Benefits of Pruning Peppers: Several Examples with Control Plants

Benefits of Pruning Peppers: 

Several Examples with Control Plants

There are several reasons you may prune peppers. One reason is to develop stronger sturdier stems. This helps plants manage high wind areas and better support heavy crops of peppers. Removing the main growing tip will also create more side-shoot growth in 98% of pepper varieties. I found a few that don't seem to like pruning like 'Banana' peppers. This will create a bushier plant that will branch out and flower more.  The more flowers, the greater the yield of peppers.

Pruning ultimately lets you make a stronger plant that produces more. I will be doing an ongoing series based on the peppers I am pruning. I will be using control groups when available. Here is what my original pruned peppers look like, about 1 month later after their initial pruning. They are compared to un-pruned peppers of the same variety.

Here is the original pruning video if you would like to see how it is done. Pruning can be done many many many ways. This is just one way that I prefer.

If you are growing peppers indoors it is important to know when to transplant them outdoors or into larger cups/pots. Peppers really like warmth and should go out in the garden when the temperatures no longer get below 50 degrees F. If they are in cups, transplant them when they look like this...

Purple (Not really) Bitter Cress (Cardamine douglassii)

Cardamine douglassii (04/08/15)
Durham Co., NC

Cardamine douglassii is sometimes called Limestone Bitter Cress, or Purple Bitter Cress. Neither name seems to be that appropriate (but common names rarely are),  First, it only rarely (maybe never?) grows directly on exposed limestone, and certainly never does so in NC. Second, the flowers are rarely purple, but nearly always appear pure white (but see below). For these provincial reasons, I prefer to call it "Douglas's Bitter Cress".

Douglas's Bittercress is another plant species with restricted distribution in North Carolina, and which seems to be most abundant or widespread in the mid-western United States.  In North Carolina it occurs only in a few Piedmont counties, including Durham & Granville; these locations and the those in the Virginia Piedmont are significantly disjunct from the nearest populations to the west.  The habitat where I have observed the species is infrequently flooded floodplain forests. One of the sites supporting the species is shown below:

Like other Bitter Cress species, Cardamine douglassii is part of the Mustard or Brassicaceae family and produces slender tubular seed capsules, or "siliques", that are much longer than wide.

Stems usually lack leaves for most of their length. Several accounts from other states indicate stems are hairy, but I have not observed that in North Carolina. Cauline leaves are usually found on the lower third of the stem, unlobed and usually toothed. Basal leaves are more heart shaped. Younger, non-flowering plants of these perennials produce only rounded leaves

Fortunately, the species seems to require little in the way of active management.  Localized threats to populations in North Carolina include construction & maintenance of water and sewer easements. installation of waterfowl impoundments, beaver flooding, and competition with invasive exotics, especially Japanese Honeysuckle.

Plum Thicket Part 1, American Plum

Durham Co., NC April 15, 2015

American Plum (Prunus americana) occurs in scattered localities across the North Carolina Piedmont & Mountains but is generally absent or infrequent in the coastal plain.  Wide ranging across North America, it may have been cultivated by some Native Americans (see Havard 1895 in Bulletin of Torrey Botanical Club)

Showy, white, highly aromatic flowers develop before the leaves, and before most other deciduous species have leafed out in our area.

American Plum is infamous for forming dense thickets in certain open habitats. These thickets are due, in part, to its propensity to root sprout.  In the example shown here, sprouts are 3-5' tall and leafed out more fully than nearby mature trees, but no flowers were produced. Most have developed 10' or more from the main trunk and appear to be "invading" the open area, with the shortest sprouts along the leading edge.






The origin of these sprouts appear to be large Prunus americana individuals with well developed, widely spreading, and drooping branches, above twisted,multi-trunked stems. These small trees (see images following) produce significant masses of flowers. Interestingly, the space around the trunk(s) is clear of sprouts and other woody plants, possibly due to the density of the canopy or the species may be allelopathic.

The following sequence illustrates progressive stem development.
