Yields and How Much is Too Much !
Reasons to Extend Season
Stretch invested dollars
Higher yields
Better quality
Approaches to Extended Market Season
Stagger Production
Grow in the Cold
Row covers
Row tunnels
High tunnels
Transplants
Mulches
Low Tunnels
Often better before or after regular season
Methods to Increase Earliness
Site selection Well drained warm up sooner
Slope of land land sloping 20o towards south 6% warmer land sloping 20o towards north 19% colder
Soil Texture Light soils have greater temp swings (frost prone) Heavy soils more constant temp
Variety selection Early maturity Cold tolerance/germination

Methods to Increase Earliness
Use of windbreaks (50-70 ft apart)
Plant protectors
caps
Row covers
Methods to Increase Earliness
Plastic Mulch Gain of 1-2 weeks Increase early and total yield
Use of transplants Larger cell size earlier yield Proper transplant age Set at proper time Use starter fertilizer

Good to cover fences or arbors
Full sun preferred
African Horned Melon
Very vigorous vine
Sharp thorns on fruit and vines are barbed
Fruit tastes like a mix of citrus and kiwi,
used in drinks
Takes a long time to set fruit; worth the wait
Calabaza Winter Squash
This variety is “La Estrella” and is similar to a pumpkin in taste
Very large fruit, size of a basketball

Favorite of Asian and
Indian cuisine
Many different varieties and colors
Luffa Gourd
Edible, though bitter when very small
Dry out completely, then soak and remove outer skin to make sponges
Vines are very fast growing and need something to climb on
Full sun
Pumpkins and Gourds
Wonderful for children
Give plenty of room to grow along with water and sunlight
Try just one along a
fence, trellis, or arbor
If space is limited, there are bush varieties available

Pineapple Sage
Flowers and leaves smell like pineapple
Good plant for flower border as well as herb bed
Full sun and good drainage needed
Attracts bees and butterflies

Tomatoes Origin of the Tomato
West coast of South America (Peru)
8 species in the tomato genus grow wild in
Andes Mountains.

Family Solanaceae ( tomato, potato, pepper, eggplant)
Genus Lycopersicon
Wild tomatoes tiny fruits and only red are edible.
Perennials in warmer regions, annuals in colder regions.
What is an Heirloom Tomato ?
An heirloom is generally considered to be a variety that has been passed down, through several generations of a family because of it’s valued characteristics.

Beefsteak fruits are 5 to 6 inches in diameter and weigh one pound or more.
Sweet juicy flesh, refreshing spicy flavor. Thick green slices are great in sandwiches.
Produces fruit in late season and in cooler climates.
Brandywine, Pink (SUDDUTH/QUISENBERRY STRAIN)

irrigation
Copper based fungicides
Vascular Wilts Fusarium, Verticillium
Fungal diseases, spores long lived in soils
Symptoms identical, wilting one side of plant, turns yellow and dies
Fusarium more common extended hot temps.
Vascular Wilts Control
Use resistant varieties
Rotate out of tomatoes and other solanaceous crops
Reduce stress
even watering
Balanced fertility

When third true leaf apopears, grow plants at min night of 53-55 deg for 4 weeks, then adjust to 70 deg day and night
Sow seeds 1 to 2 weeks earlier than usual with this technique
Peppers
