    I was wondering if there is a set or base line amount of flats to cover 100sq ft of bed.
    I'm refering to the normal flats 36 plants I think.
    I have a customer that has an area about 250sq ft and would like to give her an est. also is there an avg chrg per flat,no admendments just planting chrg.
    Thanks for any help

    What are you planting? Some plants should be 6-8" apart, some should be 12". Just read the label on the plant & figure it out yourself using pencil & paper how many you'll need to cover the area.


    plant 6" apart = 1 plant / 36 sq inches
    plant 8" apart = 1 plant / 64 sq.inches
    plant 12" apart = 1 plant / 144 sq.inches

    so for your 250 sq feet, if you planted something that shouold be spaced every 8 inches...

    250sqft = 36000 sq inches
    36000 divided by 64 = 140 plants



    What I charge to plant "a flat" depends...

    On what I'm planting in (is the dirt hardpan/clay, or nice fluffy/mulchy/loam)takes LOTS longer to plant in clay.

    They almost always need amendments & fertilizer (YMMV), so I almost always add that (if they really need it, I just tell 'em they HAVE to do it - I have to see stuff I've planted not grow or die (then they're mad at me)

    Is it in an easy-to work in flower bed, or a planter next to their pool (where dirt spillage will be NOTICED!) Boy did THAT job take longer than I planned!

    On what size I'm planting (6-packs of color; 4"pots; a soggy flat of too-small Impatiens from HomeDepot) all will be priced accordingly.

    I start around $20-25 per flat & go up or down depending on my best guesstimate on how long it will take me. Then I charge more 'cuz I usually understimate.

    Hope this helps.

    I think I can work with that info..more than I had.
    I was mainly talking about Pansy and the smaller mass type plantings..but as you stated just look at the recommended spacing.
    also this was leading to the 1st question...is it ok to crowed an annual bed if they will be removed every 3 months or so? thats what I wanted to get to..down here it looks as though the pansy beds are as tight as the flats.
    Thanks

    Dennis,
    Don`t go less than 6in. on pansies,they spread fast.If you keep them deadheaded they should last longer than 3 mos.Be careful planting them in ga. when it turns warmer unless they are in partial shade.

    Here's A Ground Cover Chart You may want to use from time to time:

    Inches on center...............Conversion Code
    4"............................. 9
    6"............................. 5.75
    7"............................. 3
    8"............................. 2.6
    9"............................. 1.75
    10"............................ 1.66
    11"............................ 1.2
    12"............................ 1.15
    13"............................ 0.85
    14"............................ 0.73
    15"............................ 0.738
    16"............................ 0.64
    17"............................ 0.5
    18"............................ 0.512
    19"............................ 0.4
    20"............................ 0.36
    21"............................ .33
    22"............................ 0.3
    24"............................ 0.29

    Example:
    Plants @ 8" O.C.
    250 sf X 2.6 = 650 X .80 = 520 total plants needed
    if you use the .80 it will allow for a 20% set back
    from edges,etc.

    Clinton - thanks for the chart, but is it correct?


    I'm thinking about the 6 inch spacing. If I'm planting one square foot, I'm putting in 4 plants. Picture starting in the lower left corner... one there, then one (6 inches) to the right, then two above them.

    (this calculation works if you expand it out into any large planting, say 16 ft X 16 ft)


    If you planted all corners of the square, then the number would be nine (with all plants at the corners).


    If they are spaced 3" in from the edges, the number is again 4.


    Where does 6.75 come from?


    (don't know how to post a draawing, or I'd show ya)

    Sorry about that...this one is right...
    left out the 5" and used the 5.75 for the 6"
    long night...
    Inches on center...............Conversion Code
    4"............................. 9
    5"............................. 5.75
    6"............................. 4.6
    7"............................. 3

    9"............................. 1.75
    10"............................ 1.66
    11"............................ 1.2
    12"............................ 1.15
    13"............................ 0.85
    14"............................ 0.73
    15"............................ 0.738
    16"............................ 0.64
    17"............................ 0.5
    18"............................ 0.512
    19"............................ 0.4
    20"............................ 0.36
    21"............................ .33
    22"............................ 0.3
    24"............................ 0.29

    <b>Will Johnson....</b>
    maybe this will explain how I come<br>
    up with the QTY's for plants.<br>
    first note that we also use a 20%<br>
    set back for all planting OR .80<br>
    I have never seen an area that did'nt<br>
    have A boarder around it...<br>
    and we would'nt want to plant on it<br>
    so we alway's set back from it.<br>
    if GC is to be plant on 6" center then<br>
    we use 3"set back, if 12" o.c. then<br>
    6" set back and so-on.<br>

    <b>Here is a chart for example:</b><br>
    [​IMG]
    Note the chart shows 60 plants per the 4' x 4' area
    60 plants x 16 sq's= 960 plants you would need
    so..if we buy 40 flats x 24 = we would get the 960 plants
    we needed.

    This is not intended to replace any personal skills or information you may
    be using now. It is only intended to help you with your judgement.<br>
    <b>P.S....</b>if the chart does'nt show up you can go to my site I have<br>
    it at the bottom of the page for a few days...<br>

    KIND gardener says 140 plants
