3. Choosing Seeds or Tubers

  • Seeds vs. Tubers: Most gardeners start jicama from seeds, which are readily available and can be germinated indoors to start early in regions with shorter growing seasons. Seeds offer greater variety choice and are generally easier to obtain. Tubers, although less commonly used, can be an option if you wish to propagate from existing plants, though they require careful handling to ensure they are disease-free.
  • Quality and Source: Select high-quality, certified disease-free seeds or tubers from reputable suppliers to increase your chances of a healthy and productive crop. Fresh, viable seeds have a higher germination rate, leading to more vigorous plants. When purchasing, look for seeds that are plump, uniform in color, and free from any signs of damage or mold.
  • Preparation for Planting: For seeds, consider a pre-planting soak for 24 hours to enhance germination rates. This process, known as seed priming, can significantly improve germination speed and uniformity. If using tubers, inspect carefully for any signs of rot or damage before planting. Healthy tubers should be firm and free from soft spots or discoloration.
  • Seed Viability: Jicama seeds typically remain viable for about 2-3 years when stored properly in a cool, dry place. If using older seeds, consider conducting a germination test before planting to ensure they are still viable.
  • Genetic Diversity: If you’re interested in seed saving or developing your own jicama strains, starting from seeds allows for greater genetic diversity. This can be beneficial for adapting the plant to your specific growing conditions over time.

III. Preparing the Soil and Planting

To ensure your jicama plants thrive, the right soil conditions and proper planting techniques are essential. This section will guide you through preparing your garden bed, choosing the best site, and the specifics of planting jicama, whether you start from seeds or tubers.

1. Ideal Soil Conditions for Jicama Growth

Jicama prefers slightly acidic to neutral soil, with a pH range of 6.0 to 7.0. Excellent drainage is crucial as jicama roots are prone to rot in waterlogged soil. To create the optimal growing environment:

  • Soil Texture: Aim for a light, sandy loam that allows for good drainage while retaining some moisture. Heavy clay soils should be amended with sand and organic matter to improve drainage.
  • Organic Matter: Incorporate plenty of well-rotted compost or aged manure into the soil. This not only improves soil structure and drainage but also provides slow-release nutrients throughout the growing season.
  • Soil Testing: Conduct a soil test before planting to determine your soil’s pH and nutrient levels. This will guide you in making any necessary amendments.
  • Soil Depth: Ensure a deep tillage of at least 12-15 inches (30-38 cm) to accommodate jicama’s long taproots.

2. Site Selection and Preparation

  • Choosing a Sunny Location: Jicama requires a full sun location to produce well. Select a site that receives at least 6 to 8 hours of direct sunlight daily. The area should be protected from strong winds which can damage the vine growth. Consider using windbreaks if necessary.
  • Amending the Soil for Optimal Growth: Till the soil to a depth of about 12-15 inches (30-38 cm) and mix in organic amendments thoroughly. This not only improves the soil’s fertility and texture but also ensures that the deep roots of jicama can penetrate easily. Consider raised beds if natural soil drainage is poor.
  • Soil Temperature: Jicama thrives in warm soil. Wait until soil temperatures consistently reach 68°F (20°C) before planting. Using black plastic mulch can help warm the soil in cooler regions.
  • Crop Rotation: Avoid planting jicama in areas where legumes have grown in the previous season to prevent disease buildup.

3. Growing Jicama from Seeds

  • Timing and Spacing: Plant jicama seeds after the last frost date when soil temperatures consistently reach 68°F (20°C). Cold soil can hinder germination and slow growth. Space seeds 8-12 inches (20-30 cm) apart, with rows 2-3 feet (60-90 cm) apart. This spacing allows for proper air circulation, ease of maintenance, and optimal tuber development.
  • Planting Depth and Technique: Sow seeds 1 inch (2.5 cm) deep. This depth protects seeds from birds and helps maintain consistent moisture. After planting, water gently but thoroughly to settle the soil around the seeds. Maintain consistent soil moisture during germination, which typically takes 7-14 days.
  • Pre-Sowing Treatment: To enhance germination rates, consider scarifying the seeds lightly with sandpaper and soaking them in warm water for 24 hours before planting. This can significantly improve germination speed and uniformity.
  • Thinning: Once seedlings reach 2-3 inches (5-7.5 cm) tall, thin them to the recommended spacing. Choose the strongest seedlings to keep, and remove others by cutting at soil level to avoid disturbing the roots of remaining plants.

4. Growing Jicama from Tubers

  • Timing and Spacing: Plant jicama tubers after the last frost when soil temperatures are consistently warm. Space tubers 8-12 inches (20-30 cm) apart in rows 2-3 feet (60-90 cm) apart. This spacing ensures each plant has sufficient room for root expansion and vine growth.
  • Planting Depth and Technique: Plant tubers with sprouts facing upward, no more than 2 inches (5 cm) below the soil surface. Deeper planting can delay sprouting and potentially lead to rot. After planting, water thoroughly to encourage root establishment.
  • Tuber Selection: Choose firm, disease-free tubers for planting. Avoid any with soft spots, discoloration, or signs of damage. Larger tubers often produce more vigorous plants.
  • Pre-Planting Care: If tubers have long sprouts, you can cut them back to about 1 inch (2.5 cm) before planting. Allow cut surfaces to dry for a day before planting to reduce the risk of rot.

5. Growing Jicama in Containers

  • Container Size: Use a large container, at least 18 inches (45 cm) deep and 20 inches (50 cm) in diameter. Jicama’s extensive root system requires ample space for proper development.
  • Soil Preparation: Use a well-draining potting mix enriched with compost. Ensure a pH between 6.0 and 7.0. Adding perlite or coarse sand can improve drainage.
  • Planting Depth and Spacing: Follow the same planting depth as in-ground cultivation: 1 inch (2.5 cm) for seeds, 2 inches (5 cm) for tubers. In large containers, you can grow 2-3 plants, spaced 8-12 inches (20-30 cm) apart.
  • Watering: Monitor soil moisture closely, as containers dry out faster than garden beds. Water deeply when the top inch of soil feels dry, ensuring good drainage to prevent waterlogging.
  • Fertilization: Apply a balanced, slow-release fertilizer at planting time. Supplement with liquid fertilizer every 4-6 weeks during the growing season, focusing on phosphorus and potassium to promote root development.
  • Sunlight and Positioning: Place containers in a location receiving full sun, at least 6-8 hours daily. Consider using wheels or a plant dolly for large containers to easily move them if needed.
  • Support for Vines: Provide a trellis or stakes in the container for vine support. This not only saves space but also keeps the plant tidy and improves air circulation.
  • Winter Care: In colder regions, bring containers indoors or to a protected area during winter to prevent frost damage to the roots.
Additional Planting Tips
  • Succession Planting: For a continuous harvest, consider planting jicama every 3-4 weeks throughout the growing season, as long as you have at least 5-6 months of warm weather remaining.
  • Companion Planting: Plant jicama near corn, which can provide natural support for the vines, or alongside nitrogen-fixing legumes like beans to improve soil fertility.
  • Mulching: After planting, apply a 2-3 inch (5-7.5 cm) layer of organic mulch around plants to conserve moisture, suppress weeds, and regulate soil temperature.
  • Frost Protection: In areas with short growing seasons, consider using row covers or hoop houses to extend the growing period and protect plants from early frosts.
