What plants like coffee grounds and eggshells is a question that one would want to know about because these are two everyday household things you can use to improve your plant’s health.

Plants Like Coffee Grounds and Eggshells

Both coffee grounds and eggshells add various nutrients to the soil, which can be excellent for plants and are inexpensive.

In addition, both offer the minerals that plants require, such as calcium, phosphorus, and nitrogen, suitable for plant growth. The plants you can feed with these nutrients are here in this article.

List of Plants That like Coffee and Eggshells in Their Soil

1. Elephant Ears

  • Moist soil
  • Slow release fertilizer
  • Cut of browning in leaves
Prefers Fresh coffee beans, egg shells and tea bags
Height Three feet
Season to grow Spring


In almost any landscape context, the elephant ear plant creates a strikingly tropical appearance. Therefore, these plants are frequently grown for their enormous, tropical-looking foliage resembling elephant ears. 

Elephant ears have a use in the garden in a variety of ways. These plants are available in a range of hues and sizes.

These big plants can be utilized as ground coverings, edging, or background plants, particularly in areas near ponds, pathways, or patio enclosures. However, they are most frequently used as an accent or focal point, not just that but, even many of them are ideally suited to container gardening.

Giant Elephant Ears Leaves

The plant growth provision is actually simple, even though some of these plants can be planted in full sun, they typically grow best in rich, wet soil and moderate shade.

The tubers can be planted directly outside when the risk of frost or freezing temperatures has passed in your location. Plant the tubers with the blunt end down, two to three inches deep. 

When you are about to cultivate them, remember that the bulbs can also be planted about eight weeks before the last day of frost. You must use healthy, organic potting soil and plant them all at the same depth if you’re growing in pots. 

Before putting elephant ear plants outside, they should be hardened off for about a week, elephant ears require little maintenance once they are established. You should water plants frequently during dry seasons, especially those growing in containers.

Sporadically add a slow-release fertilizer to the soil, while it’s not necessarily necessary, on the other hand, during winter, you should be mindful that outdoors is too harsh to them, and it may even lead them to degenerate. 

Temperatures below freezing harm roots and kill the foliage. Therefore, the plants need to be dug up and kept indoors in areas with chilly, brutal winters, just like the northernmost parts.

After the first frost in your area, trim the leaves back to a few inches, and then carefully dig the plants up. The tubers should be allowed to dry for approximately a day before being stored in peat moss or shavings. 

Next, put them somewhere cool and dark, like a basement or crawlspace. Container plants can be brought indoors or overwintered in a covered porch or basement.

2. Hibiscus 

  • Frequent watering
  • Mulch around the soil
  • Keep pruning once fully bloomed 
Prefers Add coffee grounds 
Height Two to three feet
Season to grow Spring


Perennial hibiscus plants give the landscape a dramatic, tropical feel with their enormous, dinner-plate-sized blossoms. Additionally, hummingbirds and butterflies find them to be very alluring.

It comes in a variety of varieties, for instance, the perennial hibiscus, are ones that may grow up to 12 inches wide and have astonishingly attractive, large, disc-shaped, hollyhock-like flowers, are covered in this growing guide.

Red Hibiscus Flower Blooms

Generally, they can be acquired from nurseries as young plants, and spring planting is the optimum time to plant them. Alternatively, they can be produced from a springtime clipping.

On another note, the seeds should be in the soil indoors at least 11 weeks before the last spring frost date if you want to grow them from seed. Before planting, soak seeds for an hour in hot water. 

Hibiscus plants should be placed in pots with their stems touching the soil’s surface. Cut a branch five to six inches long and peel off the bottom leaves to root a cutting in the spring. Plant the cutting in a pot with a three-to-one sand-to-peat ratio. 

Within a few weeks, roots should start to form. Plant seeds from the bank in the ground, the hibiscus varieties that wither away a year can be placed two to three feet apart. 

Before planting, consider the mature plant’s potential height and width, which is nearly up to 12 feet and 10 feet, respectively. When growing, be careful to give your plants plenty of water.

Hibiscus requires regular watering, especially when it is young and newly established. Water the plant thoroughly and deeply, soaking it. Mulch should be applied all around the plant to help it retain moisture and protect the roots from the cold. 

