Rose Care - June, July, and August -- It's HOT MAN!

If you are in cooler parts of Arizona, go ahead and continue fertilizing as you have. Temps in the 70’s, 80’s, and even low 90’s allow you to fertilize as regular.

*****

There are a couple of routes you can take, if you are in the HOT desert.

My Route: I stop fertilizing all together. Most roses in our extreme heat tend to go into a type of hibernation. You will notice that many of your roses are, or will, start to set hips. Much like they do in fall in cooler climates.

When your roses set hips in the fall, in the cold climates, do you fertilize? No. So why would we want to fertilize when they are setting hips in summer? If you continue to fertilize your growth will be rapid, lanky, and new growth may suffer severe sunburn. Your roses will have fewer petals, hybrid teas sometimes almost look like single petal roses.

Another Route: If you must fertilize, sometimes it’s hard not to, I know, always fertilize at half the strength you do during the cooler months. Or, another great way is to use time released fertilizer, like Osmocote. I prefer the Osmocote 14-14-14 time release fertilizer. I do use it in my potted roses all summer long, because it’s released slower, and fertilizes every time I water, without hurting the roses.

*****

Do, water. Roses are thirsty, and need water. You can’t water them too much in the summer. I have one bed of roses in the front yard that surrounds my entire front yard. In this rose bed, I use bubblers, because of all the other perennials and bulbs that are in that bed. I water once a week, and fill that bed with water.

The rest of my roses are drip irrigated. I use drip nozzles you can adjust up to 10 gallons an hour. In the summer, with drip irrigation, I water my roses three times a week (Monday, Wednesday, and Saturday), and they get 4 gallons of water, each watering. That takes me about 3 hours per watering.

How can you tell how fast your drip lines are watering? Take one of your nozzles and stick it into a gallon jug. See how long it takes to fill the gallon jug ½ way full. If it takes 15 minutes to fill it with a ½ gallon of water, it will take 30 minutes to fill the gallon jug, and 2 hours for 4 gallons of water.

If you have roses in pots, they must be watered 7 times a week, depending on the location, maybe even twice a day. I don't recommend pots in full sun in our desert. It's just too, too HOT!

*****

Keep your roots cool. Mulch, mulch, mulch those roses, with a deep layer of mulch over your top soil to keep the rose roots cool. Your roses will thank you for it. I put about 4 inches of mulch over the top of my rose beds every other year.

When I die and come back, Alan, I want to be a Rose in your garden!

Now what did you mean to say here? "If you have roses in pots, they must be watered 7 times a day, depending on the location, maybe even twice a day."

Oh, what a relief! I only have one rose in a container - a half barrel. It has not done well there but I don't want to put it in the ground in case we move. Can I do something to make it happier?

Water it and use a time released fertilizer would be my recommendation. Put it where it will be in the shade during the hottest part of the day. Water it daily now that we are reaching the triple digits!

Thank you for the information!! I was wondering how much to water my roses this summer. I also need to check the mulch level! Great reminders!

Alan, why is the banner of prickly pears and not roses? I just noticed that, believe it or not. Confused

Because the banner is the header for all of this forum. It doesn't change for each forum. We are hoping to create a collage eventually!

Alan, I think the thumbnail for the rose Forum her is too far away. Do you have a favorite close up I can substitute?

Sorry.

When you go to the Arizona Gardens home page, you'll see I placed a thumbnail (mini photo) that gives an idea as to what is in each forum.

I used one of your Sunsprite bush. But I realize a close up of one pretty rose would be a better image. Once you send one...even right here, I can copy and replace that image.

If I put shade over my roses, will they not get crisp and brown?

Are you talking about the blooms or the whole bush. Shade always helps, but you don't want your roses shaded all day or they won't bloom as well. Long term you might plant a shade tree on the west side of the tree to provide dappled shade in the afternoon.

The bushes look a bit stressed but it's the blooms that really suffer. As soon as they start to open, they start to curl around the edges and get an ugly brown.

I have a forest of sunflowers on the west side that shades the closest ones. I was thinking of putting up some poles and using 50% white shadecloth. It may not be worth the trouble though.
