What Kind of Pebbles Should You Use for Indoor Plants?

Answer

Container gardening interiorscape design makes use of similar hardscape characteristics, but on a much smaller scale than in other landscaping design installations. These landscaping design installations often use enormous ornamental rocks in garden beds and border plants. The precise purpose of the pebbles you use for your indoor plants should guide your decision on the kind of pebbles to utilise. It doesn’t matter if you want to use pebbles as vase fillers for fresh-cut flowers to complement your home décor, accents for dish gardens, mulches for conserving moisture, or components in potting mixes; these minihardscaping components can add aesthetic or utilitarian value, or both, to your houseplants.

Tip

You may use a wide range of pebbles and rocks for indoor plants, such as ornamental pebbles, clay pebbles, pea gravel, polished pebbles, and river rocks. The kind of pebbles and rocks you choose will depend on the individual application.

Choosing Pebbles for Top-Dressing

The visual attractiveness of your houseplants may be improved by adding some top-dressing in the form of a single stone or a collection of colourful pebbles by putting them in the containers in which they are housed. The colour, shape, and texture of the rock pebbles you select will ultimately depend on your personal preference. However, taking into consideration certain variables, such as scale and colour (for the plants as well as their containers), as well as the type or theme of your do-it-yourself creation (for example, dish gardens, fairy gardens, and terrariums), can help you fine-tune your minihardscape choices.

White pebbles may be used to create a contrast with a container that is black or cobalt blue, or they can be used to replicate the colour that is present in a pattern of white dots or white streaks on the leaf of your plant. Use smaller river rocks to create the appearance of a dry stream bed in bonsai dish gardens, and use bigger ornamental rocks of varying sizes and shapes to create a focal point in terrariums. This will give the impression that there is flowing water in the garden. Create a winding path around your fairy garden using tiny pebbles or pea gravel as the edging. Stones that are sold in commercial packaging, such as Mosser Lee river pebbles, are manufactured with the express purpose of being utilised as polished pebbles in terrariums, dish gardens, and fairy gardens.

Stones that are sold in commercial packaging, such as Midwest Hearth Natural Decorative Polished Pebbles, are manufactured with the express purpose of being used in the creation of terrariums, dish gardens, and fairy gardens. Each stone has a diameter of about a third of an inch and is finished with a coating of paraffin wax for a shiny appearance. The ornamental stones do not include any fillers, dyes, or oils that can be harmful to your plant in the long run. There are a total of four distinct hues available, and they are as follows: Polished White, Polished Mixed, Polished Jade, and Polished Black. The stones are sold on Amazon in quantities of 2 pounds, 5 pounds, and 10 pounds per bag, and they are available in a wide range of shapes and colour combinations. A 10-pound bag will cover about 1 square foot to a depth of 1 inch, according to a general rule of thumb. If, on the other hand, you want to use the stones as filler for a vase or terrarium, a 10-pound bag will provide you 144 cubic inches of volume to work with.

Choosing Pebbles as Mulch

It’s possible that adding stones to create a firm mulch layer on top of the soil mix for your indoor plants is also considered top-dressing for those plants. Because the pebbles reduce the rate of evaporation, you won’t have to water your plants as often, even if they are really thirsty and need a lot of water. The size of your pebbles may either enhance or detract from the appearance of your container plants. For instance, putting huge boulders as mulch in a tiny pot results in an uneven appearance, but using little pebbles as mulch works as well in either a large or a small pot.

Amazon has individual 5-pound packages of Mosser Lee’s marble-like gravel nuggets for sale. These gravel nuggets are inspired by marble. The soil cover was created with indoor plants and other houseplants in mind; however, it may also be used in terrariums and dish gardens. Since the gravel nuggets are quite small and have a smooth appearance, they are an excellent choice for use in both decorative and practical applications. In addition to preventing the spread of disease and preserving the integrity of the soil, covering a group of houseplants with a layer of gravel gives them a more streamlined appearance. Having said all of that, the asking price for this product is $2.39 per pound, which is far more than what you would generally find at a big-box home improvement shop.

The form that pebbles take is another another factor to take into account. When you water your plants, for instance, rocks that are jagged or have an irregular form may have a greater propensity to cause splashback, in contrast to pebbles that are smooth and rounded. Only use tiny stones as accent pieces when you are mulching succulent plants. These drought-tolerant succulents are sensitive to fungal root rot diseases that are favoured by damp soils. A firm mulch layer may retain in too much water for these succulents, which are prone to these diseases.