Moreover, you must make sure to remove wasted flowers before they develop seed heads or, after a flush of blooming is through, trim plants back by one-third to promote rebloom. Every winter, perennial hibiscus will freeze to the ground, so remove old stems. 

3. Tomatoes

  • Full sun
  • Deep soil to one foot for seeds
  • Add manure
Prefers Crushed Egg shells and tea bags
Height Three to four feet
Season to grow Late spring


For a reason, tomatoes are the most popular home garden product and one of acid-loving plants, but they have specific problems. Remember that they are ones that release nitrogen and love calcium-rich soil, which means that eggshells are the perfect ones to be used as fertilizers for them. 

Warm-season crops like tomatoes are delicate, adore the sun, and can’t withstand frost. Therefore, it’s crucial to avoid planting seeds too soon.

Fresh Tomatoes in Plants

Except in zone 10, where tomatoes are a fall crop, the soil is not warm enough to plant tomatoes outdoors until late spring or early summer. 

Depending on the cultivar, tomatoes might take anywhere from 60 to more than 100 days to harvest. Most gardeners use small “starter plants” or transplants rather than seeds because of their comparatively long growing season requirements and later planting time.

Although many gardeners buy their transplants from nurseries or garden centers, you can grow your own from seeds indoors.

Choose a location that gets full sun, which would imply that eight to 10 hours of direct sunlight are ideal in northern areas. Tomatoes will survive and grow better in southern places with light afternoon shade, which can be either natural or imposed, such as row covers. 

Dig the soil to a depth of about one foot, then add compost pile and old manure. Before planting, give it two weeks to break down.

4. Eggplants

  • Prevent toppling
  • Keep adequate space
  • Well drained soil
Prefers Egg shells
Height Two to four feet
Season to grow Spring


In warm climes, you can anticipate picking a dozen or more small-fruited kinds from each Ichiban plant during the summer.

In the yard or the kitchen, more significant types like Black Beauty and White, which produce fruits of more conventional size, are equally stunning. These fruits can be stuffed, grilled, or paired with other vegetables.

Although their tough, leathery leaves are champions at withstanding the heat, eggplants benefit from a thick layer of hay, shredded leaves, or other biodegradable material spread around the base of the plant to keep the soil relatively cold, retain moisture, and suppress weed growth. 

Farming Eggplants in Garden

Gardeners in excellent locations typically find that planting eggplant in big, dark-colored containers works best because the plant truly needs warm soil to thrive. The soil temperature inside black pots maybe 10 degrees higher on a sunny day than below. 

Row covers are a suitable solution in cool climates or even in warm climates to protect plants from cool spells. Allow the bees to access the flowers by opening the ends of the row covers on warm days.

When you wish to fertilize them using natural fertilizers, you can always crush some eggshells after you have rinsed them, and place them in the soil. These shells can be either crushed or even pulverized, which ever is convenient to you.

Eggplants should be spaced 24 to 36 inches apart since they develop into tall, angular plants. Add two inches of compost pile to planting holes to assist the soil in retaining moisture and fertilizer. 

Before applying mulch, set plants at the same depth as they are growing in their containers and give them plenty of water. Fertilize plants frequently to maintain them healthy and vigorous. Growing eggplants successfully relies on having top-notch soil and premium plant food.

5. Marigolds

  • Medium fertile soil
  • Well drained soil
  • Seeds to be planted at a distance
Prefers Fresh coffee grounds
Height three feet
Season to grow Spring


The marigold is the only annual that is too simple to grow. These flowers are the most beautiful annuals, making our summer and fall gardens with a bounty of gold, copper, and brass. The flower’s capacity to bloom all summer vividly contributes to its appeal. Just remember to deadhead for more blooms.

Marigolds produce single or many flower heads that resemble daisies or carnations. Marigolds frequently survive and even thrive in sweltering summers.

Blooming Marigold in Garden

While French marigolds are more tolerant of rainy situations, African and Signet marigolds can withstand drought. However, marigolds are prone to powdery mildew and won’t bloom well if planted in shade and relaxed, moist environments.

