Early May marks one of the most important turning points of the gardening season in south Arkansas. With warm temperatures settling in and the threat of frost long gone, local gardeners are entering a narrow but productive window to get summer crops established before the region’s intense heat arrives.
For those gardening in Zone 8a, the first week of May is a “now or never” moment for several popular plants, while also signaling the end of the line for cool-season vegetables.
What to plant right now
Warm-season crops thrive in the rising soil temperatures of early May, making this an ideal time to plant:
- Okra
- Southern peas (purple hull, black-eyed peas)
- Cucumbers
- Watermelons and cantaloupes
- Sweet potatoes (slips)
- Basil and other heat-loving herbs
These crops benefit from getting established now, giving them time to grow strong before the peak heat of June and July.
Last call for these crops
Gardeners still have a short window to plant:
- Tomatoes
- Peppers
- Squash and zucchini
While these can still be planted, the window is closing quickly. Plants set out now may produce later and face more stress as summer temperatures climb.
Ornamentals still safe to plant
For those looking to add color to flower beds and landscapes, several heat-tolerant options can still be planted successfully:
- Zinnias
- Vinca (periwinkle)
- Lantana
- Salvia
These plants handle Arkansas heat well and will provide color throughout the summer months.
What is likely too late
Cool-season crops are reaching the end of their viability for spring planting. Most gardeners will find it too late to successfully start:
- Lettuce
- Spinach
- Broccoli
- Cauliflower
Rising nighttime temperatures can cause these crops to bolt quickly, reducing quality and yield.
Watch for pests and disease
As temperatures rise, so does insect activity. Gardeners should begin monitoring for:
- Aphids
- Squash bugs
- Cucumber beetles
Catching infestations early can prevent significant damage later in the season.
Watering and maintenance tips
Consistent care becomes more important heading into late spring. Gardeners are encouraged to:
- Water deeply in the early morning
- Apply mulch to retain soil moisture and reduce weeds
- Check soil regularly to avoid overwatering or drying out
Mulching, in particular, can make a significant difference in maintaining plant health during the hotter months ahead.
With summer just around the corner, early May offers a final opportunity to set the stage for a productive garden. Taking advantage of this window can help ensure strong plants, better yields, and a more manageable growing season as south Arkansas heat begins to intensify.
