Update April 15 2025 Young Oak Trees Thessaloniki

These were the first acorns we planted near Thessaloniki.

Two or three years old now, growing strong among the pine trees and nestled in a bed of needles.

The pine forest near Thessaloniki is on borrowed time. Either fire or disease will destroy them.

It would be prudent if we started an intensive acorn planting project.

Unfortunately we don't have blue jays around here doing the planting for us.

-------------

It seems that pine trees and young oak trees may share a symbiotic relationship.

The young oaks appear to thrive beneath the pines, and it’s possible that the pines help provide them with water and other resources essential for survival.

In southern Greece, near Sparta, we planted a few acorns in the winter of 2023, placing some beneath pine trees.

Remarkably, despite the summer of 2024 being one of the hottest and driest we’ve ever seen, those young oaks planted under the pines all survived.

This suggests that there may indeed be a beneficial interaction between the two species.

This year, we also visited the islands of Crete and Rhodes, which lie further south and may even be in a different time zone.

While there, we planted a few acorns to see how they would fare in the local climate.

We’ll provide updates on their progress once we have more information.

The first report, expected in June or July, will indicate whether the acorns have sprouted. A second report will follow in January to assess their condition, with a final update planned for spring 2026.

Greetings to all,

We’re currently working on our community Food Forest project. If you look back at one of our earlier videos, you'll see that the land is divided into two distinct sections. The northern part is mostly bare, while the southern part has patches of organic matter and some grass cover. However, both the northern and eastern edges remain largely exposed, with bare soil.

See


We’ve started planting trees—some from bare roots and others from seeds—but we're concerned that their growth will be slow due to the soil's low organic matter content.

We’re facing several limitations in addressing this issue. We don’t have access to tractors or mechanical tools to sow ground cover or green manure crops. On top of that, this site is far from our main farm, which makes transporting materials like clay seed balls a logistical challenge.

Because of these constraints, we’re exploring a more straightforward method: directly scattering seeds on the soil’s surface. I’ve never tried this before, and I don’t know many people locally who have either—so we’re entering uncharted territory.

There are, of course, challenges with this method.

The first issue is ants. Ants are a formidable force. If you scatter seeds on the ground during summer, they’ll quickly haul them away. Through observation, however, we’ve learned that ant activity significantly decreases in December, January, and early February. They essentially go into hibernation during this time, at least in our region. This might not apply everywhere—places like Northern Africa or Mexico may not see the same pattern—but here, it's a window of opportunity.

Another helpful discovery involves seeds like vetch. Ants struggle to carry vetch seeds because they're round and smooth, making them hard to grip. This makes vetch ideal for fall planting. It also produces a lot of organic matter and fixes nitrogen, which is essential for improving our soil.

Birds present another challenge. Imagine scattering 20 kg of barley, only for a flock of birds to feast on it in a matter of hours. Timing is everything—if you sow seeds in December, when most local farmers are planting too, there’s a better chance that birds will be distracted by other fields. That’s what happened this year, and we got lucky.

Weather can also work against us. Heavy rain can wash seeds away. Strong winds might blow them off the surface. Another scenario: seeds sprout after a few days of rain, but then the sun comes out, temperatures spike, and the young roots dry up before they reach moisture deep in the soil.

Despite all these challenges, with smart planning—and a bit of luck—we believe we can establish ground cover crops that will protect and nourish the soil.

Persistence is key. Take advantage of every rainy spell to scatter seeds—success comes through repeated sowing.

Knowing which plants can take root on bare soil is crucial, and this will vary by region. For us, barley was the first test crop. We chose it because we’d noticed wheat left behind on the ground surface, after harvest, often sprouted in the fall rains. So, in early December, while others were plowing and planting their winter grains, we began scattering barley. We continued through the rainy spells of December, January, and February. The barley we used was animal feed grade, so it was relatively inexpensive. And it worked—just a week of cold, rainy weather was enough for it to take root and begin establishing.

Mustard seeds have also performed very well. They grow like weeds in our region—which, in this case, is exactly what we want.

We’re now testing other fast-sprouting, fast-rooting plants like arugula, Mediterranean hartwort, sorghum-sudangrass, chia, millet and flax seeds. The goal is to identify species that not only grow quickly but thrive in our specific conditions.

In areas that already have some ground cover—even if it’s just grass or invasive Bermuda grass—simply scattering vetch or field peas can yield good results.

Long-term, plants like alfalfa and sainfoin that stay green through the summer are especially valuable. Alfalfa, in particular, is our top priority.

Once we manage to establish even a light ground cover, we can come back the following year and scatter more beneficial plants like vetch and peas.

This method—of growing on bare soil—has huge potential. It could be used after wildfires to prevent erosion, with seeds scattered by drones, helicopters, or volunteers.

