Late First Planting New Square Foot Raised Beds

Here in the Philadelphia area, it is customary to plant peas and onions on St. Patrick's Day, 17 March. My two new raised beds were still in the planning stage on that date. I finished constructing, mixing the planting medium and filling the beds 15 April. Too late to plant peas and onions. Not to late for tender plants if they are protected from frost.

Lowe's had these Bonnie tomato plants on sale 20 April. Besides being on sale, they were tomato varieties I wanted to plant. One thing about Bonnie plants I have learned over the last few years is that the variety you want may not be available if you wait to make your purchase later in the season. For those two reasons I purchased the following four tomato plants.


Red Beefsteak-My wife's request
Mortgage Lifter - A huge tomato with great taste
Mr. Stripey - A buttery sandwich size tomato
Tamy G Hybrid Grape Tomato- I have never grown it but will give it a try










In the past I have failed to get the newly purchased plants into the ground before they suffered damage. I tend to procrastinate. Therefore, as soon as I got these plants home from Lowe's, I prepared the grid and started planting the tomatoes.


Each tomato plant got its own one foot square. I cut an X in the center of a square. I folded back each triangular flap to form a square. I then dug down to near the bottom of the raised bed, putting the displaced growing medium on the plastic mulch near the hole.


Using my thumbnail I removed branches about 6"/ 15cm up from the bottom of the stem. Why do this? Tomatoes sprout roots along the buried stem. The extra roots add support for the fruit. Plus, the tomato will access moisture deep in the soil that doesn't dry out as readily as soil near the surface.


Next I removed the label and pot from the growing medium and tomato roots.


If the roots are dense and growing in a circular pattern, 


they must be loosened, straightened, freed from that circular pattern. If you don't, the roots will continue to grow in that same circular pattern and not stretch out for support and access to more moisture.


Place the plant into the hole, roots first, of course. The bottom branches of the plant should not touch the plastic mulch when the plant is standing straight. If they do, remove those lower branches.


Return all of the displaced growing medium into the hole around the plant and firm it down a bit. Move on to the next plant and repeat. 

Besides the tender tomatoes I also planted seeds of several varieties of lettuce and several varieties of carrots in the raised bed.


The four squares on the bottom row are each planted with four lettuce each. The two squares on the left side of the next row each has 16 carrots spaced equally.

For a continued supply of lettuce, I will plant more every two weeks until the temperature gets hot when the lettuce tends to bolt to seed. I reserved some squares for peppers and other tender plants to be added at a later date.

Raised Bed Growing Medium Recipe

Traditionally the growing medium for plants has been soil, dirt, earth, ground, loam or what ever you to call it in your neck of the woods. The composition and structure of soil can vary widely from place to place. To take the guess work out of the composition and structure of your local soil it may be better to create your own growing medium. Start from scratch. Play God a little bit.


According to the original Square Foot Gardening by Mel Bartholomew, the growing medium consists of: 

  1. Sphagnum Peat Moss
  2. Mushroom Compost
  3. Vermiculite
Also recommended are organic sources of nutrients. Above you see:
  1. Blood Meal
  2. Bone Meal
  3. Wood Ash for which I substituted Green Sand
In the photograph is enough peat, compost and vermiculite to fill two 4' x 4' x 1' / 1.2m x 1.2m x .3 m raised bed. That is 32cu ft/ .9cu m of material.

To start mixing the medium I dumped two bails of sphagnum peat moss onto the patio. The peat is very dry and light in weight. I then added three bags of mushroom compost to the pile. This bagged mushroom compost is almost wet and very heavy. Then it was time to mix the two together.

Using a square mouth shovel, slide the shovel under the close edge of the pile and place the shovelful atop the pile. Continue that action moving the pile away from you. The clumps of compost and peat will fall from the top of the pile and settle at the edge. Smash those clumps with the flat of the shovel to make small pieces of the large.

Be sure to move all the mixture in the pile and not leave any concentrations of components.

Once the medium is homogeneous add one bag of vermiculite. 

Using the same shoveling technique, mix the vermiculite until the medium is again homogeneous.

Add 1gal/ 3.78L of green sand and mix again.

The next step will take some time. Add water to the medium. Shower the pile with water. 

