Tara became involved with grafting ‘guerrilla style’ after she was unable to get permission to plant productive fruit trees in front of her own house. The city administrators cited concerns about maintenance and liability. She was willing to assume responsibility for these but the city still refused, which she found unreasonable. Tara further discovered that it is simply city policy to not allow fruit producing trees, but apparently no formal law exists prohibiting them.

The Guerrilla Grafters’ goal is to demonstrate that with proper care, fruit trees are not a nuisance and in fact add to the quality of life in the urban environment. In Tara’s view, fruit trees on private property are more likely to suffer from neglect when the owners no longer want to care for the tree or harvest the fruit or when new tenants arrive and are not interested in the trees’ upkeep. This is why the Guerrilla Grafters won’t graft a tree that doesn’t have a committed caretaker. Trees in public spaces have the advantage of being accessible to a number of people that can take over as caretakers when the need arises, and the public can harvest the fruit.

In fact with a little effort, a city with fruit trees can be a food forest.

Social Change Through Fruit Trees

Tara expressed concern that the public at large is disconnected from public spaces. This disconnect arises in part because citizens don’t have any responsibility in the public space. She explained that the Guerilla Grafters hope to instill ‘a sense of responsibility to care for what is in the public realm’ through the act of ‘editing’ their neighborhood space by grafting.  But she clarified that they are ‘not necessarily for (citizen) responsibility without participation in the decision-making.’

Beyond grafting for fruit production, caretakers and grafters make the effort to see that the trees are pruned and watered as needed and keep them healthy. They are invested in an activity that is ultimately a public good.

Data Gathering in San Francisco’s Microclimates

Another interesting piece to the Guerrilla Grafters’ mission is that they are beginning to collect data about the trees they have grafted. They want to monitor how well the trees produce certain varieties of fruit, including the quality. The results of this research should be helpful for urban gardeners in San Francisco, which is well known for its varied microclimates. She is seeking help with their Web site to enable this data-gathering project.

The Grinch Who Hacked Trees

Sadly, they recently discovered that the trees they grafted in the Hayes Valley area of San Francisco were severely pruned, including all of the grafted branches. This was unnecessary solely for ‘pruning” purposes.’  They lost all of the grafted Asian pears that were ripening there.

Apparently the now popular YouTube video about the grafters inadvertently gave away the location of these grafted trees. The video was never meant to circulate widely and advertise their activities. It was made for a demonstration the Guerilla Grafters were giving at a conference, but they never even used it.

They’ll be more careful next time, Tara assures.
