Tom's workshop notes, Saturday, March 09, 2019
Wow, did I learn a ton of stuff at the High Tunnel workshop. The speakers were from University of Utah and have a very similar growing climate. Here is one of their fact sheets on tomatoes.
Here are some take a ways.
· Best tunnel temp range 45-90 F
· Test greenhouse soil
· Must track temp and soil moisture
· They are using heat tape in the soil to push crops earlier
· We are not getting tomatoes plants in the greenhouse early enough
· Three keys to successful tunnel tomatoes
o Plant in plastic mulch
o Low tunnel hoops of plastic or row cover inside high tunnel
o Shade cloth in summer
· To Minimize plant and insect issues
o Add organic material
o Maintain soil fertility
o Discard all greenhouse plant material (don't compost for reuse)
o Monitor insect populations
· We are letting our greenhouse temperatures get above 90 F
o Heat stress for plants and growth slows
o Sun damage to fruit
