Yellowing

[Toddz]

I have been struggling with these rugosa roses for 3 years now. They start out growing great and then they yellow and struggle the rest of the year. I have tried several individual nutrients and combinations and I can't bring them out of it.

Is it time to move them? I have rugosa roses and other roses growing everywhere in our flower beds and they do great with very minimal care.

That looks like a micro-nutrient deficiency not a NPK deficiency. Try a product called Chelated Iron.

Thank you. I have tried it before and it helped but maybe I need to use it on a regular basis instead of just once.

If the other plants are healthy and this one in this specific place has this yellowing on a regular basis it has to be something connected to the soil. Have you tried KEEPING composted manure around the base of the plant out to the drip line. I suspect something such as a large rock is keeping the roots from growing deeply in that spot or something is leaching nutrients away such as a lawn sprinkler. In any case I would use the chelated iron on a monthly basis for a year and see if this doesn't make the situation improve.

Sometimes the pH gets too high and the plant cant uptake the iron in the soil. Check the soils pH.

I have plenty of composted manure so I will put some around it.

We think the area may have been a rubbish pile 20 or 30 years ago based on the pottery and glass shards that we find there. I will give it 1 year of chelated iron and composted manure and if it doesn't improve, then I will move it.

The shallow rooted carnations growing around them are doing great. So I suspect it could be rocky further down because we have pulled out large rocks and bricks in the area.

I'm going to send a sample through our extension office next week.
