CULTIVATION OF CURRANT BERRIES (2023)

A gooseberry is a sour to sweet edible fruit from a gooseberry bush (Ribes uva-crispa). Currant bushes are native to Europe and North America, but are cultivated all over the world and have been cultivated by humans for over a hundred years. There are several named gooseberry cultivars, so it is important to choose one that is suitable for your area and preferences.

Size

Gooseberry bushes can be kept at 3-5' tall and 3-5' wide. If allowed to grow taller, its branches will not be strong enough to support them and will become limp and spread out.


pollination

Gooseberries are self-fertile, so they don't need another variety as a pollinator to produce fruit.

maturation time

Depending on the variety and location, the fruit ripens from summer to early autumn.

Gooseberry is hardy in USDA zones 3-8 unless otherwise noted. This rating provides the minimum winter temperature that plants will typically survive if properly hardened. On our website you will find aUSDA resistance mapswhich provides information about the average minimum winter temperature in your locality by postal code.

CULTIVATION OF CURRANT BERRIES (1)

Many plants native to places with cold winters need a cool hour to ensure an even spring awakening of flower buds and leaves. The chill hours requirement of plants varies by species, cultivar, and sometimes by the dormancy achieved.

Currants need to be planted where they will receive at least 8 hours of direct sunlight measured in early summer (late June to early August) for best fruiting and where they will receive afternoon shade in hot summer locations. Sufficient sun exposure triggers the start of new flower buds for the next growing season, without which there will be no fruit. Fruit ripening and flavor development are also favored by the production of carbohydrates stimulated by the sun and its heat.

Gooseberry tolerates a wide range of soils as long as they are well-draining, moderately rich, and have a pH of around 6.3 to 6.8. Amend the soil where you plan to plant by mixing an inch or two of plant-based organic matter (fertilizers work best for vegetable gardens), peat moss or coir in an area 1 1/2 to 2 times the size of the diameter of the required planting hole and up to a foot deep. A 2- to 4-inch layer of mulch (straw, leaves, or wood shavings) applied after planting further improves the soil.

When choosing a planting location, plan for enough space for both the crown and the roots. Please refer to the size descriptions for each variety and remember these are generally managed or trimmed sizes, not the maximum possible sizes. When planting an orchard, be sure to leave enough space between rows to move supplies and fruit.

To grow a gooseberry in a pot, you'll need a finished container size of at least 10 gallons. The bushes will grow taller in a larger container, but make sure you have the skills and tools to move the weight of the pots. In order for the root system to become established, it is important to gradually increase the size of the container over several years, rather than going straight from small to very large.

Do not use soil from your garden in the pot, but a mixture of potting soil with some compost. For larger pots, use a potting soil that contains larger particles as well as smaller ones.

water your tree

This is the most important and often the most difficult part of successfully growing plants. There are many factors including humidity, temperature, soil type, wind and the amount of direct sunlight that affect how much and how often water should be applied.

A general rule of thumb for buried plants is to make sure they receive an inch of water a week above the root zone. An inch of water is about ¾ to a gallon per square foot of soil surface. The typical three-foot diameter planting hole would require 7½ to 10 gallons of water per week, provided by rain or by the gardener.

Apply this water once a week, twice a week if the soil drains quickly. This obviously depends on your own conditions and the plants you are growing!DO NOT watereasy every daybecause this results in a wet surface and a dry root area. The soil should be moist for most growing plants, but not soggy to a depth of about a foot. The top inch or two may look dry and the plant is still well watered. The trick is to have the water available where the roots are. In warmer, sunnier areas, a mulch of straw, bark, etc. can greatly reduce the irrigation load in summer.For plants in bathtubs,Water until the soil is saturated and water runs out of the drainage holes. Allow the container to dry out until the soil is 1 to 2 inches dry (deeper for deeper pots) and the container is lighter.A withered plant canget too much or too little water.

In rainy areas like the Pacific Northwest, most of the plants we offer require relatively little additional watering once they are well established in the soil and have had a chance to develop a good root system. But again, it's important to make sure the plants are watered regularly and deeply during the first few growing seasons, and the first summer is particularly critical.In drier areas or where the soil does not retain water well, constant irrigation is essential.Remember that your trees weren't just made to survive, they were made to thrive. Make sure they get their water where they need it, starting at the drip line and extending away from the tree to several feet (on older trees) where the forage roots will be. Drip irrigation and drip lines can be an efficient way to distribute water.

fertilization

For good, even growth and high productivity, your trees must have adequate levels of various mineral nutrients. Some people are lucky and have naturally rich and fertile soil.

Use an all-purpose or balanced fertilizer. A few inches of well-rotted compost on top of the root zone can also be an effective fertilizer. A generous mulch of leaves or straw around your trees not only conserves moisture and helps control weeds, it also keeps the soil healthy by building humus, attracting earthworms and supporting beneficial fungal organisms. This encourages young trees to be strong, healthy and productive. Avoid applying fertilizer after the onset of summer, as this can encourage a lot of tender new growth that is much more likely to be damaged by the winter cold. Overuse of fertilizers can increase and even kill disease problems in your plants.

As a general guide, if your tree is producing about a foot or so of new growth per year and has healthy looking foliage, it may not need a lot of fertilizer, if any.


