Raspberry Glen Ampl: secrets of the variety's popularity and its features
Raspberry Glen Ampl is a European guest who is currently successfully winning her place in Russian gardens. This new promising variety quickly became widespread in Western Europe and occupies a leading position in the total planting area in industrial plantations and in garden plots. Such wide popularity of raspberries Glen Ampl is promoted by its high productivity and endurance in combination with high taste.
The history of growing raspberries Glen Ampl
Raspberries Glen Ample (Glen Ample) was created in 1998 at the Scottish Institute of Plant Industry in the city of Dundee (Dundee) by crossing the British variety Glen Prosen and South American raspberries Meeker. The selection result was successful: the absence of spikes and endurance were transmitted to the Glen Ampl variety from the first parent, and the high growth force and yield were transmitted from the second parent.
The raspberry variety Glen Ampl was not included in the register of selection achievements of the Russian Federation, however, it was widely used in all regions due to its excellent characteristics. It is grown both in farms and in summer cottages.
Description and characteristics of the variety
The maturity of Glen Ampl is medium-late; the first berries in central Russia can be tasted in the second or third decade of July. The fruits ripen gradually, the yield of the crop lasts for a month. The ripening period may vary depending on climatic and weather conditions. The main crop is formed on two-year-old shoots. Glen Ampl - ordinary raspberries (not remontant), but sometimes in a very warm climate with a long summer season in August, flowers and ovary can form on the tops of annual shoots.
One of the features of Glen Amplus is strong-growing, stiff, rather thick stems up to 3–3.5 meters high, which give the plant a resemblance to a small tree. Bark on ripe grayish-brown shoots with a slight waxy coating. The length of the laterals reaches 0.5 m. Spikes are completely absent on the shoots and laterals.
Laterals are fruit twigs with leaves and inflorescences that form on two-year-old shoots.

The productivity of raspberries Glen Ampl is high and stable. Two-year-old shoots bear fruit, from 20 to 30 fruit branches are formed on them, on each of which up to 20 berries are tied. From one fruitful shoot you can get a crop of 1.2 to 1.6 kg. When grown on an industrial scale, the yield is 2.0–2.2 kg / m2, but in garden areas with increased attention to each bush, gardeners received a yield of up to 4–6 kg per square meter. Such a high yield characterizes the Glen Ampl raspberry as an intensive type variety with great potential for fruitfulness, and this is its main advantage.
The productivity of the raspberry variety Glen Ampl is high - up to 1.6 kg from one fruitful shoot
Berries have a round-conical shape, when ripe they acquire a dull red color. The average weight of the fruit is 4–5 g, but with good care it can reach 10 g. Ripened berries are easily removed when harvesting. The presentation of the product is very attractive. Due to the delicate sweet and sour taste of juicy berries, tasters rated the Glen Ampl variety at 9 points. The direction of use of fruits is universal, berries can also be frozen.
Berries of raspberry Glen Ampl round-conical shape, their weight is 4–5 g (can reach 10 g)
When ripening, the berries can be on the bushes for 2-3 days without losing commercial qualities, so you can not pick them every day. The dense structure of the berries and firmly bonded drupes contribute to the preservation of the fruit during harvesting and transportation.
Glen Ampl berries are highly portable
Raspberry Glen Amplus is hardy to adverse factors. Winter hardiness and drought tolerance are estimated at 9 points, in frosts below -30 ° C the shoots require shelter. Immunity to diseases - 8 points, resistance to pests - 7-8 points. Plants are not damaged by aphids, but may be susceptible to viruses.

Features of planting and growing
Raspberry Glen Ampl has good economic characteristics that allow you to get a decent harvest in any climate. However, taking into account the peculiarities of agricultural technology of this variety, it will be possible to increase its productivity.
The place to grow Glen Ampl, like any other raspberry, it is better to choose open and sunny, but if this is not possible, then the variety can tolerate a slight shade. The soil structure should not be too light or too heavy. The variety is quite hardy to dry air and soil, but still grows better, bears fruit and tolerates winter on moderately moist soils. On marshy places it does not grow, since it does not tolerate the wetting of the root system.
Glen Ampl, unlike many other European varieties, quite successfully tolerates Russian frosty winters. Best of all, bushes of this variety winter in regions where there is snow cover throughout the winter, in which case the plants do not need additional shelter. In the southern latitudes, where there is not enough snow and often there are winter thaws, there are critical reviews about this variety. Not always successfully plants tolerated such winter conditions. We can conclude that the most comfortable raspberry Glen Ampl will feel in the middle latitudes, where there are quite warm summers and snowy winters.

