Beans (Phaseolus vulgaris & P. linensis)
•
•
•
•
•
Family Fabaceae (Leguminoseae)
Native to Central America
Records of use as food date back to 5000 B.C.
Self-pollinated
Warm season
Bean Culture
•
•
•
•
Bush or pole types
Soak seed for an hour before
planting to enhance
germination
Low humidity and high
temperatures cause blossom
drop
Use bush beans for fall garden
-Short growing season (50-60
days) allows time for a crop
prior to the first freeze

Pests-Squash Bugs
http://www.ca.uky.edu
• Attack all cucurbits, squash preferred
• Eggs laid on underside leaf in
characteristic V-shape
• Adults overwinter in crop debris
• Management difficult:
-destroying eggs best
-adults will gather under boards
-vacuum up adults
-resistant squash varieties

Melon
(Cucumis melo & Citrullus lanatus)
•
•
•
•
•
Warm season,
herbaceous annual
May be determinate
or indeterminate
Melons can only
cross pollinate with
members of the
same species
Plants are monoecious
May self- or cross- pollinate

Melon Culture




Warm temps & sunny
weather produces sweet fruit
Best grown on mulch
Bees essential for good fruit
set
Only allow 1-2 fruits to
develop per watermelon
plant for best quality
Diseases-Powdery Mildew
•
•
•
•
Major disease of cucurbits
Caused by wind borne fungus
Spreads quickly in conducive conditions
Scout plants frequently, treat immediately
(sulfur, Kocide)
• Plant resistant varieties

Harvesting Melons


Harvest muskmelons
at full-slip. 30-35 days
after pollination
Observe the “ground
patch” (couche) on
watermelon to
determine when to
harvest – it will
become white to
creamy yellow
…or look at the tendril
opposite the
watermelon fruit
Melon Cultivars

Melons (other)
 ‘Casaba, Golden
Beauty’
 ‘Crenshaw, Early
Hybrid’
 ‘Honey Dew,
Venus’

Watermelon
 ‘Black Diamond’
 ‘Crimson Sweet’
 ‘Bush Sugar
Baby’
 ‘Moon & Stars’

Cool-Season Vegetables
•
•
•
•
•
Highly or somewhat frost tolerant
Seeds germinate at cool soil temperatures
Tend to have shallow root systems
Greater response to N and P application
Bolting (seed stalk development) may be a
concern
Cool-season Vegetables
• Many develop superior flavor and quality
when they mature in cooler weather (example:
broccoli)
• Flavor is improved with frost: cabbage, kale,
kohlrabi, carrots, chard, turnip
• Lettuce and spinach tend to bolt and develop
bitter flavor when maturing in hot weather
• Lettuce and spinach seed will not germinate if
soil temp is >85oF
Bolting
• Development of a seed stalk, or premature
production of seed in a vegetable crop
• Many vegetable crops become unusable after
bolting
• Triggered by:
-a cold spell (vernalization),
or
-changes in day length
(photoperiod)
Bolting
• Annual crops sensitive to photoperiod: lettuce,
radish, and spinach
-May bolt when day length increases
• Biennial crops sensitive to vernalization:
onions, leeks, carrots, beets
-Produce large storage organ during 1st year in
preparation for seed the 2nd year
-May bolt with uneven temps early in season
Bolting Prevention
• Once triggered, the bolting process can’t be
stopped
• Delay planting until temperatures are more
stable for cold-sensitive crops (ie. turnips,
Swiss chard)
• Plant in optimum window for your area
• Plant ‘bolting resistant’ varieties
Allium Family (Alliacae)
• Onions
• Garlic
• Leeks
• Monocots
Onion Culture
• Tolerant to frost or light freeze
• Shallow roots; water frequently
• Control weeds; Alliums don’t compete well
Onions (Allium cepa)
• Valued for their pungent, distinctive flavor
• Native to southern Asia
• Fleshy, basal plate main
portion consumed
• Biennial grown as
an annual crop
Onion Culture
Day length critical to bulb formation:
Short-day: require 10-11 hour days
Intermediate-day: require 11-12 hour days
Long-day: require more than 12 hour days
• Usually started as seed for fall planting
• Fall planting window, Area 1: Oct 1 -15
Onion Culture
• Harvest
– May through August
– Depends on variety
– Seed vs. transplants
• Harvest when leaves begin
to turn yellow and lodge
• Bolting may occur
with cool spring temps
-Plant resistant varieties