Incorporating Pebbles in Potting Mixes

When used in potting mixes, tiny pebbles enhance the porosity of the mix, which means that there are more gaps between the soil or soilless mix. This results in improved drainage. Others merely utilise mixes that are sold commercially in packages, in contrast to the many expert growers who have their very own secret recipe for a mixture of specific components that they employ in their growth medium. You can make your own potting mix at home by including small pebbles or even aquarium gravel, or you can follow the lead of professional growers and purchase a soil mix that is already prepared for planting.

Clay pebbles are an important ingredient in a variety of potting mixtures used for bonsai. For you go to the store to buy clay pebbles, you can also find them packed under the name “hydroton.” Hydroton is an enlarged clay aggregate that is often used when potting or repotting orchids. The enlarged clay pebbles have teeny tiny air pockets inside them, which act as reservoirs for oxygen and moisture. In addition to their utility in controlling humidity, they are very effective as a fungus gnat and other insect repellent.

Amazon has inventory of Mother Earth’s Hydroton Original Expanded Clay Pebbles in three different bag sizes: 10 litres, 25 litres, and 50 litres. Before using the pebbles, the company recommends giving them a good washing in order to get rid of any dust that may have accumulated on them. It is recommended that this task be carried out in the open air since the accumulation of sediments might cause plumbing issues in the future. The porous clay pebbles are from Germany and vary in size from 8 millimetres to 16 millimetres (about one third of an inch to slightly more than half an inch). In addition to this, if you disinfect them in between plantings, you may use them again and again. On Amazon, you may purchase a bag of expanded clay pebbles made by Mother Earth.

If you’ve ever used potting soil and seen white bits that seem like popcorn, be assured that they are neither rocks or stones. There’s a good chance that it’s perlite, a mineral that may be found in volcanic glass and expands when it’s heated. Pebbles may be better for drainage, but perlite is much easier to work with since it is so much lighter. Because of its lower density compared to pebbles, perlite may be a better choice than pebbles for enhancing drainage in an indoor plant that is growing in a big container. This is due to the fact that perlite is lighter.

Always use containers that include drainage holes to prevent root rot, which occurs when plant roots remain in damp soil for an extended period of time. The Colorado State University Extension recommends a technique that you may use pebbles in a double-potting hack to get past this problem. The hack uses pebbles as a means to get over the absence of drainage holes in many stunningly ornamental containers. Plant your houseplant in a plastic pot that can be placed within the ornamental container. This is preferable than planting it straight into the container that is just there for decoration and does not have drainage holes. A layer of pebbles should be placed at the bottom of the ornamental container, and then the pot that has drainage holes should be placed on top of the stones. Your potted plant’s excess water will flow into the layer of stones rather than completely soaking the potting mix as it drains out of the container.

Using Pebbles to Increase Humidity

A great number of houseplants come originally from tropical areas, where the levels of humidity are much higher than the levels in your home. Consider using pebbles as a technique to enhance the humidity around your potted plants as an alternative to using a humidifier to add moisture to the air. Pebbles absorb and release moisture into the air. Simply set the container plants in saucers filled with water and pebbles or pea gravel, making sure that the water level is just below the top of the stones so that your pots are not resting in the water. You may also use pea gravel. According to the University of Georgia Extension, some gardeners add charcoal chips to the pebbles in their water gardens in order to prevent the water from smelling foul.

Some plant species, collectively referred to as “air plants” (genus Tillandsia), do not need soil for growth since they can get all of the moisture they require from the surrounding atmosphere. These pebble- and water-filled trays are beneficial to air plants when the environment is dry, especially during the winter months when the air is devoid of humidity as a result of using a heating system in the house. These plants are often fastened to seashells or pieces of wood, both of which may be placed atop an inverted container that is supported by a pebble humidity tray.

Pebble humidity trays may be obtained in a three-pack via the online marketplace that is provided by Walmart. The three-part tray set, which ranges in length from 8 to 11 to 13 inches, is designed to absorb surplus water, which, in turn, raises the relative humidity surrounding the air plants. The ornamental pebbles in an off-white colour are included, and you may place the weather-resistant plastic trays either indoors or outside. If growing air plants isn’t your thing, you may maintain orchids or bonsai trees with the humidity trays instead. Your plants that thrive in high levels of humidity will benefit greatly from the additional moisture that may be provided by this inexpensive accessory, which costs less than $20 for the pair.
