Minimal Fertilization:

Cacti have low nutrient requirements. Fertilize sparingly, typically during the growing season (spring and summer), using a diluted, balanced fertilizer.

Pruning and Grooming:

Regularly inspect your cacti for dead or damaged growth and remove it with clean, sharp tools. This encourages healthy new growth and prevents disease.

Pest Vigilance:

Keep a close eye on your cacti for signs of pests. Early detection is essential for effective pest control. If you spot any unwanted visitors, take swift action to address the issue.

Respect Their Space:

Give your cacti ample room to grow. Proper spacing allows for better air circulation and reduces the risk of disease and pest infestations.

Seasonal Adjustments:

Be mindful of seasonal changes in light and temperature. Adjust your care routine accordingly to provide the best conditions for your cacti throughout the year.
