Adding a new sprayer head to the watering system

-
Plants grow well here in the Phoenix, Arizona area, but it gets REALLY hot in the summer, so water is critical. I just added a new sprayer head for the watering system yesterday and am doing a bit of refining this morning. The goal is, of course, to water the plants, not the walls, or the sidewalks.

This is a typical low-pressure *drip system*. The 1/2-inch trunk line runs all the way around the garden, towards the back, and is buried in the gravel just a few inches down. So, if I need to add a new sprayer, I can get to the trunk line easily, insert the new sprayer head, and then push the gravel back in place.

This is an adjustable sprayer, and it looks like it's doing fine. As you can see, the idea is to keep the area along the wall dry, and not have the spray hitting the sidewalk. Well, there are a few drops, but that's OK. This is all ordinary, do-it-yourself stuff from Home Depot, by the way.

I planted a lot of small stuff here, but mostly I am interested in getting the cannas (at left) growing back strongly into this area. Water makes all the difference here in the desert!

How to tell if your cycad (sago palm) is alive or dead

-

Cycads are strange plants. They're beautiful, and look like small palm trees, or large ferns. They grow very slowly, and can be very expensive, even common ones like "sago palms". But sago palms, in spite of their common name, aren't palms at all. They belong to a group of plants called cycads. They are wonderfully weird, and grow in strange ways. And sometimes they lose all of their leaves. Of course, if it were a palm tree that lost all of its leaves, you would know that the plant was dead. But it's not true of cycads. So don't dig that cycad up and throw it away! Not yet. If you've recently transplanted a cycad, and the leaves have all faded away, hang on. Take a look at the top center of the plant, at what I call "the pucker". There you will see some stubby, soft fronds, no more than an half-inch or so. At least that's what you should see. That means that the plant is still alive, and has dropped its leaves to focus on building r...

Rooting sago palm pups for more plants

-

Once a sago palm ( cycas revoluta ) reaches a certain level of maturity, it starts to create pups. Like agaves, these are little plants that are exactly the same as the parent plant, only smaller. And yes, you can trim them off and grow them into new plants. This is how to do it. Cut them off from the parent plant with a sharp knife. If there are any roots at the bottom, try to save them, but chances are there won't be any. That's not a problem. The next step is rooting them. Douse the cut part and the bottom of the plant with some garden sulfur and some rooting hormone powder. Rooting hormone powder is pretty easy to find at your local Home Depot. I had to go to a real nursery to get garden sulfur. Anyway, the idea is to keep the little plant from rotting while giving it time to grow its own roots. Sago palm pups being rooted Bury them fairly deep in some free-draining mix. It should include volcanic pumice, if you can find it, and if not, you can use perlite. I ...

Growing sunflowers from Pennsylvania in Arizona

-

It's October 21st, and I just received some sunflower seeds from a friend in Pennsylvania. Their season is ending and the season for planting here in Arizona is just beginning, and I'm kinda wondering if the seeds are wondering what's going on? It's spring again already? If you're new to the Phoenix, Arizona area, and are from back east it must seem kinda strange that fall and winter is our flower season, but it is. By springtime it will start to get so hot here that the flowers will die, and of course back east the season is just beginning.  Sunflowers growing in Peoria, Arizona, about a mile from where I live I've seen sunflowers blooming around my neighborhood of Glendale, which is a suburb of Phoenix, in the winter, and although I've never grown them I understand that they're easy to grow. I guess I'll find out - I learn best by doing! The seeds arrived safely, and it's my understanding that they were still connected to the spent flower (I do...
