Six laws of plant growth

Six laws of plant growth

In the Mittleider gardening method Dr. Jacob Mittleider defined the six laws of plant growth.  If the gardener will observe these 6 laws their garden will do well.

Law 1 – Light

Direct sunlight is best for your garden.  All day sunlight is best but you will need 6-8 hours at a minimum.  Avoid shade from objects such as buildings and trees.  Shade from other plants should be avoided when possible.

Law 2 – Temperature

Seedling production and seed germination are best in a narrow temperature range.  Seed germination requires a soil temperature of 70-85 degrees.   Seedlings require soil and air temperatures to range from 65 to 85 degrees.  Outdoor plants need air temperatures between 60 and 90 degrees.

In temperatures above 90 degrees it may become necessary to provide partial shade.  For colder temperatures it will be necessary to provide supplemental heat.

Law 3 – Air

Third in the six laws of plant growth is air.  Plants pull three different nutrients from the air to create carbohydrates.  Those nutrients are oxygen, carbon and hydrogen.  Plants take in air through their roots so it is very important to have proper soil drainage.

Law 4 – Water

A plant is comprised of 80 percent water. Nutrients are carried down through the soil to the roots by water.  Water must be available at the roots for them to take up nutrients.  During hot weather the plant will try and control its temperature through transpiration with the water.  If the plant is wilting it is dying.

Law 5 – Nutrition

This law is the one that most gardeners fail to fully provide  for their garden.  Your garden needs 16 nutrients to produce healthy plants.  For healthy growth of your garden the plants require a balanced nutrition at all stages of growth.

Plants take in their nutrients in a water soluble form through their roots.  If your nutrients are not water soluble they will not be immediately available to the plant.

Three of those nutrients the plants take from the air, see Law 3 above.  The remaining 13 the Mittlieder gardener provides to the plants.  They are comprised of macro, secondary and micro nutrients.   Macro nutrients are NPK, also known as nitrogen, phosphorus and potassium.   The secondary elements your plants need are calcium, magnesium and sulfur.  The micro nutrients are zinc, manganese, molybdenum, copper, iron, boron and chlorine.

Law 6 – Competition

The sixth and final of the six laws of plant growth is competition.    Competition can come in several forms for the plants in your garden.  Disease, animals, out of control weeds, insects and even other plants in your garden can compete with your plants.  Learn to eliminate or control the competition while observing all of the six laws of plant growth and your garden will amaze you.

Changes to the in garden greenhouse

Recently we made changes to the in garden greenhouse.  Arguable some of these changes are improvements.  They were all minor additions that didn’t add much cost to the project.  Ideally these changes would have been made and implemented during the build.  If you are considering building this I’d highly suggest altering your build plans to include these changes.

During our time with the Mittleider in garden greenhouse I’ve changed a few things about it and added my own personalized touches to it.  I’ve outlined these things in this little video we shot today.

We built the in garden greenhouse from the instructions provided in the Mittleider Gardening Course book.  We don’t provide a supplemental heat source to it, but are able to increase our growing season by about 6 to 8 weeks.   It allows us to start planting hardy plants 3-4 weeks before our average last frost of the year.

After the first frost of the year it also allows us to continue growing and protecting our vegetables by simply closing it up and protecting the plants from the cold.  On a sunny day we can easily see temperatures inside the  greenhouse rise 30 degrees above the outside temperatures.
