The Failure Archive: The Thornless Temptation​ - The Thornless Lie: Why My Soft Blackberry and Japanese Wineberry Died (And What Dryland Survival Taught Me) 💀


​In the early days of my Romanian food forest, I was seduced by convenience. Who wants to fight thorns? So, I eagerly planted thornless Blackberry cultivars and the visually stunning Japanese Wineberry (Rubus phoenicolasius). Both looked promising, offering sweet fruit without the battle scars.

​They both failed, and the lesson they left behind was brutal but essential: Thorns are not a burden; they are a sign of survival.

​The Problem with Pampering

​The thornless blackberry, bred for easy harvesting in gentle, moist climates, simply lacked the ruggedness needed here. The Rubus family, when domesticated for softness, often loses the crucial traits needed for arid resilience:

  1. ​Shallow, Thirsty Roots: The thornless varieties prioritize fast cane growth over deep, persistent rooting. They are dependent on frequent, shallow moisture. In my no-water system, they lasted until the first serious summer heatwave, then withered completely. They were asking for water I didn't have.
  2. ​No Defense Against the Sun: Thorns, along with dense, tough cane structure, naturally shade the stems and roots of wild varieties. The smooth, soft canes of the thornless cultivars offered poor natural defense against the sun-scald and wind-scouring that defines my landscape. They literally exposed themselves to destruction.
  3. ​The Wineberry Wipeout: The Japanese Wineberry, while beautiful, thrives in moist, open woodlands. It required far too much consistent moisture and light shade to thrive. When the shade from its neighbor didn't materialize fast enough, it turned brittle and died.

​The Lesson: Trust the Wild

​My native and naturalized, thorned wild roses (Rosa canina and R. rugosa) and my native Blackthorn (Prunus spinosa) thrive exactly where the pampered plants failed. Why?

  • ​They possess a massive energy reserve dedicated to deep rooting and thick, protective bark.
  • ​The thorns are a declaration: "I am protected, and I have reserved my energy for survival, not soft growth."

​The failure of the thornless blackberry and the wineberry was a painful, but vital, investment. It reinforced my core philosophy: when choosing plants for a dryland food forest, you must select for survival traits (thorns, tough leaves, dense structure) over human convenience (easy harvest, sweet taste).

​My focus is now firmly on the wilder, tougher members of the Rubus family—the ones that are genetically engineered by nature for adversity.

Growing Against the Odds: My Romanian Food Forest Journey

My food forest is based on a lot of mistakes - I bought the land, not as a plan to build a food forest, but simply to give me a greater distance from my neighbours. Romanians love nothing more than blasting out Romanian folk music on mobile speakers, which is is nice in the distance, as it gives the whole garden an ethnic sound track but up close, not a great idea. I hence has an overgrown, ancient orchard which hadn't been touched in decades, with brambles everywhere making it impossibe to enter or more around in. This is my starting point - oh and no running water on the site - any water I need requires me filling up a wheelbarrow with buckets of water and carrying them to the site.   My first investigations, started looking at Youtube videos - When I first imagined a food forest here in Romania, I pictured a lush, abundant garden — fruit trees heavy with apples and plums, shrubs spilling berries, and perennial herbs everywhere, all thriving together. The reality...

The 200km Rule: Why Climate Optimism Means Planting Trees from the South (Adaptation Strategy 2) 🌱

Climate adaptation is often discussed in terms of defense—building barriers, conserving water, managing collapse. While crucial, this reactive thinking misses the most powerful tool we have: long-term, strategic plant selection. ​Trees live for fifty, eighty, sometimes hundreds of years. The climate they will face a decade from now is not the climate they were selected for yesterday. To build true, lasting resilience, we must employ the 200km Rule. ​ Designing for the Future, Not the Past ​Climate models consistently show that plant hardiness zones are shifting poleward, bringing the challenging conditions of the south steadily northward. In my arid region of Romania, the climate of 2050 will resemble the climate found today approximately 200 kilometers south of my current location. ​Therefore, my adaptation strategy is one of climate optimism —I am selecting plants today that are already succeeding in tomorrow's predicted environment. ​ The Flaw of Localism: S...

January Gold: How I Turn Winter Prunings into Free Cuttings and Deer Protection for My Dryland Forest 🌲

January might look like the month of rest, but for me, it's the month of biomass gold . The trees and shrubs are deeply dormant, which means they are in the perfect state for renewal. I don't prune for shape as much as I prune for utility and resource generation. ​In my no-water system, nothing goes to waste. Every single cut branch or rod serves a purpose, turning what would be yard waste elsewhere into vital building materials for the food forest. ​ Pruning for Propagation and Expansion ​My first job is generating free plants . Dormant wood is the best for propagation, allowing me to expand my toughest species without spending a cent. ​ Hazel and Willow Rods: I make clean cuts on 20-30 cm lengths of young, straight hazel and willow branches. These are destined to be struck directly into the soil in spring. This is the cheapest, fastest way to thicken my windbreaks and ensure I always have replacement stock for the shrub layer. ​ Rose Suckers: I dig up suck...
