Indoor Plant Food Spikes
Miracle Gro Indoor Plant Food Spikes deliver a slow supply of nitrogen, phosphorus, and potassium. They work for low-maintenance feedings of pothos, snake plants, ZZ plants, dracaena, and similar houseplants.

• Replace every 30 to 60 days.
This supports steady foliage growth without the risk of overfeeding that comes with liquid products.

• Mixed planters that contain multiple species with moderate nutrient demand.
Application
• Mix the measured powder into water and feed every 1 to 2 weeks during active growth.
• Reduce or stop feedings during winter dormancy.

Application
• Feed every 7 to 14 days during spring and early summer.
• Use distilled or rainwater if your tap water is highly alkaline.
• Do not combine with lime or other materials that raise soil pH.
Vegetables
Tomato Plant Food
Tomato Plant Food provides a nutrient ratio that supports strong root development, flower formation, and fruit production. It works for tomatoes, peppers, cucumbers, squash, and similar warm-season crops.
Application
• Begin feeding once plants are well established.
• Apply every 7 to 14 days according to the dilution rate listed on the label.
• Combine with consistent watering to prevent blossom end rot, which is driven by calcium movement rather than fertilizer content but is affected by moisture swings.
