This Week in the Ozarks
A warming trend continues, with highs pushing into the mid–upper 70s. Mornings remain mild in the 50s. Conditions are no longer steadily drying — moisture is returning, with multiple chances for showers and thunderstorms building through the weekend into early next week. Soil surfaces may firm briefly between rains but will not stay dry for long.
Leaf-out has moved into a fuller phase. Oaks and hickories are now casting consistent shade, and understory plants are adjusting accordingly. The brief window of high light on the forest floor is closing. Grasses along roadsides have thickened, and mowing has begun in earnest across open ground.
Creeks are running at moderate levels with improved clarity compared to mid-month. Gravel bars are reappearing, and insect activity along the water’s edge has picked up. Evenings remain active but less intense than earlier in April, with frog and toad calls no longer at peak volume.
Air movement has been variable, with calmer, more humid stretches building ahead of storm systems. Exposed ground may dry briefly, but moisture is returning quickly. The overall feel is a transition week—less surge, more settling into late spring rhythm.

What’s Blooming
Red clover is beginning to show in open fields. Wild geranium and spiderwort are now established along woodland edges. Blackberry brambles are leafed out and forming buds, with early blooms beginning in sunnier patches. Early fleabane beginning in disturbed ground and gravel edges.
Flowering dogwood is near peak but will begin to fade through this week, especially with warmer daytime temperatures. In shaded areas, blooms are holding longer.
One Animal Moment — White-tailed Deer
White-tailed deer are shifting into a more predictable feeding pattern this week. With new plant growth abundant, movement is concentrated along edge habitats—field margins, young clearings, and roadside ditches.
Does are feeding heavily in preparation for fawning, which will begin within the next few weeks. Their behavior is noticeably focused, with longer feeding periods during early morning and dusk.
Bucks remain solitary or in small bachelor groups, spending more time in cover as antler growth continues under velvet. Tracks are more visible now in soft soil, especially near water crossings and mineral-rich ground.
One Stone Study — Dolomite
Much of the Ozarks rests on dolomite, a sedimentary rock formed in shallow inland seas hundreds of millions of years ago. It resembles limestone but contains magnesium, which makes it more resistant to weathering.
Because of that durability, dolomite often holds as bluffs, ledges, and arly fleabane beginning in disturbed ground and gravel edges while surrounding material erodes away. Water works slowly into fractures, widening them over long periods.
Near Dixon, the Clifty Creek Arch Bridge shows this process in place. The opening reflects steady weakening along a fracture line rather than a sudden break. Surfaces there are rough and angular, with small ledges where material has gradually separated.
This same resistance shapes the ground above it—thin, rocky soils that drain quickly and favor plants adapted to limited moisture.
Backyard Nature & What to Plant
Soil temperatures are now consistently suitable for direct sowing of warm-season crops. Beans, squash, and cucumbers can begin going in toward the end of the week in warmer, well-drained soils. Earlier plantings carry some risk if temperatures dip or soils cool after rain.
Tomato and pepper transplants can begin going out in protected or favorable spots, especially where overnight lows stay near or above 50°F.
Mulching becomes important now. A light layer helps retain soil moisture as winds continue to dry the surface. Watch for early insect activity on tender starts, particularly in sheltered garden beds.
Cool-season crops like lettuce may begin to bolt with the warming trend. Successive sowings in partial shade can extend the harvest window.
Dirt Under Fingernails Notes
First sustained stretch of frost-free nights is holding.
Soil workable across most upland areas; low spots still soft underneath.
Dogwood bloom nearing its turnover point.
Deer activity increasing along garden edges—early protection may be needed.
First noticeable mosquito presence in low, still areas after rain
Transition week: spring surge easing into steady growth.
