The gardens in Hamilton feature all the main garden design styles, from Italian renaissance to Japanese to English cottage garden and American modernism, but they also have an excellent range of ideas for Kiwi backyards, including a permaculture garden, so I thought let's talk about simple ways to be a bit more sustainable in your back garden:
1. As the calendar ticks over into spring, and you suddenly start buying lots of plants in plastic pots, ask your local garden centre if they offer recycling. Many will have a collection area for pots to be recycled. Or, stack them up neatly and use them when sowing seeds or taking cuttings or potting up divisions of your favourite plants to share with others. Don't just biff them in the rubbish.
2. Making compost is a no-brainer but it can be quite difficult in a small garden. An easier, no-fuss, no-stink way to recycle kitchen scraps is to dig a long trench across your vegetable garden, about 30cm deep, and bury your scraps in a layer 10cm deep. Cover with soil and plant salad greens and leafy vegetables on top.
3. Wilt your weeds before you compost them. If you attack your garden in a gung-ho, get-it-all-done-in-one-weekend sort of fashion, you invariably end up with a huge pile of green waste that fills your entire compost heap. So, if you have a concrete path or driveway, dump the weeds on that for a week until they wilt; they'll shrink in volume by a third, then put them in your bin. Or rot weeds down in a barrel of water with some comfrey and seaweed and chook manure to make liquid fertiliser.
4. Reserve an area for bee and beneficial insect fodder, which means flowers. Chuck in a packet of wildflower seeds and let them go to it.
5. Don't spray. Or if you do spray, choose more natural options.
And if any of you have burning horticultural questions, bring them along to the Get Growing Roadshow from 11am today and tomorrow at Hamilton Gardens and Lynda will hand out some free advice.
