- Focus exclusively on sowing Garlic now; the soil is too cold and risky for transplanting any other crops until after March 28.
- Take advantage of the narrow window to plant Daikon Radish seeds immediately if you haven't already, as they are ready for harvest soon.
- Oklahoma's clay-heavy soils tend to freeze deeper than sandy areas, so wait for that official frost date before moving seedlings outdoors.

Seasonal tips
- Finish harvesting cool-season crops like Daikon radish before temperatures drop too low.
- Plant cover crops or winter rye now to protect soil structure during the dormant season.
- Apply a thick layer of mulch around garlic plants to insulate bulbs from freezing ground.
Pest & disease watch
- Watch for early aphid colonies emerging on bulb plants as temperatures rise above 50°F.
- Monitor soil moisture closely; Oklahoma's erratic spring rainfall can lead to root rot if clay soils stay waterlogged too long.
- Be ready for cutworm activity in the garden beds as caterpillars emerge with the increasing day length.
Watering this week
Water garlic lightly and only when the soil is dry, avoiding wetting the bulbs directly to prevent rot.
Store your freshly harvested Daikon radishes in a cool, humid place like a crisper drawer or sand-filled bin.
