Your question: Hi Moreless and others, hope you are well.
I haven't posted in a long time, however I read every post everyday and am still loving it and trying to learn all the time.
I am going to start a sq.ft. garden this weekend,I have 4 boxes made and my soil ingredients.
I plan no making @ 32 cubic ft. of soil as follows:
1/3 peat moss
1/3 medium grade vermiculite
Question: What Alkaline Minerals can you find in peat moss and vermiculite?
What about the compost? What kind of compost is it? What is the Compost made from?
Where are you going to get the needed Alkaline Minerals from? End.
I am planning on placing the boxes in full sun?
I live in So. Calif. where it gets faily warm, is full sun ok?
Should I add anything else to the soil like kelp, bsm etc ?
Answer: I do not consider the above to be Soil ! End.
My boxes are 2x6 , meaning the beds are 5.5 in. deep,and there is no mention of mulching with this method.
Moreless I would really appreciate any advice or insight you could give me in starting a sq. ft. vegetable garden.
Thanks for everything you do, you are doing a great job, keep it up.
Suggestions: The problem with this kind of gardening set up may be that one is not providing for the Soil Life something to eat as Compost has been pre-digested already and the other two ingredients may not supply anything except a media to hold the roots and help aerate?
If one is to put dirt into boxes to grow food, then it would be best to find dirt that has had green grass or plants worked into the dirt the prior year along with needed Minerals to prepare it for the boxes?
This action allows the Soil Life to convert the green plants into Live organic Matter better balanced to the needs of Top Quality plants needing to be grown !
Many times Compost may have animal manures added or as a part of them and may contain too much Nitrogen to the needed Minerals, thus producing Lush Green plants that the Bugs like to eat and that may be of Poor Quality !
So what is one to do who does not have this kind of dirt to add to a box?
Plan ahead for next year and make do the best one can this year !
In this case I would take what you have and add
5# Granite dust
5# Fine Ground Limestone(Calicitic, not Hydrated)
Mix it well with the other ingredients and mix in 5 gallon water 1 Quart of BSM with 1 cup of Fish emulsion and water this into the mix and let set one week and then plant !
It may be Important to let it sit and let the ingredients react before planting?
Then find some grass leaves or other like mulch to keep a mulch on top of this soil to feed the soil Life.
One could use alfalfa meal as Mulch if one was growing Greens and maybe for other plants as long as the compost did not have lots of Nitrogen !
Smile Tis your choice.
