LESSON 5.58 BLUEBERRIES – GROWING IN BAGS
Two Techniques for Growing Blueberries Option 2: Growing in Bags
Growing in grow bags is a method of blueberry production in greenhouses and tunnels.
Although the growing method is
difficult, it is often chosen to provide optimum growing conditions including
low pH and adequate drainage.
If growing in bags, there are
a number of important considerations to take into account as you set up your
system:
Greater
Sensitivity
Growing in bags means a
smaller margin of error than growing in soil. The grow bags have less
nutrients, and therefore you need to carefully prescribe the exact nutrient
application that needs to be delivered through the drip irrigation system
Bag
Sizes
Growing in bags may require
progressively larger bags over time.
Do
not confuse Soilless/Hydroponic pH and Soil pH
Blueberries require a pH of
4.5 – 5.0 while the optimal solution for nutrients is between pH of 5.5 – 6.0.
If the nutrient solution or growing medium is too alkaline or acidic, many of
the nutrients will be lost.
Additional
Sulfur Requirements
Blueberry plants use higher
amounts of sulfur when compared to many other plants. Blueberries require more
than standard formula of sulfur to be added.
Irrigation
Methods
There are two common drip irrigation methods used for irrigation in grow bags.
Product Spotlights
We features a number of drip irrigation solutions to help you grow the
highest quality, highest yield blueberry crops. From drip line to drippers, we
have a solution no matter your terrain or field challenge.
D5000 AS and HydroPCND Drip Line
D5000 AS and HydroPCND provide
the ideal solution for in soil and drip line over grow bag applications.
D5000 AS
·
Ideal for flat ground and sloping ground.
·
Anti-siphon (AS) mechanism reduces the speed of drainage during shut-down.
This is important for blueberries to help prevent water logging at system shut
down.
HydroPCN
Water is sealed in the drip line when the pressure drops below 1.0 meter.
· The no-drain feature makes HydroPCND the ideal drip line for pulse
irrigation as the water remains in the tube
Drip
line over bags
A PCND (pressure compensated
no-drain)
Drip
Line is laid over the top of the grow bags
Online Drippers with tube and pegs
Polytube runs the length of
the greenhouse.
Online drippers are inserted
into the tube.
Each
dripper has a tube leading to a peg that is inserted into the grow bag
