The future of gardens

It’s been weeks since my last blog. I started a few but they need some more thought so as a catch-up, here is a nice frivolous topic, recycled from 1998.

Surely gardens are a place to get back to nature, to escape from technology? Well, when journalists ask to see really advanced technology, I take them to the garden. Humans still have a long way to go to catch up with what nature does all the time. A dragonfly catching smaller flies is just a hint of future warfare, and every flower is an exercise in high precision marketing, let alone engineering. But we will catch up, and even the stages between now and then will be fun.

Advanced garden technology today starts and ends with robotic lawn trimmers. I guess you could add the special materials used in garden tools, advanced battery tech, security monitoring, plant medications and nutrition. OK, there are already lots of advanced technologies in gardens, they just aren’t very glamorous. The fact is that our gardens already use a wide range of genetically enhanced plants and flowers, state of the art fertilizers and soil conditioners, fancy lawnmowers and automatic sprinkler systems. So what can we expect next?

Fiber optic plants already  add a touch of somewhat tacky enchantment to a garden and can be a good substitute for more conventional lighting. Home security uses video cameras and webcams and some rather fun documentaries have resulted from videoing pets and wild animals during the night. There will soon be many other appliances in the future garden, including the various armies of robots and micro-bots  doing a range of jobs from cutting the grass every time a blade gets more than 3 cm long, weeding, watering, pollination or carrying individual grains of fertilizer to the plants that need it. Others will fight with bugs or tidy up debris, or remove dying flowers to keep the garden looking pristine. They could even assist in propagation, burying seeds in just the right places and tending them while they become established. The garden pond may have robot ducks or fish just for fun.

Various sensors may be inserted into the ground around the garden, or smart dust just sprinkled randomly. These would warn when the ground is getting too dry and perhaps co-ordinate automatic sprinklers. They could also monitor the chemical composition, advising the gardener where to add which type of fertilizer or conditioner. In fact, when the price and size falls sufficiently, electronic sensors might well be mixed in with fertilizer and other garden care products.

With all this robot assistance, the human may design the garden and then just let the robots get on with the construction and maintenance. Or maybe just download a garden plan if they’re really lazy, or get the AI to download one.

Another obvious potential impact comes in the shape of genetic engineering. While designing the genome for custom plants is not quite as simple as assembling Lego blocks, we will nevertheless be able to pick and choose from a wide variety of characteristics available from anywhere in the plant and animal kingdom. We are promised blue roses that smell of designer perfumes, grass that only needs cut once a year and ground cover plants that actually grow faster than weeds. By messing about with genes we can thus change the appearance and characteristics of plants enormously, and while getting a company logo to appear on a flower petal might be beyond us, the garden could certainly look much more kaleidoscopic than today’s. We are already in the era where genetics has become a hobbyist activity, but so far the limits are pretty simple gene transfers to add fun things like fluorescence or light emission. Legislation will hopefully prevent people using such clubs to learn how to make viruses or bacteria for terrorist use.

In the long term we are not limited by the Lego bricks provided by nature. Nanotechnology will eventually allow us to produce inorganic ‘plants’ . You might buy a seed and drop it in the required place and it would grow into a predetermined structure just like an organic seed, taking the materials from the soil or air, or perhaps from some additives. However, there is almost no theoretical limit to the type of ‘plant’ that could be produced this way. Flowers with logos are possible, but so are video displays built into the flowers, so are garden gnomes that wander around or that actually fish in the pond. A wide range of static and dynamic ornamentation could add fun to every garden. Nanotechnology has so many possibilities, there are almost no ultimate limits to what can be done apart from the fundamental physics of materials. Power supplies for these devices could use solar, wind or thermal power.

On the patio, there is more scope for video displays in the paving and walls, to add color or atmosphere, and also to provide a recharging base for the robots without their own independent power supplies. Flat speakers could also be built into the walls, providing birdsong or other natural sounds that are otherwise declining in our gardens. Appropriately placed large display panels could simulate being on a beach while sunbathing in Nottingham (for non-Brits, Nottingham is a city not renowned for its sunshine, and very far from a beach).

All in all, the garden could become a place of relaxation, getting back to what we like best in nature, without all the boring bits looking after it in our few spare hours. Even before we retire, we will be able to enjoy the garden, instead of just weeding and cutting the grass.

1998 is a long time ago and I have lots of new ideas for the garden now, but time demands I leave them for a later blog.
