmth that helps your plants grow.
Each plant needs a certain amount of accumulated heat to mature. If your county provides more GDD than the plant needs, it's a great fit. If it's close, you may want to choose faster-maturing varieties or start seeds indoors to get a head start.

Growing Tips for Crocus in Carson
Direct sow Crocus outdoors after March 08 in Jefferson Davis County when soil has warmed and frost danger has passed.
With Jefferson Davis County's clay soil (31% clay), work in 3-4 inches of compost before planting Crocus. Avoid tilling when soil is wet to prevent compaction.
Your generous 256.0-day season in Jefferson Davis County allows multiple plantings of Crocus. Sow every 5.0 days for continuous harvest.
General growing tips
Plant corms 3–4 inches deep and 2–3 inches apart in fall, when soil temperature drops below 60°F. Mass plantings (at least 25 corms per cluster) create the most visual impact. Plant in well-drained soil — corms rot in standing water. Crocus naturalize well under deciduous trees; the tree leafs out after crocus dormancy begins, so light competition is minimal. Squirrels and chipmunks dig corms — plant deeper (4 inches) or use wire mesh baskets in high-predation areas. Allow foliage to die back naturally before mowing lawns. In zones 8a–8b, plant in December with pre-chilled corms for best results.
