6 Reasons Why Roses Are Not Blooming?

6 Reasons Why Roses Are Not Blooming?

There are many varietals of roses. There are tiny hybrid roses that are smaller than half a dollar.

In addition, there are colossal rose blooms that can measure over half a foot across. Your rose bush is just another green plant without its flowers.

If you overfertilize your rose bushes, they may not bloom. However, overfertilization of your plants is not the only reason that your rose bush is not blooming.

Depending on the variety of rose you have, it may not bloom but once a year.

Older types tend to bloom in the spring and fall, while newer roses can bloom off and on throughout the growing season.

Let us read on and examine the reasons that your roses are not blooming.


Why are my roses not blooming?

Roses may not bloom if it isn’t their season yet to do so. Overfertilization can also curtail blooming, just as applying too little will. Other reasons are too little sunshine, not pruning your bushes and pests.


Reasons why roses aren’t blooming


Inappropriate soil

Getting your soil tested once a year is a good gardening practice. Your local agricultural extension office can do this for you.

The test will then tell you the components, particularly the nutrients and pH level, of your soil. You can then add nutrients, or if necessary, reduce them.


Fertilizer abuse

Many people fertilize their roses just because they think they are supposed to.

However, overfertilization or fertilizing too seldom can lead to a rose bush that will not produce blooms. Conversely, under fertilization can also lead to bushes that do not bloom.

On the other hand, poor soil that is rocky or sandy can be amended to sustain the growth of your rose bushes.

If you are planting new plants in poor soil, be sure to add organic matter so that the soil can retain water.

When nitrogen builds up in the soil from applying too much fertilizer, it is time to pare back, and the soil test you have done will help you when asking why are my roses not blooming.

Some fertilizers are formulated just for your rose bushes. Using such a product can help you keep your rose plants healthy, happy, and covered with blooms.

As heavy feeders, rose bushes have unique nutritional needs.

Most fertilizers use a mix of nitrogen, potassium, and phosphorus at a blend of 10-10-10 or 20-20-20. Not roses, though!

They have a thirst for potassium, but you do not need special fertilizer to add this mineral.

Instead, by working aged, organic material around your plants, you can add the nutrients they need.

You have options when it comes to fertilizing all of your plants.

Commercial fertilizer over organic products is personal, and both work well for growing healthy rose bushes.


Inappropriate planting location

The location of your roses may be the problem. However, it doesn’t mean that if they bloomed in that particular location previously, there won’t be any problems with their blooming later on.

Look around you. Is that elm taller this year? Is your neighbor’s new garage blocking the sunlight your plant had last year?

If that’s the case, plant your rose bush in another location.

Roses like sunshine, and if they are not getting enough, you will have more of a problem than a plant that is not blooming, as they will not be as healthy.

Plants that are not healthy are prone to disease and pest infestations.



Where you live and the amount of local rain you receive are determining factors in how often you need to water your roses. Also, the type of soil you have may hold water or drain quickly.

Roses prefer well-drained, nutrient-rich soil. Unfortunately, drainage is not always considered when setting plants in the ground, and roses underwatered can become stressed.

In addition, roses can be significantly affected when the temperatures exceed the 90 degree-Fahrenheit mark.

Excessive heat can dry the air and the ground more rapidly, depriving your rose bushes of necessary moisture. Moisture meters help you determine if you need to water your roses more or less.

Misting your roses will help them recover from the stress of heat, but do this in the morning so that they will have time to dry before nightfall.

Plants that go to bed wet are susceptible to fungus.


Pests that love your roses

Aphids love the sweet smell of roses. But, they will devastate your bushes if you do not catch them in time. These little green pests will eat the blooms before they form.

Plants that are getting too much nitrogen can become weak, which makes them easy targets for aphids.

These tiny insects live off the plant’s sap, and an ailing plant offers more accessible access to the sap due to weakened plant tissue.

Most gardens host a few aphids, but if they find a weak host, look out! They will grow exponentially and eat every bloom your rose is trying to produce.

A good countermeasure is ladybugs. They love aphids as much as aphids love your roses.

A visual inspection of your plants will let you know if this is your problem. If you see a few of these insects, a blast from your water hose will remove them.

However, if there are more than a few, an application of soap and water, neem oil, or spraying with an essential oil mix will rid you of larger populations.


Improper pruning

Pruning your rose bush at least once a year will stimulate its growth. Failure to do so can lead to long, leggy branches that produce fewer flowers every year.

After it has bloomed, deadheading your rose bush is also a recommended practice that will help your rose bush bloom more prolifically.


Frequently asked questions about why are my roses not blooming


When should my roses bloom?

That depends on the variety of roses you have. Newer types tend to bloom for the entire season while climbing, and older varieties may only bloom in the spring and fall. The time between blooming for newer varieties is 28 to 70 days.


Is my rose bush dead if they do not bloom?

It’s possible, but, it can also be that your rose’s growth was stunted by a hard winter. Your rose bush may produce leaves come spring but not be strong enough to produce blooms.
