Fertilizer for potted rose babies

21 years ago

I'm hoping Kaye will see this and give me a tip on how to keep the baby roses growing strong and healthy. These were winter cuttings that I did in pots of professional potting soil mixed with about 1/3 coconut coir. They are just not taking off as fast as in the past when I stuck them directly into the garden....even though I had to dig and pot them in May.

I have been afraid to use the stronger chemical ferts on them, so used fish emulsion and alfalfa tea. I am pretty sure they are needing micronutrients...iron in particular. Can they take something like Miracle Grow..if so, what strength? I want that good dark green color like I see at nurseries, but don't want to burn tender new roots. These guys have been uncovered for 5 weeks and in full sun for 2.

    I'm no expert but would use half strength Miracle grow or compost or manure tea.There aren't any nutrients in potting soil.Posy Pet

    My sis with the greenhouse uses the pelleted fertilizer in all pots of growing things. I also noticed it in the potted roses I got from Ashdown this spring. It won't burn anything and is good for several months depending on the brand you are using. I am using it when I pot up perennials from 6-paks to larger grow-on pots. I also then water with very weak liquid solution.

    Thanks guys! I am getting the same answer from the rose forum on this. I think I may have used some Osmocote, but the temps may be the problem...that stuff needs soil temp of 70 degrees to work. Also, I may be expecting too much from them too soon. I noticed that I have red new growth on about 5 of them, so I think they are about ready to take off. I will give them a shot of half strength Miracle Grow and see if it will kick start them. They had rooted about 2 months ago, but may have been working at building a bigger root system before heading for the sky. Some of the old garden rose cuttings are taking off at a faster pace... they just don't seem to be nearly as fussy.

    Mille, I just saw this..I use the Pennington slow release Nursery and Landscape fertilizer (14-7-7) on the babies when they have grown out some. Until then, we use MG 1/2 stength and fish emulsion or seaweed. I can usually tell by looking when they need something stronger than tha "baby formula" but you are right about the soil temps causing the delay in the time release. I'd hit them again a couple of times with the liquids. Ron adds super phosphate and compost when he moves them up, too.

    Thanks Kaye! Guess I am always in a hurry, but I want them to grow off fast so they can be ready for winter. I want some early basal breaks.

    I have some good looking activity on the cuttings you gave me. You were right about Lamarne...sure hope it has some roots to go with all the new growth. The Chinas are being slow, though. I only see one leaf that looks like it may be going, so far.

    What is the right name for the "Mexican Hydrangia"? I wanted to look it up, but no luck without the correct name. Had to pamper them a bit...carrying them home bare root, wrapped in wet newspaper set them back quite a bit, but they are getting to where they can tolerate more sun without wilting, now.

    Millie, I got lots of hits for Mexican Hydrangea, try clerodendrun bungei and see what you get. I just did a Google .

    Huummm! I must have misspelled Hydrangea or something. I got plenty of hits, too. LOL Well, now I know what I am working with. Thanks!
