Horticulture 101 – Class Notes

Here are my notes from class and things I’ve learned which might be helpful to myself and others.

Bring a backpack, #2 pencil and a hat. For labs you will have to leave the classroom so you may want to leave laptops home that day.

  • The books for this class are expensive! This class costs $392 for a four credit class.  The two required books cost $321! Amazon does have the one book cheaper at $133 and I found a prior edition from bn.com for $10. You can guess which one I bought.
  • The syllabus I was given says that “older editions will work.” That’s a good tip to remember – talk to the professor, before you buy your books and find out what his suggestions are with regards to books.
  • This article seems to indicate that the publishing industry seems to be gouging the college student these days.
  • You can also rent some textbooks these days which would be cheaper.
  • You can also look at textbooks.com – chegg.com http://www.thebookczars.com/ – half.com for class books. Also the Mobius Catalog allows you to borrow books. Abesbooks.com also. And BetterWordBooks.com
  • Jan was filling in. She’s the greenhouse manager.
  • Generally they use liquid fertilizer – around a 1 to 100 ratio.
  • They use a systemic pesticide with their poinsettia – I wonder if they use that with all their plants.
  • For home use she likes long term osmocote, but says that because of the hot summers that osmocote will only last half the indicated time.

  • They use Pestraps in the greenhouses. It’s very sticky. You can buy them at Hummerts. They have different sizes.

        • They use coarse sand as a medium to propagate cuttings. They do misting to keep the plants moist since the roots haven’t formed.

August 22 Class Below

Botany is the study of plants

Science and scientific method

Experimentation – Observation – Verification and discarding of information.

Ask a question – formulate a hypothesis – perform experiments – develop a theory/conclusion

Plant physiology – study of plant function – how they conduct materials internally

Plant morphology – study of structure and form of plant – how it changes over its life span

Plant anatomy – inner structure of plants

Plant taxonomy – classification of plants

Family – Aceraceae (capital A)
-Genus – Acer (Capital A and all Italics
species (lower case) italics
– Cultivars/varieties – regular lettering

Trees – Roots – Mulch Discussion

Most of the roots of a plant only go down 18 inches.
On a tree you want to be able to see the root flair. That’s the curve at the base.
On most trees you buy the root flair will be covered.
You need to take off the top layer of dirt so that you can see the flair/curve.

To go in and add a layer of top soil on top of tree roots will smother the roots.
The volcano of mulch around a tree prevents water from getting to the soil.
You only need an inch of mulch around a tree and plants.
You don’t need mulch around a mature tree.

BT Genes are in corn – called BT Corn

Apparently some corn is still being infected.

10 crops that feed 80% of the world.
rice, wheat, corn,

sorghum, beans/peas, cassava,

Don’t do mono-cultures in your gardening.
Trees and plants can get wiped out.
All the ash trees on the arch grounds are going to die because of ash borer.
They only plant one variety.
Apparently they are going to make the same mistake again in the new plans.

Here’s an article – http://goo.gl/W3HNV5

Photosynthesis
Sunlight + water + CO2 = energy + sugar + Oxygen

Pg 284 – Five Kingdoms
Bacteria – single cell – break stuff down.

Prefers to use the word SOIL – not dirt
