FAQ Rose Gardening Questions

Below are the most FAQ rose questions with answers about growing roses and rose problems, that gardeners, like yourself, can encounter when doing rose gardening.

The questions are compiled from the American Rose Society's records of the most frequently asked questions about rose problems and gardening with roses.

Keep in mind how heavily your roses bloom also has to do with weather, water, pruning, fertilizing and sun-light.

Roses don't like to flower in hot weather.

That means repeated days with temperatures above 85F/30C.

They also bloom as long as they have a steady moisture.

In times of drought they conserve moisture in any way they can, and one of those is to stop blooming.

Pruning aslo comes into play. Pruning correctly encourages repeat-blooming roses to flower with abundance.

Deadheading to remove spent flowers will prevent seed formation that will stop the blooming.

Flowering Rose Questions

If your roses aren't flowering well, another reason is lack of enough sunlight.

Roses love sun and it's hard to give them too much.

You might have to move a rose to a spot with a lot more sunshine in your garden, or remove branches of nearby trees that cast shade.

Another possibility for roses not flowering well, is that the rose plant is starved for nutrients.

Roses are heavy feeders. Even if your roses bloom without rose food, you'll be surprised at how much better they will bloom if you fertilize your roses regularly. Even as often as every 2 weeks.

Rose Questions

When To Prune?

You can cut out any dead and diseased wood (looks black or gray) any time.

But roses need a major pruning in late winter or early spring, when they first come out of dormancy. Check for swelling buds on the canes.

Yellow Leaves on Roses

Examine the undersides of the foilage for disease or pests such as spider mites.

If you don't see any you need to do a soil test to find out the pH value of your soil.

In alkaline (high pH) soils, iron is less available for plants. Lack of iron usually results in yellowing foilage and poor plant growth.

Holes on Rose Leaves-Rose Questions

They are usually caused by rose slugs. They make themselves apparent by leaving behind leaves that are eaten between the veins.

Rose slugs are green sluglike worms up to 3/4 inch long with brown heads.

If there is little damage and you can spot them, simply pick them off by hand and discard the slugs.

For more severe infestations, you can spray with an insecticide containing "acephate" or "carbaryl". Repeat as directed on the package.

Rose Changes Flower Color

Some grafted rose bushes start changing flower colors after a couple of years.

The rose is a grafted rose that was created by using two parent roses.

For some reason, the graft wasn't successful, so the rose is now reverting back to one of its parents.

Sorry, but there is nothing that can be done about it. These roses will not go back to the color it was when you bought it. I have never heard of that happen. It's not common, but it does happen.

What's Wrong With My Roses?

If you can't spot any garden pests or rose diseases, I reommend you find out the pH of your soil.

The real importance of soil pH is that it has a major effect on how well certain crucial nutrients can be taken up by the plant.

Why Won't My Climbing Roses Bloom?

Older, once-blooming climbing roses only bloom on old wood.

That is canes that that are two years old, or older. So if you prune those kinds of climbers in spring, you'll never see any flowers.

Many repeat-flowering climbers (these should be pruned in spring) take a couple of years to bloom, because they spend all their energy growing long arching canes from where the shorter flowering shoots will grow.

Meaning they don't have any energy for flower production for the first couple of years.

Why Do My Rose Leaves Turn Yellow and Fall Off?

Check the undersides of the leaves for spider mites. You might need to use a magnifying glass.

If you see the little spiders, they are busy sucking the life from your rose plant.

Take a garden nozzle and blast them off your rose bush. Be sure to do the undersides where they hide.

Then try to spray with summer oil which smothers the little spider mites suckers.

If you don't see any spider mites, check my page about rose diseases to see if your plant has black spot or any other fungal disease.

What Are The Easiest Roses To Grow?

Bareroot or Potted Roses? Rose Questions

The difference is, potted roses have their roots growing in a pot of soil, and the bareroot rose has all the soil removed from its roots.

Bare-root roses are sold this way when they are dormant very early in the season and arrive this way via mail-order.

Whenever possible, when buying potted roses, or container roses, choose the ones that are not in bloom, so that once planted they can focus all their energy growing feeder roots and getting established.

Why Are My Rose Leaves Covered With a White Powder and Shriveled?

Your roses have powdery mildew. It's a fungus disease.

Remove severly infected leaves. Spray with summer oil, or with a baking soda mixture.

Why Aren't My Roses Fragrant?

Some rose varieties have little, or no fragrance at all. And some roses that are supposed to be fragrant, might not be fragrant in certain climates or under different soil conditions.

The scent of a rose depends on how mature the rose bush is, the time of the day, and weather conditions.

The rose flowers are the most fragrant when they are three-quarters open in the early afternoon, on a calm day with relatively high humidity, and temperatures over 70 degrees F.

Also roses are the most fragrant when temperatures are warm but not scalding. Excessive heat or very cool temperatures make their scent harder to detect.

This means that in warm climates, roses are most fragrant in the morning, or evening.

In cold climates, roses are most fragrant late afternoon when the day is the warmest.

This tip was provided by the American Rose Society, which I am a member of.

When Should I Start Winterizing My Roses?

This is one of the most important rose questions that gardeners want answers to. Wait until you see your roses going dormant.

But you definitely don't want to do it when it's snowing, or in the snow.

Where the average annual minimum temperatures are 5 degrees F (-15C) and below, late November, which is Thanksgiving Weekend in the US, that's a good time to start winterizing your roses.
