..standard advice is to give half feed to new bare roots. i.e. one small handful... two small handfuls for 2nd year and above roses... repeat process June/July time... I tend to stick to that... an important point to note is that to feed new bare root roses only when you see active growth... nice new shoots, which can be as late as mid April for some..
..this applies to shrub roses which don't like to be hurried along.. hybrid teas and floribundas, which are usually quicker off the mark and flower more in the first year, I treat the same as established roses... some caution is needed for potted roses, I tend to do half feed for those as I'm supplementing with liquid feed later on...
@Marlorena, thanks for that info on feeding. I need some advice please. I've unexpectedly got a spare space in one of my front borders for one of newish bare roots I potted up last autumn. Would it better to plant it in the ground now (where a small shrub had been) or just stand the pot plus rose in the spot and plant it in the dormant period? Most of my pots are biggish terracotta ones, although one of the 5 roses (which are all doing well with lovely new growth) is in a tall metal pot.
@Lizzie27 ...this is a nice easy question for me to answer... leave it in the pot for this season, on the site you intend to plant it, and empty it out in the autumn and plant it then... you've gone to the trouble of potting it up, and you will feed and water through the summer.. it will develop a nice big root system in that time, and be better for it... here's an example of one I did late October last year, having grown it in a pot all summer.. ...look at the nice large rootball... this rose established well during the winter and will be one of my first roses to bloom this spring.
My experience is that roses planted in a hole with amendments (compost, manure) have enough nutrients for at least first half of the season. It may make sense to feed a bit after the first flush, I do heavily diluted tomato food or seaweed extract. If it is slow-release or organics, it won't do much harm if used sooner. But I don't want to force leafy growth before the roots are developed enough.
May I ask a you question @Marlorena about using Mycorrhizal fungi and rose fertiliser when planting out bare root roses that are currently potted up, but will be going in the ground in late April/early May? I have a couple of spots where roses were previously planted so want to use the MF there. How long afterwards is it appropriate to apply the fertiliser? I understand (from somewhere, can’t remember where) that one cancels out the other, is that true?
Mountainous Northern Catalunya, Spain. Hot summers, cold winters.
@Nollie ...use the MF in the planting hole on the root system as instructed..... apply fertilizer to the surface area only, not in the hole... it's the phosphorus in the fertilizer that destroys the MF if used together in the bottom of the hole... which is why MF and Bone Meal should not be used together...