Marigolds thrive on moderately fertile, well-drained soil, though they may grow in practically any soil. Dig down approximately six inches to loosen the dirt, then add compost to increase fertility and enhance consistency. 

On the other hand when you have young French or some Signet marigolds, they can surely be planted anytime from spring to mid-summer, but because tall African marigolds take longer to mature and bloom, it is better to produce them straight away in the spring which is right after any risk of frost has passed, and some sun has been shining upon it.

Once the earth is warm in the spring, sow seeds directly into the garden. Although seeds can be started indoors, there isn’t any advantage because they germinate so quickly outside.

African marigolds are an exception, which are best purchased as young plants or grown indoors four to six weeks before your last frost date.

6. Lettuce

  • Moist soil
  • Good drainage
  • Full to partial shade
Prefers Eggshells
Height 12 to 40 inches
Season to grow Spring and fall


In most locations, lettuce is a cool-season crop that produces well in the spring and fall and like a neutral soil pH.

This crop is ideal for novice growers because it can be planted directly from the seed into the soil as soon as the land can be worked. The perfect strategy is to sow a limited number of sources at a time and space out the plants because lettuce develops swiftly.

As long as you give the plants enough water, lettuce is an excellent leafy green since it proliferates, produces for a long time, and is not highly labor-intensive.

Evergreen Lettuce Vegetables

You can always give the soil more organic material by adding some eggshells to it, and the calcium mineral that is in the soil will help and boost the growth.

This vegetable would thrive on raised beds, making it perfect for confined settings. Lettuce is the ideal plant for pots on decks, patios, balconies, and porches. Although it can benefit from afternoon shade when temperatures spike, it is like a site with four to six hours of direct sunlight. 

The ideal soil is loose, well-draining, and moist but not soggy. Add lots of compost to the ground weeks before planting to increase fertility. Cool the earth in August for a fall crop by soaking it and covering it with straw. 

A two-foot row of lettuce can be sown in the ground beneath the bale one week later when it is a few degrees cooler than the rest of the garden.

Rotate the straw bale around the park once every several weeks to complete the process. Plant seeds as usual for a fall harvest as the temperatures decrease in the autumn.

7. Strawberries

  • Adequate watering
  • Sandy well drained soils
  • Full sun
Prefers Coffee grounds and eggshell
Height Six to 12 feet
Season to grow Spring


Because fully matured strawberries have a deep, fragrant flavor unsurpassed by their retail counterparts, the tastiest strawberries you’ll ever eat will come from a garden.

One reason to raise your own is to enjoy the melt-in-your-mouth juiciness of freshly picked strawberries. Strawberries are a healthy addition to any garden because they are one of the earliest springtime fruits to ripen.

Red and Green Strawberries

Understanding the strawberry’s life cycle is necessary for success. Like most hardy perennials, strawberries lose their leaves in the winter and begin to sprout again in April when the acidic soil starts to reheat. 

Wide varieties of strawberries generate multiple runners with new plants at the terminals after bearing fruit meaning this would start as early as February in Florida or June farther north, which shows that it depends upon the region that you are in.

However, when you provide the soil with the right amount of minerals, that is what will give the plant a full on courage to grow well. 

These runners frequently take root close by while continuing to be connected to the mother plant. These strawberries yield more fruit if most runners are removed, limiting the number of daughter plants each plant can generate to three per summer, although some strawberry types produce few or no runners.

Strawberries often take a second rest period in the second half of the summer, worn out from producing fruit and progeny. However, most parent plants and their children perk up and grow anew for a period in the fall when kept weeded and moderately watered. 

Even while it may seem like not much is happening with strawberries in September, the plants are actively creating dormant buds that will bloom the following spring during the fall. 


Contrary to what people believe, everyday foods are a source of nutrition not only for humans but for plants as well.

Just be sure to check the following:

  • Plants prefer eggshells and coffee grounds because not all plants are the same. 
  • Indoor plants shouldn’t be given coffee too much since the beans can produce mildew indoors. 
  • Along with nutrition, exposure to light and soil fertility also matters. 
  • You can always add eggshells in different ways, whether it is by churning it to powder texture, or leaving it crushed with bigger pieces.

So there you have it, plant a garden with the proper nutrition to show off next summer. Happy Growing!