Raspberry Glen Ampl is demanding on the nutrient content in the soil, with a lack of potassium and phosphorus, productivity decreases, as well as the size and quality of berries. It is important when preparing the soil before planting to make a sufficient amount of organic matter. For digging over 1 m2, 2-3 buckets of humus or compost are brought in. 1 liter of wood ash and complex mineral fertilizers are added to the planting pits.
Since the bushes of this variety are very vigorous, a thickened planting will contribute to shading and create the conditions for the development of fungal diseases. In industrial cultivation, the distance between rows should be 3–3.5 m, and between seedlings in a row - 0.5–0.7 m. In the conditions of a garden section of an aisle, you can reduce it to 2.5 m or make a one-line planting. The remaining requirements for planting this raspberry variety are standard for this crop.
The aisles for strong-growing raspberries Glen Apple should be wide, 3–3.5 meters
Caring for raspberries Glen Ampl
This variety is prone to intensive shoot formation and needs to be standardized in quantity. Experienced raspberry growers from the fall recommend leaving up to 20 shoots per linear meter. In the spring, they again inspect the bushes and leave 10-12 replacement pagons per linear meter. When placed in a row of plants at a distance of 0.5 meters, it turns out that 5-6 shoots remain per bush. The tops are shortened by no more than 20–25 cm, since fruitful twigs are formed along the entire length of the shoot. Long pruning increases the volume of the crop and the duration of its return.
Two-year-old shoots during ripening of the crop do not withstand its severity and require garter. The height of the trellis should be 1.8–2 m. The so-called spiral method has proven itself when gartering with very mature varieties of raspberries. Only the first shoot is tied to the trellis. The next one is led outside the row, wrapped around a wire in a spiral and bent under the first. Thus, all subsequent shoots are fixed. The advantage of this method is that you do not need to tie up each shoot, all branches and laterals have enough space, good access is formed for harvesting. Fruit branches, despite a considerable length, are quite durable and do not require a garter.

Despite the fact that the Glen Ampl variety is positioned as relatively resistant to dry air and soil, the yield will be higher and the quality of the berries is better if the plants are provided with sufficient watering. Especially raspberries need moisture during the setting and filling of berries. To maximize the preservation of moisture in the soil, mulching with organic substances is used, as for any other raspberry.
Intensive type varieties, such as Glen Ampl, reveal their full fruiting potential only if the soil is adequately supplied with nutrients. Raspberries are especially sensitive to a lack of nitrogen, as they carry it out of the soil in large quantities.Recent entries In April, I process roses so that no pests encroach on my beauties

Feeding with liquid organic fertilizers is most effective, such as: fermented infusion of bird droppings (diluted with water in a ratio of 1:20) or cow manure (diluted 1:10). 3-5 liters of such fertilizer are applied per square meter. In the absence of organic fertilizers, a urea solution (30 g per 10 liters of water) of 1-1.5 liters per bush is applied. The first feeding is carried out in the spring, and then fed another 1-2 times with an interval of 2-3 weeks.
Diseases and Pests
With a fairly high immunity of raspberries Glen Ampl to diseases (8 points) to avoid infection, as a rule, it is enough to comply with the growing conditions and the rules of agricultural technology, as well as preventive measures. Thanks to the wax coating on the stems, the plants are relatively resistant to fungal diseases such as didimella and anthracnose. There is some vulnerability of the variety to viral diseases, as well as with high humidity and thickened plantings, raspberry Glen Ampl can suffer from powdery mildew and rust.
With raspberry disease, powdery mildew on the berries, growth points of young shoots and leaves, patches with a light gray bloom of a weblike nature are formed (look like sprinkled with flour). Fruits lose their presentation and quality, become unsuitable for consumption. To combat powdery mildew, biofungicides (Fitosporin-M, Planriz, Gamair and others) are used, which are environmentally friendly. These preparations contain live bacterial cultures that inhibit the reproduction of pathogenic fungi. Chemicals such as Topaz, Bayleton, Quadris and others are more effective (but also less harmless).

