How can you tell when carrots are ready to harvest?
Carrots should be ready for harvest about 60-80 days after sowing seeds, depending on the variety. The tops of the carrot roots will be about 3/4 to 1 inch in diameter and likely starting to pop out of the soil, though not necessarily. They will also be vibrant in color.
Are pine trees male or female?
Pine Cones Pine trees possess both male and female reproductive structures, or cones. Both male and female cones are on the same tree. Typically, the male cones that produce pollen are located on the lower branches of the tree.
What is the average lifespan of a pine tree?
Pines are long lived and typically reach ages of 100–1,000 years, some even more. The longest-lived is the Great Basin bristlecone pine, Pinus longaeva.
Are there male and female pine cones?
All conifers produce male and female cones. Sometimes on the same tree, sometimes not. The pinecones we see are only the female cones. The male cones are much smaller and not showy.
Why do pine cones grow at the top of the tree?
Conifers depend on the wind to reproduce, Lobdell says. In the spring, short-lived male cones produce pollen, which is carried to female cones by the breeze. Usually, male cones grow toward the bottom of the tree and female cones toward the top, which reduces the chance that a single tree will pollinate itself.
Do pinecones open and close?
The scales of seed-bearing pine cones move in response to changes in humidity. When warm and dry the pine cone opens up to release the cone’s seeds. When it is damp or cold, the scales close up. When wet the pine cones cells expand, when dried they shrink.
