This is an example although a rather sad one of why it is important to read herbicide labels and to know the difference between a brand name and the active ingredient. I was called to a pecan orchard where most of the 100+ year old trees trees had died over the winter. It is common for pecan orchards to apply glyphosate around trees to reduce w**d competition, and this is low risk when done properly. The owner of this orchard was doing the same for years using a very popular brand of glyphosate. Unfortunately this brand changed its active ingredient from glyphosate to a combination of triclopyr, fluazifop, and diquat. Triclopyr is a brush killer which outright killed most of the pecan trees and left a few damaged. The trees nearest the farm fields faired the best because of fertilizer applications that strengthened them.

Here's an update on how the sweet potato slips are developing. There are three pics to show the progression. The April 22nd planting date and pics from May 4th and today, May 11th are shown. As you can see there was really quite a jump in the last week. I stuck them outside today to give them some direct sun and start the hardening process. You can see the diversity in leaf shape and color now between the 12 varieties. You can also see that a couple varieties have not even started sprouting yet. These are all from my garden so they have not been treated to prevent sprouting. Some varieties just sprout a lot faster than others. Some already had sprouts at planting; their leaves just had to expand in the light. The biggest ones are actually ready to plant. I will probably plant in two stages to accommodate the slow sprouting varieties.

I'll be planting my sweet potato collection in a bed at the Sumter community garden this spring. That means getting my slips going, and I thought I'd show everyone how I do it. It's very easy. Clemson has a fact sheet on sweet potatoes through HGIC that I suggest checking out especially if you are new to growing this crop. The fact sheet also describes a different way of starting slips you may prefer. I'll add more pics as things grow.

See the attached pics for everything I use. I use flats with drainage holes and bottom trays since this will be in the office rather than a greenhouse. The front of each tray is marked with a number which refers to a listing in my notes of what three varieties are in each tray and in what order. I also try to make sure the varieties next to each other are different enough to help keep them separate (leaf shape and leaf color). I just use ordinary potting mix and don't worry about fertilizer. There's no need to cover the roots completely.

I maintain 12 varieties with diverse characteristics (root skin color, root flesh color, leaf color, leaf shape, and vine length). Some may not realize the diversity out there. If you don't have much space, there are varieties with vines only three feet long. Flesh colors are shades of orange, yellow, white, and purple. Skin color can be white, yellow, tan, red, orange, and purple. They also store for six months or longer at room temperature. I store mine in a closet.
