Why do I need to fertilize?

Fertilizers

Fertilizers are the essential mineral raw materials from which plants make food.

The fertilizers in soil can be compared with a checking account in a bank.

  • Every crop reduces the amount of soil fertilizer just as writing checks reduces the amount in a checking account.
  • If the amount of the check is more than the amount in the bank, the bank will not accept the check. Growing crops affect the soil in the same way. Planting a large crop when the supply of fertilizer is too low will result in crop failure.
  • Applying fertilizer to growing crops is just like making a deposit to a bank account. Plants are just like people (and pets and animals)—they require balanced nutrition.

Tip of the Day

It's Spring Planting Time! For those of you in the Northern hemisphere who have winters, March and early April are the time you need to be preparing your soil and planting the hardy vegetable crops such as radishes, peas, cabbage and broccoli.

The freeze/thaw cycles of winter have broken up and loosened most soils, so as soon as it's not muddy, go in and give everything a good weeding with the 2-way hoe (see Tools). Weeding thoroughly this early gives you the upper hand, and is very important.

If you grew a Mittleider garden last year, your beds will be easy to re-make. Just apply Pre-Plant and Weekly Feed to the bed area, then till them in, place strings on your stakes, and re-make the beds.

Be sure to re-check the level of each bed accurately, since they may have changed a little. Do not be satisfied with anything more than 1" fall in a 30'-long soil-bed. Good Gardening!
