What Fertilizers to Use for Tomatoes in August 2025

Coffee Grounds

Ground coffee mixed with water can be used as a safe fertilizer for tomatoes. This solution contains phosphorus, potassium, nitrogen, and microelements that improve the growth and sweetness of the fruits.

Mineral Fertilizers

For tomato bushes, potassium monophosphate or superphosphate mixed with water can be used. This will improve the quality of the fruits and make them sweet.

Organic Fertilizers

Compost, rotted manure, and humus are beneficial for improving tomato yields. Wood ash, which contains potassium, can be used as a top dressing or solution for fertilizing plants.
