Pajaro Valley Growing Strategies
Take Advantage of Your Extended Season
Succession planting is key:
Tomatoes: Plant early varieties in April, late varieties in May-June
Beans: Every 2-3 weeks through July
Corn: Every 2-3 weeks through June
Lettuce: Every 2-3 weeks fall through spring
Push the boundaries:
Late tomato plantings (June) still ripen in your warm fall
Melons are possible where they fail elsewhere
Extended harvest through November for many crops
Manage Summer Heat (80-90°F is manageable, not extreme)
Irrigation:
Drip irrigation recommended
Deep watering 2-3x per week in summer
More frequent for containers and new transplants
Clay soils retain moisture well
Mulching:
3-4 inches organic mulch (not as critical as inland mountains but still helpful)
Conserves moisture
Moderates soil temperature
Suppresses weeds
Heat management:
Most crops handle your heat well
Afternoon shade helpful for transplanting brassicas in August
Generally less dramatic than inland mountain areas
Soil Management
Pajaro Valley soils:
Often clay-loam (fertile but can be heavy)
Good nutrient retention
Drainage can be issue in some areas
May need organic matter amendment
Amendments:
Compost annually (2-4 inches)
Gypsum for clay soils (improves structure)
Cover crops in winter (fava beans excellent)
pH: Usually 6.0-7.0 (good for vegetables)
Frost Protection (Minimal Need)
Frost is rare but possible:
2-3 nights per winter might frost
Usually light frost only
Most damage to tender crops (tomatoes, basil, peppers)
Protection strategies:
Row covers for tender fall plantings
Don't plant tomatoes until April (frost risk over)
Most crops don't need protection
Pest & Disease Considerations
Gophers: Major issue in agricultural areas
Wire baskets for valuable plants
Trapping programs
Raised beds with hardware cloth bottom
Deer: Less pressure than mountain areas but present
Fencing if needed
Deer-resistant crops
Aphids: Common on brassicas and other crops
Spray off with water
Beneficial insects
Insecticidal soap
What you don't deal with:
Less slug pressure than coastal/shaded areas
Less extreme heat stress than inland mountains
Minimal frost damage
