What Kind of Soil is Best for Spider Plants?

Spider plant proliferates in a light substrate that does not get soggy with a weekly or more frequent watering routine.

Therefore, contemplate these factors before buying or preparing a potting mix for your Spider plant.

1. Drainage-capacity

Like most houseplants, Spider plant prefers well-draining substrate that retains moderate moisture without getting soggy.

Too quick or too slow draining is, either way, harmful to the Spider plant.

You can use perlite, coco peat, and compost to adjust the drainage and retention capacity of the soil.

2. Nutrient-Rich Soil

Spider plants are voracious feeders. They seek heavy nutrient-rich soil to thrive.

Replenish the soil nutrients via once or twice-a-month fertilization during spring and summer.

Other than commercial fertilizers, aim for organic matters like humus, compost, and worm castings that won’t cause fertilizer burn.

Also, inorganic materials like vermiculite supply nutrients, making soil porous and boosting aeration.

Lack of nutrients in the soil can cause wilting and falling leaves and eventually can kill the plant.

3. Soil pH Value

Spider plants prefer slightly acidic soil with a pH ranging from 6 to 6.5 but can tolerate up to 7.0.

The pH level between 6 and 7 ensures low availability of fluoride and keeps Spider plant safe from it.

Excess fluoride in soil for an extended period can develop brown tips in Spider plants.

Thus, add sphagnum peat, coffee leftover, or iron sulfate to make the soil acidic if the pH value exceeds 7.5.

Similarly, if the pH value of the soil is less than 6.0, you can use limestone to compensate.

4. Proper Aeration

Compact soil does not facilitate oxygen flow and discourages healthy bacteria growth.

Moreover, tightly packed, dense soil is a perfect recipe for diseases like fungal growth, root rot, etc.

Thus, provide your Spider plant with light, airy, sandy, loamy soil and poke potting soil with a blunt knife or chopsticks without hurting roots.

You can add pine or orchid barks, pumice and charcoals to boost soil aeration and lower soil compaction.
