Does there need to be two walnut trees to produce walnuts?

No, walnut trees are monoecious, meaning individual trees have both male and female flowers, allowing them to self-pollinate and produce walnuts without the need for another tree. However, having multiple trees can increase cross-pollination and potentially improve fruit yield.


How close does another plum tree need to be to pollinate?

A maximum distance would be 50 feet. However, as close as possible is much better as fruit set drops off with increasing distance. Studies have shown that even when two plums are planted next to each other, the side facing the pollinator will have more fruit. Bees are the main pollinator, and wind does not have much part in the pollination of plums. Make sure you have two varieties that will be compatible, as not all plums will pollinate each other - and that includes two of the same variety.


How much pollen is required to pollinate a plant?

The amount of pollen needed to pollinate a plant varies depending on the plant species. Some plants require only a few grains of pollen, while others may need more. In general, most plants need multiple pollen grains to ensure successful pollination.


Do you have to plant 2 plum trees for pollination?

Plums are not self-fertile. They need pollen from another tree or shrub.Plums belong to the genus "prunus" and it has been argued that any other prunus tree or shrub should be able to successfully pollinate a plum blossom. However, there are a few considerations:1) Getting the pollen from "father" to "mother". Bees, hover flies, moths, and other insects are the best way. Sometimes over short distances wind can do it. However the pollen has to get from point A to point B. You can try doing it yourself with a feather duster.2) Timing of flowering. Unless the "father" and "mother" plants are blooming at the same time, they can't get together. This is critical. Warmer locations result in earlier blooming, so a plum tree on the sunny side of a house may bloom earlier than one on the shady side. Different varieties also bloom at different times.3) Variety of plant. The best advice is that Asian plums will pollinate other Asian plums. Hybrid plums are best pollinated by wild plums. Hybrid plums will not pollinate other hybrid plums. See the University of Saskatchewan's article by Dr. Bob Bors and Rick Sawatsky.If you are talking about a very warm climate like California, there may be varieties of plum with different considerations."Jack Horner"........Added::: There are many varieties of European derived plums that are self pollinating. Green Gage is an excellent quality old European variety that can have green yellow skin. Asian derived plums (often called Japanese plums) need cross pollination with another Asian variety except for a few certain varieties like Santa Rosa It's a Japanese plum and it's self pollinating..European and Asian plums will not cross pollinate....Check with your local plant nurseries there are several varieties of self-polinating plum trees available depending on your area/climate ect...


Do trees need carbon dioxide?

Trees do contain carbon. Trees take in carbon and convert it to carbon dioxide which is then released into the air as oxygen.

How does an apple flower pollinate?

It depends on the type of apple tree, some are self pollinating and some need other trees pollen in order to pollinate.


Do you need two apple trees to polinate?

Not necessarily. If you have other plants in your garden (Flowers, shrubs, etc.) you will not need two apple trees. If you have no other plants in your garden, then yes, you will need two apple trees to pollinate.

How many trees can a bee pollinated?

A single bee visiting flowers for nectar and pollen can potentially pollinate several hundred flowers a day, depending on the species of bee and the availability of flowers. This can contribute to the pollination of multiple trees in the area.


Why do Apple farmers purchase bees?

Apple farmers need bees to pollinate their apple trees. Where bees have been eradicated by pesticides, more bees, or hand pollination, are necessary for the trees to bear fruit.


Do you need 2 Stella cherry trees to bear fruit?

It depends on the variety. Many varieties of fruit tree are self-sterile, meaning that they cannot pollinate with themselves. Due to grafting, if you buy two trees of the same variety, they are genetically identical- basically they are the same tree. So, you need a different variety of the same fruit in order for cross pollination to occur. Some trees are more genetically compatible for cross pollination, which is why in nursery catalogs, different trees are said to be good pollinators. Commercial orchards often plant crab-apple trees in with the apples to ensure good pollination.


Why doesn't greenhouses need insects to pollinate flowers?

In short, they do. Greenhouses are not usually sealed, and insects can get in and out, and they will pollinate the flowers.


Why do flower need bees?

Bees pollinate the flowers.


What kind of tree will cross pollinate your luscious pear tree?

Summercrisp, Patten, Parker, Ure and Golden spice are good choices with Summercrisp, Ure and Golden spice being good choices for the northern regions. Keep in mind that Luscious is pollen sterile so you may need 3 trees to get a fruit set on all.


Who need bees?

Us! Bees pollinate plants and give us food like fruit and vegetables. Flowers also need bees to pollinate them so they can produce seeds and bloom.
