Junipers? Any that do not develop rust?

3 years ago

I'd really like to try another Juniper. I had 'Skyrocket' and it got rust bad and I removed it. Anyone aware of a variety that is rust free?

Not try to hijack, but I’m planting some Blue Point junipers , for their vertical interest, drought & deer tolerance , ok height near power lines.

But did not actually consider rust issues.

It’s hard to “ try one and see” because I get them on the smaller side so I can plant them, & then slow growth plus have to water until established , so I was grabbing one here & there when they turn up at right size/ prices.

Also have paces where Nana seems happy, but may be too soon to tell. Not a fan of Blue Rug, I think because planting conditions don’t support them ever becoming a lush groundcover, plus, … acorns.

There are juniper species that are rust resistant (J. ashei, J. chinensis, J. conferta, J. rigida, J. sabina, J. squamata). And there are also a few resistant cultivars of some species that are considered susceptible but it takes some digging to suss them all out.

Much depends on the juniper form you are looking for. Columnar, tree-like forms like Skyrocket that are rust resistant are harder to find than the lower growing, spreading types.

FWIW, resistant does not mean immune!

in my MI.. rust wasnt as much of a problem as juniper tip blight...

at about 7 to 10 years.. i just got rid of all my blue junipers due to such.. and that alleviated the problem.. lol ...

i dont remember which type of Js they were

also.. they were horrible with snow load and ice damage.. worse even that arb splaying due to such ...

imo.;. you should be able to do so much better.. especially if you skip big box.. and pay a bit more for a great specimen ...of ANYTHING else ...

just btw.. and fyi ... juniper are trees.. which are also conifers ... and unfortunately commonly called shrubs.. just like all the flowering shrubs which arent trees nor conifers ...

hows that for a compound sentence.. lol ..

A completely inaccurate one! Not all conifers are trees, which describes only the growth habit of the plant. This as been clarified countless times. So you can encounter conifers that are shrubs and groundcovers. And shrubs do not have to produce flowers to be shrubs - no one would ever consider a Pfitzer or Blue Rug juniper as a "tree"!!

Well, thank you for that additional information Ken. I'm just starting to think through a new project of trying to grow a living screen along one lot line. I wanted a mixed grouping and lots of limitations on what I can use there. I like the look of Junipers but really I've already had one that didn't work out and I don't really think I have enough sun there for most evergreens at all, anyway.

I'm starting to look at broadleaf like Rhododendrons. Or a few trees if I can find something that I like that is narrow and that maxes out below 20ft and flowers and berries. [g]

I should have the winter to plan it out and decide what to use.
