<p class="lede" style="font-size:1.15rem;border-left:4px solid var(--clay);padding-left:1.1rem;margin:1.2rem 0;">Two dates bracket everything you'll do in this garden: the last frost of spring and the first frost of fall. Call them right and you've bought yourself every growing day on the calendar. Call them wrong and you've cooked a season's seed money.</p>
<h2>Why the Dates Matter More Than Any Fertilizer</h2>
<p>Frost isn't a weather event so much as a <em>deadline</em> — the point where the ground stops cooperating and every tender plant folds its hands. Warm-season crops like sweet potato slips and corn die outright at a hard frost. Cool-season crops like collards don't mind a light nip — a frost actually <b>sweetens a collard</b>, turning its starch to sugar. So the frost call separates the whole garden into two shifts, same as a factory split.</p>
<p>Robeson County sits in the coastal plain, warmed by the rivers and the low elevation. Our window is wide but not guaranteed:</p>
<table>
<tr><th>Event</th><th>Typical Window</th><th>Read</th></tr>
<tr><td>Last killer frost of spring</td><td class="num">mid-March</td><td>After this, tender sets go in</td></tr>
<tr><td>First killer frost of fall</td><td class="num">early November</td><td>Before this, everything comes out or is covered</td></tr>
<tr><td>Working season</td><td class="num">~220+ days</td><td>Long enough for a full sweet potato cure</td></tr>
</table>
<p>Those are my ten-year running averages, logged every season like a maintenance clock. Treat them as <b>anchor dates, not promises</b> — a low-pressure trough can shove the frost line a week either way.</p>
<h2>The Decision Procedure — in Order Trouble Arrives</h2>
<p>Same structure I used to clear a line fault in the factory: check the indicators in sequence, make one call, don't second-guess the machine.</p>
<ol>
<li><b>Watch the ten-day forecast in mid-March.</b> If any night dips below <span class="num">~36°F</span> inside that window, hold the tender sets. Morning ground temperatures under <span class="num">50°F</span> stall sweet potato slips at the roots — cold soil rots more slips than frost ever does.</li>
<li><b>Read the soil, not just the sky.</b> A seed germinates at soil temperature, not air temperature. My four-inch soil thermometer saying <span class="num">60°F</span> at 8am is worth more than any date on the calendar. Sweet potato slips want <span class="num">soil at 6065°F</span> and rising.</li>
<li><b>Make one call and commit.</b> If the ten-day shows clear and soil reads warm, everything tender goes in that weekend. Half-planting hedging is how you lose the whole line to hesitation.</li>
<li><b>Fall is the mirror.</b> When the forecast shows the first <span class="num">~36°F</span> night in November, dig the sweet potatoes <em>before</em> it — a bruised or chilled tuber won't cure. The tender stuff: harvest or cover, same call.</li>
</ol>
<blockquote>"I've seen a man wait two weeks past a good call because the almanac said wait. The ground don't read the almanac. It reads the thermometer and the sky, same as a machine reads its gauges."</blockquote>
<div class="callout">
<b>FIELD NOTE · 2026:</b> The frost call landed a week early this year — came in around the second week of March, not the third. Same kind of surprise I found in the hydraulic logs back in '87. Keep the pencil moving. Ten years of notes beat any almanac, because the notes are <em>your</em> machine's history.
</div>
<h2>The Two-Calendar Habit</h2>
<p>I keep two calendars: the wall one for planting days, and a plain notebook where I write down, every season, the actual frost dates and the day I set each crop. After a decade that notebook is the single most valuable thing I own for growing. It knows <em>this</em> plot's microclimate — the low corner that frosts two days early, the raised beds along the south wall that run a week ahead of the flat ground.</p>
<p>Read that and the frost call becomes a formality. You already know what this ground is going to do.</p>
