Still, some types are trusted over others by gardeners who prefer chemical options. We\u2019ve included one of these below, in addition to our top picks for organic gardening.<\/p>\n
Let\u2019s take a look at the list!<\/p>\n
1. Alaska Fish Emulsion<\/h2>\n
For leafy crops, such as collard greens<\/a><\/strong>, chard<\/a><\/strong>, lettuce, spinach, and endive<\/a><\/strong>, Alaska Fish Emulsion is an excellent product, with a 5-1-1 NPK ratio.<\/p>\n The large percentage of nitrogen is just what they need to produce large, thick leaves that resist pests and disease.<\/p>\n It can also be used on brassicas, cucurbits, and nightshades, but sparingly and only early-on in the growing process.<\/p>\n Onions and other bulb-forming species will enjoy regular applications of fish emulsion, which will aid in producing large, healthy bulbs.<\/p>\n Plant roots can easily absorb fish emulsion, which is great for quick results, but also means that it\u2019ll be depleted rather quickly.<\/p>\n This has its pros and cons, however, because that extra nitrogen won\u2019t linger to cause foliage overgrowth in varieties that don\u2019t need it like it might when using chemical fertilizers.<\/p>\n Alaska Fish Emulsion<\/a><\/strong><\/p>\n Since it comes in liquid form, it can be diluted with water and applied as a foliar spray to plants such as lettuce and spinach \u2013 their thin leaves will absorb available micronutrients through the leaf surfaces.<\/p>\n Find Alaska Fish Emulsion fertilizer is available via Amazon<\/a><\/strong>.<\/p>\n Even though they\u2019re not as widely known as conventional fertilizers, worm castings are a wonderful source of dozens of micronutrients, trace minerals, and healthy microbes.<\/p>\n Their thick, soil-like texture can also improve the substrate in the garden and feed loam-loving varieties of vegetables.<\/p>\n Waste is created by worms as they process organic material in the soil, which can then be collected in the form of castings.<\/p>\n This happens naturally below the soil surface anyway by the slithery inhabitants that live there, but adding more as a top-dressing or raking them in increases its richness.<\/p>\n It\u2019s also suitable for use in container gardens<\/a><\/strong>.<\/p>\n Castings contain an average of 60 different macro- and micronutrients, making them a well-rounded addition for growing almost any crop.<\/p>\n While the NPK ratio is difficult to decipher, the soil can always be tested to be sure that the nutrients your crops need most are available.<\/p>\n Arbico Organics Earthworm Castings<\/a><\/strong><\/p>\n Other fertilizers can be used in conjunction with castings if deficiencies are found.<\/p>\n Buying a packaged product is a perfectly viable option if the price isn\u2019t a hindrance, but home worm farming<\/a><\/strong> is also a great way to go \u2013 and it\u2019s a super fun project for the kiddos, too.<\/p>\n Find bags of worm castings available for purchase in quantities of one-, five-, 10-, and 25-pounds at Arbico Organics<\/a><\/strong>.<\/p>\n Because of its high nitrogen and phosphorus content (6-8-0 NPK), bone meal is great for alliums such as onions<\/a><\/strong> and garlic<\/a><\/strong>, which are long-season, heavy feeders.<\/p>\n It promotes well-established roots and bulbs and gives the scapes a boost to support photosynthesis.<\/p>\n It\u2019s also a good choice for starting fruiting crops such as tomatoes, peppers, and cucurbits as it supports development in the early stages of life.<\/p>\n Note, however, that high-nitrogen fertilizers can lead to foliage overgrowth, so it should be swapped out for a lower nitrogen product later in the life cycle for fruiting plants.<\/p>\n Burpee Bone Meal<\/a><\/strong><\/p>\n Bone meal is made of pulverized bone, usually from byproducts of the meat industry.<\/p>\n A three-pound bag can be purchased from Burpee<\/a><\/strong>.<\/p>\n It\u2019s a good way to put that waste to use while providing many macro- and micronutrients to plants, such as calcium, magnesium, and iron.<\/p>\n Broadcast it over the root zone or rows for alliums early in the season and again at midseason, or mix it with your seed-starting medium for other varieties, according to package instructions.<\/p>\n You can learn more about how to use bone meal here<\/a><\/strong>.<\/p>\n There is a large selection of Dr. Earth products available, including all-purpose vegetable fertilizers and crop-specific types, in both liquids and granules.<\/p>\n No doubt that they\u2019ve probably come up in search results for you before \u2013 this is a very popular, trusted brand.<\/p>\n Whereas most of their fertilizer products can be used on a wide array of crops, Dr. Earth Bulb Food is a granular conditioner formulated especially for tuber and root crops (and flowering bulbs), with a 3-15-2 NPK ratio.<\/p>\n Notice that the phosphorus is available in the largest amount here; this is because it\u2019s the most essential nutrient for healthy root development.<\/p>\n Obviously, this is perfect for vegetables that produce edible roots such as potatoes<\/a><\/strong>, carrots<\/a><\/strong>, beets<\/a><\/strong>, and radishes<\/a><\/strong>, as well as flowering bulbs like tulips and daffodils.