This is the first time I am going to try them on my seedlings. I found a video that you can mix it with any organic fertilizer (including liquid) and yes it is not supposed to burn the plants. So I have roses 🥀 that struggle when it is summertime so i want to dump a few spoonfuls on top (since I have no time to repot) and then also use AgroThrive. They are beautiful roses that have been neglected because of my obsession with desert roses .
