Q. I have a cactus garden that faces west. Every summer I
hang sheets on a clothes line in front of the cactus because it always looks
like they are starting to burn up from the direct sun and heat. If I don’t protect the cactus this year, will
they die?

A. It’s difficult to say without knowing which cacti you
have. Not all cacti are the same and handle the Mojave Desert with ease. Cacti
available from retailers are from a wide range of habitats. Some of these
habitats are not as environmentally extreme as our own Mojave Desert.

These
cacti may show signs of stress when plunged into our Mojave Desert climate and
soils. Cacti that originate from other areas may be more tender to Mojave
Desert conditions. Discover which cacti you have and their place of origin.

| Although not a cactus, this yucca is native to the dry sand dunes of the southeastern US and is damaged by the intense sunlight of the Mojave Desert if planted in the wrong location in a landscape. Yucca is oftentimes grouped with cacti. |
Of
course, cacti native to the Mojave Desert have a much better chance of survival
without protection than cacti imported from other deserts with a milder climate.
I would recommend using these if available.
You might have to relocate some of your
more temperamental cacti into a milder microclimate in your landscape. Find an
exposure on the east side of the home or under some light shade. Most cacti can
be relocated during the heat of the summer months.
