I really wish I had more time to work around the homestead. There are so many things I need to get done and not enough hours in the day. Here are a few things I have planted that don't take a lot of maintenance.
Asparagus (Asparagus officinalis) is so easy to grow. I mean it is almost effortless. The only catch is you have to let it establish a good root system before you can harvest from it. Most recommendations are to let it grow for 2-3 seasons before you harvest. I let ours go for three springs before I harvested. This plot has 10 crowns that I planted 4 years ago. I have 20 more crowns I just got in the mail. I need to find two more good spots, away from this one, so pests have a harder time moving around. Asparagus will produce for 30 years or so. Make sure you get yours in this year.
This is a Chicago Fig (Ficus carica). It is supposedly hardy to zone 5. I had another "cold hardy" fig that I lost over the harsh winter we just went through. I am pretty sure we just had a zone 5 winter. I hope this fig will do better than the one I lost.
Another plant and forget perennial is the Filbert (Corylus americana) or American Hazelnut. Pictured behind our puppy who was behaving in a rare moment of calm. I have 12 planted in the back yard and another hedge of 10 planted in the front yard. The trick is to get to the nuts before the critters do.
