For plants that will overwinter, such as roses, berry bushes, etc., in Central Sweden you should not fertilize after mid-July, roses maybe not after the beginning of July, because later fertilization causes the plants to delay their hibernation, which makes it easier for them to overwinter. How late it is suitable to fertilize depends on how sensitive the plant is and how far north you live, but for roses in Mälardalen it can e.g. be suitable to suspend sometime between the first and the 10th of July. Lawns can probably be fertilized until mid-August.
For crops and plants that will not overwinter, such as most vegetables and summer flowers, you can continue to fertilize in the right amount as long as they grow and the frost comes. Lalso sow tall annual crops where the edible part does not risk coming into contact with urine, such as corn and kale. Also low- and medium-tall annual crops that are harvested late and that should not be overwintered, such as Swiss chard, lettuce, white cabbage, etc. can be fertilized until harvest, provided that care is taken that no golden water splashes on the parts to be eaten. For vegetables, you should stop one month before the expected harvest, if you cannot avoid urine ending up on the vegetable parts that you are going to eat.
In general, you can say that the harder it is for the plant to overwinter and the further north you live, the earlier you should stop, as you don't want the wintering processes to be delayed by the plant being encouraged to continue growing due to the nitrogen in the Golden Lake. This applies regardless of whether the plant is evergreen or not.
The absolute best is to pour the urine into plastic sheets and save it for spring. The next best thing is to pour it into a large garden compost bin. If you have a separate drain, you can also pour the urine on the land where you will grow nitrogen-loving plants, such as spinach, chard, corn, beetroot, for the summer. However, spread over a decent surface, so that there is not too much in one place.
