July in Wakulla County, Florida — your action list
We've pulled the most time-sensitive tasks for Wakulla County, Florida this July and put them front and centre. Tackle them in order.
Bearded Iris (Iris germanica) are among the most regal flowers of the late-spring garden, producing elegantly ruffled blooms in virtually every color of the rainbow — often in spectacular bicolor combinations. Named for the fuzzy "beard" on the lower falls (petals), bearded irises grow from thick horizontal rhizomes that spread to form dense clumps over time. Individual blooms last only a few days, but a well-established clump produces successive flowers over 3–4 weeks. Many are intensely fragrant. Native iris species including blue flag iris (I. versicolor) and Virginia iris (I. virginica) are excellent choices for wet or native garden settings.
Wakulla County, Florida is in USDA Zone 9a. The average last spring frost is March 13 and the first fall frost is November 22, giving you a growing season of approximately 254 days.
At an elevation of 375 feet, Wakulla County receives approximately 48.4 inches of rainfall annually with predominantly sand soil. Summer highs average 95°F, so Irises may need afternoon shade and extra watering during peak heat. Sandy soil warms quickly in spring — great for early planting — but Irises will need more frequent watering and organic matter to retain nutrients.

Irises 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 Irises in Wakulla County
Direct sow Irises outdoors after March 13 in Wakulla County when soil has warmed and frost danger has passed.
Sandy soil in Wakulla County dries quickly — mulch Irises with 2-3 inches of straw and water deeply 2-3 times per week rather than lightly every day.
General growing tips
Plant rhizomes in late summer to early fall (July–September) after bloom season, setting them horizontally with the top of the rhizome at or just slightly below soil surface — never deeply buried. Full sun is essential for best bloom; at least 6 hours. Well-drained soil is critical; wet rhizomes rot in winter. After bloom, remove flower stalks but leave foliage until it browns in fall. Divide every 3–5 years in late summer when clumps become congested (crowded rhizomes stop blooming). Iris borer is the primary pest — remove and destroy affected fans. Year 2+ after division delivers the most bloom; freshly divided rhizomes may have limited or no bloom in their first season.