Both the peat and vermiculite will absorb a great amount of water. Use the same shoveling method as before to mix the water into the medium.

The medium will have enough water when squeezed 

it holds together in a clump. The mixing is finished.

It feels good to create.

First Planting 2012 Square Foot Garden Plot

My original plan was to plant by 17 March 2012.  That didn't happen.

On 18 March, I placed seeds into plastic sandwich bags along with damp paper towels to begin germination atop my refrigerator.
Why the top of my refrigerator?  The process of refrigeration involves warm air.  Warm air is blown from the bottom of the refrigerator up the back and exits across the top.   I placed the seeds I wished to germinate atop the refrigerator to take advantage of the exiting warm air.
17 days later, the seeds had germinated.  Each bag was labeled with the contents - vegetable, name, days to fruit and germination start date.

You can see the roots have grown through to the other side of the paper towel.  Not something I wanted to happen.  I had waited 17 days.  What did I expect?  Of course the roots would be long after 17 days.


I originally wanted to use unbleached coffee filters, for two reasons-
  1. No bleach would be present that might damage the seedlings
  2. The paper of the filters is less porous, not allowing the roots to grow through the paper
Alas, the day I started the germination project, I had no coffee filters in the house.  I made due with what I had, paper towels.

4 April 2012 and I was ready to plant my seeds in the square foot plot.  I began with the following supplies - 
  1. a 10 qt /9.5 l bag of organic seed starting mix to use as a bed for the new seedlings
  2. a huge stock pot I found in the trash to use as a mixing vessel
  3. a 6" /15 cm shovel
  4. a supply of water
I dumped the starting mix into the stock pot.

added water to damped the starting mix

enough water that when the mix was compressed, it retained the shape of my hand.

The next step was to stake the garden.  I brought out a bucket of stakes I used last year to create the 1' x 1' /30cm x 30 cm grid within the 4' x 4' /120 cm x 120 cm plot,
a heavy hammer, in this case a ball peen, and twine.

I beat the first stake into the corner of the plot and extended a tape measure to 4' /120 cm and placed four more stakes along the tape measure at each 1' /30 cm increment.

When driving stakes it is important to hold the stake far from the end, so as not to strike your hand rather than the stake.  Another tip is not to hold the stake with an iron grip, so that if you do miss the stake and hit your hand it won't do as much damage or alarm the neighbors with all the yelling and swearing.  Wearing a glove also has the advantage of keeping the blood and broken bones together in a neat package until you arrive at the emergency room.

Once the stakes were set on the first side of the plot, I repeated the same process on an adjacent side.

Again on the third side.

And finally the fourth side.

It was time to begin stringing the stakes.  I tied the end of the string onto the stake with a clove hitch.

Then finish it off with a half hitch to keep the string from untying.

I went around the stakes until the string crated a grid of 1' / 30 cm squares.  There by getting its name "Square Foot Garden"

Each square was ready to plant.  Well almost.  I smoothed the surface of each square, removing any large objects from the surface.  In this case, I removed some of those roots I said didn't need to be removed from the soil when I mixed in the organic matter.  I also removed all large leaves from the surface.  They would smother the tiny seedlings.

I then formed three trenches and placed starting mix in each trench, tamping down the damp mix in each trench.

I tried carefully to remove each seedling from the paper towel in which it was entwined.  Some seedlings didn't make it and broke.  Those seedlings that were successfully freed from the towel were placed in the trenches leaving approximately 1" /25 mm between seedling.

I then covered the seedlings with starting mix and lightly tamped the mix atop the seedlings.  It wasn't necessary to have the leaves of the seedlings above the mix surface, they would find their way to the surface on their own.

I continued from square to square, flattening, smoothing, trenching, filling, tamping, planting, covering and tamping.

I photographed each square with the type seedling planted, for later reference.

One of the squares has half one seedling and half another.

These are the pea squares before I covered them.  I changed the direction of the trenches for no good reason except I liked the design.

Here is the plot fully planted, ready for water.  I watered by hose with the spray head set on shower.  I have a valve between the spray head and the hose.  I find this valve is a much better regulator than the squeeze handle of the spray head itself.  I watered until the plot was thoroughly moist.


My first planting of my square foot garden for 2012 was complete.
