On this page I will deal with rose fertilizer choices for gardeners, so you can best decide what type of fertilizers to apply to your roses.
Fertilizers come in two general classes: manufactured and natural.
Manufactured fertilizers are made in a chemical plant. Common examples are Scott, Miracle-Gro, Peters and Vigoro.
There are lots of store brands also. Often manufactured fertilizers are also called chemical or conventional fertilizers.
As a group, they are applied in relatively small amounts and have relatively high levels of nutrients, such as nitrogen, phosphorus and potassium.
Some also have minor trace elements like sulfur or iron, and even trace elements like copper or zink.
Natural, organic fertilizers, are made from the remains of previously living creatures, or their waste.
Things such as blood meal, bone meal, cotton seed meal, worm castings, fish emulsion and animal manures are natural fertilizers.
Some companies blend various naturals together to make a more complete fertilizer than say, blood meal, which is primarily nitrogen.
Here are my favorite blended, natural fertilizers for roses: Dr. Earth, Happy Frog, Epsama, Alaska and Whitney Farm.
Natural fertilizers tend to be much lower in nutrients than manufactured ones.
So it can take a lot of fertilizer to get the same general effect, such as a high flower production, which is what we rose gardeners all strive for.
Personally, I use both manufactured and natural organic fertilizers.
Every spring, after the annual major pruning, I amend my soil in the rose beds with a bag of Dr. Earth's rose fertilizer and composted manure.
I love horse manure and so does my roses, so whenever I can get it I use it with abundance.
After that I use Miracle-Gro for roses fertilizer every 2-3 weeks during the growing season, which is very long where I garden in Los Angeles.
In areas that are prone to rose fungal diseases, I recommend using the Bayer All in One Rose and Flower Care.
It's a marvelous systemic product that feeds your plants and at the same time protects against disease and pests.
There is no spraying involved. You simply mix it in a bucket of water and pour it around your rose bushes 3 -4 times during the season.
It's by far the best systemic rose product out there, which I can personally attest to.
Follow these step by step instructions and the fertiling schedule for growing rose bushes for maximum flower production.
We all want our roses to bloom all season long, and if you have repeat-flowering varieties, you need to apply nutrients all season long.