Signs of raspberry rust are small convex yellow-orange pads on the upper side of the leaves, as well as gray sores with a rim of reddish color on annual shoots that merge into longitudinal cracks. Severe rust damage leads to drying out of the leaves, which affects the yield and reduces the winter hardiness of plants. The most effective way to combat this disease is to use chemical fungicides, such as Poliram DF, Cuproxate, Bordeaux fluid and others.

The following measures are recommended for the prevention of raspberry diseases:
- the use of healthy planting material;
- thinning plantings;
- timely harvest;
- cleaning the site of plant debris affected by diseases;
- spraying with fungicides in early spring before buds open, during the appearance of buds and after harvesting.
Raspberry Glen Ampl is resistant to aphids, which is a carrier of many diseases. In order to prevent the attack of other pests, a number of preventive measures are used:
- digging the soil under the bushes;
- timely cutting and burning of old shoots, rejuvenation of raspberry;
- regular inspection of plants;
- collection of damaged buds of raspberry-strawberry weevil.

Reviews on Raspberry Glen Ampl
And I liked the Glen Ampl variety. The berry is beautiful, the taste is average, but not so bad, the yield is also good. And also with us, he is only now giving away the berry when everyone has already disposed of it, that is, it turns out to be more late than average, as stated. A very early and late berry (summer) is appreciated.Nab
This spring I bought this variety. It came up very tightly, but the shoots proved to be very powerful and strong (although I doubted that something good would happen with a spring planting) - not a very strong root and the likelihood of drying the roots was also possible. But - what can I say by grade? Without thorns is a plus! The taste is normal (good), although it is difficult to judge by the first berries. The berry is large! He left the signal bush, so this branch was so covered with color that he doubted whether it was worth leaving so many ovaries.Vladidmdr-76
Glen Ample is starting to ripen, what can I say? I am surprised and amazed. Berries hang from the marigold, and then only once, and turn into a ball, the size of a hryvnia. And the taste is really very good. Better Lyashka or not, this is the business of everyone who tries these two varieties. Why is it good for me (taste), then Lyashka's berry is somehow dry, and Glen is juicier!Limoner
Last fall, planted 50 bushes. As previously stated, the seedlings did not sit very long in the ground, although the root was developed, previously soaked in the root. He planted in a trench method. The distance between the rows is 2.0 m (now I realized that it’s not enough, there are two rows of 25 bushes each). The distance in the row is 0.5 m. This spring 38 bushes barely got out (well, at least that). The height of seedlings is different, from 30 cm to 1.5 m. There were 3 signal bushes, the berries left, but normalized, 3–7 pcs per bush. When I finished it, tore it off, tried it. I didn’t really like it, although it was red ... The next berry sagged longer, plucked a burgundy. The taste is pleasant. Sweet with sourness. Fleshy. For an amateur. For me it’s on a 4 on a 5-point scale. The berry has a pleasant raspberry smell. Large size. Dense. As for the fact that it is filmed badly ... I did not notice. Failed when I finished, well, all. Regarding that, it crumbled ... Even burgundy berries on the table lay for 2-3 days and did not lose density. Were eaten after this experiment) In the course of the taste has not changed ... If it is removed poorly and the berry is crumbled, are you sure that this is Glen Ampl? She shouldn’t behave like that ... On a garter .... I’ll probably still tie it up. Only the stems that bear fruit are tied up. Young animals do not tie, it’s easier to harvest, bent and climbed into the thick) By trimming .... I cut all raspberries in the autumn after cleaning to the height of the trellises. If you do not cut, how to collect from a height of 2.5-3.0 meters? It’s inconvenient to take off a stepladder.entiGO
Glen Apple finally ripened the first berries. The taste is harmonious, I like it, the size is impressive, does not crumble, ripened berries are easily removed.Irina (Shrew)
Hello! I used to grow raspberries for about 15 years, which variety I don’t know, but this year I got a full crop with Glen Ample. I am delighted the harvest is just super and I like the taste, the berry is large and sweet. In 2013, together with Glen Ample, I planted Patricia, the Beauty of Russia and Lilac Fog, so I liked the Glen Ample variety the most.Victor Molnar
This variety is better than others brought to buyers (it leaks less and chokes) about the yield and size (weight) of berries I am silent, it is a pleasure to collect (high performance), the taste is not the best, but buyers take it more expensive for the size of the berries and the best look. Thanks and glory to the English breeders-breeders.bozhka dima
