I agree with Jil that the screen frame is a great idea. What
size mesh do you recommend for Ficaria verna and what size for
Arum italicum? You should go into business -- I would definitely
buy one of each from you.<br>
<br>
BTW, I was just trying to convince a neighbor on Saturday to get
rid of the A. italicum she'd planted on her property, but she
didn't want to hear what I was saying. She said it was filling a
bare slope that was eroding. And, she's even helped with a
native plant symposium for ~30 years, and noted that it was
spreading to another person's yard. In addition, I had just
warned another neighbor in February about the Italian arum that
his landscaper had planted for him in 2020. I'm wondering
whether this difficult-to-eradicate invasive is becoming
increasingly popular.<br>

recommend building a screening frame with the proper

<p class="MsoNormal"><span style="font-size:12pt">That
plant is a monster. Italian arum is or was at the
national arboretum (that's where I first got to
know it about a decade ago). It's very hard to get
rid of. It's best to dig plants up - you have to
get ALL the underground tubers and bag and dispose
of the material in a landfill. You could leave it
in the bags for a while to let it rot before
disposal. It would be best to remove most of the
soil in the area where the plants are, if that's a
possibility. That would help ensure removal of all
tubers.</span></p>
