What is the best fertilizer to use on roses please ?

Hello! First of all, you need to check your plant hardiness zone. I am providing a link to the plant hardiness zone map so that you can see which zoned you live in. The zone tells you which plants to be planted at which time depending if you’re north-south Easter west. You’re unsuccessfulness with roses may have to do with the time you plant them in the soil you’re using.

Next, and providing a link to a guide and planted roses. With both of these links you should be able to successfully grow your roses. Good luck!

Here's an article from Heirloom Roses with everything you need to know: https://www.heirloomroses.com/info/care/how-to/fertilize/

There are fertilizers specific to roses...

Use Bayer a systemic Rose care....fertilizer,insect control, and fungus control

Next to the rose bush roots, bury egg shells and banana peels!

This is going to sound odd...but...i mix granite dust with my soil, the other plants love it, but roses thrive. The truth!!!!!

My roses LOVE banana peel..bury it by the roses :-)

You’re welcome! Wishing you a successful outcome!

Unfortunately those are 2 things I’m allergic to....
