Improve Your Food Forest Density

food forest density is a good thing
Food forest density is a GOOD THING! This photo is at Pilgrimโ€™s Farm – a very productive homestead.
Why is it that we find wandering through a lushย woodland a wonderful thingโ€ฆ yet fight against lush growth on our own properties?
In our yards we seem to have disconnected ourselves from natural ecosystems. Theyโ€™re scary I suppose. I mean, what would the neighbors think?
Our gardening is feeble and contrived, as ifย weโ€™re making mudpies in Godโ€™s driveway.
We clear and cut and till and plant at extension-approved intervals and spacings.
Some time back I created a big post at my site on growingย fruit trees from seed. One of the responses I get when I talk about seed-grown fruit is โ€œwhat if some of the trees make crummy fruit? I donโ€™t have space to grow trees from seed, only to have some of them turn out to be lousy!โ€
Trust me, unless youโ€™re in an apartmentโ€ฆ you have some space for seed-grown trees. Even for ones that donโ€™t turn out well.
Howโ€™s that?
Look โ€“ trees donโ€™t need as much space as you think they do โ€“ and trees with lousy fruit can always be grafted or cut down and composted. Or used to fuel a smoker or barbecue. Or cut and inoculated with mushrooms. Or cured and used for woodcarving.
Weโ€™re just too tentative in our gardening. Yes, sometimes you might plant things too close and end up with a tree (or three) thatโ€™s too shaded or too strangledโ€ฆ but you might be surprised how tight your spacing can get before a tree becomes completely unproductive.
Beyond just the trees, adding a larger number of plant species (basicallyย packing in lots of biomass!) will help build soil and create a lush and resilient ecosystem.
I have seen multipleย food forest projects that miss the benefits of density. Theyโ€™ve made the transition from standard annual gardening to a more permaculture approach; yet they look more like an orchard withoutย straightย lines than a species-rich forest edge.
Itโ€™s fine to start by planting trees and mulching away the grass around them โ€“ but once youโ€™ve got those trees as scaffolding, donโ€™t quit! Build density and youโ€™ll get more food and have less work in the long run. Food forest density is your friend.

Planting Around the Base of Trees

I use larger trees as shelters for my less cold-tolerant species. Iโ€™m growing guavas and pineapples in my front yard around the trunks of some large oak trees. Despite winter temperatures thatย occasionallyย reach down into the teens, they donโ€™t freeze to death. If I planted those pineapples out in the open, theyโ€™d be toast. The increased density of my yard allows them to grow where they normally wouldnโ€™t.
Some trees can also support climbing species. Iโ€™m growing yam vines up a small sweetgum seedling that popped up inย my food forest. The tree grew rapidly and I considered cutting it down to replace with something edibleโ€ฆ then I realized I should just take advantage of its quick growth and non-productive nature. I wouldnโ€™t grow yams on my prize Hachiya persimmon treeโ€ฆ but on a sweet gum? Who cares!
If you add nitrogen-fixers, nutrient accumulators and pollinator-attracting plants around your fruit trees, you can support those trees better than you could with just mulch. I also like to plant herbs, leaf crops, sweet potatoes and wildflowers.

Letting The Seeds Fall Where They May

EmergingSeeds1Sometimes I play seed fairy and throw handfuls of seeds all over the food forest. When Iโ€™ve got more time, I make seed balls and chuck those around.
Did weevils get into some of your dried beans? Donโ€™t throw them away โ€“ throw them in the food forest! The resulting bean plants will feed the soil, even if you never harvest them.
I once gave my children a bunch of old beans and told them to go have a bean fight in the front yard. Not only did they have funโ€ฆ they also scattered nitrogen-fixers everywhere!
Throwing seeds around lets nature pick and choose what works and what doesnโ€™t. I like a mix of flowers, brassicas, beans, grains and assorted tree seeds. Sometimes youโ€™ll have seeds coming up a year or more after you threw them. I can never remember what the heck Iโ€™ve planted so Iโ€™m often surprised by what pops up.

Start โ€˜Em and Stick โ€˜Em

Plants can be expensive. When you spend $25.00 on a tree, you donโ€™t really want to jam it into a shady corner and hope it survives.
I think economics are partย of the reason some of the food forests I see are so regimented. The spacing, the watering systems, the perfect mulch circles โ€“ they make sense when youโ€™re protecting an expensive investment.
I used to worry a lot about my trees. Now that I have a nursery and do a lot of propagation, I donโ€™t worry as much.
When you start your plants from seeds and cuttings, theyโ€™re more expendable. You just donโ€™t have that much money out there. It costs pocket changeย for decent dirt and old coffee cans and milk jugs can be pressed into service as pots.
Buy a couple of healthy plants from nurseries, then start a lot of babies from those initial purchases…
