Fertilizing Roses: Everything You Need to Know

Welcome flower gardeners! Whether you’ve been tending roses for years or you’re just starting off, knowing the right fertilizer to give your roses can make a big difference in their growth and bloom cycle.

To help you understand how to effectively fertilize your roses, we’ve compiled a comprehensive guide that will cover everything from the type of fertilizer to use, to how often it should be applied and other important tips. Read on and get ready to give your roses the optimal conditions they need!

What Is Fertilizer?

Fertilizer is a material added to soil that contains essential plant nutrients such as nitrogen, phosphorus, and potassium (N-P-K). It helps ensure that plants have access to the necessary nutrient elements for healthy growth and development throughout their life cycle, from seed germination all the way through flowering and fruiting.

By providing these essential nutrients in adequate quantities, fertilizers allow plants to maximize their potential growth and yields while also improving soil structure and fertility over time.

What Do Roses Need?

Roses require more phosphorus than other plants because they are heavy bloomers, this means they need more of this particular nutrient in order to produce the large number of flowers they are known for.

An ideal ratio for rose fertilizer would be something like 18-24-16 (N-P-K). If you are using a general complete fertilizer with an N-P-K ratio such as 5-10-5, 4-8-4, or 4-12-4, then make sure it has an adequate amount of phosphorus in order for it to be effective on your roses.

Special Rose Plant Foods

Rose plant foods are specifically tailored towards the high phosphorus needs of roses in order to help them produce plenty of beautiful blooms throughout their growing season.

They usually come in a powdered form that can be mixed into your soil or applied as a spray directly onto leaves and blooms, some brands even come with additional micronutrients such as magnesium or iron that are beneficial for roses as well!

General Complete Fertilizers

In addition to special rose plant foods, general complete fertilizers can also be used on roses as long as they have an adequate amount of phosphorus, look for an N-P-K ratio such as 5-10-5, 4-8-4, or 4–12–4 if you want something that’s suitable for roses specifically.

These fertilizers not only provide essential macro nutrients like nitrogen, phosphorus and potassium but also include micronutrients like iron and magnesium which can help with overall plant health and vigor too!

Key Nutrients For Roses

In addition to nitrogen (N), phosphorus (P), and potassium (K), there are several other key nutrients that are important for healthy growth and maximum bloom production in roses: calcium (Ca), sulfur (S), magnesium (Mg), iron (Fe) and boron (B).

All these elements should be present in an adequate amount when choosing a fertilizer for your roses, some brands may even include additional micronutrients such as zinc (Zn) or manganese (Mn). It’s always best to check the label before purchasing any fertilizers so you know exactly what’s included!

Organic Fertilizers For Roses

Organic fertilizers are becoming increasingly popular among gardeners as they are natural products made from organic materials such as composted manure or seaweed extract, these types of fertilizers not only provide essential macro nutrients but also help improve soil structure over time which is beneficial for long term health of your plants!

Organic fertilizers tend to release their nutrients slowly over time so it’s important not to over apply them — always check the label instructions carefully before using any organic fertilizer on your roses!

Slow Release Fertilizers

Slow release fertilizers contain both macro and micronutrients which release their nutrients slowly over time providing long term benefits without needing frequent applications, these types of fertilizers are great for busy gardeners who don’t want the hassle of applying fertilizer every few weeks!

However make sure that the slow release fertilizer you choose has an appropriate N–P–K ratio suitable for roses — usually something around 18–24–16 would do just fine!

Different Types Of Fertilizer

When it comes to rose care there are many different types of fertilizer available — ranging from liquid concentrates which can be mixed with water before application, granular formulas which can be spread directly onto soil surfaces or incorporated into planting beds, slow release granules which slowly release their nutrients over time thus eliminating frequent applications, organic products made from natural materials like composted manure etc., all the way up to specialized rose plant foods specifically tailored towards heavy bloomers like those mentioned earlier in this article!

Ways To Apply Fertilizer To Roses

When applying fertilizer there are several different methods depending on what type you’re using: liquid concentrates should be mixed with water before being applied directly onto leaves/blooms with a watering can/sprayer, granular formulas should either be spread directly onto soil surfaces or incorporated into planting beds, slow release granules should simply be sprinkled evenly around each rose bush at appropriate intervals – usually once per month during active growing seasons is sufficient, organic products should either be mixed into soil prior planting or incorporated into mulch/compost around existing plants – again at appropriate intervals throughout the growing season!


Now that you know all about how best to feed your precious roses – let’s get out there and start making them thrive! With just a little bit care when selecting the right type of fertilizer – along with proper application techniques – you can ensure that your blooming beauties get all the essential nutrients they need while also boosting soil structure over time – resulting in healthier plants overall!