It also opens up a path to restoring marginal lands and making them productive again.

Planting alfalfa and similar crops can help cool the planet and capture carbon. Monoculture tree crops like olives, grapes, and almonds thrive best with permanent green cover beneath them—alfalfa is an ideal choice.

As the wise and beautiful Wangari Maathai from Kenya once said, the Earth is a beautiful lady who loves to be dressed in green.

If we can establish this simply by scattering seed, it’ll save time and resources. It’s easy enough to broadcast vetch, field peas, and other cover crops directly into an existing alfalfa base.

Watching these plants grow on the Community Food Forest, has been rewarding.

We’ll be observing closely through spring, summer, and the seasons ahead to see how it all unfolds.

Whether this project succeeds or not remains to be seen.

But despite the obstacles, it's an effort worth making—the potential rewards are substantial.

This is an update.

We started planting seeds at this site south of Thessaloniki 11 years ago.

In one spot where we had the right conditions, rich soil, and full sun, the almonds trees have fully grown and are producing almonds.

Most of the land however is unsuitable for the prunus family trees.

In addition the pine trees, like weeds have overtaken the land.

We are currently planting acorns in between the pine trees and the rest of the site,

Its interesting to see the cactus doing so well at the southern side.
It maybe useful in reforesting areas close to the deserts.

Greetings to all.

We are working on improving the soil in the community food forest project.

This project will force us to find ways to keep our soil covered all summer long with
plants that hopefully fix nitrogen and improve the soil with organic matter.

It's a difficult if not impossible situation.

If anyone has any ideas....

If a solution is found, it's applications are many and benefits impactful.

Congratulations Eric,

I imagine your delight in seeing this tree emerge.

I hope you will experience this many many times in the future !!!

Greetings to all, and a happy new year.

We have three small vids with updates.

The first, is an update on the use of the battery operated blower to help plant green manure crops.



The second is on the use of surface scattered barley to help cover the bare soil of our community food forest.



And the third is about the nitrogen fixing shrub called anagyris foetida (stinking bean trefoil). For many years, I thought this was called laburnum.



Our reforestation efforts have moved to southern Greece, around the city of Sparta, and soon they will start at the island of Crete.

As we move south, the young trees will be further stressed by the lack of rain and high temperatures.

The first preliminary results from Sparta are encouraging, but it is too soon to reach conclusions.

Blower

We've started using a battery-operated blower machine on our farm, powered by free energy from our solar panels. This powerful blower helps us plant seeds in areas with thick, tall grass. When scattering seeds like vetch or field peas, we worry they won't reach the soil to sprout and grow. Ideally, we want them to be as close to the soil as possible.

We could use a gasoline-powered weed trimmer to cut the grass down to the bare soil, then spread the seeds and cover them with the grass clippings. However, this requires gasoline, time, maintenance, and oil expenses. If successful, the blower could eliminate the need for the trimmer, making the process easier and faster.

Whether this method will work and how well the vetch and field peas will grow above the grass remains to be seen.

It's going to be interesting to see if the vetch and field peas can smother the grass and thrive.

Barley

We are at the new community forest we are working on. The northern section of the land remains bare, with limey soil that stays largely uncovered year-round. We've been planting seeds and have several young trees, one to two years old. However, the soil lacks the organic matter needed to help these young trees grow quickly. Our goal is to cover the earth with a layer of organic matter.

The land is only accessible on foot, so mechanical equipment can't reach it, and we prefer not to plow and disturb the soil. Our plan for this winter and into spring is somewhat risky, as it could fail in many ways. We've begun broadcasting barley on the bare soil, scattering the seeds closely spaced on the ground.

We had some rain last night, and our concern is that heavy rain might wash the seeds away, or birds might collect them.

Besides the heavy rains and the birds, we are also concerned about the sun and wind. If the rain stops or it becomes very windy, the seeds may dry out and fail to take root and grow.

These are the conditions we're working with, and if this batch of barley fails to root, we'll try again when the weather is favorable. If rainy and cold weather is forecasted for one or two weeks, we'll give it another shot. We are committed and won't give up after just one try.

If, by some miracle, the barley starts to grow and reaches 5 to 10 cm in height, it will protect the ground from the sun and wind. We then plan to scatter vetch, field beans, and fava beans, hoping that the barley will provide a protective environment for these nitrogen-fixing plants to grow vigorously, covering the land and adding organic matter. We may also scatter small seeds like alfalfa or daikon to assist the process.

Whether this plan will work or not remains to be seen, but it's worth a try. The cost of the barley seeds is small as we bought them from an animal feed store and they're not certified seeds—just as long as they sprout, we don't mind. It will be interesting to see how this experiment goes, but we are hopeful that it will speed up the rehabilitation of this land. We are keeping our fingers crossed for the best outcome.
