Feeding Cactus Seedlings: Wait Until Established, Then Go Light

Cactus seedlings in time-release mix need no extra fertilizer until well-rooted.

When to Start

• Wait until seedlings are established (several months).
• Time-release in mix is stronger than anything you'd add.

First Feeding

• 1 tbsp 1-7-6 per gallon water.
• Increase to 2 tbsp/gal later.
• Frequency: per label (typically every 2 weeks).

Key Rule

Cacti burn easily. Under-feed always.
