I recently attending a workshop sponsored by Urban Harvest.

The workshop covered topics on how to increase your success of propagating plants using cutting and seeds.

My need for attending workshop involves increasing my success with growing milkweed from plant cuttings and seeds.

Simple rules for successful propagation from plant cuttings:

1.  Use good moist planting soil.   The key here is moist.   Plant in a small pot or as desired.

2.   Depending on the plant and hard wood, the cutting may require a root hormone powder to increase root

          growth.   Many plants do not need this treatment

3.   Use an object just larger than the cutting to provide a hole for the cutting.   The larger hold helps

         prevent loosing some of the rooting hormone as the cutting is inserted into the soil.

4.   Be sure and strip leaves from the bottom and leave nodes where roots should grow.  Be sure to remove

          the growing tip by clipping it off.

5.   Pat down the soil around where you have made and give it a little water.

6.   At this point you can add and pat down a little vercumlite to help retain moisture.

7.   Then take a plastic zip lock bag and you will slide this over plant.  Make it tight so it will have a seal and

        moisture can be retained.   Use some plastic straws to keep the bag from following down on the newly

         planted cutting.

8.     Place in a nice warm and wait for plants to root.

Propagating seeds:

1.      Use a small pot and fill with moist soil.

2.      Follow basic guidelines on how to create little green houses.

3.      Select your seeds

4.      Cover seeds with correct depth of soil.

5.      Cover with a thin amount of vercumulite.

6.       Water

7.        Take the zip lock bag as used before and cover pot to retain moisture.

Step 4 question

I have a question about Step number 4. "Be sure to remove the growing tip by clipping it off." Does that mean to make a fresh cut in the bottom end?

All our HW Master Naturalists start your plantings. I am thinking about a Pollinator Fun Day at Jones Forest on June 23. We could use some donated plants for give away, teaching, or a fundraiser sale. ---Ash

Remove the growing tip

This means the new growth, cut off opposite end from where you cut fr main plant.

Growth tip

Something that I've never thought about. I usually just cut the top part off branch and attempt to root. Apparently the top part of cutting is in growth mode. The way I understand it, the top part would continue growing and pull energy away from the cutting which should be putting all it's energy into making roots. Basically it is like pinching ends to encourage growth. Wonder if learning to progate would an interesting topic for a garden morning at Jones. Learn to make cuttings of your favorite plants from Jones garden. People could bring cuttings from their gardens and pot up for pollinator fest. Hope that helps, Linda

When to propagate plants?

When is it best to propagate plants? Spring or fall? Summer?

best time to propagate is year round in are area

From the training I received it sounded like year round was okay time to propagate plants.

Though it sounds like sometimes will be easier, such as spring when the new growth is occurring.

If extreme temperatures and wrong plants it would make it very challenging to have success.

Right now is a good time to play with and experiment with propagating plants since we are getting new spring growth.

Just remember to clip the growth tip of any cutting you are trying to root.   Cutting will need several nodes on stem to grow plants.  Remove any excessive leaves.   Place plastic baggie or cover over the pot to retain moisture.   Use rooting hormone for increased success, however some plants don't require the rooting hormone and thus it would be a waste.  Clip excessive leaves from cuttings.  Use straws or something similar to keep plastic bag from touching cuttings leaves.  Use a plastic knife or popscicle stick to create a marker for what the cutting is.  I have also found a permanent marker used to write on plastic bag is also a good way to identify cutting and date of planting.   However, plastic bags tend to get shuffled,  so having a plant marking stick is the best option.

Leaving the growth tip draws energy from the plant to try to grow bigger leaves when initially you want a cutting putting as much energy as possible into growing roots.

Good luck and best wishes on successes on propagating your favorite plants and new favorites.
