Growing 16 – Guerrilla Gardening

Seed Bombs
How they work – Seeds are wrapped in nutrient rich soil or clay. They get a head start for germination (especially good if planting into poor soil). Keeps them in a state of ready-to-go dormancy.

How to make them
Basically you will need to soak seeds that are ecologically suitable overnight. Then combine them with a soil or compost medium which can hold a ball shape. Shape them and dry them. They should store well for a year or so.

How to use seedbombs
When you are ready, simply toss or place them in the location where you want the seeds to grow. They can be planted in shallow soil or placed on the top. Water is needed to moisten the seedbombs and get things moving. Rain is good!

Seedbombs are a well-known tool of guerrilla gardeners but they can be useful even within your own private garden and plant pots.

Maintaining Herb Meadows
If you want your herb meadows to live in harmony with your neighbours then you will need to do a little maintenance now and then. The council will strip ivy (and roses) from tree trunks sometimes and they will strim back any plants that stray from your pit or geveltuin.

One spring and summer, I tended a lovely collection of miniature wild geraniums in the pavement cracks beside my first treepit. I thought they looked great and no one stepped on them. But they were removed by a street worker because they were outside of the treepit. Street workers have a job to do and they don’t have time to check on these things.  So re-home any interesting pavement crack plants, before they get the chop!

What are you doing to keep people, animals and litter off your herb meadows? Does it work? Is it possible to allow for different uses of your herb meadows (bikes, dogs & herbs)?  Have you tried adding signs? If so, what did they say and did they work?

To weed or not to weed?
We meet this issue often. Should we leave some ground covering, beneficial weeds to protect the soil and retain moisture or should we clear the plot completely so that only the wanted herbs are obvious? I experimented a little on my street, leaving Chickweed as ground cover and inter-planting with some great home grown herbs.

A neighbour thought the whole plot was weeds and demolished my well-loved green spot in seconds with a garden hoe. So I shall continue control the weeds in my tree pits, until the planted herbs look big and obvious.

Some treepits are full of well-tended, attractive and insect benefiting “weeds”. The biggest ones like this in my neighbourhood have handwritten signs tied to the tree trunks, stating that the pit is cared for and by whom. Good examples can be seen in Amsterdam on the corner of Hugo de Vrieslaan and Linneausparkweg and also along Balistraat (in Oost though they are in many areas). The plants can be up to 1.5m high and look like wild flower meadows.
