It is always important to remember that post-harvest care of shrubs is essential.
In this case, the raspberries will not "offend" you next year either.
This procedure can wait until the end of the month, but it is absolutely necessary to do it. In this case, the harvest next year can be much richer than this season.
The raspberry has given up all its reserves during fruiting, so it is time to replenish them.
The classic option for this time of year is compost with manure. It will be necessary to add ten kilograms for each square meter of raspberry.
Superphosphate will not be superfluous either. You will need 50 grams for the same area. Potassium sulfate can also be added. Forty grams will be enough.
Before the cold weather, it is customary to use three buckets of water every 72 hours for each bush. This amount of liquid will be quite sufficient.
Remember that the water must be preheated to avoid increasing the risk of disease.
