Lazy gardening - the sustainable perennial garden

As  much as I enjoy working in the garden, life and time can get away from me.  I've been on a mission the past couple years to develop a vegetable garden that is not only self sustaining and a prolific producer, but one that will require only minimal effort on my end to thrive.  I'm experimenting now to find what does and doesn't work for me, and will carry this experience over to my off grid garden when I make my final move. 

I will continue to expand and update this list, so be sure to keep checking back!  

#1  Top of the list is Asparagus.  I started with three year old crowns - the root system of a mature plant.  These went directly into a permaculture bed up close to a fence.  As the plant matures through the season it sends up beautiful fern like shoots and creates a natural, ferny hedge.  the taller the ferns, the bigger your harvest will be the following year.  Asparagus is a heavy feeder and requires lots of fertilizing.  I've found that by composting each year and throughout the growing season, my Asparagus does well enough.  Occasionally I will mix up some fish emulsion and give the plants a little drink.  

#2  Jerusalem Artichoke.  A delicious substitute for potatoes and a perennial that requires next to zero maintenance.  A member of the sunflower family, this plant will grow upwards of 6' and produces pretty yellow flowers.                                                                                                                                                                                    
 I use these not only as a potato replacement but as a natural privacy fence around my property.  They're certainly pretty enough to disguise the fact they're part of my "farming".  The tubers can be prepared in much the same way as potatoes.  Raw they taste similar to a water chestnut.  A word of caution - these can become invasive, so unless you want them growing everywhere, you might want to section off a specific area for them or grow them in large containers. You won't be disappointed in the harvest from these tubers, they are prolific!  

#3 Walking Onions.  I can't say enough about this onion variety, from the ease in planting and harvesting to how hardy these onions are.  All parts of the plant can be used.  The bulblets on top, the green stems (like chives or green onions) and the bulb beneath the dirt.  Such a versatile, flavorful addition to the homestead.

#4  Strawberries.  No garden would be complete with this delicious addition.  Strawberries can live for many years , dying back in the winter, to reemerge in the spring.  Since they propogate through runners and seeds, a strawberry garden can grow and live indefinitely.  Admittedly, I'm successful at everything I grow, and I have successfully killed all of my strawberry plants for years.  I'm keeping my fingers crossed that I figure out the issue and somehow keep them alive this year.  I'm open to tips and tricks, so if you have some, drop me a comment!


#5 Taro.  I was told Taro wouldn't grow in this climate, but here I am, growing it.  Not only will it grow, but it will survive overwintering in the ground, and it comes back early in the spring. Be sure to mulch it with a good 6" of mulch in the fall (after cutting it back to the ground).  The roots/tubers are a wonderful substitute for potatoes.  Not as prolific as the Jerusalem Artichoke, but it's nice to have options.  

#6 Saffron Crocus.  Saffron is the world's most expensive spice (by weight), but it's one of

the easiest spices to grow. To plant saffron crocus, start with high quality corms. These can be purchased from several different online companies.  Choose a planting site that is well drained and has soil rich in organic matter.  Plant in the spring or early fall, to a depth of 4 to 6".  when the flower blooms in the autumn, the orangish-red stigmas are plucked from the flowers.  air dry for a few days before storing.   

#7 Ginseng.  I was told repeatedly this wouldn't grow in my zone, and against all nay sayers, it's not only growing, but thriving.  I started with 3 year old roots that I ordered online.  Each winter I cover the bed with a good 6" of leaves to protect them against the cold The leaves break down through the seasons, creating a nice compost and fertile soil for the roots.  Research what ginseng needs to grow and create your own "micro-climate".  Rules were meant to be broken, right?

#8 Turmeric and Ginger.  Turmeric and Ginger grow in the same manner with very similar needs.  Once you figure it out, they're both relatively easy.  I recommend growing in planters or big pots, because they really don't overwinter well in many climates.  I'll post specifically about growing these two tubers, complete with photos to help explain the process.  Keep checking back and I will provide a link here with the instructions.

#9 Malabar Spinach.  This is actually an edible ornamental, so don't hesitate to use it in some of your landscaping/yardscaping.  Since it vines, it's beautiful kept in a container with a trellis.  The thick, dark green leaves provide tasty greens throughout the summer, when traditional spinach will not grow. The mild flavor makes Red Stem equally good cooked or fresh.  Children often prefer this variety over the cooler season spinaches.

As you can see in the below photograph, this vine gets tall.  About 6' of vertical salad, right at your fingertips! Perfect for container gardening when ground space is limited.
