Anyone use growth regulators for hedges (mostly privet).
If so, please share your experience, with brand, and how and when to apply and how often.
I never used it before and was wondering if they work

They work. Try attrimec (gordon's product).

They work very well. Read the label carefully.

We've used them on Russian Olives and had pretty good results, spray till drip with them. Whips still began to erupt, but still significantly reduce trimming time.

I have a condo complex with a lot of hedges at must cut them at least ten times through out the season which is very time consuming. If the growth regulator is used hw many times would they need to be trimmed?

Cutless Granular can be used for this purpose and has shown to control growth for 3-6 months depending on rate, species, etc.

Thanks guys. Is it pricey?

Yes it's pretty expensive. If you consider the labor, gas and removal it's more than worth it. On Russian Olives you trim first then apply and from that point you trim only some of the small shoots that emerge and try not to ever cut away the layer that had the spray. Read the Atrimmec label from Gordon.
Applied correctly and you'll love it. Good Luck

I was just thinking about this the other day. I like the idea of pgr's however I just took over an account with hedges that looked to be treated with pgr's by the fact that there wasn't any new growth and spider webs like crazy. to me the hedges looked terrible. is this typical when using pgr's?

Nope it's not, more typical of a shrub that's been over sheered. Plants that I have seen which have been treated with PGR's are typically denser than normal.

when should I apply? this might already been covered

cutless all the way.
We get the most repeat sales on Cutless at our lesco store. get it out 3-4 weeks before the shrubs start growing.

rate depends on shrub size but 4-5 lbs/1000 is average

I used to see that alot with Podocarpus when they were trimmed after every 1/4" of new growth :). I would usually try to thin them out a little bit with hand pruners to start letting some more light inside. The extra light seems to reduce the spiders and also encourages more interior sprouting. Also letting the plant grow a little bit more in between trimmings helps.

We have always used Daminozide (B9) and I have to say it works and once it is flushed through the soil the plant growth starts back up like nothing was ever applied.