Find out which insects and diseases are typical of your region. Ask your local cooperative advisor what typical insect and disease problems are in your area. You can then make a selection based on the resistance or tolerance information available in our catalog, or create a plan to control any issues you might expect with the susceptible strains you plan to grow. If you see resistance information for a specific disease for one cultivar but not for another of the same fruit cultivar, that cultivar may be susceptible or untested and therefore unknown. Below are some of the most common issues.

anthracnose leaf spot

symptoms

Leaves develop brown spots, turn yellow, then fall off.

Kontrollmethoden

Copper fungicide applied in autumn, winter or spring. Prune weak or damaged wood.

Comments

Rake leaves under the plants in autumn.

Blasenrost White Pine

symptoms

Extensive red-tinged blisters on black currant leaves. Defoliation often occurs with bad infections.

Kontrollmethoden

Spray copper fungicide before rain in autumn. Repeat in early spring.

Comments

Black and flowering currants tend to be more susceptible than red and white currants. Do not plant closer than 900 feet of white or 5-needle pines.

imported gooseberry worm

symptoms

Leaves eaten, starting at the bottom of the bush and working their way up and out. Tiny green caterpillars line the chewed edges of the leaves. It can look leafless almost overnight.

Kontrollmethoden

Spray with pyrethrin or rotenone when spotting the small green caterpillars and subsequent generations during the summer. Manually search and destroy daily. Cover with floating line cover.

Comments

Ducks easily find new caterpillars. Use Bioneem or Spinosad.

blackcurrant fly

symptoms

Infested fruit full of tunnel grubs ripen and drop prematurely.

Kontrollmethoden

Spray with rotenone when the flowers fall. Or use Spinosad or Bioneem. Collect and discard the affected fruits. Protect the bush with a floating cover during fruiting, but tie it down to prevent pests from climbing underneath. Shallow cultivation under bushes to expose egg and larval cases to predators can reduce populations.

Comments

Plastic mulches during fruit ripening can help prevent larvae from entering the soil.

Reh

symptoms

Truncated branches surveyed. Of course, the leaves are eaten or the plants are uprooted.

Kontrollmethoden

Fences or cages at least eight feet high. Plastic mesh, electric fence or braided wire.

Comments

In Raintree, an eight-foot deer wire fence worked best. Repellents do not work consistently. and only trained large dogs patrolling the perimeter are effective. Some have had success with the "Deerchaser" product.

Vogel

symptoms

Fruits disappear or have holes. Strawberries, blueberries, cherries and hazelnuts are the most susceptible, but most fruits occasionally suffer.

Kontrollmethoden

Reflective anti-bird tape can work well. bird net. cages.

Comments

Blue jays start picking hazelnuts when they are ready to be picked, and so should you. Nuts dropped by jays are usually empty.

Rat/Mouse/Rabbit

symptoms

The bark is eaten in a range up to 8 inches above ground level and the roots are also eaten, usually in snowy areas with lots of mulch or tall grass at the base of trees.

Kontrollmethoden

Keep the mulch 4"-6" away from the trunk. Keep the grass short and 1 to 2 feet from the trunk. Use a vinyl tree shelter wrapped around the trunk until the tree is well established.

Comments

Voles and mice chew a few inches above the ground and also on the root system. Rabbits will chew up to 8 inches tall, especially apple trees.

mites

symptoms

Dotted leaves, very small crawling insects on underside of leaves. Webs are often also present on the underside of leaves or around new shoot tips.

Kontrollmethoden

May develop resistance to pyrethrin/rotenone spray. release predatory mites. Insecticidal soap with ultralight oil. It is usually not a problem if pesticides are kept to a minimum.

Comments

Dust mites thrive in hot, dry weather.

aphid

symptoms

Pear-shaped insects 1/32 to 1/8 inch long that reproduce quickly, especially on the underside of leaves and on stems. It can be pink, green, black or white. The leaves turn red or curl and the stems turn black with soot.

Kontrollmethoden

Natural enemies such as ladybugs and parasitic wasps often provide control. Remove aphids with water spray. Spray with pyrethrin, rotenone, insecticidal soap or retarded sleep oil. Check for ants if they are also present.

Comments

Trees can tolerate some infestation. Observe in late spring and summer. Control is more important with new trees. Grow plants that attract predators, e.g. B. dill or yarrow.

ant

symptoms

Numerous ants run up and down the tree trunk; Large numbers of aphids, mealybugs or mealybugs, a lot of sticky honeydew, perhaps soot.

Kontrollmethoden

Find mounds and apply pesticides. Apply the Tangle Trap using a 2- to 3-inch-wide paper tape wrapped around the trunk. Delete other paths in the tree.

Comments

Ants feed and protect these insects in exchange for their sugary secretions. Insects can be difficult to control until ants are controlled.

brown marbled bedbug

symptoms

Spot-like feeding damage with subsequent rotting of fruits, nuts, berries and leaves. Deformation of healthy tissue around dead tissue. Brown spots can appear on stored fruit.

Kontrollmethoden

Monitor with traps, some broad spectrum pesticides may work. Researchers are working to find effective controls, but no information has yet been released.

Comments

BMSB hibernates in groups in dry shelters such as houses. If you find them in your house or in your house, use the vacuum cleaner, squeezing will release its repellent smell. Visit stopbmsb.org for more information. Feeding begins in the spring when the weather warms up and continues until the new adults go dormant for the winter.
