I wonder why it is that some plants become annuals and others perennials?

Now, if it does not decay biologically, it shifts to oxidation, which is a very slow process, and this smothers and kills grasses,

What is the best thing about your home state? gt gt Japanese Student

Vegetation

And there'll be advantages for spreading out long, sort of kelp like forest of vegetation.

Every blade of grass.

But, in fact, they're grassland habitats for grassland birds and plants.

These plants are resistant to weed killers.

Plants grow.

And when seedlings grow to this size we separate them apart, we plant them here.

Weeds sprang up in the garden.

It's fine.

A weedlike vine found only on lego,

Well, he goes on to tell me it's such a rich system that the fish are eating what they'd be eating in the wild.

They don't have roots that go into trunks nor to the forest floor.

That you can go from this zero situation, by planting the vegetables and the trees, or directly, the trees in the lines in that grass there, putting up the buffer zone, producing your compost, and then making sure that at every stage of that up growing forest there are crops that can be used.

Your ass is grass, Matthew.

But my passion in addition to Jack and my children are the plants, the so called epiphytes, those plants that grow up on trees.

(Laughter)

Organisms don't think of CO2 as a poison.

I mean literally wrote the book on Pandoran botany.

There is no grass on the moon.

There is no grass on the moon.

I had the gardener plant some trees.

Oh, the seedlings taken from the seedbed will be planted to the paddy?

And the tissue's very expensive.

Trees do not grow on prairies.

I was born on the Steppe...

That's why there are always weeds this way?

Where there is grass, there is no water. Where there is water, there is no grass.

This is our paleobotanist, Dr...

One of 'em makes people glow in the dark.

Cows live on grass.

You know, if you're interested in plants you'd be better off with Goshawk's Guide to Herbology.

But then I realized, No, this is exactly what the grasses want us to do.

What we had failed to understand was that these seasonal humidity environments of the world, the soil and the vegetation developed with very large numbers of grazing animals, and that these grazing animals developed with ferocious pack hunting predators.

As it's gotten warmer on the top of the mountain, the vegetation zone is actually changing.

So here's the next challenge.

The garden was grown over with weeds.

The garden was overgrown with weeds.

And watch the change as it goes into this long dry season.

She smokes 20 cigarettes a day.

I remember reading something in Herbology.

The weeds then are dying, after completing their life, so we don't care.

Fungi married algae ... clinging to rock, and eating it too ... transforming barren land. True land plants arose, leafless at first.
