Planting Broccoli + Cauliflower And How To Build Garden Containers

I’m not one to pick favorites in the garden but I will say my heart skips a bit faster when I see a full head of broccoli growing.  Last year we had pretty great success with our broccoli with sizes that I couldn’t even dream of, so this year I’m hoping for the same.  I know, I’m putting pressure on the broccoli, but I’m very supportive too so it works out. 

Last year we had many heads of broccoli, much of when I froze to use in recipes all summer long.   There was a week straight where we were cutting off multiple big heads of broccoli every single day.
Harvested the first broccoli of the year, biggest broccoli we've ever grown! Yay!!
Broccoli – last year.

Cauliflower though, that’s another story.  We’ve never had great success with cauliflower.  In the first few years we grew cauliflower about the size of half dollars.  Then last year, we were growing decent size ones (although still on the smaller size) and both Hurricane Sandy and then a aphid apocalypse hit – both not being kind to the cauliflower.  So this year, if I can be ever so bold I’m hoping for not only big broccoli again, but I’m hoping for some big cauliflower heads too! I’d love to snack on them,  steam them, eat them raw, melt cheese on top, hug them and whisper sweet nothings.  Please cauliflower, please!

Cauliflower – last year.

So a few weeks ago, on April 6 we transplanted the broccoli and cauliflower seedlings to the roof where they have been living under a green house since.  Doing the containers for these plants really feels like the start of the gardening season because it really is about the garden basics of building the containers, turning soil, planting.  Once the containers are built then they are recycled throughout the rest of the year with other plants depending on the season.  It’s a process that leaves us a bit tired and needing a nap afterwards, but we cant nap because we’re too excited.  

 The rest of this post is very picture heavy with how we prepare the containers, and some progress shots up to yesterday!

The plants don’t get transplanted until the greenhouse is built as they will live under this for a few weeks.  It’s been up and down in the weather here with some nights going below freezing, so it’s very important they have a warm home.   In early March we endured the chilly weather and put the green house up and replaced the plastic.

Then all the containers get removed from under the tarps where they sat all winter.  In the last few years we have collected many containers!  Hint: If you’re in a city, look for them outside on the curb on trash nights, it can save you lots of money!  Just make sure they aren’t cracked.

blogWP_20130328_044
Get your muscles ready because this is the hard part.  All the containers need to be emptied so you can flip the potting mix, give it nutrients and set up the pipes.  All of our containers are sub-irrigated so they get watered through a feed tube which them waters the plants from the bottom.  We use 2 types of pipes depending on what we have available, they both work equally well.  In the box above we use corrugated piping.

blogWP_20130328_048
Or you can use PVC piping cut up.  Just make sure you always leave a hole for the watering feed tube.

blogWP_20130328_045
When starting the containers, add a little bit of potting mix at the bottom and add water.  Pat this soil down so it becomes firm with the piping.  This is starting the wicking process which will continue to water your plants throughout the season.

blogWP_20130328_038
Keeping add potting mix to all the containers.  Reminder, if you are using containers, use potting mix!  Potting mix is officially one of my best friends.

blogWP_20130328_043
Add Perlite to all your containers and mix it around with the potting mix.  Perlite allows drainage and access for the water to move around in.  

blogWP_20130328_040
Keeping doing this until all your boxes are filled.

blogWP_20130328_051
Then give them all one last sprinkle of water on top.  You want that potting mix wet (not soaked though).

blogWP_20130328_046
Now you want to give your containers some food for those vegetables to eat later on.  We like this plant food, it’s worked well for us.

blogWP_20130328_047
Just dig into the edges of the box with your gloved hand, sprinkle plant food and then cover it up.  Your plants will love you for this!

blogWP_20130328_050
Now it’s plastic time.  What? Ok, so you built these amazing containers! But you want to keep the moisture IN the containers.  And let me tell you if you are growing on a roof and it’s getting beamed by the sun, you are going to need all the moisture you can get because everything will dry out very quickly.  So we cover every single container up with plastic.  

blogWP_20130328_054
Rip a hole in the plastic for the feed tube, then tape the plastic on.   Make sure you use tape that can endure all weather conditions.

blogWP_20130328_053
Do this for all the containers.  If you have 2 people, that’s best case scenario as one person can hold the plastic while the other one tapes it.  At least once Matthew accidentally tapes my hand to a container.  

blogWP_20130328_059
One more thing before you add your plants – first water your containers.  You want to drill a hole into every single box – this hole should reside at the top of the inside of the pipes.  When the containers are watered, these pipes will fill up with water to the top, touch your soil and continue the wicking process.When water comes out, the plant has enough water.  This way you always know the plant isn’t under or over watered. Now fill up every single box until water comes out of the water drainage hole.  

blogWP_20130328_068
 This box was watered, it’s coming out, so it has enough water.  Note: Move shoe out of the way so foot does not get soaked – ooops.

Now finally – we can transplant the broccoli and cauliflower!

blogWP_20130328_065
These are the broccoli and cauliflower seedlings.  The seeds were planted January 12 and this picture was taken April 6 so they were growing inside for almost 3 months.  There are 24 plants in all – 12 broccoli, 12 cauliflower.

blogWP_20130328_063
Can we talk about how big their roots became in those 3 months?

blogWP_20130328_070
Each container gets 4 plants so we evenly distribute the broccoli to all grow together and the cauliflower to grow together.

blogWP_20130328_075
6 containers x 4 plants = 24 in all.

blogWP_20130328_073
I’m always in awe of the beauty of the seedlings.

blogWP_20130328_072
I love them so much.

blogWP_20130328_079
Then one by one, we make holes in the plastic and the seedling gets transplanted inside.  Pat it down, make it a nice home in that potting mix.

blogWP_20130328_076
I gave this one a nice little pat and told it that I loved it very  much.

blogWP_20130328_078
Every single one was planted.  But it was still March so they needed protection.  The greenhouse goes on…

blogWP_20130328_083
Tip:  It gets cold at night so if you fill up old bottles with water – the water heats up the in the green house, causing the temperature to rise in the greenhouse.  If you ever open your greenhouse during the afternoon and feel one of these bottles you’ll be surprised by how warm it is.  

And then you cover them up, tuck them in and wish them well.  Now the exciting part that causes me high anxiety.. the waiting!
But what I love even more, tracking their progress!

A few days later we see they have transitioned nicely to their new containers.
These were taken April 8 – 2 days after transplanting.

Then a week after transplanting on April 13, we are noticing them grow in size..

Then it really starts to get wild/exciting/makes me want to dance. 
This was taken yesterday – April 22, 16 days after transplanting.
~SWOOOOOOOONS~
