Roses

rosesRoses are giving spectacular blooms this year. You might not know it, but Arizona is one of the rose-growing capitals of the country — they grow really well here.

Now is not the time to start pruning roses, but there are a few things you can do to help your established plants or newly planted roses and make sure they continue to give you beautiful blooms.

Watering

Water deeply (about 2 to 3 feet deep) to leach away salts.

Water every four to seven days, depending on your type of soil.

Care

For vine or climbing roses, force blooms by bending canes horizontally and attaching to a tree, trellis or porch.

Don’t prune until January or February.

To cut flowers: Cut just above a set of five leaves; cut at a 45-degree angle; seal cuts with lipstick or white glue. Immediately place cut roses into cool water. To keep flowers fresh, add 1 tablespoon of vinegar to the vase of water.

Fertilizing

Use only organic fertilizers.

Place a 4-inch layer of compost around the bush.

Every two weeks, add fish emulsion or liquid seaweed to the soil. Alternatively, you can make your own soil additive by combining 1 cup gypsum, 1 cup bone meal, 1 cup blood meal, 1/2 cup sulfur, 2 tablespoons chealated iron and 1 tablespoon epsom salts. If you make your own mixture, add 2-1/2 cups to established plants and 1 cup on new bushes.

Protecting

Roses have two main enemies — aphids and powdery mildew. To keep these nasty little guys away, always plant garlic and onions next to your rose bushes. Additionally, aphids hate plants like Artemisia and Nasturtium.

What to do if you see aphids: hose off your plant, then spritz plant with a mixture of 1 tablespoon cooking oil, 1 gallon water and 2 tablespoons blue dishwashing liquid.

If you see powdery mildew, power wash your plant before 9 a.m., then let the sun dry the leaves. (Wetness promotes mildew.) Additionally, you can combine 1/3 cup baking soda, 12 ounces water and a squirt of blue dishwashing liquid and spritz your plant periodically. That should keep the little buggers away.

    Hi, I was wondering if you can tell me where is the best place to plant my roses. Direct sunlight or morning sun only, etc. Thank you.

      Hi Shari,

      Roses do need full sun, you could add some shade but direct sun light is best for them!

    My rose gets full sun light , I used a shade that sun could get thru but it seems like now most of it leaves are gone and it crispy , I water daily or every other day and use mulch also . Is my rose dying ?

    Dave. My rose bush is in full bloom. Is it still ok to trim it?

    Hi Dave,
    Ineed help in identifying a tree like plant that sprouted up two years ago and now looks like a small tree. There are no discernible branches but the leaves look kind of heart shaped and clover shaped as well.
    Let me try that again. the leaves are more in the shape of a clover but looks like a heart for each clover part.

    Do you have any idea what this tree might be. Several years ago (5) I did buy some green tea seeds from some place in CA and planted them among my berries. Low and behold 3 years later I get this tree. Do you think it might be a green tea tree? If there is a way to send a picture I will. Let me know.

    Thanks for your help.
    Becky

    Tell me if I should pull it up and start all over please! I live in Globe, planted a climbing rose bush THEN discovered what I thought was a secure area isn’t & Javelina stripped the bush, including most of the bark. Am guessing it’s a goner in the long run…but just in case, can it regrow bark?

  7. Brittany says:

    What time of year is best to plant rose bushes? Do tea roses need to be planted at a different time than climbing roses? How should I prep the soil for planting?

    • The Garden Guy says:

      Hi Brittany,

      Fall would be the best time to plant roses and all the same between climbing and tea roses, if you try it now with the way the temps are increasing you run the risk of them not making it with the summer heat.

  8. Barb says:

    Hello Dave, my roses just went through a large batch of blooms, but now my bushes have the dead blooms on these, can I trim those back? Will the trim, help promote another set of blooms?

    Thank you!

    • The Garden Guy says:

      Hi Barb,

      Yes you can remove the blooms, you should be able to pull them off very easily for the new set!

  9. Murphey says:

    How long do you leave your roses covered after tenting them from the scorching sun?

    Days,or until the heat subsides?

    Thanks

    • The Garden Guy says:

      Hi Murphey,

      If you are using shade cloth you can leave it on all summer anything thicker you want to cut back on

    Hi Dave,
    Can you help me out? The leaves on my roses are turning brown and falling off. I give them rose food about once a month and they get water every other day for 42 min. The drips are 2 gallon drips. and the roses are in full sun. Thanks in advance!

    • The Garden Guy says:

      Hi Cindy,

      I would add some compost around the base and possibly some shade cloth seems like it might be just heat getting to them as everything you are doing seems fine

    Hi dave. My new roses have yellow leaves with black spots on them. Too much water. Also my rose tree was covered with what looked liked spider webs, and the leaves turned a rusty color. What bug did this?

    • The Garden Guy says:

      Hi Debbie,

      The first part is correct about too much water on the roses with yellow leaves. As far as the spider webs and rust it could be 2 things spider mites or a fungus to treat the spider mites you can use liquid seaweed/Extreme Juice to spray it and help clean it off and if it is rust make sure there is proper air flow for the roses and make sure to collect any fallen leaves to prevent it from spreading. Make sure to not over water and they have proper drainage
