How To Deadhead & Fertilize Rose Bushes – The Secrets To Keep Your Roses Blooming!

If you are looking to keep your rose bushes healthy, strong and blooming this summer – the answer all comes down to learning how and when to deadhead and fertilize your rose bushes on a regular basis!

Rose plants are extremely heavy feeders from the soil. Not only do they use a lot of energy to produce their stunning and fragrant blooms, they also need it to produce new foliage throughout the growing season. And once they produce that foliage – even more to keep it healthy and vibrant.

All too often, by the middle of summer, roses begin to fade with little notice. Not only does their foliage start to weaken, there blooming cycles diminish as well. Unfortunately, beyond looking unsightly, it also leaves rose bushes more susceptible to disease and pests as well.

With proper fertilizing and deadheading – you can keep your roses blooming strong all summer.

In addition, trouble can start to occur below the surface of the soil as well. Without enough nutrients, root systems weaken, which can then make them much more prone to issues when winter and freezing temperatures arrive. 

The good news? By simply fertilizing your roses throughout the summer – and taking care of old blooms as they fade – you can not only keep your roses healthy and full of life, but also give them the best chance of producing more rose blooms than ever!

How To Deadhead & Fertilize Rose Bushes

Deadheading Old Rose Blooms

The term “deadheading” refers to the process of trimming or cutting spent or dead blooms off of plants. Most all flowering plants, whether they are annuals or perennials benefit from this simple chore. 

Even though the fading blooms are dying, they still continue to use up valuable resources and energy from the plant and soil. But when you remove the blooms, the plant is able to instead refocus its energy on producing more shoots, stems, and blooms.

Deadheading is especially important for rose varieties that continually produce blooms throughout the summer months. This includes climbing roses and everblooming roses. Even the ever popular Knock Out rose varieties still benefit from deadheading.

Deadheading roses isn’t difficult or time consuming. In fact, by simply performing the chore once a week throughout the season, you can more than keep the energy flowing for new blooms.

To deadhead, use a pair of sharp scissors or garden shears to clip the stem of the spent bloom off. It’s important to take a few inches of the stem so that three or four of the leaf segments are removed as well. Affiliate Product Link: 8″ Professional Premium Titanium Bypass Pruning Shears

One final note on deadheading, always be sure to sanitize your cutting tools between roses. If there is disease present, it will keep it from spreading to the next bush from the blades on your pruner. To sanitize, simply wipe down with a bleach wipe.

Now on to the second big task – fertilizing!

Fertilizing Roses – How To Deadhead & Fertilize Rose Bushes

As mentioned earlier, roses are heavy feeders and will quickly deplete all of the nutrients and resources in the soil by the time mid-summer arrives. If the soil doesn’t get replenished, your plants will slow growth. They may even stop producing blooms altogether. 

That’s where a timely dose of fertilizer comes into play. But as for how often to power your roses, that will all depend on the type of rose you are growing.

For roses that are growing in pots or containers, they will need to be fertilized more often. This is because they only have a small amount of growing medium and resources and they can quickly be depleted from the soil.

Tea roses, Grandiflora, and miniatures roses will also need more frequent doses as well since they continually put on blooms. More mature shrubs and climbing roses, however, will require less fertilizer during the summer. 

Types of Fertilizers – How To Deadhead & Fertilize Rose Bushes

There are many different types of commercial fertilizers on the market nowadays, but you can also use organic products like worm castings and compost to create your own fertilizer if you desire. Both can work equally well.

All fertilizers will provide plants with a certain amount of nitrogen, phosphorus, and potassium (shown as N-P-K on packages). However, roses also benefit from additional doses of manganese, calcium, sulfur, copper, and other micro-nutrients.

It’s best when purchasing fertilizers to look for ones that are specific for rose bushes. This will ensure your roses get the nutrients they need to stay healthy – and more importantly – keep blooming.

There are now many fertilizers that are especially formulated for roses. They include the main and trace nutrients need most for better health and blooming.
How & When To Apply – How To Deadhead & Fertilize Rose Bushes

For purchased liquid or granular fertilizers, be sure to read the label instructions. It’s always best to go on the more conservative side when applying commercial fertilizers. That means applying it at about 2/3rds of the recommended rate.

If using compost tea or worm casting tea to fertilize, aim for using about one gallon of water per plant. Water plants at the roots as well as directly on the foliage for double the absorption power. See our article: How To Make Compost Tea

As for how often, you should be fertilizing every 2 to 3 weeks throughout the spring and summer months for potted roses. For tea roses, Grandiflora and miniatures roses, about every 3 to 4 weeks. And for shrub and climbing roses, once every two months.

With all fertilizers, be sure to apply them early in the morning and not during the heat of the day. This can often burn the plants from the sun, especially if it is liquid fertilizer.

Do not add any fertilizers about eight weeks prior to your first frost date for your location. Any young, new growth after this point will be susceptible to damage from colder temps and frost.  

It’s always best to water and fertilize roses in the morning.

A Few Extra Tips – How To Deadhead & Fertilize Rose Bushes

Be sure to water roses deeply during overly dry spells during the summer months. Avoid watering bushes overhead since having water in the blooms and on the foliage can cause them to be more susceptible to diseases.

Water deeply early in the morning. Apply enough so that the water can reach about a foot down around plants. Adding mulch can be a great way to help retain moisture and cut down on watering. It also helps keep competing weeds at bay.

When deadheading spent blooms, you can also lightly prune rose bushes during the summer months as well. Not only will this help to keep them tidy, but it will also keep the plant healthier too. 

Roses can become victims of powdery mildew, black spot, and rust. You can remove individual leaves, or prune entire stems. Clip the shoots and stems that are showing signs of damage or that have simply started to get a little unruly.