<\/p>\n Dr. Earth Bulb Food<\/a><\/strong><\/p>\n This blend is contains feather and fish bone meal, rock phosphate, and alfalfa meal, which not only adds a variety of important nutrients to the soil, but can also improve soil structure as well.<\/p>\n Apply it prior to planting and again at midseason for best results.<\/p>\n Find four-pound packages of Dr. Earth Bulb Food available from Amazon<\/a><\/strong>.<\/p>\n Some garden-variety plants prefer a slightly acidic substrate.<\/p>\n Cucumbers<\/a><\/strong>, radishes, garlic, and carrots are just a few of these, and blueberries<\/a><\/strong> and raspberries<\/a><\/strong> (although these are admittedly fruits, not vegetables) are on that list as well.<\/p>\n Acid-lovers are better served with a fertilizer specifically formulated to increase acidity a bit. If these conditions aren\u2019t met, nutrient absorption is hindered, and the plant will suffer.<\/p>\n Down to Earth (or DTE) Acid Mix is best suited for these species. It contains cottonseed meal, which is produced as a byproduct by the cotton industry, and has an NPK ratio of 4-3-6.<\/p>\n Down to Earth Acid Mix<\/a><\/strong><\/p>\n Applications in the spring and fall will support healthy growth, budding, and blooming, as well as root development for cold tolerance.<\/p>\n It can be broadcast over the soil surface, mixed into the soil medium, or diluted and sprayed according to package instructions.<\/p>\n Arbico Organics carries<\/a><\/strong> one-, five- and 15-pound packages available for purchase.<\/p>\n Ecoscraps Leafy Greens Plant Food is a blend that contains organic materials recycled from food industry waste.<\/p>\n It\u2019s the next best thing to your own compost, with the advantage of a guaranteed ratio of 5-4-5 NPK.<\/p>\n It\u2019s formulated for herbs and leafy greens, so this granular type works best for lettuce, kale, spinach, and other crops that need a foliar boost.<\/p>\n Because it\u2019s relatively well-balanced, however, it can also be useful for other crops that enjoy a bit of extra nitrogen, such as onions, corn<\/a><\/strong>, and brassicas like broccoli<\/a><\/strong> and cabbage<\/a><\/strong>.<\/p>\n Ecoscraps Leafy Greens Plant Food<\/a><\/strong><\/p>\n You can find four-pound packages available via Amazon<\/a><\/strong>.<\/p>\n It\u2019s recommended to broadcast three cups of granules per 50 square feet of ground and rake it in well. Schedule feedings according to package instructions.<\/p>\n Many gardeners have heard of, or tried, Espoma products. It\u2019s another trusted brand that offers a wide range of fertilizers and conditioners.<\/p>\n Espoma Garden-Tone is one of the most commonly used products from their line.<\/p>\n This organic, slow-release formula works well for many crops with its 3-4-4 NPK ratio. It\u2019s also enriched with beneficial microbes to improve soil health.<\/p>\n Cucurbits, asparagus<\/a><\/strong>, herbs, tomatoes, and kale, among others, will all benefit from application.<\/p>\n Espoma Garden-Tone granules can be applied prior to planting at three pounds per 50 square feet to condition the site.<\/p>\n Espoma Garden-Tone<\/a><\/strong><\/p>\n It can also be broadcast between rows of seedlings one to two weeks after planting, or sprinkled in rings around the root zone throughout the season. Be sure to water it in well.<\/p>\n You can find four-pound packages available via Amazon<\/a><\/strong>.<\/p>\n While these are actually three separate products, they work in conjunction and are best used together. They can also be used separately, if you\u2019d prefer.<\/p>\n They support healthy growth, budding, and blooming throughout the life cycle, so even though each has a different ratio of elements, the overall effect of the nutrients contained in the three types works well during various phases of growth.<\/p>\n All three products are available as bottled liquid concentrates, which means they\u2019ll need to be diluted with water for use.<\/p>\n You can find the Nutrient Trio Soil Formula, a multipack of Grow Big, Big Bloom, and Tiger Bloom available via Amazon<\/a><\/strong>.<\/p>\n Nutrient Trio Soil Formula<\/a><\/strong><\/p>\n They should all be applied according to package instructions, and it\u2019s important to take note of when each should be applied \u2013 during initial growth stages, during budding, and during blooming.<\/p>\n Grow Big has a 6-4-4 NPK ratio, meaning it contains a slightly higher level of nitrogen.<\/p>\n This concentrate is designed to support healthy foliage growth and thick, sturdy stems after germination. It should be added to Big Bloom during early phases of growth.<\/p>\n Norwegian kelp and earthworm castings also offer a wide range of macro- and micronutrients essential to healthy development.<\/p>\n This formula is suited for blooming, fruiting varieties of vegetables such as tomatoes, peppers, cucumbers, squash, and others that need a strong structure to support the weight of their fruits later in their life cycle.<\/p>\n Foxfarm Grow Big<\/a><\/strong><\/p>\n Foxfarm Grow Big is available in quart-sized bottles via Amazon<\/a><\/strong>.