Care Essentials
Get to Know Your Philodendron Selloum
A resilient houseplant. With basic care, Philodendron Selloum is hard to kill.
Light
medium to bright indirect
Most comfortable in medium to bright indirect light. Avoid prolonged direct sun exposure.
💡 Grow lights: Thrives under artificial grow lights (LED or fluorescent, 10-12 hours/day). A great option if your space lacks natural light.
Watering
every 7-10 days
Water when the top 1-2 inches of soil feel dry. Adjust with the seasons — less in winter, more in summer.
Humidity & Temperature
Not fussy about humidity. Handles average indoor conditions without issue.
Standard room temperature (60-80°F / 15-27°C) is perfect. Avoid cold drafts and sudden temperature swings.
Soil
Standard well-draining potting mix works well. Add perlite for extra drainage if you tend to overwater.

Nano-NPK at 3 mg/L produced +37
92%
How should I fertilize my Philodendron Selloum?

Solutions
- Prepare nano-NPK solution at 1-3 mg/L distilled water
- Spray leaf surfaces in early morning until runoff
- Repeat every 15-day interval during growing season
Prevention
Foliar spray every 15 days during active growth (spring-summer). Stop during winter dormancy.
Other Topics (5 topics · 5 cases)
Philodendron Selloum: Antioxidant Enzyme Elevation
Nano-NPK at 3 mg/L increased peroxidase activity by 106
94%
Philodendron Selloum: Antioxidant Enzyme Elevation
Nano-NPK at 3 mg/L increased peroxidase activity by 106
Cause
Nano-NPK at 3 mg/L increased peroxidase activity by 106.01% and catalase by 92.32% compared to control — nanoparticle uptake triggers up-regulation of antioxidant enzyme genes via reactive oxygen species (ROS) signaling cascades that activate POX and CAT transcription.
Solutions
- Foliar spray with 3 mg/L nano-NPK every 15 days during active growth
- Monitor POX activity target: >0.85 U/min/g protein (vs control ~0.4)
- Alternative: 2 mg/L nano-NPK + 3 mg/L nano-chitosan produces similar CAT elevation
Prevention
Apply 3 mg/L nano-NPK or 2 mg/L nano-NPK + 3 mg/L nano-chitosan every 15 days to maintain elevated antioxidant enzyme activity above 0.8 U/min/g protein.
Philodendron Selloum: Chlorophyll Enhancement
Nano-NPK and nano-chitosan treatments elevated chlorophyll a from ~1
95%
Philodendron Selloum: Chlorophyll Enhancement
Nano-NPK and nano-chitosan treatments elevated chlorophyll a from ~1
Cause
Nano-NPK and nano-chitosan treatments elevated chlorophyll a from ~1.0 mg/g to ~1.5 mg/g, chlorophyll b from ~0.35 to ~0.7 mg/g, and total carotenoids from ~0.25 to ~0.45 mg/g in Philodendron sellum — increases driven by enhanced nitrogen assimilation and Mg²⁺ uptake via nanoparticle-facilitated ion channels.
Solutions
- Apply 3 mg/L nano-NPK foliar spray every 15 days to maximize chlorophyll a (~1.52 mg/g)
- Alternatively use 2 mg/L nano-NPK + 3 mg/L nano-chitosan for chlorophyll b boost (~0.78 mg/g)
- Morning application ensures optimal stomatal uptake of nanoparticles
Prevention
Maintain 3 mg/L nano-NPK or 2 mg/L nano-NPK + 3 mg/L nano-chitosan every 15 days to sustain chlorophyll levels above 1.2 mg/g chlorophyll a.
Philodendron Selloum: Leaf Mineral Content
Nano-NPK at 3 mg/L elevated leaf N to 3
93%
Philodendron Selloum: Leaf Mineral Content
Nano-NPK at 3 mg/L elevated leaf N to 3
Cause
Nano-NPK at 3 mg/L elevated leaf N to 3.92%, P to 0.526%, K to 2.73% vs control (N 3.24%, P 0.462%, K 2.15%) — nanoparticle-facilitated nutrient translocation delivers minerals directly to leaf mesophyll via phloem, bypassing root absorption limitations.
Solutions
- Foliar spray 3 mg/L nano-NPK every 15 days for maximum leaf N, P, K content
- Target leaf N: 3.86-3.92% (vs control 3.24%)
- Target leaf P: 0.52-0.53% (vs control 0.46%)
- Target leaf K: 2.70-2.73% (vs control 2.15%)
Prevention
Apply 3 mg/L nano-NPK or 2 mg/L nano-NPK + 3 mg/L nano-chitosan every 15 days to maintain leaf N above 3.8%, P above 0.50%, K above 2.6%.
Philodendron Selloum: Nano Chitosan Photosynthesis
Chitosan nanoparticles (302
93%
Philodendron Selloum: Nano Chitosan Photosynthesis
Chitosan nanoparticles (302
Cause
Chitosan nanoparticles (302.6 nm) enhance photosynthesis by activating NO and H2O2 signaling pathways, closing stomata and increasing photosynthetic rate; they also promote phenolic compound synthesis and carbohydrate accumulation in plant cells.
Solutions
- Mix nano-chitosan at 1-3 mg/L in distilled water
- Apply as foliar spray in early morning until leaf runoff
- For synergistic effect: apply 2 mg/L nano-NPK, then 1 day later apply 3 mg/L nano-chitosan
- Repeat every 15 days during growing season
Prevention
Apply nano-chitosan as foliar spray at 1-3 mg/L every 15 days during active growth — bio-stimulant effect is most pronounced in spring-summer.
Philodendron Selloum: Root Growth Improvement
Nano-NPK at 3 mg/L increased root length by 94
94%
Philodendron Selloum: Root Growth Improvement
Nano-NPK at 3 mg/L increased root length by 94
Cause
Nano-NPK at 3 mg/L increased root length by 94.54%, root fresh weight by 57.44%, and root dry weight by 108.17% compared to control — nanoparticles translocate to root meristems via phloem and enhance cell division in root apical meristems through auxin-mediated pathways.
Solutions
- Foliar spray 3 mg/L nano-NPK every 15 days to maximize root growth
- Root length target: >65 cm (vs control 35.77 cm)
- Root fresh weight target: >125 g (vs control 82.59 g)
- Synergistic alternative: 2 mg/L nano-NPK + 3 mg/L nano-chitosan produces 65.26 cm root length
Prevention
Apply 3 mg/L nano-NPK or 2 mg/L nano-NPK + 3 mg/L nano-chitosan as foliar spray every 15 days to maintain robust root development.
