If your results are negative, there were no signs of a gonorrhea infection. If your results are positive, the Neisseria gonorrhoeae bacteria was found in your urine. It is possible to test too early after being exposed to the infection.
The best time to transplant a rose is in early spring when the rose is still dormant. This causes less stress and shock to the plant. Timing is everything. Wait until all threat of frost or freezing weather has passed.
Container roses can be planted at any time during the year, but I advise planting Knockout roses in containers in the spring. This gives the shrub a chance to get well established through the warm months before it goes dormant in winter.