<\/p>\n Big Bloom also works as a standalone product, but when used in conjunction with Grow Big and Tiger Bloom, it is designed to establish a foundation that supports blooming and healthy foliage.<\/p>\n Use Big Bloom throughout the plant\u2019s life cycle to ensure that a low level of nutrients is consistently available, with a ratio of 1-3-7 NPK.<\/p>\n Ingredients such as bat and bird guano, earthworm castings, Norwegian kelp, rock phosphate, and amino acids ensure that nutrients are available, free for absorption, and well balanced.<\/p>\n This product also improves oil production, so it\u2019s great for growing herbs with a rich flavor.<\/p>\n Foxfarm Big Bloom<\/a><\/strong><\/p>\n Because of low NPK concentration, it can be used on any crop. In conjunction with its counterparts, it works best for fruiting plants and herbs.<\/p>\n You can find Foxfarm Big Bloom available in pint- and quart-sized bottles from Amazon<\/a><\/strong>.<\/p>\n Tiger Bloom is the third step which should be applied during blooming and fruit setting. This concentrate contains 2-8-4 NPK, meaning that it has a higher phosphorus content.<\/p>\n Phosphorus is extremely important for flowering and fruit production, so adding this liquid at the onset of budding will help to support development for better retention, leading to an improved maturity rate.<\/p>\n Tomatoes, peppers, and other fruiting species will enjoy the boost.<\/p>\n As I mentioned, this product replaces Grow Big in the last phase of growth.<\/p>\n Foxfarm Tiger Bloom<\/a><\/strong><\/p>\n It\u2019s important to note, however, that excessive phosphorus can lead to stunting, so always be sure to follow printed instructions and avoid overapplication.<\/p>\n Grab a pint- or quart-sized bottle of Tiger Bloom from Amazon<\/a><\/strong>.<\/p>\n Seaweed extract, such as Sea-K, adds more than 70 enzymes, vitamins, and minerals.<\/p>\n Its blend of 0-0-18 NPK supports stressed plants and encourages healthy, productive blooming.<\/p>\n Potatoes, corn, okra<\/a><\/strong>, and strawberries<\/a><\/strong> (I had to squeeze another fruit in here!) particularly relish applications of this powder, which is best applied as a diluted foliar spray.<\/p>\n It can also be used as a liquid soil conditioner, which helps to support roots and improve water retention.<\/p>\n Other species that will benefit from kelp include blooming plants, such as tomatoes, squash<\/a><\/strong>, peas<\/a><\/strong>, and cucumbers.<\/p>\n Budding and flowering uses a lot of energy, and the high levels of potassium in this product will replenish it.<\/p>\n Sea-K Seaweed and Kelp Extract<\/a><\/strong><\/p>\n At the onset of budding, apply it according to package instructions to increase available nutrients that will be used in the process.<\/p>\n Seven-ounce, two-pound, or 13-pound packages of Sea-K are available for purchase via Amazon<\/a><\/strong>.<\/p>\n Pulverized eggshells are an excellent source of calcium, and they supply smaller amounts of phosphorus and magnesium as well.<\/p>\n It\u2019s important to note that these should be pulverized prior to application if you\u2019re saving your own, as big pieces don\u2019t provide the same benefits as immediately.<\/p>\n All of your nightshades<\/a><\/strong> \u2013 tomatoes, peppers, and eggplants<\/a><\/strong> \u2013 will thank you for these. Especially tomatoes, which need a greater amount of calcium to combat blossom-end rot<\/a><\/strong>.<\/p>\n Broccoli and Swiss chard also enjoy the extra calcium, as do cucurbits and legumes.<\/p>\n Packages of pulverized eggshells from TruBlu can be purchased from Amazon<\/strong><\/a> in one-pound bags.<\/p>\n Crushed shells can be added to potting mix at planting time, broadcast over the root zone, or added to compost at any time.<\/p>\n Learn why eggshells make an excellent amendment and the best ways to use them in our complete guide<\/a><\/strong>.<\/p>\n If you must use a chemical product, one such as Vigoro Tomato and Vegetable is suitable.<\/p>\n Just as it sounds, it\u2019s formulated for use on a variety of crops, although its 12-10-5 NPK ratio works best for species that need strong nitrogen support, such as leafy plants.<\/p>\n This slow-release plant food includes additional calcium to help prevent blossom end-rot, and it can be applied throughout the season as needed, according to package instructions.<\/p>\n Vigoro Tomato and Vegetable<\/a><\/strong><\/p>\n It\u2019s also suitable for use on fruiting crops like tomatoes, so it can be broadcast over the whole garden bed for universal coverage.<\/p>\n Find three-and-a-half-pound packages available at Home Depot<\/a><\/strong>.<\/p>\n Hopefully, you found some useful tips and some direction among the items that were mentioned.<\/p>\n Fertilizing the garden doesn\u2019t need to be a confusing step.<\/p>\n Trial and error works for some, but starting with a strong foundation reduces the amount of loss and extra effort that is expended in correcting mistakes.<\/p>\n If you still have questions, please leave them in the comments below \u2013 we\u2019re always here to help!<\/p>\n What are you growing this year?
