Verovatno ste uocili kolika je cena caja od brusnica (100 gr oko 350 din).
Imali neko iskustva sa uzgojem i nabavkom?
Inace brusnica ili crvena borovnica ima latinski ili engleski naziv: Vaccinium vitis idaea - Vaccinium macrocarpa.
Eng - Cranberry.
Sudeci po informacijama sa Interneta ne bi bila preoblem za uzgoj i kod nas, (ako se nadje dovoljno kupaca za caj)
Pozdrav svima

Savo,
Brusnica raste na severu Evrope, ima je ovde u Finskoj gde ja zivim.. Njeno staniste je pod vodom, mocvarno a podloga je mahovina i bere se u kasnu jesen, i onda je voda ledena i branje nije bas zabavno! Sama biljka ima duge grancice koje na vrhu nose po jednu bobicu, no svaka grancica i ne nosi bobice.. pa je razumljiva cena caja
Inace kod ima je u Sloveniji ali nisam sigurna koliko i gde ?
Ja sam brala borovnice na Kopaoniku ali nikada nisam videla brusnice, pa i neznam da li je ima kod nas u Srbiji ?

Brzo sam promenio misljenje i vec sam nabavio jednu biljku koja je u veoma losem stanju (najveci deo lisca je opao). Posto imam dosta iskustva sa Rododendronima pokusacu da je revitalizujem. Pazzljivo sam proucio sta ima na internetu, ali me buni podatak da joj treba ocedita zemlja, CITAT: "well-drained soil is required for the development of healthy, functional cranberry root systems. However, evolution in a wetland setting has resulted in the ability of the cranberry plant to withstand periodic flooding without harm."
iako svi naglasavaju da raste na mocvarnom trerenu. Da li mozda znas u kom periodu svoje vegetacije ona mora biti stvarno poplavljena, a kada i koliko je samo u vlaznoj zemlji. Vidim da je zimi u Massachusettsu, radi zastite od hladnih vetrova kompletno potapaju (u led?). Izazov nije mali, svaka pomoc je dobrodosla.

Brusnica
(Lat. Vaccinium macrocarpa, engl. cranberry)
Brusnice spadaju u bobičasto voće koje, kao i borovnice, potječu iz Sjeverne Amerike. To je tvrda i crvena bobica koja zahvaljujući većoj količini vitamina C u svom sastavu ima kiselkasti okus.
Brusnicu su koristili u davnim vremenima starosjedioci Amerike kao lijek za mnoga stanja, između ostaloga i za upalu mokraćnih puteva. Tradicionalno, uz puricu i druga jela, Amerikanci tim bobicama proslavljaju Dan zahvalnosti i Božić.
U posljednjem desetljeću, veoma je popularan sok od brusnica. Osim toga, ovaj se dragocjeni plod može koristiti u svježem obliku, može se čuvati smrzavanjem ili sušenjem, a njime možemo pripremati i različite umake i ukusna jela.
Brusnice su, nutricionistički gledano, posebni plodovi bogati različitim zaštitnim tvarima, uz klasične vitamine i minerale i druge hranjive sastojke (vitamin A, vitamin C, kalij i biljna vlakna). U njima su okriveni brojni bioflavonoidi (npr. quercetin) koji imaju snažno antioksidativno djelovanje, čime smanjuju rizik oboljevanja od različitih karcinoma (posebno se spominju rak dojke i rak debelog crijeva). U laboratorijskim eksperimentima na životinjama, brusnice su svojim bioflavonoidima ne samo spriječavale rast stanica raka, već i njihovo metastaziranje. Antioksidansi osim toga pomažu i pri prevenciji određenih faktora koji potiču nastanak kardiovaskularne bolesti.
Hipurična kiselina, koja se također nalazi u brusnicama, predstavlja prirodni antibiotik, tako da se brusnicama pridodaju ne samo antibakterijska, već i antifungalna (protiv gljivica) svojstva. Antocianini i proantocianidi iz brusnica, osim antikancerogenog djelovanja, pomažu i pri obnovi stanica koje su odgovorne za vid. Brusnice uz sve to, djeluju i na snižavanje glukoze u krvi, što je jako korisno za dijabetičare.
Najvažnija stanja kod kojih se preporuča svakodnevna upotreba tih izuzetnih plodova jest u svakom slučaju upala mokraćnih puteva, budući da flavonoidi iz brusnica imaju posebno antibakterijsko djelovanje upravo u tom djelu tijela, zahvaljujući posebnim receptorima kojima se one tu vežu.
Istraživanja su pokazala da sastojci iz brusnica uništavaju i Helicobacter pylori, koji je u najvećem postotku uzročnik čira na želucu.
Osim toga, brusnice uništavaju i bakterije koje su naseljene u ustima i koje inače vremenom dovode do raznih bolesti zubiju i zubnog mesa.

