🛠️ Growing Tips

• Water consistently during fruit development, but reduce slightly before harvest for optimal sweetness.

• Hand-pollinate early blooms for improved fruit set if pollinators are scarce.

• Use mulch to retain moisture and reduce weed competition.

• Let the fruit fully ripen on the vine—look for a creamy yellow spot on the bottom and a dry tendril near the stem.

• For earlier harvests, try growing on black plastic or mounds to warm soil faster.
