Commonly available fertilizer analysis that are great for tomato seedlings include 8-32-16 and 12-24-12. Mix the fertilizer with water according to package directions. If fertilizer is applied too frequently, or too much product is used at one time, your tomato plants may be damaged.

Coffee grounds are slightly acidic, so they can lower the pH level of the soil over time. This can be beneficial for acid-loving plants like tomatoes or blueberries, but should be monitored to prevent excessive acidity.

In a compost pile, coffee grounds decompose and break down, mingling with other organic matter like vegetable scraps, leaves, and grass clippings. This process creates a nutrient-rich compost that is much safer and more beneficial for tomato plants.

Feeding. Feed cucumber plants in containers every 10–14 days with a general liquid fertiliser. Once they start flowering, change to a weekly tomato feed, to encourage flowering and fruiting.

Tomatoes, squash, peppers, cucumbers, and other vegetables (and herbs!) will thrive when they're fed every 7 to 14 days with Miracle-Gro® Water Soluble Plant Food for Vegetables & Herbs.

10-10-10 is called an all-purpose fertilizer because it can be used on almost any type of outdoor plant, including vegetables, shrubs, trees, flowers, lawns, and houseplants. Generally, it can be applied to any plant that doesn't need one of the three macronutrients in higher amounts.

Liquid Fertilizers

Some types of fertilizers, such as fish emulsions, can be mixed with water, sprayed onto the leaves, and added during regular watering. A liquid or water-soluble fertilizer is a great option for container tomatoes. Liquid fertilizers should be diluted and are usually applied more often.
