There are several strategies you can implement to help your plants grow faster, such as selecting the right fertilizer. Fast-growing plants allow you to harvest your crops earlier or even receive gifts like a bouquet of flowers. Once you know how to care for your plants and which species to grow, you will be on the right path to a quicker harvest.
Steps
Fertilize the plants

Test the soil In order to choose the correct fertilizer, you need to understand the composition of your soil. You can buy a soil testing kit from large department stores or garden centers. The results will tell you what nutrients need to be added to achieve the proper balance for optimal plant growth.
- You can also send a soil sample to an agricultural lab for more specific results.

Choose between organic or inorganic fertilizers. Decide whether to use organic or inorganic fertilizers. If you opt for inorganic fertilizers, find a blend that can provide the best nutritional balance that your soil needs. Organic fertilizers are harder to assess since each type varies in the nutrients it provides. Organic fertilizers must break down into inorganic substances in the soil for plants to absorb them, meaning they will take longer to show results.
- Inorganic fertilizers provide immediate nutrients, promoting rapid plant growth. Organic fertilizers release nutrients slowly into the soil, but in the long run, they create a healthier soil environment. If your goal is a quick harvest and accelerated growth, inorganic fertilizers are the better option. However, if you want a sustainable garden or bed, organic fertilizers are more beneficial.

Decide between granular or liquid fertilizers. Granular fertilizers come in small pellets. Like organic fertilizers, granular fertilizers are best for long-term projects like garden beds. Granular fertilizers are coated with a resin shell, allowing nutrients to be gradually released into the soil. Liquid fertilizers work much faster, but need to be applied more often, typically every few weeks. Liquid fertilizers are also more expensive.
- Choose your fertilizer based on the timeline of your planting project. If you want long-term growth, granular fertilizer is ideal because it will improve the soil’s fertility over time. If you have plants that need immediate care, liquid fertilizer is more appropriate.
- If you choose liquid fertilizer, be sure to follow the instructions carefully. Over-fertilizing can harm your plants, possibly killing them from an overdose.

Check the nutrient components of your fertilizer. Plants need 16 essential nutrients for proper growth. The primary nutrients are nitrogen, phosphorus, and potassium, known as macronutrients. Secondary nutrients include sulfur, calcium, and magnesium. Lastly, plants also require trace elements like boron, cobalt, copper, iron, manganese, molybdenum, and zinc.
- Plants will not grow without the three essential macronutrients.
- Some fertilizers are enriched with additional nutrients. If you are growing a specific plant, such as a particular flower, these fertilizers can aid in growth. However, if you are growing multiple types of plants at once, it’s best to use a fertilizer that doesn’t contain extra added nutrients.

Determine the nutrient ratio in the fertilizer bag. Different fertilizers have different nutrient ratios. For example, a 6-12-6 fertilizer contains 6% nitrogen, 12% phosphorus, and 6% potassium. Choose the best mix for your soil based on the soil test results.
- If your soil is already balanced, select a 10-10-10 fertilizer. This type of fertilizer often has a high nitrogen content, as nitrogen is the nutrient most commonly deficient in soil. It also frequently contains phosphorus and magnesium.

Apply fertilizer to the plants. It’s best to evenly spread the fertilizer into the soil. If using granular fertilizer, you can use a fertilizer spreader to distribute it evenly.
- If you’re applying fertilizer to outdoor plants, remember to clean up any fertilizer that spills onto pathways to prevent it from washing into drainage areas.

Regularly fertilize your plants. Plants absorb nutrients quickly. To ensure your plants are getting a steady supply of nutrients, you need to fertilize based on their specific needs, taking into account the type of plant and fertilizer. Be sure to follow the instructions on the packaging for the correct dosage.
- If you purchase a pre-planted pot, check the tag attached to the plant to identify the type of soil it is planted in. This will guide you on how often to fertilize the plant.
Select the right type of plants.

Choose the type of plant you wish to grow. Different plant varieties grow at different rates. Be sure to research the various types of plants you want to grow. For example, the Glacier tomato variety only takes 50 days to mature, compared to the typical 70-90 days of other tomato varieties.

Consider growing leafy greens. Certain leafy vegetables grow quickly. Microgreens take just 14 days to grow. Arugula lettuce requires 21 days, while regular lettuce takes 26 days. Many leafy vegetables grow rapidly, especially those used in salads.

Choose the right root vegetables. If you want to grow root vegetables, opt for fast-growing varieties such as beans, beets, broccoli, spring onions, radishes, squash, cucumbers, okra, and peas.

Choose short-blooming flowers. Short-blooming flowers are great for gifting or adding beauty to your garden. Chrysanthemums, dragonfly chrysanthemums, and yellow chrysanthemums grow quickly and are visually appealing. Other excellent flower options to consider are sunflowers, sweet peas, and diamond flowers.
Support plant growth

Start seedlings indoors. If you plan to grow plants outdoors but must wait until spring, start your seeds indoors. Seedlings will take about 4 to 12 weeks to germinate. By starting them indoors and later transplanting them outdoors, you can get a 4-6 week head start compared to direct sowing in the garden.
- Choose small, deep pots (about 5-10 cm) with drainage holes for planting.
- Avoid using fertilizers. Instead, use a mix of peat moss and vermiculite in the pots.
- Allow the plants to spend a few hours outside each day. Do this for at least two weeks before moving them to the garden, helping them adapt to direct sunlight.
- Common plants that transplant well include tomatoes, bell peppers, eggplants, and cucumbers. However, some plants, such as zucchini, beans, beets, corn, spinach, turnips, and peas, do not transplant well.

Talk to your plants. Studies suggest that plants respond positively to being sung to. When fertilizing your plants, try talking or singing to them. You can even record your voice and play it for your plants when you're not around. This may encourage faster growth.

Provide light for your plants. Use grow lights if you're growing indoors. The best type of grow light is a high-intensity discharge (HID) lamp. HID lights come in two forms: metal halide (MH) and high-pressure sodium (HPS). MH bulbs emit the brightest light, particularly in the blue spectrum, which helps promote leaf growth. HPS bulbs are more durable and emit red/orange light, encouraging flowering.

Use coffee grounds. Coffee grounds can help plants grow faster due to the caffeine content found in coffee. They are also rich in nitrogen, a vital nutrient for plants. Studies have shown that caffeine helps accelerate plant growth.
