Cultivars
Corabel
French variety. Heavy and reliable cropper but may require good conditions to crop well. Good pollinator.Very tasty nuts.
Cosford
Traditional variety. Very good pollinator for other species. Vigorous growth. Yield relatively low compared to other varieties but reliable performance in a wide variety of conditions.
Dutch EMOA 1
Recent Dutch cultivar performing well in trials in UK and the Netherlands. Good yields of large nuts.
Fertile de Coutard (syn. Barcelona)
Vigorous tree with female flowers appearing at a very young age. Has produced nuts on three year old trees at our site in Westport. Although grown mainly in France and Spain, appears adaptable to Irish conditions.
Gunslebert
German variety. Heavy and reliable cropper. Good flavour.
Hall's Giant
Hardy, vigorous and productive variety with large nuts. Good flavour. Best performer in trials by the Agroforestry Research Trust in Devon. Will begin producing nuts at a very young age.
Lange Tidling Zeller
German cultivar. Heavy yields of small to medium sized nuts. Long attractive catkins.
Longue de Espagne
Compact tree suitable to smaller gardens. Early ripening.

Cobnut Orchards
We are very interested in supporting the establishment of commerical-scale cobnut orchards in all regions of Ireland. To date, we are working on the setting up of two nut orchards - respectively containing 80 and 150 nut trees - in county Mayo. Once the trees reach ful bearing potential, we expect average annual yields of 3-4 kg per tree. At a planting density of 12-16m² per tree, this gives 625-830 trees per hectare planted (250-330 trees per acre) with an annual yield of 1900-3300 kg per hectare (750-1300 kg per acre). However, significantly higher yields may be possible. New planting techniques involve planting the cobnut trees much closer together, and yields of up to 6000 kg per hectare (2400 kg per acre) appear achievable. We will be reporting more on this in the near future.
As it can take up to 12 years for cobnut trees to reach the start of their production plateau, we strongly recommend planting well developed 3, 4 or even 5 year old container-grown trees, that have the potential to begin nutting from the word go. Our 150-180cm container-grown trees will reach 2 meters or more the first year after planted, with good side branch development. Providing sufficient different cultivars are planted to ensure pollination, there will be a modest crop of nuts the very first year, with a far bigger crop the year after. This is in marked comparison to very young cobnut trees, which need several years before even the first nut appears, and which require a lot of looking after in the first few years, and particularly dislike competition from weeds around the base of the tree.
We are gradually building up a stock of even larger container-grown trees, which will begin producing good nut crops even sooner after planting. We provide a full consultancy service, including detailed site assessment, site preparation and planting services, annual pruning, and after sales support.
We also offer reasonable discounts for large planting schemes. Please enquire for further details.
