Low humidity may cause brown or scorched leaf tips. Set pots on the pebbles, just above water level. Misting foliage has not proven useful in raising humidity as water droplets evaporate rapidly. Root Environment Root health is vital. The plant's container and the growing mix affect the root system and therefore, overall health.
Roots serve to anchor the plant in the container and to absorb water and nutrients.
A plant's root system must have oxygen in order to function properly. Soil Mix A proper soil mix is critical for good root health. A desirable mix will not break down or degrade over time, and include a mix of particle sizes to provide space for good drainage and aeration. If the soil is compacted or saturated with water, oxygen in the soil is reduced and roots suffer. Soil should be moistened 24 hours prior to heating.
