5 Tips and How to Make Homemade Fertilizer for Your Garden

Homemade fertilizer

Every garden blooms with love, attention, and the right nourishment. While there’s a plethora of commercial fertilizers out there, there’s a unique sense of accomplishment in creating your own.

Making your own fertilizer can be economical and environmentally friendly. In this guide, we’ll explore some easy ways to craft nutrient-rich blends right at home.

Kitchen Scraps: The Natural Compost

Every kitchen is a goldmine of potential nutrients for the garden. Instead of throwing away your kitchen waste, consider composting or directly incorporating certain scraps into your garden soil. Here’s how:

• Banana peels: These are a powerhouse of potassium, an essential nutrient that aids in flower and fruit production. To use, you can either chop them up and bury them a few inches into the soil or dry and grind them to use as a sprinkle-on fertilizer. Over time, they decompose and release potassium, ensuring that your plants stay vibrant.

• Eggshells: These are primarily made of calcium carbonate, a compound that plants use to build strong cell walls. To harness their benefits, crush the eggshells into a fine powder (you can use a blender or mortar and pestle) and sprinkle them around the base of plants. They not only provide calcium but also help aerate the soil and deter certain pests, like slugs and snails.
  
• Coffee grounds: If you’re a coffee lover, your plants can be too! Coffee grounds are rich in nitrogen, a nutrient essential for leafy growth. They also help to acidify the soil, making them a perfect addition for acid-loving plants like roses, blueberries, and azaleas. Before using, ensure the grounds are cool. You can sprinkle them on top of the soil or mix them into compost. However, use them sparingly as excessive amounts might lead to soil compaction.
  
• Vegetable scraps and peels: While it’s common to throw these into the compost bin, you can also use them directly in garden trenches. Dig a trench about a foot deep, lay the scraps, and cover with soil. Over time, they’ll break down and enrich the soil. This method is particularly useful for root vegetables that benefit from the added nutrients at a deeper soil level.
  
• Tea bags: After brewing your favorite cup, don’t throw away those tea bags. Open them up and sprinkle the contents around plants. Tea leaves contain tannic acid and other nutrients beneficial for the garden. Just ensure the bag material is compostable if you plan on burying the entire bag.

Epsom Salt for a Magnesium Boost

Epsom salt, scientifically known as magnesium sulfate, isn’t your typical table salt. Instead, it’s a naturally occurring mineral that has been a secret weapon of many gardeners for years. Here’s why and how to use it in your garden:

Why Magnesium is Important:

• Magnesium plays a critical role in photosynthesis, aiding in the creation of chlorophyll, which plants use to convert sunlight into food. A deficiency can lead to yellowing leaves, reduced fruit production, and a general decline in plant health

Benefits of Epsom Salt:

• Improved Seed Germination: Using Epsom salt during the germination process can lead to stronger seedlings. It aids in the strengthening of cell walls, ensuring that young plants have a strong start.
• Enhanced Nutrient Absorption: Magnesium can help plants absorb vital nutrients, like nitrogen and phosphorus.
• Flowering and Fruit Production: Plants supplemented with Epsom salt often produce more blooms and fruit due to improved chlorophyll production.

How to Use Epsom Salt:

• Soil Amendment: Before planting, you can mix 1-2 tablespoons of Epsom salt per gallon of soil.
• Foliar Spray: Dissolve a couple of tablespoons of Epsom salt in a gallon of water and use it to spray plants every few weeks.
• Direct Application: For plants already established, sprinkle Epsom salt around the base of the plant once a month.

Safety and Considerations:

• It’s essential to note that while Epsom salt can be beneficial, it doesn’t replace a balanced soil nutrition plan. Overusing it can lead to salt build-up and imbalances in soil nutrients. Always conduct a soil test before heavily amending your garden soil with Epsom salt or any other additives.

Wood Ash: Nature’s Lime Substitute and a Homemade Fertilizer Ingredient

Derived from the burnt remains of wood, wood ash has been used for centuries as a valuable homemade fertilizer to enrich garden soils. Packed with vital nutrients and acting as a natural liming agent, it’s a sustainable addition to the garden. Here’s a closer look at its benefits and usage:

Benefits of Wood Ash:

• Rich in Potassium: One of the primary components of wood ash is potassium, a nutrient essential for flower and fruit production in plants.
• Raises Soil pH: Acting as a liming agent, wood ash can help neutralize acidic soils, making them more favorable for a variety of plants.
• Supply of Trace Elements: Besides potassium, wood ash contains traces of other minerals like calcium, magnesium, and phosphorus, making it a multifaceted homemade fertilizer.

How to Use Wood Ash in Your Garden:

• Direct Application: You can sprinkle cooled wood ash directly onto your soil. However, it’s vital to distribute it evenly and not pile it up, as excess application might lead to nutrient imbalances.
• Compost Enhancer: Mixing wood ash into your compost pile can help enrich the final compost mix, turning it into a potent homemade fertilizer.
• Pest Deterrent: A light sprinkling of wood ash around plants can deter pests like slugs and snails.

Safety and Considerations:

• Use Sparingly: While wood ash can be an excellent soil additive, excessive use can lead to high soil alkalinity. It’s essential to test your soil’s pH before making any significant amendments.
• Avoid Treated Wood: Ash from treated or painted wood can contain harmful chemicals and should never be used in the garden.
• Storage: Store wood ash in a dry place, as when exposed to moisture, its nutrient value diminishes.

Grass Clippings and Leaves: A Green Boost for Homemade Fertilizer

Often overlooked, grass clippings and fallen leaves are valuable, organic additions to our gardens. They’re abundant, renewable, and packed with nutrients. Here’s how to harness their potential in your homemade fertilizer mix:

Benefits of Grass Clippings and Leaves:

• Nitrogen-rich: Grass clippings are particularly high in nitrogen, an essential nutrient that promotes lush, green growth in plants.
• Natural Mulch: Both grass clippings and shredded leaves can serve as a mulch, helping retain soil moisture, suppress weeds, and regulate soil temperature.
• Soil Enrichment: Over time, as they decompose, these organic materials release nutrients back into the soil, enhancing its fertility and structure.

Using Grass Clippings and Leaves in Your Garden:

• Direct Mulching: Fresh grass clippings can be spread thinly over garden beds. However, ensure they’re free from herbicides or pesticides. For leaves, it’s best to shred them first to expedite decomposition and prevent matting.
• Compost Component: Adding both to your compost pile can accelerate decomposition. Remember to maintain a good balance between green (nitrogen-rich) and brown (carbon-rich) materials.
• Leaf Mold: A fantastic soil conditioner, leaf mold is made by letting leaves decompose over time in a pile or bin on their own. It improves soil structure and water retention.

Safety and Considerations:

• Avoid Thick Layers: Overloading garden beds with thick layers of grass can create a mat that prevents water and air from reaching the soil.
• Disease-Free: Ensure the grass and leaves you’re using are free from diseases to prevent them from spreading in your garden.
• Balance is Key: While they’re a great source of nitrogen and other nutrients, it’s essential to balance their use with other compost materials to ensure a holistic homemade fertilizer mix.
