Successful Fall Harvest

Achieve a Bountiful Fall Garden with these Recommended Crops for Arizona


Growing Chard Tips:

  • Sunlight Requirements: Chard prefers 6 to 8 hours of sunlight but can tolerate partial shade (4 to 6 hours of sun).
  • Soil Preparation: Chard thrives in organic-rich, well-drained soil. Before planting, amend the soil with compost.
  • Starting from Seed: To begin from seed, sow chard seeds ½ to 1 inch deep, spacing them about 2 to 6 inches apart in rows that are 18 to 24 inches apart. In square foot gardening, plant 4 per square. Each seed comprises a cluster of multiple seeds.
  • Thinning Seedlings: When chard seedlings reach 3 to 4 inches in height, thin them to one plant per hole. As the plants grow a bit more, thin them to around 6 inches apart. For larger plants, thin to 12 inches apart.
  • Planting Transplants: When using transplants, select healthy young plants that have not outgrown their containers. Separate individual plants if more than one is present. Space transplants 6 to 8 inches apart, keeping them at the same depth as their nursery pots.
  • Crop Rotation: To prevent soil-borne diseases and nutrient depletion, rotate the location for chard and other beet family members in subsequent seasons.
  • Container Gardening: Chard can be grown in containers that are at least 8 inches deep and can hold approximately 2 gallons of soil. Maintain consistent moisture in container-grown chard.
  • Fertilization: Once chard plants are established, feed them with a balanced organic fertilizer every 6 weeks.
  • Pest Prevention: Chard is relatively resistant to pests, but check for holes in leaves and inspect the undersides for cabbage worms. Use row covers to deter aphids, cabbage worms, flea beetles, and leaf miners if they are present in significant numbers.

Brussels Sprouts

Tips for Growing Brussels Sprouts:

  • Planting Time: The ideal time to plant Brussels sprouts depends on your climate and whether you are starting from seeds or transplanting seedlings. If starting from seeds indoors, begin about 8 weeks before outdoor planting. For a fall harvest, transplant seeds or seedlings approximately 10 weeks before the expected first fall frost date.
  • Soil Preparation: Brussels sprouts thrive in compost-rich, fertile, and well-draining soil. Add additional compost to the planting area and work it into the soil.
  • Spacing: When planting seeds outdoors, sow them ¼ to ½ inch deep and space them about 4 inches apart. Once seedlings have two sets of leaves, thin them to 1-2 feet apart. For square-foot gardening, place 1 per 1-2 squares.
  • Watering: Water newly-planted Brussels sprouts thoroughly. Do not let transplants dry out or become stunted if you are using seedlings.
  • Mulching: Apply 2-3 inches of mulch around plants to maintain soil moisture and prevent weed growth.
  • Fertilization: Feed Brussels sprouts with compost before planting and once or twice during the growing season, using fish emulsion.
  • Sunlight: While Brussels sprouts prefer cooler weather, they grow best in locations with abundant sunlight.
  • Crop Rotation: In subsequent seasons, rotate the location for Brussels sprouts in your garden to prevent soil-borne diseases and nutrient depletion.
  • Staking: If your area is windy, consider staking Brussels sprouts at planting to avoid disturbing roots later on.


Cultivating Rhubarb:

  • Planting Single Rhubarb: Dig a hole at least 2 feet in diameter and depth. Partially back-fill with a 50/50 mixture of soil and compost or well-rotted manure.
  • Planting multiple plants: dig a trench with about 3 feet of space between them. Mound the soil, spreading the roots over the mound's sides, and cover so the buds are 1 to 2 inches below the surface. Tamp the soil and water well.
  • Watering: As new growth emerges, provide at least an inch of water per week.


How To Grow a High-Yielding Spinach Crop:

  • Sunlight: Choose a spot with partial shade to protect spinach from intense midday sun.
  • Temperature Requirements: Spinach prefers temperatures between 25°F and 75°F (-3.9°C and 23.9°C). In cold winter areas, plant as soon as the soil can be worked. Spinach requires about 6 weeks of cool weather from seed to harvest and can withstand moderate frost.
  • Soil Preparation: Spinach thrives in moist, fertile soil with a neutral to alkaline pH (7.0 or above). Amend the soil with 2-4 inches of compost before planting.
  • Planting Seeds: Sow seeds directly in the soil or start seeds indoors about 6 weeks before outdoor planting. Gradually acclimate seedlings to outdoor conditions before transplanting.
  • Spacing: Plant seeds ½ inch deep and 2-4 inches apart. Thin to 1 plant every 4-6 inches when seedlings are 2-3 inches tall. For square-foot gardening, plant 4-9 per square.
  • Moisture and Feeding: Keep the soil consistently moist but not waterlogged. Mulch plants to retain moisture. Feed with seaweed or compost tea regularly.
  • Pest Prevention: Use row covers to prevent pests like leaf miners and pick off damaged leaves as needed.
