How to fertilize Blue Lettuce
Most potting soils come with ample nutrients which plants use to produce new growth.

Blue Lettuce doesn’t require additional humidity. Plants absorb most water through their root system rather than their leaves, so the best way to provide humidity for your plants is through watering the soil.
Blue Lettuce does best in well-draining soil. A good soil will contain lots of organic matter such as coco coir as well as perlite or vermiculite to help with drainage. Adding a handful of perlite to regular store-bought potting soil should do the trick!
Blue Lettuce is a fast growing plant and may deplete the nutrients in its soil over time. Replenish them with a gentle organic fertilizer or compost every 1-2 months depending on your location and season. Fertilize more often during the growing season and in warmer and brighter climates.
