| Young Joshua tree in desert landscape |
A. I tried to think of reasons why this person would tell
you this and I cannot think of any.
I don't agree. These are very good choices close to a
pool area. What is nice about plants such as these is that you can direct their
root system with the location of your water supply. I suppose there could be
cracks in the pool that would allow for leaks.
However, most plants go after
water which is the cleanest. If you apply drip irrigation to the sides of the
plants away from the pool this will encourage their roots to grow in this
direction.
Pool water is not good water for most plants and if they
have a chance to take up better water they will. So keep your drip emitters or
your sources of clean water on the side of the plants away from the pool. These
types of plants survive on infrequent rain water so their roots are typically
shallow and very efficient at scavenging for water close to the soil surface.

Water them with shallow irrigations, perhaps no more than
a foot deep and don't do it very often. In Midsummer if you want to encourage
growth water them every two to four weeks. If you want them to slow down, water
them less often. Watch carefully for agave weevil attacking and killing
primarily agaves and in particular American agave. I have posted information on
their control in this blog. You can search for it by entering agave weevil in
the search box.
I wonder if its a distant ancestor of the cactus? It looks like an invasive tree, though doing no harm. I like it.

I just wanted to comment that we put up an above ground pool right next to a large joshua tree when we lived in Hesperia, California, and the tree was always dropping debris into our pool, so we had to clean the pool water more often than we would have had to otherwise. So in my opinion while other agaves might be ok near a pool, I personally don't think a joshua tree is a good idea. Posted by Xtremehort for Patti
