I really like the Get Growing Bundle and have ordered and used several of these over the past 3 or 4 years. I especially like the Mint Compost - I use it as a top dressing around those roses that need a little "pick-me-up." I refer to the Mint Compost as "Rx for an ailing rose."
I am not as impressed with the Fish Fertilizer. Used at label strength it seemed to burn many of my 200+ plants last Spring. Even when applying at half the recommended rate there seemed to be an adverse reaction to it. I still have a lot of the fish remaining (as I ordered a case of it plus a gallon) and am hesitant to use it in the rose garden this year. I am left wondering if I just got a bad batch? It's unlikely I'll be ordering the fish in the future.
That aside I love Heirloom Roses. Since 2021 I have ordered about 40 roses from Heirloom. They are always true to variety and arrive very well packaged (industry best). They start growing immediately and sometimes growth is so strong right out of the gate that I am amazed. They are good people and I will continue to support them.
