A trick for encouraging growth in iris

-
It's the second week of December here at The Tropical Paradise in Glendale, Arizona, and if you planted iris in September or October, you should be seeing some strong growth by now. Don't worry, they won't bloom until February, but they will do a lot of growing in the next couple of months. And you can encourage growth, and ultimate bloom with a simple trick, simply scraping away the soil at the base.

I just use my fingers and scrape away some of the leaf litter, rocks and any other stuff that is around the base of each plant. Yes, it's OK if you can actually see the top of the bulb. When you do the scraping, you make a little swale that will hold water better. Get a large watering can with some plant food mixed in (I use Miracle Grow, but they're all the same) and water. Then do it again, and again. Iris love water, and for some strange reason, they do better with their roots exposed. I don't know why, but they do. Iris that are planted too deep don't do as well. I found this out by accident, because, well, I got sloppy one time in my planting.

One of the really nice things about iris is their beautiful, tropical foliage. And the foliage will grow like crazy during the winter months. Remember that iris is just a large flowering grass, so treat it like grass. Give it water and fertilizer and stand back and watch it grow. When the weather starts to warm up, it will bloom. Once its finished blooming, it will start to die back. When the weather cools down again, with water, it will return.

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...
