Malta-Specific Growing Challenges
Water pH Issues
Problem: Malta's tap water is highly alkaline (pH 8.0-8.5)
Solutions:
- Always pH test water before use
- Use pH Down (phosphoric acid) to adjust to 6.0-6.5
- Consider RO water for sensitive plants
- Monitor nutrient lockout symptoms
Malta Tip: Buy pH testing drops from local hydroponic shops in Msida or Birkirkara
Limestone Soil
Problem: Rocky, alkaline soil with poor drainage
Solutions:
- Use containers with quality potting mix
- Add perlite for drainage (20-30%)
- Choose acidic amendments (peat moss, compost)
- Avoid digging into native limestone
Malta Tip: Source soil amendments from Garden Centre Tal-Barrani or similar local suppliers
Scirocco Winds
Problem: Hot, dry winds from Africa (35-40°C+)
Solutions:
- Create windbreaks with screens
- Move containers to sheltered areas
- Increase watering frequency during winds
- Use humidity domes for young plants
Malta Tip: Monitor Malta weather forecasts for scirocco warnings
Common Malta Pests
Problem: Spider mites, aphids, whiteflies thrive in Malta's climate
Solutions:
- Regular inspection (weekly minimum)
- Neem oil treatments (early morning/evening)
- Beneficial insects (ladybugs, lacewings)
- Sticky traps for monitoring
Malta Tip: Buy neem oil from Pharmacies or agricultural suppliers in Mosta
