We have been enjoying our indoor herb and greens gardens. The boys have been interested in what happens under the dirt as everything grows. So, we started a project where the boys are growing wheatgrass in a canning jar!
It is very easy to do, and it is cool because each part of the growth process is visible through the glass - from the sprouting wheat berries to the burrowing roots to the shooting bright green blades.
All you need is a bit of sand, some potting soil, canning jars, wheat berries and a spray bottle with water. Start off soaking the whole wheat berries in room temp water for 8-12 hours - drain/change the water about half way through. You can find whole wheat berries usually in the bulk bin at your local grocery store or coop. Organic is best since it is not treated with anything and will sprout healthily! You can use any glass jar - I use canning jars because it is what I have at hand. We used pint jars.
First spoon about an inch of sand in the bottom. Follow that by spooning about 1-2" of potting soil on top of the sand. The sand is to just help keep it from getting too waterlogged (my boys love to squirt the water). Top it off with a dense layer of soaked wheat berries. We used about 1-2 Tablespoons of wheat per jar. Don't put too thick of a layer of wheat or the bottom ones may get moldy.
Water lightly and then cover (loosely) with saran wrap and place on your kitchen counter in a dark or shady spot. Spritz well with a spray bottle of water morning and night. After the first day or so the berries should be sprouting - remove the plastic wrap. Keep in a (not too hot) light place once they start sprouting - not direct sun though. A bright windowsill or a table near a window is fine.
Continue spritzing with water twice a day. Once the grass is growing, rinse out every day - just fill the jar with cool water, then use a finger to gently hold everything in as you pour it back out to drain. This just keeps the lower wheat berries from getting moldy and rehydrates the soil if it is a bit dry.
You can feed the grass to your pet, juice it in a wheat grass juicer and add to smoothies, or, of course, keep it as a cool green burst of life on your table.
wheat grass smell after he gave it a trim. :)
It is really simple to do, happens quickly, and does look cool all lined up on the table - especially when the temps are going to be below zero all week. A nice living green centerpiece!
