What do you see in this picture?
Irrigation
• Large quantity of water.
• Dependable water
source.
• Overhead irrigation.
– Drip irrigation on a
smaller scale.
• Irrigation:
– Plants need water
– Cool root systems
Planting Density
• High disease pressure.
• More plants per acre.
• Higher labor cost per
acre.
• Large amount of plant
culture.
Root System Considerations
• Root system is above-ground.
• Heating of growing medium
during summer months.
• May need winter protection in
colder climates.
• Potential for the roots to
become pot-bound.
• Confined root volume.
• Frequent up-shifting to larger
container.
• Grower supplies all plant
nutrition.

Weed control
– Use herbicides with low
water solubilities.
• Transplanting
• Blow over
Weed Control
• The more water soluble the herbicide, the faster it
moves downward through the mix, and the greater
the likelihood of damaging the crop.
• Use preemergent herbicides with water solubilities
LESS than ONE ppm.
Recommended Herbicides (Whitcomb)
• Barricade, Factor (prodiamine) @ 0.013 ppm water solubility
• Goal (oxyfluorfen) @ 0.1 ppm
• Treflan (trifluralin @ 0.3 ppm
• Prowl, Pendulum, Southern WeedGrass Control (pendimethalin)@ 0.5
ppm
• Ronstar (oxadiazon) @ 0.7 ppm
• Gallery (isohexaben) @ 1.0 ppm
• Rout is a combination of Goal and Surflan
• Snapshot 80 DF is a combination of Gallery and Surflan
• Snapshot 2.5 TG is a combination of Gallery and Treflan
• Ornamental Herbicide II is a combination of Goal and Prowl
