Watermelon Seeds - Mountain Sweet Yellow, ORGANIC


Citrullus lanatus

HEIRLOOM. ORGANIC. Mountain Sweet Yellow Watermelon is aptly named! This very sweet yellow-fleshed fruit was developed in the Northeast from the well-loved red ‘Mountain Sweet’ watermelon. It gained popularity in the 1840s as a variety that outperformed other watermelons in those cooler growing regions. But don’t count it out if you live in the South! The Mountain Sweet Yellow Watermelon will still produce its largest fruits in long, warm summers. Yellow watermelons are said to be slightly sweeter than the classic reds. Find out for yourself!

The Mountain Sweet Yellow Watermelon grows 20-35 pound oblong fruits on 6-10 foot vines. Its flesh is a firm, bright yellow to golden orange color and its rind is striped light and dark green. You can either direct sow watermelon seeds outside or give them a head start indoors four weeks before your average last frost date, a wise choice if you have a short growing season. Either way, as with most cold-sensitive summer crops, wait until two weeks after your area’s average last frost date to get them outside to be sure that warm weather is here to stay. Where we are in Western NC, this typically means we’re planting watermelon seeds from the second half of May through the end of June.
