    Urea is very high nitrogen, which will promote vegetative growth but not flowering. It's best to use a complete organic fertilizer that has a balance of all essential plant nutrients,with plenty of Phosphorus. In the US I'd use a product of 5-7-2 with the following ingredients:
    Nutrient-rich Cottonseed Meal, Wild-caught Alaskan Fish Bone Meal, Wild-caught Alaskan Fish Meal, Valley Grown Alfalfa Meal, Cold Water Kelp Meal, Naturally Mined Potassium Sulfate, Mined and Micro-nutrient dense Colloidal Soft Rock Phosphate, Micro-active Micro-nutrient-rich Seaweed Extract.
    Here in Thailand I make my own blend with bat guano, bone meal, sulfate of potash, magnesium sulfate and other ingredients for primary, secondary and trace mineral nutrients.
    I'm sorry I don't know what is available in Zambia. Check with a local garden center or online sources like Amazon.com or whichever source will deliver to your area.
    EM or compost tea is a good addition to your soil fertility program, but will not furnish complete nutrition by itself.
    Can you get hydrolysed fish fertilizer and kelp meal?

    When growing miniature roses indoors, it can be challenging to find a spot where they'll get several hours of direct sun each day.
    Water regularly, dead head the spent flowers, Roses go dormant in winter and will drop their leaves. Giving roses a rest period in winter will prolong the life and health of the plants. Keep them cool during this time.

    Thanks for this simple and straightforward article. My new house has tons of rose bushes, and I am not a gardener. Going out to give this a try.

    It is too late for heavy rose pruning this year. Annual pruning is done just as the leaf buds start to swell and before the canes leaf out. Still, you should prune out dead, diseased and damaged canes to the ground. If 2 canes are rubbing against each other, this damages the bark and allows disease to enter. Remove one of the 2 canes. Your rose is very crowded which blocks sunlight and greatly reduces air circulation. If you find branches that grow inward instead of outward, remove these. Late next winter, start removing the large canes to the ground. Whether you do this all at once or spread it over 3 years is a personal decision although roses typically respond to pruning with vigorous new growth. Regular fertilization helps the rose stay healthy and blooming. https://www.gardeningknowhow.com/ornamental/flowers/roses/pruning-roses.htm

    It has been several days since you posted your question. I think no one has responded because they just aren't certain of the answer. In researching canker, I found no mention of replanting in the same area. However, I'm hesitant to say it never lingers in the soil. Think of all the pathogens that do persist. I would err on the safe side and treat the soil with a fungicide rated for rose canker. Then I would use it as a preventive maintenance for the first few years as canker is preventable, not treatable as you discovered.

    Put the pots in full sun. As long as they are in soil and will be planted in a few weeks, full sun is best. Keep them outdoors. They will leaf out in sun or shade but not be able to generate photosynthesis in shade. Leafing out drains the roots from energy so rebuilding the roots before blooming begins is important. Roses in southern Michigan are beginning to leaf out. If you notice this in your neighborhood, that is another indicator that keeping them in sun is the best strategy. If the snowstorm in the west comes your way, tuck them into a garage or shed until the storm passes.
