If I do, it is when I redo an existing bed. I'm too lazy to do more often.
Whatever is there from previous at time of redo is tilled into the soil. Or
when curiosity strikes and I wonder what will happen if I try this.
If there is an easy way, I would think that to be preparing the soil in
advance, in a bed big enough to handle what ever size load the mulch comes in
and have it dumped in place. Let the mulch compost in place, then spread.
Then plant. Might take some thinkin' ahead.
That radical and world class hybridizer Moores (you know, the Lemon Chess,
under recognized Confederate Royalty, Chocolate Chess, and Gold Reprise
feller) came up with the long lost and much sought B. Y. Morrison Iris
Research Project. One facet (it attempts several) of this study evaluated a
number of different mulches on iris beds. Somewhat short term and prone to
generate more questions, it was a controlled experiment and gives a good
starting point. They evaluated black plastic covered with gravel, sawdust,
pine straw, leaves, peat moss, perlite, gin trash, plastic and no mulch.
Bottom line on the mulch facet of the report is survival is best under pine
straw and worst under sawdust.
Perhaps a greater gem is gleaned from the report data:
Under pine straw mulch Stalks per plant = 6.5, Flowers per stalk= 5.25,
plants with no bloom=0, and number of dead plants=0.
Under no mulch Stalks per plant= 5.8, Flowers/stalk=4.88, plants with no
bloom=3, and number of dead plants=4.
Thinkin' information from controlled studies is some better than
misinformation from garden lore.
Thanks to that Moores guy for information and Lemon Chess.
