Growing And Care Of Pole Green Beans
PROPAGATION / SOWING OF POLE BEANS:
Plant
pole beans 1” deep on a small mound of soil that is about 6 inches in
diameter and 3 inches tall around poles, fence, trellis, or teepees
spaced at 16” apart. Sunflowers or corn stalks can also be used for bean
supports. Plant 4-8 seeds on each hill. Space pole beans 3” apart if
growing on a fence. Sow after all danger of frost is over and the soil
is warm, 18°C (65°F). Growing pole beans gives you the advantage of
maximizing your space, and the beans grow straighter and are easier to
pick.
CARE & GROWING OF POLE BEANS:
Pole
beans prefer an area with full sun and a rich, deeply worked soil with a
pH level of 6 to 7.5. Pole beans are light feeders. The poles, teepees
or a trellis should be erected after 2-4 leaves have developed. A mulch
of compost, or straw is beneficial to control weeds and hold moisture.
Keep the plants well watered in dry weather, especially if they are
grown on an upright trellis or poles against a shed or house where soil
tends to dry out.
HARVESTING OF POLE BEANS:
Pick
young, full size pods when smooth and crisp. Harvest pole beans before
you can feel the bean seeds inside the pods. Harvest pole beans
regularly for a constant supply. Pole beans grow fast, so harvest at
least three times a week to ensure you get the tastiest pods and to
signal the plant that it needs to keep producing.
Common Problems :
 Mosaic Diseases : The bean mosaic diseases
cause plants to turn a yellowish green and produce few or no pods. The
leaves on infected plants are a mottled yellow and are usually
irregularly shaped. The only satisfactory control for these diseases is
to use mosaic-resistant bean varieties.
 Bacterial Bean Blight : Bright yellow or brown spots on the leaves or water-soaked spots on the pods are signs of bacterial bean blight.
Bacterial blight is best controlled by planting disease-free seed;
avoiding contact with wet bean plants; and removing all bean debris
from the garden.
 Rust of Bean : Most beans are susceptible to Rust. The disease occurs
sporadically and is important only under prolonged periods of warm,
moist weather. The Rust fungus exists in at least 35 pathotypes and is
extremely variable. Symptoms develop on leaves and pods as pustules of
red-brown powdery spores (urediniospores) which rupture the epidermis.
They are often surrounded by a yellow halo. Severely infected leaves
turn chlorotic, dry, and decline. Later, black to brown teliospores form
within pustules and enable the pathogen survive between crop cycles.
 Powdery Mildew :
This common bean disease thrive in both humid and dry weather. The
spores are spread by the wind to healthy plants. the fungi sap plant
nutrients , causing yellowing and sometimes death of the leaf. A severe
infection may kill the plant. Powdery mildew can spread rapidly through a
closely spaced planting.
 Bean Leaf Beetle : This
insect attacks all beans. Adults feed on the underside of leaves,
blossoms, and pods throughout the growing season. The beetles are yellow
to red with black spots and a black band around the outer edge of the
body. Both adults and grubs cause serious damage to young plant.
