Osmocote Plus.

Thanks Shelia! What do you use for baby plants? Heirloom said I needed to fertilize, but with a liquid, so I was using Neptune's harvest. The plants seem to do fine, but wanted to see if there is a different approach.

I give my new roses a little Alaska Fish Fertilizer liquid. Boy does that stuff stink! I I often mix it in a watering can (with a spout), and pour it lightly over the foliage in the evening or a cool day. It’s easier than getting the sprayer out. I then pour the leftovers into the soil the roses are in. only do this for a few months and when they are growing well, I switch to something like Oscomite Plus. I’ve used others, but Oscomite Plus has become my go to. It’s time released, so I just note in my calendar when I need to apply it again. It lasts for months, so it’s easy to forget when they are due for another round. I’m not sure if this is the “recommended way”, but everything has done just fine. I wish you much success! Lisa
