The subject of pollination is often made unnecessarily complicated. All fruit trees will crop satisfactorily in an urban situation as insect pollination activity covers considerable distances. However, if your garden or orchard is in an isolated area then the following information could be helpful when selecting varieties:
|Self-Fertile||Flowering Group||Good Pollinator|
Follow the tips above for guidance for apples and pears. Apples in particular are regular croppers and Malus crab apples are excellent pollinators for apples and are mostly SF themselves – see below. Pears prefer to have a warm sheltered position to set a good crop.
Triploid varieties are poor pollinators for other varieties, they are identified by this symbol in our catalogue and on our labels:
They should be accompanied by two compatible varieties that pollinate each other, or one self-fertile variety that flowers at the same time as the triploid.
Most varieties are self fertile. The few which aren't are unlikely to need a pollinator unless planted somewhere very remote.
Most good garden varieties are self-fertile. Due to pollen incompatibilities pollination of non self-fertile varieties is not obvious so for clarity we have listed some combinations below. All self-fertile varieties are known as 'Universal Donors' in that they will pollinate any other cherry trees that flower at the same time, so if unsure then just include at least one self-fertile variety in your garden. Sour cherries, such as Morello and Meteor Korai, are all self-fertile, they can pollinate sweet cherries but sweet cherries will not pollinate them.
|Bradbourne Black||Pollinated by Sunburst|
|Colney||Pollinated by Stella or Sunburst|
|Early Rivers||Pollinated by Merton Glory, Stella or Noir de Guben|
|Kordia||Pollinated by an SF variety, Penny or Regina|
|Merchant||Pollinated by Lapins, Merton Glory and Noir de Guben|
|Merton Glory||Pollinated by Stella or Sunburst|
|Noir de Guben||Pollinated by Colney, Merton Glory or Early Rivers|
|Penny||Pollinated by any Self Fertile variety|
|Regina||Pollinated by any SF variety, Penny or Kordia|
|Sylvia||Pollinated by Celeste or Regina|
|Van||Pollinated by Lapins or Vega|
|Vega||Pollinated by Lapins or Stella|
All varieties are self fertile.
Crab apples blossom profusely and often for longer periods than other apples so they make excellent pollinators. Of particular use are Golden Hornet, Evereste, Golden Gem, Red Sentinel and Butterball. They are all self-fertile.
Self-fertile varieties include Vranja, Aromatnaya, Meech's Prolific and Serbian Gold. Other varieties may need to be accompanied with a pollinator.
Broadview and Buccaneer are the two self-fertile varieties we would recommend for gardens. Other varieties are likely to be partially self-fertile and would benefit from nearby pollinators. Walnuts are pollinated by wind rather than insects so bear this in mind when choosing your site.
Hazels will crop better if varieties are mixed together but due to the abundance of hazels in the wild good crops usually appear. Like walnuts, pollination is mostly carried in the wind.
This problem is not uncommon in more traditional or heritage varieties. An overset in the ‘on’ year exhausts the trees resources and it does not have the energy to set fruit bud for next year’s crop, don’t forget that next year’s blossom is forming in the previous July and August just when the current crop is ripening –its all too much for the tree! So the remedy is as follows:
