I am fortunate when it comes to broccoli. Not only do I live in an area where I can grow broccoli fairly easily (broccoli grows in most zones), but both my children love eating broccoli. So as you can imagine, having my kids involved in planting, cultivating and harvesting broccoli is an easy task.
Broccoli uses a lot of nitrogen from your soil, so in order to make sure
the area where you plant your broccoli will be adequate, be sure to add
plenty of shredded leaves and grass clippings in the previous fall.
That means right now!
I like to start my broccoli from seeds indoors about three to four weeks
prior to the final frost in my area. You can always locate your frost
zone from the new and enhanced USDA Plant Hardiness Zone Map
on the USDA website. I use a homemade potting soil to start my
broccoli seeds in. It is a combination of equal parts compost and peat
and I mix in just a little perlite. I use to add in equal parts of all
three, but I found the perlite in such a large quantity is really not
Once the fear of frost is gone, I will transplant my broccoli plants to
their permanent location in my garden where I know they can get full
sun, although broccoli will still do well in partial shade. I space out
my broccoli plants about sixteen to eighteen inches. Broccoli plants
can get fairly large. In a square foot garden, you might be able to get
away with one square per broccoli plant, but that may be a bit tight.
Fertilize your broccoli plants every couple of weeks with a quality
organic fertilizer. I tend not to use synthetic fertilizers. The
choice is obviously yours. Fish emulsion is an excellent source of
fertilizer for your broccoli plants.
You will know it is time to harvest the large head of broccoli, when it
is dark green and firm. If you start seeing yellow in the buds, your
broccoli is starting to over ripen. You will want to harvest your
broccoli as soon as possible.
Just because you harvested the entire head of broccoli does not mean the
broccoli plant is done. Throughout the course of the remainder of the
season (at least a few more weeks in most areas), your broccoli plant
will grow small shoots of broccoli which can be harvested and thrown
into a salad for a nice fresh treat.
