Square foot garden soil mix….

There are some questions as to what the square foot gardener needs for success by way of soil.  As the book says, you’re not going to need or worry about your existing soil because you’re going to make your own.  By the time you’re done mixing it all in, you will have a perfect soil to plant just about anything you want.  No more worry about pH, soil structure, clay soil, loam soil, fertilizer, etc.  This picture shows what you’ll need to effectively grow your first SFG immediately.  First-peat moss.  This helps with keeping a nice, loose, and friable mix.  It also has some water retention properties.  Cost-about $7.  Second, coarse vermiculite.  This is mica rock that has been heated to a certain temperature until it explodes.  This is what helps hold water more than any other ingredient in your SFG.  You should always try to get the “course” variety instead of medium or fine vermiculite.  The finer you end up buying, the less effective it will be at holding water.  This is the most expensive component-about $25.  Third-a blended compost.  If you visit my gallery you will see the individual items that make up this great compost.  I think it’s the best commercially available compost available.  So, if you can’t find Garden and Bloome soil building compost, try to get something that approximates this.  Cost-$8.  This will be all you will need to fill one 4X4′ SFG at a depth of 6 inches.  If you want to go a foot deep then you will have to double this amount.  For the most part though, 6 inches will be all you’ll need for most things.  Do not cheat on making the soil.  This is a one time expense and you’ll end up regretting it later on if you’re getting the growing medium from the landfill or just buying horse/cow/chicken manure, etc.  It is not worth the few dollars you think you will be saving.  If you cheat on the soil and when you have limited success you can’t come back and tell all your friends “that square foot garden stuff doesn’t work.”  One of the worst things you can do is to fill your boxes with potting soil.  Why?  Potting soil is specially made to get new starts off quickly with a very small amount of fertilizer, peat moss, and some perlite.  It’s only made to be short term.  If you were to fill your beds with this your garden would be out of the necessary fertilizer for what you want to grow in about 4 weeks.  Be smart.  Stick with this triple combination and you can’t go wrong…

What should you be doing in your SFG now?…

That’s an easy one-planting! It’s the 3rd week of March and your soil should be loose, prepped from last fall and now ready to plant. Give it a quick turn with your trowel-one of only 3 tools you will need in the SFG system. Right now you should be planting all the cool weather crops. Things such as lettuce, swiss chard, radishes and spinach should be directly planted in the soil. There’s no need to start these items from seed indoors. If you’ve done it right and taken care of your soil you should have things coming up in 7-10 days. That’s if your weather is mild. If you are able to cover and protect your gardens, then you should still have things coming up in 7-10 days. That’s just how it is with us SFGers. Here you can see that I have thinned out my square so that it now holds 16 radishes. Now I just water, sit back and watch it grow. They’ll be ready in about 3 weeks. Just in time for my lettuce and spinach to be ready. When that happens I shouldn’t have to buy any produce or veggies from the store for at least 6, maybe even 7 months. How would you like to save that kind of money? Anybody can do it…join us at the several free lectures in town and then learn all of it at the workshops….

New spring spinach

This is a look at my newest spring spinach.  It’s about 2 weeks old right now and it’s looking good.  In the SFG fashion you will plant 9 seeds per square.  And that’s exactly what you’ll see in this square.  I’m trying to make a better effort this year at spreading things out a little longer than I usually have in the past.  I think I’m a lot like most of you-when it’s time to start planting you just want to plant everything all at once.  That’s the old single row garden mentality.  One of the keys to square foot gardening is to pace yourself.  If you plant 8 squares of lettuce at once and they all come up, what are you going to do with 32 heads of lettuce?  Now I’ll start to plant just a couple of squares at a time and separate my plantings by about 5 days.  Once again this is Space-our favorite variety from Johnny’s select seeds.  It’s very easy to grow, comes up quickly, and tastes good.  I also bought a new variety from Johnny’s this year that I’ve never tried before.  It’s call Tyee and it’s a variety of spinach that you can grow in the summer.  This will probably take the place of our New Zealand spinach which we normally grow in the summertime.  That’s OK by me-I think New Zealand is hard to grow and doesn’t taste that great.  It’s also not even a member of the spinach family but of the mustard family.  As I looked around the garden today I noticed that my sugar snaps have just started to break ground.  We’ve had some snow and cold weather so I’ve been covering up my beds.  Maybe I should have left the sugar snaps uncovered as they do well in cold.  But I’m sure it will all turn out well in the end.  None of the neighbors are able to start any gardens yet because their soil is too wet.  I will be planted for about a month before they get to theirs.  By the way-if you look very closely at this picture you can see a lady bug in the lower left hand section of the square(around 7 o’clock)….things are starting to look good…

Starting seeds in vermiculite….

I was reading on the SFGF official forum earlier today.  There was a post from someone who was disappointed when they tried to start their seeds early in vermiculite.  The comment was that only 50% of them actually came up.  Well, this is precisely why you want to start in vermiculite.  If you would have started those seeds in flats (or worse yet in the garden) and nothing came up you would’ve felt like you wasted a lot of time-and money.  And maybe even some of those plants that came up in the vermiculite to begin with wouldn’t have come up at all in the garden because of the weather.  But if you would have started them in vermiculite you end up only planting seeds that you know are good-because they have been sprouted in vermiculite.  This is a great trick to do when you have saved seeds from years past.  Over time these seeds lose more and more germination so you don’t really know which seeds are good and which aren’t.  By using vermiculite you only find out which are the good ones.  I’ve highlighted how to do this by pictures in the gallery.  This kind of information is what my “members only” page will consist of.  It’s going to show a lot of “how-to” and a lot of little tips and tricks of a successful square foot garden.  It’s not ready to go yet, but it will be shortly.  Hopefully….

My square foot garden in early March…

Many years ago when I was doing an internship with Mel he said to me: “what if you have a vegetable garden that is protected from wind, rain, snow and other bad weather?  All of a sudden, you have a different garden!”  And that’s the truth.  Today it’s been warm-about 60-but it’s been very windy.  I have now planted 2 complete boxes in the 2X16′ garden(16 squares.)  First, if I had a traditional garden I wouldn’t be able to plant yet.  The ground would still be frozen solid.  But then even if it were ready to go it would dry out quickly because of the windy conditions.  Because I cover my garden with plastic-making sure it’s vented so as to not get too hot-I can create an ideal growing environment for the items I’ve planted.  As others are attempting to get their gardens ready and getting out those tillers-do you notice the soil after their done?  It’s all in clumps!  That’s because the ground is not ready to be rototilled yet-it’s too early for those gardens.  Not so for the SFGer.  While your friendly neighbors are out there tilling away, we now have possible rain and snow in the forecast for this weekend.  That’s an easy thing for all SFGer to handle, but it’s not such an easy thing for a traditional row gardener.  So far I have now planted 8 squares of a variety of lettuce, 5 squares of spinach, 1 square of radishes, 1 square of carrots, and 1 square of walla-walla onions…..