Meni je brusnica toliko puta pomogla!
Imala sam prilike da pijem caj i da uzimam kapsule. Caj je odlicnog ukusa i podseca na borovnicu! Mmmmm... njam, njam!
Postoji kod nas da se kupi i neki koncentrat...
E sada, ono sto se da pirmetiti je to da je ona jaaako skupa ovde, tako da sam prestala i da je uzimam!
Zasto je to tako?!?!I da li se moze nekako uzgajati kod nas?!
Koliko znam, trebalo bi da je ima na nekim nasim planinama, valjda na Tari?!
Ako neko zna gde moze da se kupi ovaj caj, ali za pristojnu cenu, neka mi javi!

Pozdrav svima
Brusnica je vrsta bobičastog voća podrijetlom iz Sjeverne Amerike, tj. plod zimzelenog grma. Prvi uzgoj ove biljke započeo je već 1816. godine, na područjima gdje je brusnica rasla samoniklo. Tijekom lipnja i srpnja ta područja prekrivena su ružičastim cvjetovima i tamno crvenim plodovima brusnice. Ljekovita svojstva i način uzgoja čine brusnicu doista jedinstvenom biljkom.
Raste na pješčanim, suhim i tresetnim terenima gorskih (većinom crnogoričnih) šuma. To je niski, trajno zeleni grm sa čvorastim, okruglim stabljikama, te kožnatim, jajolikim, tamnozelenim i sjajnim listovima, na naličju točkastim, i malo zavinutim prema dolje. Cvijet je bijel ili ružičast, postavljen na vršcima stabljike u punašnim, visećim grozdićima. Plod čine koraljno crvene i kiselkaste bobice, nalik borovnici, koje zahvaljujući većoj količini vitamina C u svom sastavu imaju kiselkasti okus.
Brusnicu su u davnim vremenima koristili starosjedioci Amerike kao lijek za mnoge bolesti, između ostaloga i za upalu mokraćnih putova. Tradicionalno, uz puricu i druga jela, Amerikanci tim bobicama proslavljaju Dan zahvalnosti i Božić.
Ovaj se dragocjeni plod može koristiti u svježem obliku, čuvati smrzavanjem ili sušenjem, a u posljednjem desetljeću popularan je i sok od brusnica. Kao i od borovnice, i od brusnice se može praviti ljekovito vino. Osim toga, od brusnica možemo pripremati i različite umake i ukusna jela.

How Cranberries Grow: "Cranberries 101" - An Introduction
Background
Cranberries are a unique fruit. They can grow and survive only under a very special combination of factors. These factors include acid peat soil, an adequate fresh water supply, and a growing season that extends from April to November. Cranberries grow on low-lying vines in beds layered with sand, peat, gravel and clay. These beds are commonly known as bogs or marshes and were originally created by glacial deposits. Commercial bogs use a system of wetlands, uplands, ditches, flumes, ponds and other water bodies that provide a natural habitat for a variety of plant and animal life.
Classification
The North American cranberry, Vaccinium macrocarpon, is the fruit recognized by the U.S. Department of Agriculture (USDA) as the standard for fresh cranberries and the cranberry juice cocktail. The European variety, which is grown in parts of central Europe, Finland and Germany, is known as Vaccinium oxycoccus. This variety is a smaller fruit with anthocyanin pigment profiles similar to that of the North American variety. The European variety, however, has a different acid profile in terms of the percentages of quinic, malic and citric acid levels present. In Europe, this fruit is commonly known as lingonberry or English mossbery.
Cultivation
The cranberry is a Native American wetland fruit which grows on trailing vines like a strawberry. The vines thrive on the special combination of soils and water properties found in wetlands. Wetlands are nature's sponges; they store and purify water and help to maintain the water table. Cranberries grow in beds layered with sand, peat and gravel. These beds are commonly known as bogs or marshes and were originally formed as a result of glacial deposits.
In Massachusetts we call the place where cranberries grow a BOG. Natural bogs evolved from deposits left by the glaciers more than 10,000 years ago. These deposits were left in impermeable kettle holes lined with clay. The clay prevents materials from leaching into the groundwater. Rocks and other organic materials were collected by the glaciers. When the ice finally melted deposits of heavy materials were layered on top of the clay.
These kettle holes were filled with water and organic matter which created the ideal environment for cranberries. In the early 1800s Henry Hall, a veteran of the Revolutionary War who lived in Dennis Massachusetts noticed that sand blown in from nearby dunes helped vines grow faster. Today, growers spread a inch or two of sand on their bogs every three years. The sand not only helps the vines grow but also slows the growth of weeds and insects. Normally, growers do not replant each year since an undamaged cranberry vine will survive indefinitely. Some vines on Cape Cod are more than 150 years old and are still bearing fruit.
Location
Cranberries are grown through the northern part of the United States. The major production areas are New Jersey, Massachusetts, Oregon, Washington, Wisconsin and the Candian provinces of British Columbia and Quebec. Other regions include Delaware, Maine, Michigan, Minnesota, Rhode Island, as well as Nova Scotia and Ontario. These regions offer the special conditions that cranberries require, including sandy soil; abundant fresh water and a dormancy period that provides enough chill hours to produce a crop the following growing season.

