Commerical growers question about the Mittleider method
A. 1) For commercial production 4'-wide boxes are probably the best and most productive. You can plant 2 rows of the climbing or tall plants in them and 4 rows of other large plants. You can even plant more than four rows of small things like radishes, carrots, leaf lettuce, etc. With most plants - climbing or large vegetables - you should plant at the edges and 12" in, leaving a 2' open area in the center of the bed. This is essential for adequate light to get to all plants as they grow and mature. 2) Fertilizer should be applied at the rate of 1 ounce per running foot of row for Pre-PLant Mix, and 1/2 ounce per running foot of row for Weekly Feed. Both are applied before planting, and mixed with the soil. 3) This should be done for EVERY vegetable and fruit you grow. Application of Weekly Feed should be once every week, until 3 weeks before harvest, for single-crop varieties. It should be applied until 8 weeks before the end of harvest for ever-bearing crops. It should be placed 4" from the plant stems, down the length of the row, and the watering will - over the week - take it into the soil at the root zone of the plants. 4) Everything can be grown successfully in either soil or Grow-Boxes. If your soil is particularly bad you may choose to grow in boxes. This will often minimize problems with bugs and diseases, although those can migrate into the soil-less mixture over time, requiring that it be replaced after a few years, unless you cover your ground with something like roofing material first. 5) Planting can be closer than traditional methods. It also depends on the size and variety. We have planted sweet potatoes closer than 12" and as far apart as 14", and a 4"-wide bed will accommodate 4 rows. An 18" bed will allow 2 rows of all plants except climbing plants, which should have only one row. 6 & 7) I recommend you use the Pre-Plant and Weekly Feed, without any changes, on every plant you grow. This includes trees, bushes, flowers, and even grass (and sugar cane). The amounts and frequency will vary greatly, depending on the size and growing habits. Fertilizing trees should be done twice each year - once at budding time, and again when the fruit is forming. Amounts to use depend on the size of the tree. Look in the FAQ section of the website under Trees to find an article about feeding trees. It's true that some plants and trees use a little more of one element than another. The Mittleider natural mineral nutrients are complete, balanced formulas that have enough of every required element that you will seldom see a deficiency. Make sure you have the Mittleider Garden Doctor set on hand. Then, if you do see a deficiency developing you can quickly identify it and apply the correct dosage of the needed mineral. This is far better than trying to develop a separate fertilizer for each type of crop, for smaller growers. When you get to the point where you are growing many acres of a single crop, then you can get more sophisticated and custom mix your fertilizers for that crop.
