The amount of liquid fertilizer per plant depends on the type of fertilizer (houseplant vs. general purpose), the size of the plant, and the specific instructions on the fertilizer label.
Here's a breakdown:
- Houseplant Liquid Fertilizers: These are typically more concentrated and require significant dilution. A general guideline is to use 10 to 20 drops of the liquid fertilizer per 1 quart of water for each plant.
- All-Purpose Liquid Fertilizers (e.g., for vegetables): These are usually less concentrated than houseplant formulas. A common dilution rate is 1 to 2 tablespoons per 1 gallon of water for multiple plants.
Important Considerations:
- Follow Label Instructions: Always read and follow the specific instructions on the liquid fertilizer label. These instructions are tailored to the concentration of the product and the type of plants it's designed for. The label might specify different amounts based on the plant's age or growth stage.
- Plant Size and Type: Larger plants generally require more diluted fertilizer solution than smaller plants. Also, different plant types have different nutrient needs. Research the specific needs of your plants.
- Frequency of Application: The frequency of fertilization depends on the plant type, the fertilizer used, and the time of year (growing season vs. dormant season). Typically, liquid fertilizers are applied every 2-4 weeks during the growing season. Again, the product label provides the best guidance.
- Watering Thoroughly: When applying liquid fertilizer, water the soil thoroughly so the fertilizer solution reaches all the roots.
- Avoid Over-Fertilizing: Over-fertilizing can damage or even kill plants. Signs of over-fertilization include yellowing leaves, stunted growth, and a build-up of salts on the soil surface. If you see these signs, flush the soil with plenty of water to remove excess fertilizer.
Example:
Let's say you have a bottle of liquid fertilizer designed for houseplants. The label instructs you to use 15 drops per quart of water. You have three small houseplants. You would mix 15 drops of fertilizer with 1 quart of water. Then, you would use this solution to water the three plants, ensuring the soil is moistened but not saturated.
In summary, the exact amount of liquid fertilizer per plant varies, but starting with the dilution rates mentioned above and always adhering to the fertilizer label instructions is key to providing your plants with the nutrients they need without over-fertilizing.