Water Use in Cranberries
How Cranberries Grow: "Cranberries 101" - Winter
The Massachusetts Growing Season...
Winter flood
Cranberry bogs are flooded from late December through mid- March depending on the weather, to protect the vines and buds from winter injury.
Sanding
A layer of sand is applied to the cranberry bog every few years. This cultural practice is done to stimulate growth, improve drainage and control weeds, insects and fungi. Sand can be applied in several ways. With
sanding, sand is applied directly to the vines by a bog vehicle or by hand. In ice sanding, the sand is applied on the ice that forms on the winter flood. The third method is barge sanding, where sand is applied by using a barge on a flooded bog.Equipment maintenance and Construction
Since there are fewer than 1,000 cranberry growers in North America, large companies do not manufacture farm equipment for cranberry production. Most growers use the winter months to design, build and maintain their own equipment.
Brush cutting and Tree clearing
Growers often will remove brush and trees around the perimeter of the bog to promote air movement which helps reduce frost risk and cuts down on fungal growth. Removing brush and trees that serve as alternative hosts for weeds diseases and insects also helps cut down on pesticide use.
Grower Education
Through continuing education workshops, growers spend many hours learning the latest environmental and production related practices that will increase the efficiency and environmental compatibility of their operations.
How Cranberries Grow: "Cranberries 101" - Spring
The Massachusetts Growing Season...
Removal of Winter Flood
As warmer weather arrives, usually mid-March, growers remove the winter flood. The vines slowly come out of dormancy and the growing season begins.
Late water (Spring flooding)
You may see a bog re-flooded between mid-April and mid-May as a cultural practice to manage insects, weeds and disease.
Frost Protection
Water is applied through the sprinkler system to protect the cranberry bud in the spring and the fruit in the fall. This can occur anytime the temperature drops below damaging levels, usually between late evening and early morning hours.
Weed Management
As in your home garden, weeds in cranberry bogs must be controlled. This is done by an application of herbicides applied by mechanical means, holding late water (spring flooding) or hand pulling.
Fertilizing
Typically, fertilizers are applied between mid-May and late August. As native wetland plants, cranberry vines require minimal nutrient supplements. When needed, fertilizers are applied in small doses by helicopter, manually, or through the sprinkler system.
Construction and Renovation of Cranberry Bogs
Many of the bogs in Southeastern Massachusetts have been in production for more than 100 years. Sometimes a bog may be replanted because: the bog may not be level, the variety is a low producer or weeds such as briar, poison ivy, or brambles have overtaken the vines. In such cases, large construction equipment is needed to move the soil, leveling the bog in preparation for planting new vines. Growers also may square off beds to increase operation efficiency. From time to time it is also necessary to upgrade or replace irrigation systems and water control structures.
How Cranberries Grow: "Cranberries 101" - Summer
The Massachusetts Growing Season...
Irrigation
The old rule-of-thumb is that cranberries require up to one inch of water per week during the growing season. If rainfall is inadequate, water is applied through the sprinkler system.
Weeds
Weeds may appear on a cranberry bog during the summer. Workers hand pull weeds or wipe them with a manual or mechanical herbicide applicator.
Bees
Pollination is an essential part of cranberry growing. Growers utilize one or two bee hives per acre of bog during bloom, early June through mid-July, to pollinate the cranberry flowers.
Integrated Pest Management (IPM)
Most growers use IPM techniques as an ecological approach to pest control. IPM includes a combination of biological, cultural, or chemical control methods. Throughout the spring and summer, IPM scouts use insect nets and sticky traps to monitor pest activity.
Pesticide Application
Insecticides and fungicides may be applied during the summer months to control or prevent serious damage caused by various insects and diseases. Pesticides are only used when necessary and are applied by state certified applicators. Although occasional applications may be made by helicopter, the vast majority are made through the sprinkler system.

