how to be a smart gardener

Our charity project is coming along

These are photos from an ‘Energy garden’ project we are doing on a London Overground station.  The intention is to have vegetables, herbs and flowers growing on the platform, with rainwater harvesting, composting, and recycling.  So the vegetables and flowers have been planted and are doing well- thanks to the station staff who look after them.  A mural and slate plaque are planned for later this summer.

This work is being done as part of the environmental design charity I started, Charushila.  For more information see www.charushila.org

This video introduces the Energy Garden concept which is a partnership between London Overground, Groundwork Trust, Repowering London and local organisations like ours-

Coconut husk compost

I have just started using coconut husk compost for my spring/summer planting.  First of all, I have to comment on how easy it was to transport and use.  I didn’t have to lug a heavy bag of compost on the bus- the compost comes a brick sized light block.  I took it out of the paper wrapping (which was recycled unlike the usual compost which comes in a plastic bag and it is difficult to find places that recycle them), then put the entire brick into a bucket on a day when I knew it was going to rain heavily.

So when the bucket was full of water, the coconut compost expanded to fill the bucket (one block makes 9 litres of compost). I could then use it to fill my baby bath tub planter which I found abandoned.

I had used up the winter offerings of dried shrubs and leaves as a composting material, on which I lay the coconut husk compost. I spread some seeds on the compost and then spread a thin layer of the coconut husk on that. The coconut husk compost is easy to work with, unlike the conventional compost.  My seeds are now sprouting and I will keep you updated on how the plants do.

Making a terrarium

IMG_0572.JPG

I travel quite frequently for work, so while I like to see greenery indoors, I found that I can’t really take time over indoor plants.  From books to plant feeds and self-watering systems, and once, even leaf shining wipes (embarrassing!), I have tried many ways to look after these plants.  Inevitably these have been a waste of time and money.  I have been responsible for many shriveled and dead plants.  So now I have made a terrarium.

While I looked at many Youtube videos and web based advice before starting out, I was also keep to make it out of what I had at home and not buy more stuff.  I also took inspiration from the Princess of Wales greenhouse at Kew Gardens, London.  I learnt that there were some key ingredients for a terrarium-

  1. An inert base made of charcoal, especially if there were plants needing frequent watering.  The charcoal helped to absorb odours, keep the terrarium free of fungal or insect infestations, like it does in aquariums.
  2. Moss- which helped to regulate moisture in the air, absorbing the excess
  3. Main plants that you want to use inside and any ‘decorations’

Charcoal is useful if you are going for a closed self sustaining system but as I was using cactus and succulents, my terrarium needed to be open and so I didn’t need the charcoal.  So I made the base of used match sticks, found the moss in the garden and I already had the pasta jar which I cleaned before use.  I reused the compost that came with the succulents and cactus to which I added some sand.  Believe it or not, the aloe plant came as a decoration from a plate of rice ordered in a restaurant!  I needed to have a vision of what I wanted the terrarium to look like before starting.  If you like, you can draw a rough sketch before inserting anything inside as it can be very fiddly to take things in and out and also this risks damaging the delicate plants.  You can use chopsticks, or tweezers or any kind of grabbing instrument to place the plants.

I first laid out the matchstick base, then put in the soil over which I laid the moss. I kept space in between these where I wanted to place the plants.  These plants do not need depths for soil- they are happy with shallow soils as their roots don’t go very far.  What you need to be careful with is the amount of water you use as these plants need good drainage.  After I inserted everything including the ornaments, I sprayed the inside generously.  Then I forgot about it!  It has been one month now and the cactus has sprouted a little baby and the succulents, aloe and the moss are doing fine. I spray water every 3 weeks and that seems to keep it fine.  Too much water and everything will rot.  My next project will be to make a terrarium for orchids.

Buildings, beauty and plants

Even the most ugly buildings get transformed by flowers.  I have been photographing beautiful flowers on buildings.  As John Ruskin realised during the Industrial Revolution ‘that the quest to make a more beautiful world is inseparable from the need to remake it politically, economically and socially’. Tsunesaburo Makiguchi believed that beauty, benefit and goodness provided the basis for a creative society.

I am currently working on a project that is bringing beauty in the form of plants and flowers, sustainability in the form of rainwater recycling and solar panels and benefit in form of public seating in a rather plain London overground station.  Here are some photos that I took for inspiration ranging from pubs, houses and stations

Reuse, recycle

IMG_2429.jpg

At the end of events, I always ask to take away flowers that might be placed on our table.  The reason is that such decorations are always almost thrown away.  What a waste!  For example, Anthuriums are one of the most popular tropical flowers with a long vase life of about six weeks and even more depending on the variety and season.  The staff are also happy to see the flowers go to a good home and it saves them clearing away.

Here you can see flowers and foliage from a corporate event, mixed with my own Christmas holly (yes, they are still going strong after more than two months!) and ‘Ruscus’ leaves from my Buddhist altar.  When these wither, then I will compost them.

Natures does not make waste

I used to wrap sweetcorn in aluminium foil and bake it- along with countless other times of using the aluminium foil for other things.   I learnt a more eco-friendly way to bake sweet corn from my vegetable delivery company last week.  And it is very simple too.  Just soak the sweet corn in water for 30 minutes without taking off the outer husk- it also keeps in fresher and sweeter for longer.

Then without taking off the husks, bake it for about 25-30 minutes in oven 180 degrees.  Take it out but do not remove the husks until the last minute- they will keep warm.  Then serve with lashings of butter and a little salt if you like, delicious!  You can also barbecue the sweetcorn in this way, instead of using the oven.

I can reuse the husks to cover other stuff instead of using foil and they cover tricky shapes like ovals and circles as they stretch. Foil is of course, recyclable infinitely but the raw production of it is very energy intensive. Foil can be reused but most people throw it away after one use.  Used husks below are very easy to use- and after the second use, I have now put them for composting- Nature does not make waste!

I found the following information about aluminium foil. http://www.green24.com/lifestyle/foil.php

Up to six tonnes of bauxite ore (the raw material for aluminium) is needed to produce one tonne of aluminium metal. Lot of of fossil fuels are used to mine, transport, and refine the ore (embodied energy). Foil in a landfill is said to last at least 400 years before breaking down. Burning aluminium foil with the waste from landfill sites (as many people don’t bother to re-use or recycle it) releases toxic metals and gases.  Health concerns have been raised about using aluminium cooking vessels so using foil should have similar concerns.  So why not use a totally biodegradable and natural material to bake or barbecue your sweetcorn?
