Cleaning Your Sprayer

When your sprayer becomes clogged with debris,
it is a simple matter to unclog the nozzle so that it will deliver what
you want and where you want it. Walter shows how to put your sprayer
back into working order and demonstrates how to clean residue from the
sprayer using either 2 oz. trisodium phosphate, 1/4 cup of ammonia, or
1 T of dish detergent per gallon of water.

Recipe for Changing Hydrangea Flower Color

French hydrangeas are famous for their ability
to have either pink or blue flowers. The bloom color depends on the
amount of aluminum available to the plant. And, the pH of the soil in
which the plant is growing determines how much aluminum a hydrangea can
absorb. Walter explains how to manipulate the soil pH using hydrated
lime and aluminum sulfate. A low pH soil yields blue flowers, while a
higher pH causes the hydrangea to produce pink blooms.

Why A Tree Falls


We can learn much about tree physiology when a
large tree falls. Walter uses a fallen tree to refute the common myth
that trees have long taproots. He also shows how "included bark"
eventually caused the failure of a 100-year-old oak.

Rocks in Pots

You'd have to have rocks in your head to put
stones in a clay pot after seeing Walter demonstrate why the rocks
actually harm plants rather than promoting good drainage. A better idea
is to support the pot on rocks placed in the saucer underneath.
