If your plants are producing little fruit, it is worth giving potassium sulfate to support flowering and production while protecting the plant from the cold. Thefertilizationsof theraspberrythere are two, one in spring and one in autumn. When the raspberry is grown in pots, the fertilizations will be carried out with liquid fertilizer to be administered once a month from March to October / November.
In spring, apply mature organic fertilizer to the foot of the plant while in autumn, prefer a potassium-based fertilizer.
Potassium sulphate is very useful for strengthening the tissues and increasing the resistance of plants to late frosts, excellent for preventing any damage to the flowers and above all for increasing fruit production.
Where to buy potassium sulfate? In garden centers, at agricultural consortia or by taking advantage of online sales. On Amazon, a 1.25 kg pack of potassium sulfate is offered at a price of 19.28 euros with free shipping. It is useful for all plants that fear the cold.

Some raspberry varieties such as Rossana, Heritage and Tulameen show a high sensitivity to these fungal diseases.
In this context, the treatment to be performed serves to prevent and contain the spread ofillnessesfungal already occurring on raspberry plants. The most effective products are those based on water-suspended solutions of Trichoderma harzianum Redo strain KRL-AG2 or strain T-22 to be used diluted in water or through localized irrigation with dripline.
For the dosages, I refer you to the instructions found on the product packaging but usually a dose of 10 grams is recommended for each plant in case of infection already in progress, or only 1 gram per 15 meters of row if the treatment is only used for prevent disease.
