Question: Planting Vegetable Seeds, Nematodes, How To Propagate Copperleafs

This week's email:
Jayne has two questions.
You have a great program on WLBE !!! One thing that confuses me is when you recommend vegetable and flower plantings, I'm not sure if you're talking about sowing seeds or planting transplants. I usually grow everything from seed, so I'm looking for that time table.
Your email is a very common problem here in Florida - thank you for writing and the kind words about "In Your Backyard." 

You want to plant seeds approximately 14 to 28 days (depending on species) before you want to transplant them in your garden. When I talk about vegetables this time of the year, I mean that you should either purchase or use your transplants that you seeded in July and August.

Tomatoes planted from seed 5 weeks ago.

Five different species of peppers planted August 27th.

I brought my weird looking carrots into the extension office in Tavares and was told I had nematodes in my 12 ft. square foot garden (3 ft. off the ground). I also had green and yellow bush beans that didn't do well at all, but onions and shallots doing great! It has only been the second season of growing crops in this garden and I am so dissappointed. Do I need to kill the nematodes before planting again? If not, what vegetables would you suggest? If I need to kill the nematodes, how do I do that? I grow, eat, live, organically. 
Jayne, I'm so sorry!  Certain plant species release alleopathic chemicals that make growing some species next to others very troublesome.  Check out this great chart of compatible and incompatible garden plants.  I think it will help explain why some of your plants didn't do well.

Also, because of Florida's sandy soils in certain locations, destructive nematodes are a vegetable gardening problem. The key to controlling nematodes will be with your cultural practices.  Jayne, you can do one or all of the following:
  1. Change out or sterilize your vegetable garden area with solarization next spring before you plant for the summer.
  2. Add amendments to your soils, which will allow beneficial fungi to control nematodes.
  3. Add beneficial nematodes to your soil which will provide about three months of control against root-knot nematodes
  4. Buy nematode-resistant plant varieties. Look for the N in plant description (V = virus-resistant, F=fungal-resistant, N=nematode-resistant)
  5. Rotate your crops. Don't plant carrots or plants in the same family (tomato and peppers) in same location year after year.
  6. Last but the best way to grow vegetables in Florida's sandy soils? Raised beds -whether you build them yourself, use containers, or purchase a kit.

Roberto asks:
Can you explain to me how to take a clipping from one of my existing Copper Leaf plants and use it to grow another plant?
Roberto, easy way to get more plants! Take a cutting of a soft tip of a stem of copperleaf approximately 5 to 6 inches. Cut the stem diagonally and place in Root-tone and then plant in potting soil. Moisten and keep moist (not wet) and in the shade. You can put the plant and pot into a clear plastic bag to keep the humidity in. Within six to eight weeks you'll have roots and can repot into a bigger pot. I would wait until spring before putting them in the ground as its so close to winter.

Here's more information with photos.

These are Cotinus coggygria 'Royal Purple' Smoke Tree cuttings that I took about four months ago.
