March Coupons from Viragrow for Vegetable Production!

Many people responded to discount coupons on compost materials from Viragrow in February. I proposed some discounts for March as well and they agreed! So here they are for the organic and conventional gardener. I tried to propose what you might need in the next few months in a vegetable garden. On the right side are conventional fertilizer products. On the left side are for those who prefer organic products. Remember, fertilizers DO NOT substitute for soil improvement with organic materials like compost! If there is a product I am missing, please let me know.

Blood meal is high in nitrogen so it is used to promote leafy growth and stems. So is the conventional fertilizer, ammonium sulfate. Flowering plants like tomatoes, peppers, eggplant, squash, etc. need to get some size on them before flowering so you would add high nitrogen fertilizer after planting (seed or transplants) to give them size. Bigger, leafy plants produce more fruit so get some size on them quickly and then get them to set. I usually "sidedress" nitrogen fertilizers once a month. This is dropping small amounts of high nitrogen fertilizers along a row, 6 inches from the plants or alongside each plant if they are spaced far apart. Since this blood meal is 12% nitrogen you will use about twice as much as you would the ammonium sulfate (21% nitrogen)

Bone meal is high in phosphorus (15% on the label which actually converts to about 30% phosphorus) and promotes root, flower and fruit growth. Ammonium phosphate, a conventional fertilizer, is also high in phosphorus (20% on the label which converts to about 40% phosphorus). Phosphorus does not move in most soils very well, unlike nitrogen and potassium, so you should mix this into the soil when you are preparing your garden. OR mix it with the soil surrounding the roots of transplants or seed. When planting transplants like tomatoes I would usually dig a hole for the transplants, reserve the soil, mix in a small amount of phosphorus supplement with this soil and use this soil to backfill around the roots of the transplants.

Seaweed extract is a complete fertilizer (containing all three major nutrients) as well as the conventional Super Bloomer. Notice that the percents of nutrients in the seaweed extract is much lower than the conventional fertilizer, Super Bloomer. Both make fertilizers that you can spray on to plant foliage. This is a way to "feed" your plants through the growing season with a complete fertilizer. "Feeding" plants is necessary in intensive gardening techniques where you are "feeding" plants in small, intensively planted gardens. Note that the seaweed extract has much smaller percentages of nutrients than Super Bloomer so much less of the conventional product is needed. However, seaweed extract has quite a few more minor nutrients than Super Bloomer and has them in naturally, chelated forms.
