OK, I guess I am in the right path.
Thank you all! I know it is not easy work, specially in the beginning, but it should improve overtime. But I don't want to break the bank to get there. I did work out my formula and after doing the math, I think I can get the fertilizer price in 1/2. But I have to come up the cash now to get all the fertilizers.... I will see maybe I can try next year.
I can say first 2 years (2011 - 2012), we have to buy veggies during the summer months, last 2 years, we were able to eat what we have from our garden from June - Oct without buying veggies, and give some to our friends and neighbors. This year, we want to improve what we harvest like size and taste of the harvest because we ran out space to expand!
A bit more information on what we grow so you might know why we are breaking the bank buying fertilizers. My wife (as you can see, it's my wife, not me ) actually planted so much veggies and fruits, I think she is addicted to planting and starting seeds, she wants to grow everything she can...
What we have in our garden (our neighbor call us farmers ),
Sweat pea, radish, bean, EDITED - PLEASE REPORT THIS POST, tomato, lettuce, eggplant, hot pepper, pumpkin, squash, bitter melon, okra, Chinese okra, winter melon, water melon (my idea), 58 asparagus crown (my idea, planted in 2014, got 2 lbs from it in 2015) and some plants I don't even know what they are called ......
Fruits tree - they are all young trees when we got them
Strawberries planted in 2013 - have good harvest
blue berry planted in 2011 - have good harvest
black berry planted in 2012 - have good harvest
mulberry - have good harvest
fig planted in 2012 - figs keeps dying back during winter time, so it gives some fruits, not much
cherry planted in 2013 - 8 cherries from 1 tree
apple planted in 2012 - 8 apples from 2 trees
pear planted in 2013 - have good harvest
grape planted in 2012 - lots of fruits, but the wasp ate them all....
But I can tell you, if it wasn't for my crazy wife , I wouldn't know how good a vine ripe tomato tasted.
Too much information.