The Massachusetts Growing Season...
Harvest
The cranberry harvest takes place once a year from mid-September through early November. There are two methods of harvesting cranberries.
Harvesting harvesting involves using walk-behind machines to rake the berries off the vines into boxes or bags. Berries are removed from the bogs by either bog vehicles or helicopters. The fruit is delivered to fresh fruit receiving stations where it is graded and screened based on color and ability to bounce (soft berries will not bounce). harvested cranberries are used to supply the fresh fruit market. These cranberries are most often used for cooking and baking. Wet Harvesting
Cranberries have pockets of air inside the fruit. Because of this, cranberries float in water, and thus, the bogs can be flooded to aid in removal of fruit from the vines. Water reels, nicknamed “egg-beaters” are used to stir up the water in the bogs. By this action, cranberries are dislodged from the vines and float to the surface of the water. Wooden or plastic “booms” are used to round up the berries, which are then lifted by conveyor or pumped into a truck to take them to the receiving station for cleaning. More than 85% of the crop is wet harvested. Wet harvested cranberries are used for juices, sauces, or as ingredients in other processed foods.
Ditch cleaning
Ditches are necessary for the flooding and drainage of a bog. The network of ditches must be kept free flowing. Ditch cleaning is usually done in the spring and fall by hand or a mini-excavator. The mud piles are removed by either a bog vehicle or helicopter.
How Cranberries Grow: "Cranberries 101" - Water Use
The Massachusetts Growing Season...
The old rule-of-thumb states that cranberry vines need approximately an inch of water a week to grow. Growers use water to protect cranberries from frost and hot weather in summer. As a general rule, each acre of cranberries will use seven to ten feet of water to meet all production, harvesting and flooding needs. There are two main ways cranberry growers bring water onto the bogs – through sprinkler systems and through flooding.
Sprinkler Systems
Sprinkler irrigation supplements soil moisture, protects the buds from spring frosts and the berries from fall frosts and cools the plants during intense summer heat. There are two vital operations performed by sprinklers on cranberry bogs - Irrigation and Frost Protection.
Irrigation
Cranberries can require 0.20-0.25 inches of water per acre per day during the hottest, driest and windiest weather. The standard recommendation is for vines to receive an inch of water per week from either rain, capillary action from groundwater, irrigation or some combination of these. Best Management Practices recommend irrigating in the early morning, so as not to extend the time the plants are naturally wet. This practice also minimizes loss from evaporation, run-off and drift, which can amount to 30 percent of water that comes out of the nozzle.
Frost Protection
Frost protection applies water to prevent damage to buds and berries when they are sensitive to temperatures below freezing. There are two times of the year when cranberry growers worry about frost – in the spring and in the fall. It is necessary to apply at least 0.10 inch of water per acre per hour to provide basic frost protection. This will protect the plants to about 24 degrees F under calm conditions.
Flooding
The other practice when cranberry growers use water on the bog is flooding. Flooding is so important in cranberry cultivation that bogs where flooding is not possible are no longer considered profitable. Cranberry growers use flooding as a management tool to protect the plants from the cold, drying winds of winter, to harvest and remove fallen leaves and to control pests.
Winter Flood
Cranberry vines may be injured or killed by severe winter weather. This injury, winterkill, is prevented by protecting the vines with a winter flood. The winter flood may be applied as early as December 1 and remains on the bog as long as winterkill conditions are present or forecasted. Generally, growers hold the flood no later than March 15.
Late Water
Another flooding technique cranberry growers use is known as late water. Late water floods have been used since the 1940’s and have been used to protect the bog from spring frost and to provide some pest control. In modern cranberry production, holding late water refers to the practice of withdrawing the winter flood in March then re-flooding the bog in later April for one month.
Harvest Flood
The most widely-known use of flooding in cranberry cultivation is for harvest. Approximately 90 percent of the crop is harvested this way. Flood harvesting occurs after the berries are well colored and the flood waters have lost their summer heat. The bogs are flooded with up to one foot of water. In order to conserve water, harvest is managed so water is reused to harvest as many sections of bog as possible before the water is released from the system. Flood water is recycled in the cranberry bog system, passed from bog to bog through canals and flume holding ponds and reused, often shared by several growers.
