Any such thing as male and female tree?
I was told by my local nursery folk when I tried to purchase an asian pear
tree. He said that I should plant at least two's that way they can cross-pollinate one another, and hopefully one is male and the other is female ! I was aware of cross-pollination business, but I really got lost when he mentioned about male/female plant!! I would like you experts in this forum to comment on the subject --- he seemed to know what he was taking about. If he was right -which I doubt it, how do I correctly pick the right sex? Thanks in advance JIMMY |

Thanks in advance JIMMY I have a single asian pear that bears. I also have a male holly planted on purpose. Single and double flowers yet another variable.

Don't know if it's sex but some varieties of Asian Pears need another
variety close by to have good production. Same as some apples. You can find out which varieties grow well together. Having 2 trees of the same variety won't do much for you. Ginko! Now there's a tree where sex counts. It takes 20 years before trees bear fruit. Many cities planted them without knowing the sex and decades later ended up with a stinking mess. These days nurseries graft from known male trees so there won't be any stinky fruits. Smells like dog shit. |

Thanks in advance JIMMY You have single sex trees that are either male or female aka "monoecious" And you have trees that produce both pollen and have ovaries aka "dioecious" But some trees that are dioecious are also self infertile and cannot pollinate themselves.

Thanks in advance JIMMY This subject is much more complex than it first appears. Yes there are species of plants that have separate male and female plants, clearly in this case you need at least one of each, an example is the kiwifruit. Pears are not in this category. The reason that you may be told to get more than one of certain fruit and nut trees is that although they are both male and female often their self fertility is low or non-existent. In some cases to get the best result you just need more than one plant of the same cultivar in other cases different cultivars are better. The latter situation is common. In the case of pears some are self-fertile but many will produce a much reduced yield unless paired with the right cultivar. You didn't say what type you have so I cannot look it up. David |

Thanks in advance JIMMY You have single sex trees that are either male or female aka "monoecious" And you have trees that produce both pollen and have ovaries aka "dioecious" You have monoecious and dioecious reversed. For more detail than the OP probably wants see http://www.malvaceae.info/Biology/SexDistribution.html But some trees that are dioecious are also self infertile and cannot pollinate themselves. The usual situation in Rosaceae is that plants are synoecious (all flowers produce pollen and have ovaries) but there are exceptions. I would expect that pears are the same, and the need from a separate pollinator arises from self-incompatibility rather from the trees being gendered. However to be sure one has to investigate, as you say below, the situation obtaining in a particular species, or even a particular cultivar.

Thanks in advance JIMMY Besides Ginkgo and some hollies (Ilex), ash trees (Fraxinus) and Asparagus have the sexes separated. I strongly recommend planting only male ash trees. 32 years ago, I didn't realize how important that is. Now, the most common weed in my garden is the seedlings of the ash tree I planted long ago. For eating, some prefer female Asparagus officinalis. The ornamental A. densiflorus 'Sprengeri' has attractive berries (as does A. officinalis). However, those berries quickly become new plants, possibly another weed. -- David E.

Considering many trees these days are grafts. Buying 2 trees of the
same variety amounts to buying the same tree with 2 individual rootstocks. |
