Raspberry - tasty and incredibly useful berry. These qualities culture is so appreciated and loved that practically in each garden or kitchen garden it is possible to see this plant. However It should be noted that the taste of raspberry and the sizes of berries can change from year to year, here a lot of things depend on leaving and weather patterns.
Perhaps, everyone likes to regale on sweet and fragrant raspberry in the summer. However it is possible to make it not always for the reason that berries urozhdatsya absolutely tasteless moreover and small. The events reasons a little and not to be disappointed in harvest, it is necessary to create for culture the most favorable for it conditions.
So, in most cases raspberry grows sour and small from the shortage of nutrients. On branches and leaves of culture often happens it is visible what elements are not enough for it, for example, leaves from lack of potassium and phosphorus turn yellow and dry, escapes from lack of nitrogen, etc. to Malines best of all atrophy to feed up three times a year - right after snow thawing, during blossoming and after harvesting or in the fall. As fertilizer it is better to use complex industrial medicines or self-made on the basis of manure or humus.
Crush and become sour berries of raspberry can from lack of light. From this it is possible to draw conclusion that if the raspberry brake was thickened (long ago it was not thinned out), or row has built any construction protecting culture from direct sunshine, then you should not wait for some sweet berries. Only removal of excess escapes and transfer of design will solve situation.
Ambient temperature also contributes to maturing and filling raspberry. In cool weather all processes in plants because of what the taste of berries, their size and quantity suffers slow down. As it is impossible to affect weather patterns, exit only one - at least for the night to cover raspberry brake with ukryvny material.
Insufficient and excessive watering also negatively affects harvest (and not only raspberries). The fact is that scarcity of water in the soil makes impossible absorption of nutrients from soil (plants just starve), and here its excessive surplus dilutes nutrients to such an extent that culture, absorbing water, receives few minerals and also ""starves"". Conclusion: watering has to be moderate. In the period of rains it is necessary to dig out furrows on perimeter of raspberry brake and to build drainage systems.
