Ferns are reproduced from spores that are gathered in clusters called sori, which are usually on the underside of the fronds. The spores can be yellow, green, brown, or black. Look around your garden or the woods to see if you can find spores.
Supplies
Ferns with spores
Knife
Piece of paper
Pot
Potting soil
Gallon ziploc bag
Let's Do It!
July in North Carolina is a great time to find a fern with spores. Go into your garden or find a friend with a fern.
Flip the fern leaf over to reveal spores on the underside.
Using a knife, gently (and carefully!) scrape spores from the leaf onto a piece of white paper.
Fill a pot with potting soil.
Moisten the potting soil.
Sprinkle the spores from the paper onto the soil surface.
Put the pot into the plastic bag and place in indirect light.
Watch as new ferns will slowly emerge!

Learn how to take stem cuttings from your favorite landscape shrubs and root them at home! Propagation by stem cuttings is the most commonly used method to propagate many woody ornamental plants. Stem cuttings of many favorite shrubs are quite easy to root.
Supplies:
Sharp pruning shears
Pot
Potting soil
Rooting hormone (optional)
Gallon ziploc bag

Determine which plants you are interested in taking a cutting from. Check to see if the timing is right to take a cutting of your plant. This NC State Extension factsheet lists many ornamentals and what stage the plant should be in for the cutting.
Cuttings should generally consist of the current or past season’s growth. Avoid material with flower buds if possible. Remove any flowers and flower buds when preparing cuttings so the cutting’s energy can be used in producing new roots rather than flowers.
Take cuttings from healthy, disease-free plants, preferably from the upper part of the plant.
Cuttings from lateral shoots often root better than cuttings from terminal shoots.
Early morning is the best time to take cuttings, because the plant is fully turgid.
While terminal parts of the stem are best, a long shoot can be divided into several cuttings. Cuttings are generally 4 to 6 inches long.
Remove the leaves from the lower one-third to one-half of the cutting .
On large-leafed plants, the remaining leaves may be cut in half to reduce water loss and conserve space.
Treating cuttings with root-promoting compounds can be a valuable tool in stimulating rooting of some plants that might otherwise be difficult to root.
The rooting medium should be sterile, low in fertility, and well-drained to provide sufficient aeration. It should also retain enough moisture so that watering does not have to be done too frequently. Materials commonly used are coarse sand, a mixture of one part peat and one part perlite (by volume), or one part peat and one part sand (by volume).
Insert the cuttings one-third to one-half their length into the medium. Space cuttings just far enough apart to allow all leaves to receive sunlight.
Cover the cuttings with plastic and place in indirect light. Avoid direct sun.
Keep the medium moist until the cuttings have rooted. Rooting will be improved if the cuttings are misted on a regular basis.
Rooting time varies with the type of cutting, the species being rooted, and environmental conditions. Conifers require more time than broadleaf plants. Late fall or early winter is a good time to root conifers. Once rooted, they may be left in the rooting structure until spring.
Do you or a neighbor have asiatic lilies growing in the garden? Dig just one up and you can end up making new plants from each lily bulb scale.
Supplies
Asiatic lily bulb - from your garden or local nursery
Bleach - safety note: be careful when handling, avoid contact with your skin
Vermiculite
Gallon ziploc bag
Let's Do it!
Dig up a lily bulb from your garden with permission or obtain one from a mail-order nursery or your local nursery.
A lily is made up of scales attached to a basal plate where the bulb roots are formed. To scale a bulb, the overlapping scales are broken off at the base and not in the middle.
Pulled back gently on each scale and give it a slight twist so it will break cleanly away at the basal plate.
Take the first and possibly second row of scales (if bulb is large enough) and plant the remainder of the bulb back in the garden.
Soak scales in a 10 % bleach solution: 1 part bleach to 9 parts of water. Let them soak for about 10 minutes.
Rinse the scales off with cool running water.
Put your a cup or so of vermiculite into a plastic ziploc bag and lightly moisten it.
Add your scales into the vermiculite and place in a dark place for a month or so.
Once the scales have started to root, plant them ½ inch deep in potting mix.
How long do you think it takes to remove the seed coat of Kentucky coffeetree seeds?
Kentucky Coffeetree seeds have a very thick seed coat that take a long time to break down in nature before a seed can germinate. What do you think will happen if you plant a Kentucky coffeetree seed? Will it grow? This is an experiment to find out!
Some seeds have really hard seed coats that protect them from germinating at the wrong time -- times when it might be too cold, too wet, or too dry. Tough seed coats can also protect seeds when they have been eaten by animals and go through their digestive tract.
2 Kentucky Coffeetree seeds
Metal hand file (not a nail file)
2 Pots
Potting soil
Fill your two pots to the top with potting soil.
Label one pot, "Control," and the other pot, "Treated."
Take one Kentucky coffeetree seed and plant them about 1-inch deep in the "control" pot.
Take the remaining seed and rub them on the file until you can see a small bit of seed. The seed coat is thick, so this might take some time. Be careful not to rub your fingers on the file.
Once you have nicked the seed coat of the seed, plant them 1-inch deep in the "treated" pot.
Water the pots until the potting soil is moist.
Place the pots in a sunny location and water as needed, likely every day.
Make a prediction about which seeds will germinate first.
What happened? Which seeds germinated first, "control" or "treated?"
Was your prediction right or wrong?
How long did it take for the seeds to germinate? Did all of the seeds germinate?
Where does Kentucky coffeetree usually grow? Why might it be important to the environment?
What are you going to do with the plants that germinated? How big do these trees get?
What other seeds need "treatment" to germinate?
You don’t have Kentucky coffeetree seeds? No problem. Use morning glory seeds instead.
Experiment to determine the best scarification method: hot water, sandpaper, vinegar and a control.
What did you find out? How long did it take for the seeds to germinate? Which treatment worked best?

Plant propagation is the process of producing a new plant from an existing one. It is both art and science requiring knowledge, skill, manual dexterity, and experience for success. To understand the science of why, when, and how to propagate requires basic knowledge of plant growth and development, plant anatomy and morphology, and plant physiology.
NC State's Extension Master Gardener program has a full chapter for you to read on propagation.
