What is a good substitute for perlite?

What is a cheaper alternative to perlite?

Styrofoam is an economical alternative to perlite, according to the University of Connecticut. Similarly, it is lightweight, but differently, and it compresses over time instead of retaining its airy properties.

Can I use gravel instead of perlite?

Yes! As mentioned above, many gardeners swear by using gravel or sand mixed in with their regular garden soil to improve drainage.

Can I use Styrofoam instead of perlite?

According to many experienced gardeners, Styrofoam can be used instead of perlite. However, it must be the correct kind of Styrofoam, and there are serious environmental considerations to take into account.

How do I make perlite?

Combine 1 part perlite and 1 part peat moss with 1 part compost, pasteurized garden soil -- soil you have baked at 250 F for half an hour -- or purchased bagged soil, usually labeled "Garden Soil," from a nursery to create a potting mix suitable for containers indoors or out.

DIY Perlite Substitute

How do you make perlite with potting mix?

Perlite speeds up germination and improves seedling growth. For seeds, sow on a well-watered mixture of equal parts perlite and Sphagnum Moss Peat. Alternatively, add 1 part perlite to 2 parts ready-mixed potting compost. Perlite is used in potting compost mixes to improves aeration, draining and insulation.

Is perlite necessary for indoor plants?

To ensure that your plants' roots have the oxygen they need for healthy growth, your potting soil should contain plenty of perlite, vermiculite, or sharp sand. This will allow water to drain freely, and ensure that the soil is at least 10 to 20 percent air.

Can I use sand instead of perlite?

Depending on how coarse it is, sand can work as a substitute for perlite. Sand is similar to perlite in that it is pH neutral, sterile, nutrient-free, and facilitates drainage.

Can I use bean bag beans instead of perlite?

Both these materials provide the same function in the soil, but perlite is natural, while plastic beads are synthetic. In that sense, therefore, the fillings of bean bags and potting mix are sometimes the same.

Can I mix Styrofoam with potting soil?

Denise Wolgamott, the recycling coordinator for Rogue Disposal and Recycling, advises that you refrain from mixing Styrofoam in soil for outdoor plants. "Styrofoam does not break down, so we don't advise using it in potting soil," Wolgamott said. Unfortunately, local recycling centers do not accept Styrofoam.

Can I use rice hulls instead of perlite?

Greenhouse growers can substitute rice hulls for perlite in their media without the need for an increase in growth regulators, according to a Purdue University study.

Is perlite really necessary?

Perlite is a highly useful component of gardening for many reasons: It is physically stable and retains its shape, even in heavy or saturated soil. It doesn't decompose, so it's ideal for use in potting mixes for plants that are repotted infrequently (such as succulents and other houseplants).

Can I use peat moss instead of perlite?

Perlite and peat moss are both soil amendments used in horticulture to improve soil moisture retention. Perlite has a stronger structure than peat moss. The strong structure allows perlite to aerate soil, by preventing the soil from densely compacting. Peat moss adds to the density of soil.

Can I substitute vermiculite for perlite?

Perlite and vermiculite are both used to improve moisture retention and aeration in soil. They are used in a similar manner, but they are not interchangeable.

Can I use pumice instead of perlite?

Pumice is heavier than its leading competitor Perlite, which forces it to stay mixed into your soil so it won't float to the top of your containers and blow away. Lastly, pumice will never decompose, so it never needs replacing (unlike Coco Coir and Peat Moss that tends to rot and must be removed.)

Can I use sand instead of vermiculite?

There is no reason to avoid using sand, unless you will be moving the containers frequently. Sand adds a considerable amount of weight but IMO does a better job at aeration than perlite/vermiculite. Perlite also tends to float to the top and grow nasty green algae/mold. I switched over to sand a few years ago.

Is it OK to put Styrofoam in the bottom of a planter?

You can use packing peanuts as long as they're not the type that dissolves in water. Styrofoam peanuts do an excellent job. Make sure they're secured within a bag to keep them stable and in place. It also makes your life easier if you decide to repot the plant.

What do you fill the bottom of a large planter with?

If you have an especially big planter to fill, light, bulky materials are your best bet. Examples include plastic drink containers, milk jugs, crushed soda cans, foam packing materials and plastic or foam take-out containers.

Is vermiculite better than perlite?

Both perlite and vermiculite have neutral pH levels and retain water well. Vermiculite, however, has a reputation for holding a greater amount of water than perlite does. Therefore, perlite would be a better choice for desert climates where succulents grow or for plants like rhododendrons that require less moisture.

Can you mix sand with soil for plants?

Many gardeners compromise by simply sprinkling a little sand on top of their clay soil, but such small amounts do no good; in fact, they actually compact the soil further.

What kind of sand do you mix with potting soil?

Sand adds air space to a potting mix. Builder's sand, or coarse sand, is best. Avoid plaster and fine sands; they create a dense mix. Because it is heavier than other ingredients, sand is a good choice for top-heavy plants that might tip over.

Can I use play sand for plants?

Unfortunately, play sand is not suitable to use for plants owing to potential high saline content and its effect on drainage in the soil. That being said, it is relatively easy to dispose of and there are many other types of sand that can be used to benefit your garden.

What should I put on top of houseplant soil?

Topdressing options can include: river rock, crush slate, replica coverings, moss, crushed glass, hardwood mulch and more. Given the plethora of options, it's best to work with an expert to choose your office plant topdressing wisely.

What is the best soil mixture for houseplants?

A good indoor potting mix should be made up of peat moss and other soilless mediums (coconut/wood fiber, vermiculite, perlite, etc.). While these are vital to your plants' health, it is important to give your plants nutrients, too. Just like us, plants need to eat! This can be done by fertilizing.

Which compost is best for indoor plants?

According to the RHS, for most plants, "A multipurpose compost, houseplant compost or loam-based compost will be suitable for most indoor plants." This is because these types of soil carry plenty of nutrients, holds enough moisture, and then drains the rest properly.
