SIB: Patti Wenham

Hi Patti,	
	Siberians are wonderful plants once you get them through the first year. They 
form tight grassy clumps that bloom forever. They never really need dividing 
to keep them blooming unlike the bearded varieties. However, after several 
years, dividing them is a chore, especially on those tetraploid varieties. I 
find a back hoe and dynamite very useful for this.
	I don't have much trouble getting them through the first year but I live in 
Seattle (zone 8), pretty mild compared to where you live. I mulch mine over 
winter and remove mulch after the last frost (sometime mid-April). I keep the 
ground moist all year (water once a week if we haven't had rain in a while) 
and fertilize with acid fertilizer once a month. If you are very dry and hot 
during the summer months you may want to consider mulch all year to keep the 
ground moist.
