How do you know if a flower is pollinated?
There are a few ways to tell if your plant has been pollinated. One is by observing how many bees or similar pollinators such as butterflies or hummingbirds visit the plant. If you notice a great many bees in your garden, the flowers are almost certainly pollinated.

Pollination occurs when birds, bees, bats, butterflies, moths, beetles, other animals, water, or the wind carries pollen from flower to flower or it is moved within flowers.
Wind and insect pollination
Wind-pollinated plants let their pollen blow in the wind and hope that their pollen grains reach another plant for pollination. Insect-pollinated plants use insects and other animals to carry their pollen grains to other plants.
Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species. Self-pollination occurs in flowers where the stamen and carpel mature at the same time, and are positioned so that the pollen can land on the flower's stigma.
Pollen from a flower's anthers (the male part of the plant) rubs or drops onto a pollinator. The pollinator then take this pollen to another flower, where the pollen sticks to the stigma (the female part). The fertilized flower later yields fruit and seeds.
For Honey bees and wasps, they are most active during the afternoon from 1 pm to 4 pm (PDT). For butterflies and dragonflies, they are more active midday 11 am to 2 pm (PDT). And for hummingbirds, they are most active during the late afternoon 3 pm to 4 pm (PDT) or early morning 8 am to 10 am (PDT).
Types of self-pollinating flowers
Plants that self-pollinate include several types of orchids, and sunflowers. Dandelions are also capable of self-pollination as well as cross-pollination.
If the process has been carried out properly, in just a few days you will see the seeds begin to grow inside the calyx of the female flowers. Once the plants have been pollinated, most of the seeds will take 4-6 weeks to fully mature (always depending on the strain).
In the pollination process, the male pollen will land on the female part of the flower, the pistil of which the stigma is a part. Pollination is necessary for reproduction and seed formation, but it is not the same as fertilization.
How can I help my plants pollinate?

- Create drifts. ...
- Add water. ...
- Provide shelter. ...
- Try trees. ...
- Include natives. ...
- Let herbs bloom. ...
- Use pesticides wisely.
Pollination is not just fascinating natural history. It is an essential ecological function. Without pollinators, the human race and all of Earth's terrestrial ecosystems would not survive. Over 80 percent of the world's flowering plants require a pollinator to reproduce.
Wind-pollinated flowers are typically: No bright colors, special odors, or nectar. Small. Most have no petals.
Pollination happens when pollen is moved from the male to the female flowers, which triggers fruit production. When the female flowers aren't completely pollinated, the plant will abort the fruit and channel energy into other fruit production.
If this involves self-pollen, it results in inbreeding, which can result in a shrinking gene pool and unhealthy offspring.
In order to set fruit, the female parts of a flower need to be pollinated (that is, receive pollen) from the male parts of a flower. While some flowers are able to self-pollinate without the need for a different pollen source, most apples need cross-pollination to set fruits suitable for market.
- Insect-pollinated flowers are large, have brightly colored petals, are often sweetly scented, usually contain nectar- to attract insects.
- Its pollen are often sticky or spiky - to stick to the legs and body of insects.
Wind pollinated plants have small, inconspicuous or dull petals - there is no need to attract insects with bright colors. Wind pollinated plants produce a lot of pollen to increase the chances of pollination. It is also very, very light in texture, so that it is easily blown on the wind currents.
In insect-pollinated flowers, the produced pollen grains are larger in size, sticky and spiny which helps the insect to carry the pollen grains. Stigma is feathery or sticky and found hanging out of petals. Stigma is small and is situated deep inside the petals. The stamens are long and visible out of petals.
- Water pollinated plants are usually aquatic.
- They produce a large number of pollen grains as most of them get lost in the water flow and very few are able to reach the stigma.
- The stigmas of the female flower are usually above the water and are large and feathery to catch the pollen grains.
