I wish I had a nickel for every time someone came to my yard, admired my plants and then said since I was a "professional" I must be using some secret fertilizer on my plants to make them look so nice. Are they surprised when I explained I buy what is cheapest at the time! K-grow from K-mart for a liquid fertilizer. High in Urea so it takes about two weeks before you see any reaction by the plant. I mention this because their are no "miracle fertilizers". I am not buying tomato grow, rose grow ect for each plant i fertilize. Yes I agree some plants are more heavy nitrogen feeders than others. Sometimes the issue is the fertility of the soil you have. I have used 10-10-10 on my tree fruits with good results. I have used lawn fertilizer (28-0-16) and had good results too, just use at a much lower rate as higher in nitrogen. My soils are fine on phosphorus and we have a phosphorus ban here anyway unless it is a new planting. I did not spring for a soil test but let the trees tell me the problem. I strive for 18"-24" of new growth on young fruit trees. If I don't get it, then next year I fertilize. Too much growth, then cut back or eliminate fertilizing the following year. I fertilize all my young fruit trees with a granular fertilizer just after leaf out by broadcasting it around the drip-line of the tree. My soil must be very low in nitrogen as imust apply a lite application around old established trees too or their foliage turns yellow-green by mid-June. I fertilize the old trees at about half the rate I use on the young ones so I do not promote a lot of growth but have good leaf color. I know this is not scientific but it has worked for me and I am happy with the results. If I was professionally growing fruit for a living, I would gladly pay for a soil test as well worth the cost and not worth the risk of going without it.

OK if you haven't applied any fast nitrogen for a few weeks. I doubt that nitrogen affects bloom cycles. It may lengthen stems slightly. The new Rose Tone has 2% fast nitrogen, so 8 oz. of it would be similar to 1-1/2 oz. of 10-10-10 -- that's ignoring the 3% slow nitrogen in RT, which would not be a concern. I would separate them by 4-6 weeks, because you don't want to double up on fast nitrogen.

Using just Easy Feed won't have any detrimental effect on your roses. Think of you drinking a can of Red Bull once a week for your energy boost. It'll last for an hour or so but then another can would be necessary to maintain the energy. Easy Feed is similar. It shows in the plant's growth. A quick spurt of green and larger leaves is followed by smaller leaves until another dose is applied. Feeding a slower release product results in a steady even growth pattern. A little fertilizer applied often is better than a lot all at once. Organics or slow release chemicals such as Osmocoat release nitrogen at a slow steady rate, while the high nitrogen liquids give a quick shot then are gone.

Yes, the fertilizer recommendation is almost certainly a wild shot in the dark. As bb has already said, get someone there who knows something, or take sample to plant pathology lab if there is one in your area. Do you see any resinous globs of material below any branches that are unhealthy or dead? +oM
