soil prep suggestions for old schooler?

18 years ago

Hi folks,

Great forum here! And apologies in advance for this long note.

I have done SFG in the past based on the original book. But I gather that since my last time (1999?) a new version of the book has come out. I'm sure there are improvements in the new version (I guess Mel's Mix?), but I was always happy with my results using the old one.

I'm recently divorced and just starting to pick up some of my old hobbies, one of them being gardening. So, without having consulted this forum first ( :-/ ) I just prepared a new plot (small, 4'x3', more than enough for me) for planting. This area is mostly sand, so last spring I incorporated large amounts of compost and synthetic fertilizer down to maybe 12 inches and just let it stew.

Digging it over last week it looked much better, but still mostly sandy. So I removed the top eight inches or so and layed down two inches of "mostly complete" homemade compost. By "mostly complete" I mean that there are still lots of small chunks of shredded salt hay that have not completely decomposed yet, but the rest of the mixture is mostly black and earthy.

On top of that I added 2 inches of the soil I had removed, and worked it in.

Then I added another 2 inches of that "mostly complete" compost, 3/4 cup of Jonathan Green's "Mir-a-cal" lime substitute (soil test indicated too much acidity) a bunch of vermiculite (I don't know how much exactly, it was whatever I had leftover from the last time I did this, but it did cover the entire surface well before I worked it in) and brought it up to grade with more soil, and worked it all in with a rake. Then I soaked it.

When it settles more, or at least by planting time, I plan to add more compost and soil 50/50, to bring it up level.

Soil test indicates good fertility, so I did not add any fertilizer, though I will probably add some fast release nitrogen when I plant.

My question is this: given this background, what else would you do to improve the soil? I anticipate planting (mostly transplants) in three weeks, so I have some time, but not much...

Thank you very much!

Paul

    Hi Paul,

    Your soil sounds pretty enviable already! Does it drain ok, while still holding sufficient moisture? What zone are you and what are your summers like (hot and dry like mine, or generally moderate like New England?)

    Thanks Kris! Hot and damp, I'm along the shoreline, probably zone 6b, though it seems to depend on what map I am looking at....

    Hot and damp, I'm along the shoreline, probably zone 6b,

    I used to garden in Niantic, right at the beach - very sandy, and slow to warm up in the summer, although the growing season lasted much later into the fall than it did inland. The early summer is still good for cool-weather crops but if you are desperate for tomatoes or squash it can be hard to take.

    The big difference in the new book is that it recommends gardening up instead of down - that is, building raised beds in boxes and filling them with new material instead of digging and improving the soil. This is what I'm doing (at a new home in the Finger Lakes region of NY) but I can't see any reason to switch to it if you know and can work with the original way.

    Hi okmoreh, Niantic is just up 95 from me, I am in Clinton. That sea breeze sure is good at cooling things off in the summer, but you're right, it seems to extend the early spring. No tomatoes until 5/15 for me! Thanks for your explanation of the new book, maybe I'll try that someday, but not this year.

    Other than peat moss you've got Mel's Mix pretty much down pat. Yeah you've got sand, but if it works for you. Use it. My soil was so hard packed from years of neglect and sun baking that I just built over it with Mel's Mix. Best of luck and enjoy your garden!

    That sounds very good. Several of my beds are just several inches of compost over existing sand that has mixed as the years have gone with the help of the worms and the disturbance of pulling up spent plants. With that much compost, I'd skip adding fertilizer at planting, perhaps save some to supplement the more draining plants later in the growing season (e.g. tomatoes)

    Thank you folks. Yes, I have a lot of sand. I replaced the septic system here, and when they dug their test pit I learned that most of my yard is one foot of good soil on top of at least ten feet of sand. Apparently the whole neighborhood was a tomato farm for many years before being developed in the 1950s.

    But this particular plot is right next to the house, and since it is (was) mostly sand all the way to the top I suspect this is just the backfill from when they finished the foundation. So I imagine I'll have zero problem with drainage, but may have problems with retention. If I do I think I'll just water a little more heavily this year and add some peat in the fall and work it in, thank you for that.

    Also thank you for the advice on holding off on more fertilizer just yet. I think I'll wait at least a month to see how things are growing.

    Thanks again!
    Paul
