Trees

Yes, the jacaranda tree can be toxic to children and pets. The Food and Drug Administration includes the tree in its database of toxic plants even though sources such as the American Society for Protection Against Cruelty to Animals (APSCA) and studies such as by the University of Hawaii indicate otherwise. The Mountain Woodworker keeps a list of woods that are toxic to woodworkers, and the jacaranda tree shows up as provoking asthma and dermatitis.

Whenever we travel by a fast running vehicle, the standing objects appear to be running fast. The appearance of their fast racing is described as 'sprinting'. So, the young trees described as sprinting. They provide a stark contrast to the passive old lady sitting inside the car.

A tree is one tree and a forest is many trees.

The Kaingin System refers to the burning of trees for cultivation purposes.

Kaingeros cultivate the area until such time that the soil is no longer good for planting. Then, they transfer to another area and burn the forest again.

Yes, they do but this depends a little on the variety and how the tree is managed. They tend to bear more heavily on alternate years, but this can be helped by thinning the crop quite a lot in the heavy-bearing year. Some varieties are prone to produce more in one year than another. You will still harvest some nuts each year, just less in one of them.

Years ago there was a song by Tony Orlando & Dawn asking someone to "tie a yellow ribbon 'round the old oak tree" if she still had feelings for the man who had been away for an extended time.

The practice became associated with men away at war. The yellow ribbon became a symbol of support for the troops.

Fertilize your young avocado trees with ½ to 1 pound of actual nitrogen per tree per year. You can spread it out over several applications as long as it totals ½ to 1 pound of nitrogen. The other important nutrient for avocado trees is zinc. Ordinary home fertilizer for houseplants will normally work.

Trees are vascular and ferns not

yes its pholrite-petrofide rock .Not just phonite porphry-clunker stone. the Indians kill scientist if they told place was special. they knew no gold was in so its still there!

While I'm no botanist, I am working with poinciana and jacaranda seedlings. Through observation, I can give you what I believe is an exceptionally sound opinion based on a number of different observed facts.

1. The Jacaranda creates roundish seed pods as your zone'd weather begins to warm. These pods start out closed, hanging like odd little wooden ornaments. Over time, between moisture, rising temperatures, then drying, these pods split open while still on the tree, or they fall to the ground where they appear like a slightly opened clam.

2. Inside these pods are anywhere from 20-50 or more seeds with a super fine paper like substance surrounding the harder wood of the seed.

3. Once they are partially opened while still on the tree, or once they hit the ground, the seeds are very very light and in a windy day, the seeds will either be blown out and around. On the ground, these pods generally get fragile quicker and will fall into two halves where again, the seeds are moved by the wind.

4. As for substantial distances, I can't say how, as I don't suspect birds would eat them, though maybe in their natural habitat they do, but even still, based on what I've seen of their growing habits, I doubt that a seed would remain viable if eaten, digested and excreted....but maybe others know better.

5. It's possible on a windy day for these seeds to be carried or tumble a good distance depending on where they are released, and assuming they don't come to rest against something that will cause them to stop moving.

6. The other method is that the super fine papery like "wings" stick to animals paws if stepped on or they can simply land on the back of a mammal and eventually come to rest where they do.

7. As for how they found their way from their indigenous location to the many non-native locations that you find these trees today....it's like every other non-native plant...it either traveled in an agriculture or livestock shipment, or were deliberately collected for transplant as I did (from around the corner :).

The seed coats are a bit tough, but I found that unlike the poinciana, which will never sprout unless the SUPER hard casing is stratified or nicked followed by a good deal of water absorption into the casing, these seeds simply need soil and moisture to sprout and as best I can tell they have no trouble germinating once properly placed. I soaked 20 seeds in tap water overnight, planted two each in a 10 segment seedling tray and after keeping the soil fairly moist with only limited indirect sun exposure, and temps above 75-90 during the day and mid 50's to 60's at night, I had 19 of the 20 germinate, and I suspect the only reason I didn't have 100% was because I found one of the seeds next to the pod (not in soil) and only just now placed it back in the soil two days ago. I full expect to see this seed germinate in another 10 days or so...

Probably a little more in depth than you were interested in, but I thought I'd share. :-)

Poplar Trees

most spring blooming shrubs require pruning after the blooms are gone, but before fall.

no it will catch a your house on fire

Corylus avellana the hazelnut tree.

Used coffee grounds are a great soil amendment. High in acid they are fine for dogwood trees. Most insects do not like coffee grounds and will avoid them, so spreading coffee grounds around a dogwood will also help rid you plant of over wintering leaf eating insects.

gran chaco

Yes.

The Hawaiian tree you are referring to is the kukui tree, also known as the candlenut tree (Aleurites molucanna). Its branches produce long, hanging tendrils that can develop into roots upon contacting the ground, allowing the tree to stabilize itself in the soil. This adaptation helps the tree thrive in its native environment. The kukui tree is also significant in Hawaiian culture, symbolizing enlightenment and protection.

The red cedar tree, specifically the Western Red Cedar (Thuja plicata), primarily grows in the coastal regions of Washington state. It thrives in the wet, temperate rainforests of the Olympic Peninsula and the western parts of the Cascades. This tree is often found in lowland areas and along riverbanks, favoring moist, well-drained soils.

A tuft of flowers on a willow or hazel tree refers to the clusters of catkins that these trees produce. Catkins are cylindrical flower clusters that appear in the spring and are typically pollen-bearing, playing a crucial role in reproduction. In willows, they can be soft and fuzzy, while hazel catkins are often long and slender. These tufts are important for attracting pollinators and are a key feature of these trees during their flowering season.

Beech trees have several adaptations that help them thrive in diverse environments. Their smooth, gray bark protects them from pests and diseases while allowing moisture retention. The broad, dense canopy enables effective light capture, essential for photosynthesis, and their shallow, fibrous root system helps absorb nutrients efficiently. Additionally, beech trees produce abundant seeds, which support wildlife and promote regeneration in suitable habitats.

Evergreen trees, like all diploid organisms, typically have two sets of chromosomes, one inherited from each parent. This means they are diploid (2n) and possess a complete set of genetic information, which is crucial for their growth and reproduction. The specific number of chromosomes can vary significantly between species of evergreen trees. For example, the Norway spruce (Picea abies) has 24 chromosomes, while the Eastern white pine (Pinus strobus) has 24 chromosomes as well, showcasing the diversity within this group.
