Prof. David Walsh, Ph.D.Proper aquatic plant care is essential for maintaining healthy ecosystems. Fertilization is applied to meet the specific needs of particular plants. Pruning encourages bushy plants. Water testing helps to prevent toxicity due to nutrient build-up.
Targeted Fertilization
- Use root tabs for heavy feeders like Amazon Sword every 3 months
- Apply liquid fertilizers after weekly water changes
- Supplement iron weekly for red-leaf species like Alternanthera
Strategic Pruning
- Cut stem plants above nodes at 45° angles
- Divide rhizomes keeping three leaves per section
- Thin floating plants weekly removing 30% coverage
Water Monitoring
- Test nitrate levels weekly keeping 5-20 ppm
- Check phosphate to maintain 10:1 nitrate ratio
- Monitor pH stability between 6.5-7.5
Light management prevents algae issues. Place plants according to their preferences. Floaters tolerate less light; low-light plants, such as Anubias and Java Fern, grow in shade. The medium-light plants need direct light. Limit the photoperiod to eight hours when establishing the tank. Floaters naturally strain intense light.
Propagation keeps a population up. Separate little plantlets of Java Fern when they reach one inch in height. Finger and thumb out stem cuttings and replant them immediately; the same applies to the runners of Cryptocoryne. Always have sharp scissors. Plants multiply, and if you take good care of them, they will keep your other tanks well-stocked.
Pay attention to health signals from your plants. If the leaves are yellow, it could indicate a nutrient deficiency. If growth is slow, it may be receiving inadequate light. If algae accumulates on the leaves, it's likely an imbalance. Adjust the routine to achieve the right balance, as your observations create suitable growing conditions.
