12. Cocoa Shell Mulch
Cocoa shells are a great mulch choice for tomatoes. They decompose slowly, providing long-term nutrient release. They also help retain soil moisture and prevent weeds.
13. Coffee Grounds
Coffee grounds are a good source of nitrogen and improve soil drainage. They can be mixed into the planting hole or used as a surface mulch to deter pests like slugs.
14. Eggshells
Eggshells are rich in calcium, which helps prevent blossom end rot in tomatoes. Crushing them and adding them to the planting hole can help provide a steady supply of calcium to your plants.
15. Fish Emulsion
Fish emulsion is a liquid fertilizer made from fish byproducts. It’s high in nitrogen and other essential nutrients and can give your tomatoes a quick boost, especially during early growth.
16. Mycorrhizal Fungi
Mycorrhizal fungi form a symbiotic relationship with tomato roots, improving nutrient and water absorption. Adding these fungi to the planting hole can enhance root health and stimulate vigorous plant growth.
17. Alfalfa Meal
Alfalfa meal is a natural source of nitrogen, calcium, and trace minerals. It helps boost overall plant health and can improve the flavor and texture of tomatoes.
18. Humic Acid
Humic acid helps improve soil structure by increasing its water-holding capacity and nutrient content. It also stimulates beneficial microbial activity in the soil, enhancing tomato plant growth.
19. Peat Moss
Peat moss helps retain moisture and improve soil aeration. It’s an excellent additive for tomatoes, especially in sandy or dry soils, as it helps maintain consistent moisture levels.
20. Superphosphate
Superphosphate is a concentrated source of phosphorus, which is essential for strong root systems and early flower and fruit development. It’s especially useful for tomato plants that need extra phosphorous for better production.
21. Green Sand
Green sand is a mineral-rich additive that improves soil fertility. It contains potassium, iron, magnesium, and other trace elements, all of which help improve the health and flavor of your tomatoes.
22. Molasses
Molasses can be used as an organic sugar source that promotes the growth of beneficial soil microbes. It helps boost microbial activity in the soil, enhancing nutrient uptake and overall plant health.
23. Organic Mulch
Organic mulch, such as straw, leaves, or grass clippings, helps conserve moisture, suppress weeds, and regulate soil temperature. It also adds organic matter to the soil as it decomposes, benefiting tomato growth.
By adding the right mix of additives to your tomato planting holes, you create the ideal environment for optimal growth and a flavorful harvest. Just be mindful of the specific needs of your soil and the variety of tomatoes you’re growing to ensure you provide them with exactly what they need. Happy gardening!
