Grow a School Garden – Feb/Mar 2018
Monthly blog by Chris Collins on How to Create and Grow a School Garden
Spring is nearly here
It is this time of year that suddenly a day will come when finally after a long winter, everybody will feel the warmth of the sun on their face again. It’s such a welcome feeling and also very exciting time for our outdoor spaces.
This is the time to get busy in the garden, particularly for producing plants. Seed sowing is the one thing that can really get children hooked on growing plants . Watching a seed come to life and grow into a plant is a wonder that never gets tiring.
Tips for seed germination
So here are some ideas for getting your seed going.
Firstly if there is a budget, I really recommend investing in a couple of propagators . These are basically mini greenhouses that can be kept in the classroom and used to start all those tender crops that will need protection from the spring cold.
Tomatoes, Broad Beans, Courgettes, Squash and Pumpkins will all germinate well in a propagator, which can then be grown on indoors until its time to plant out.
Starting these plants like this means that you will be planting out strong healthy plants. It will extend your growing season, hopefully meaning you will get plenty of crops before the summer term ends.
History and science lessons with seeds
Growing seeds in the classroom like this also lends itself to the opportunity to studying how seeds work. They are truly incredible things, a couple of examples of this could be the Giant Redwood, the biggest living plant on Earth that has a seed that is a billionth the size of a fully grown tree . Or why are Poppies associated with Remembrance day. Its because Poppy seeds only germinate when they are exposed to light . The artillery fire unearthed Poppy seeds, some of which may have been underground for over a hundred years and then they proceeded to grow and flower. This example can also be used to teach some of the history of the first world war.
Raking and treading soil
Seeds, however also give us the chance to get outside and get our Carrots and Broad Beans growing. The soil will be all nicely dug from the winter gardening, now we can rake and tread it.
This entails using the rake to create a soil as level as possible . Use it to take out any lumps or dips. Treading means to use the back of your heels to firm down the whole area. It means a funny walk across the soil but it takes out all the air pockets and allows smooth capillary action enabling water movement in the soil.
Once you’ve done this, Carrots can be sown in drills. Put down a line of string across your plot, make a small trench along the line (use a piece of bamboo) and sow your seeds (check the packet for spacing tips), cover over, water and label.
A good tip is to use a watering can with a rose head, turn the rose so its facing upward, this will create a fine water spray when poured and thus prevents you washing out and displacing those carefully sown seeds. Using a line (drill) to sow seeds like this means when they grow into seedlings you will know what they are and distinguish them from any weeds growing at the same time in the surrounding soil.
Veg writing project idea
A couple of projects for early spring could be Veg writing. How about sowing some Salad leaves with your name or the school name? Mark out the name with sand and make a small trench in the sand and sow in Rocket or Green salad leaves. Then using drills surrounding the sown Rocket, sow red leaved Salad. When it all starts to grow you will see your school name. Clip with scissors from time to time and use the clipped salad leaves in sandwiches.
Window ledge herb garden
On the topic of edible plants, a small herb garden can be made and sit outside the classroom on a window ledge.
You can get yourself a pot or is there something we can recycle?
You can use many things for a pot just remember that it will need drainage, so make sure you can put holes in the bottom of it. Herbs don’t like wet feet, so mix peat-free compost with some gravel or sand. Maybe put some gravel in the bottom of the pot too.
If you are putting it on a window sill make sure it fits before adding the compost.
Then start to collect and plant your herbs. Small herbs like Parsley and Coriander can be grown from seed. Larger herbs , like Lavender and Rosemary can be bought, quite cheaply from the garden centre and why not see if anyone has Oregano or Lemon Balm as these can easily be divided up – maybe someone’s Grandma has some in her garden somewhere!
