Growing Cannabis in Louisiana

Cannabis, a plant historically cultivated for various purposes ranging from industrial hemp to recreational and medicinal use, has seen an upsurge in legality and acceptance in many U.S. states. Louisiana, renowned for its unique cultural heritage and rich agricultural history, is no exception. This article provides an in-depth examination of the cultivation of cannabis in the state of Louisiana, considering its legal, climatic, and agricultural aspects.

Legal Overview

Before engaging in cannabis cultivation in Louisiana, it’s essential to familiarize oneself with the legal landscape.

Medical Cannabis

Medical cannabis was legalized in Louisiana in 2015, with the Alison Neustrom Act. This act provided patients with a prescription-based access to non-smokable forms of marijuana. However, cultivation for personal use, even by medical patients, remains illegal. Licensed growers work in conjunction with the Louisiana State University and Southern University, the two institutes permitted to cultivate medical cannabis under the state’s guidance.

Recreational Cannabis

As of the last update in 2021, recreational cannabis remains illegal in Louisiana. Those considering cultivating cannabis for personal or commercial use must adhere strictly to state regulations, as unauthorized cultivation can lead to significant legal repercussions, including heavy fines and incarceration.

Climatic Considerations

Louisiana’s climate poses unique challenges and benefits to cannabis cultivation.

Humidity and Rainfall

Louisiana, characterized by its subtropical climate, experiences high humidity levels and significant rainfall. While cannabis plants require moisture, excessive humidity can result in mold and mildew, damaging the crop. Preventative measures, such as the use of dehumidifiers in indoor setups or ensuring proper spacing and aeration in outdoor crops, can mitigate these risks.


The state experiences hot summers and mild winters. These warm temperatures can be ideal for cannabis growth, especially during the vegetative phase. However, growers must be cautious about potential heat stress during particularly hot spells. Shade cloths for outdoor grows and temperature regulation systems for indoor grows can help maintain optimal conditions.

Seasonal Variations

Due to Louisiana’s relatively mild winter, the cannabis growing season can be extended compared to regions with colder climates. However, growers must still pay attention to the daylight cycle, as cannabis plants typically require longer dark periods to flower.

Soil and Land Preparation

Louisiana’s diverse soil types can cater to various agricultural practices, but some amendments may be necessary for optimal cannabis cultivation.

Soil Types

Louisiana’s alluvial soils, found mainly in its river deltas and flood plains, are rich in nutrients. However, they can be heavy and not drain well, making them less than ideal for cannabis, which prefers well-draining soils. Sandy loams or soils with good organic content are preferable. Amending heavier soils with perlite, vermiculite, or organic matter can enhance drainage.

PH Level

Cannabis plants thrive in slightly acidic soils with a pH level of 6.0-7.0. It’s vital to regularly test the soil’s pH and make necessary adjustments using lime (to raise pH) or sulfur (to lower pH).

Pest and Disease Management

Louisiana’s warm and humid climate can be a breeding ground for various pests and diseases.

Common Pests

Some of the primary cannabis pests in Louisiana include spider mites, aphids, and whiteflies. Organic insecticides, neem oil, and introducing beneficial insects like ladybugs can help combat these pests.


As mentioned, the humidity can lead to mold and mildew. Regular inspection of plants, proper spacing, and moisture management are crucial to preventing these diseases. Fungicides, preferably organic, can also be used as a preventive measure or treatment.

Harvesting and Curing

Upon reaching maturity, proper harvesting and curing methods are essential to maximize the quality and potency of Louisiana-grown cannabis.

Harvest Timing

Trichomes, the tiny resin-filled glands on the cannabis buds, give an indication of the right harvesting time. They transition from clear to milky white and eventually amber. For the best balance of THC and CBD, harvesting when most trichomes are milky white with some amber is ideal.

Curing Process

After harvesting, buds should be trimmed and hung upside down in a dark, humidity-controlled environment for 7-14 days. Once dried, they should be placed in airtight jars and stored in a cool, dark place. For the first two weeks, jars should be opened daily to let fresh air in and prevent mold growth.


While the legal challenges around cannabis cultivation in Louisiana are restrictive, the state’s climate and agricultural history make it a viable region for cannabis cultivation. With attention to detail and adherence to best practices, Louisiana can yield high-quality cannabis, whether for medicinal or, if laws change in the future, recreational use. Always remember to consult the latest state regulations before embarking on any cultivation endeavor.
