nutrient deficiency
Description
This entry documents physiological nutrient deficiency symptoms observed in Trichocereus cultivars (such as Landfill x Ogun). Affected specimens exhibit a distinct loss of deep green coloration, with the epidermis turning a lighter lime-green shade. Growth may become noticeably skinnier than normal, though the plant's overall vitality remains intact, often continuing to grow and producing healthy basal offsets (pups).
History & Origin
Nutrient deficiency is a physiological disorder rather than a specific clone. The discussion surrounding these symptoms arose in the community regarding a Landfill x Ogun specimen cultivated by Somanyhobbies in North Florida, which exhibited lime-green coloration and skinny growth compared to the rest of their collection.
Cultivation Notes
* Soil Composition: High inorganic content (pumice, perlite, gravel) can lead to rapid nutrient washout, especially in areas with frequent heavy rain. * Watering & Flushing: If nutrient lockout is suspected, flush the substrate thoroughly with water adjusted to a pH of 6.5. * Fertilization: Apply fertilizer very lightly. Avoid overfeeding or applying heavy treatments during cold weather. Wait until sustained warm weather (spring or warm winter windows) to feed. * General Guidance: Maintain standard care for Trichocereus pachanoi/hybrids; some plants may naturally resolve growth issues and throw healthy basal pups without drastic changes.
Community Discussion & Citations
Analysis of the discussion. The community discussed a specific Landfill x Ogun plant showing lime-green coloration and skinny growth. Aay Jay pointed out that highly inorganic soil mixes can cause nutrient deficiency, particularly under heavy watering or rain. Ken Sohn advised caution, recommending light feeding only when warm weather permits and warning against the common pitfall of over-fertilizing. Somanyhobbies shared their local North Florida climate challenges and their flushing protocol. Ben Garland provided a comparative observation of an Ogun x Jessica seedling that exhibited similar lime-green, skinny growth but successfully produced basal pups under standard care.
| Date | Speaker | Confidence Score | Key Insight/Quote |
|---|---|---|---|
| 2026 (approx) | Aay Jay | 7 | “That’s a lot of inorganics in your soil, unless you're in an area with frequent heavy rain. I'd agree that it's probably hungry” |
| 2026 (approx) | Ken Sohn | 7 | “It seems lacking some nutrients but, I wouldn’t feed till spring depending on where you live and the placement of the plant itself. If so I’d feed very lightly.” |
| 2026 (approx) | Somanyhobbies | 6 | “I flushed it today with a ton of water ph’d to 6.5. Wednesday it’s supposed to warm back up for a couple weeks. I’ll lightly feed it then.” |
| 2026 (approx) | Ben Garland | 7 | “I have an Ogun x Jessica seed grown that has had more of a lime green colour like your Landfill x Ogun. It is one of my favorite plants that has grown probably the most skinny in my collection. … It has now thrown basal pups so no real concern.” |
Credibility Notes
Aay Jay and Ken Sohn are rated highly (7/10) due to their practical, consistent advice on soil dynamics and seasonal feeding strategies, which align with standard horticultural practices. Ben Garland (7/10) provided valuable comparative cultivation data from a similar hybrid cross. Somanyhobbies (6/10) provided detailed environmental context and specific pH parameters for their flushing routine.
