No season owns Hilltop's rain: March reaches 4.7 inches across 16.3 days and October keeps 2.3 inches on 10.1, an even spread through Hilltop's year. It is a balanced pattern Hilltop shares with places like Saxon, SC, Whitney, SC and Southern Shops, SC.

Around mid-March, Hilltop sheds its freezing nights — peas, lettuce, spinach, and radishes go into Hilltop's beds. Hilltop's heat-lovers — tomatoes, peppers, squash — hold off until Hilltop's frost risk clears, 10-14 days on. By mid-December, frost is back in Hilltop — protect or harvest anything tender. Hilltop's low ground holds frost later into spring than Hilltop's benches, which run 3-5 days ahead.
