When to Plant Squash, Cucumbers, and Watermelons in Carlsbad, NM

For direct seeding in Carlsbad's climate, sow squash, cucumbers, and watermelons one week before your last expected spring frost. Given unpredictable spring weather, waiting an extra week provides insurance against late cold snaps.

Keys to Success

• Amend soil thoroughly with organic matter before planting
• Begin biweekly fertilization with high-phosphorus fertilizer once blooms appear
• Space vining plants 2 feet apart to prevent crowding—this ensures larger fruit and better yields

These warm-season crops are relatively straightforward once established. Your timing aligns well with the transition from cool nights to consistent warmth.
