Complete answer
Seedlings should be fertilized 2-3 weeks after they have emerged and developed their first true leaves. This timeframe allows the seedlings to establish a healthy root system before introducing additional nutrients. It is important to give the roots time to grow and absorb nutrients naturally from the soil before supplementing with fertilizers.
Fertilizing seedlings too early can actually have detrimental effects on their growth. According to a famous quote by gardener and author Louise Riotte, “Fertilizer is like a booster shot; it should be given when the plants show signs of needing and can readily utilize it.” In other words, seedlings should demonstrate their readiness for fertilization through the development of their first true leaves, which are the first leaves that resemble the mature leaves of the plant.
During the initial weeks of growth, seedlings depend on the energy stored in the seed to support their early development. As the seedlings establish their root system, they start drawing nutrients from the soil. This natural progression allows the seedlings to develop a robust and efficient root structure, which in turn supports healthy growth.
Once the seedlings have reached the stage where they have developed their first true leaves, they begin to require additional nutrients beyond what is naturally available in the soil. This is when fertilization becomes beneficial. By providing the right balance of macronutrients (such as nitrogen, phosphorus, and potassium) and micronutrients (such as iron, zinc, and manganese), fertilizers can supplement the nutritional needs of the seedlings, promoting stronger and more vigorous growth.
It is worth noting that not all seedlings require fertilization at the same time. Different plant species have unique growth rates and nutritional requirements. Therefore, it is crucial to refer to specific guidelines or recommendations for fertilizing different types of seedlings to ensure proper timing and adequate nutrient levels.
In conclusion, fertilizing seedlings 2-3 weeks after emergence and the development of their first true leaves allows for the establishment of a healthy root system before introducing additional nutrients. Providing seedlings with the right balance of macronutrients and micronutrients through fertilization supports their growth and overall health, contributing to robust and vigorous plants in the future. Remember the wise words of Louise Riotte, and fertilize when the plants show signs of needing it.
See a video about the subject
In this video, the speaker provides helpful tips on fertilizing seedlings. They suggest waiting for the appearance of true leaves before applying fertilizer and recommend using half-strength organic options like Neptune’s Harvest. Demonstrating how to mix the fertilizer, they emphasize the importance of watering from below and avoiding getting water on the plants. Additionally, the speaker mentions using an oscillating fan to prevent issues like algae growth and fungus gnats. It is noted that only the sweet peas are ready for fertilization, while other seedlings have sprouted and are awaiting growth.
There are alternative points of view
A good rule of thumb is to wait until the seedling grows its second set of true leaves to start fertilizing. The first leaves to emerge from a seedling after germination are cotyledon leaves. True leaves are the actual foliage of the plant. They look and function the same way that all future leaves will.
Seedlings do not need any fertilizer during the early stage of their growth, and applying feed too early can actively harm them. The earliest seedlings can be given fertilizer is when they have their first set of true leaves and hit around two inches tall. The first application should be at the time of potting up the seedlings, and two weeks after potting up, start the liquid fertilizer applications. You should continue the liquid fertilizer applications every week until the seedlings are ready to be transferred to the garden.

All the nutrients that are needed to sustain these cotyledons are contained right inside the seed. But once the second set of "true" leaves appear, you should begin feeding your seedlings with a dilute fertilizer solution. Mix the fertilizer at half the recommended rate and apply it twice a week.

More interesting questions on the issue
When should I first fertilize my seedlings? Seedlings should be fertilized after they are three inches tall and can be fertilized weekly after that until transplanting.
Can you fertilize seedlings too early? The answer is: Seedlings do not need any fertilizer during that early stage of their growth and applying feed too early can actively harm them. The earliest seedlings can be given fertilizer is when they have their first set of true leaves and hit around two inches tall.
Do new seedlings need fertilizer? The response is: Seedlings do not need fertilizer from sowing through the first week after germination because the cotyledons, which are preformed inside the seed, have all the initial nutrition needed to sustain seedling growth. A week after germination, seedlings require a small amount of nutrients, mainly N, P and K.
What fertilizer should I use for seedlings?
The response is: Look for a 1-2-1 N-P-K (nitrogen-phosphorus-potassium) ratio on the fertilizer label. A liquid or water-soluble fertilizer is typically the easiest and quickest way for the seedlings to access nutrients. You’ll also have a choice between organic and synthetic fertilizer, which often comes down to personal preference.
Do you fertilize before seeding? Answer to this: You can fertilize your lawn before or after overseeding. Both tactics work to feed your new grass seed. It’s best to fertilize within 3 days of seeding. This means you can spread your starter fertilizer a few days before you lay down your seed or a few days after. Both are far more beneficial for a healthy lawn than going without fertilizer.
Correspondingly, Do seedlings need fertilizer?
The response is: Timing and frequency depend on its light exposure and the humidity in your home. Fertilization requirements are minimal. Add a bromeliad fertilizer to the dunk solution monthly or so. Temperature: The plants are fine with a range of 50 to 90 degrees Fahrenheit.
Just so, Is it better to fertilize before or after rain?
Response: You can fertilize before it rains, but heavier downpours may wash it away. Therefore, it is better to fertilize before light showers or to wait for drier weather conditions. By doing so, you give the fertilizer enough time to penetrate the soil and benefit your plants. What Happens If It Rains After Fertilizing?
