Folks, I wanted to share a current experiment I'm working on to try to 
protect fruit trees from late spring frosts. I'm in NM at 7000. We 
almost never get any standard fruit because of the late frosts.

I've been trying to design and build tents that would go over the trees 
on those nights when there could be a frost after the trees have 
flowered. I've been using PVC piping and connectors to create a 
lightweight framework over the trees (they are all small trees). I'm 
working on a running power out to the fields where the trees are and 
setting up a system of 30 watt outdoor halogen spotlights so that I can 
put one in each tree tent. The tents will be covered by 6 mil plastic on 
cold nights.

We have ferocious winds here in the spring. I'm experimenting with a 
system of staking down the frames and using bungee cord to hold the 
plastic in place.

It struck me recently that there are often only one or two nights of 
frost that ruin the season's crops. On other nights the plastic would 
not be put up on the frames and so wind would not be an issue.

To make this system work I need to stick with true dwarf trees. 
Semi-dwarves would become too big to cover.

Another advantage of the frames is that it would allow me to cover 
plants with bird netting when fruits are ripe and also to shade certain 
plants that are not very tolerant of our high UV.

Anybody had any experience with what I'm trying to achieve?

Regards,

Jay
