Why do we need to quarantine new succulent plants?


For succulent enthusiasts and plant parents, nothing beats the excitement of bringing home a new chubby, vibrant succulent. It's a delightful experience, full of joy and anticipation. Each new plant is not just an addition to your collection but another green baby that you can’t wait to nurture and see it flourish under your care, bringing its unique beauty and personality into your space. The thrill of introducing this new life into your home is a special part of the plant-owning journey. 

However, it's important to resist the urge to immediately place your new plant amongst its leafy companions in your indoor garden. No matter how eager you are to see how your new plant complements the others, taking a pause and properly quarantining for the newcomer is crucial. This step is essential for protecting your entire plant family from potential harm and ensuring that each member—including your exciting new addition—continues to thrive and bring beauty into your home for years to come.

What Does Quarantine Mean In Plant Care?

After the Covid19 pandemic, we have become familiar with the term “quarantine”, but what does it actually mean? The word "quarantine" comes from the Italian word "quaranta giorni," which means "forty days." The term originated in the 14th century during the time of the Black Death, when ships arriving in Venice from infected ports were required to sit at anchor for forty days before landing. This practice was implemented as a measure to prevent the spread of the plague by ensuring that no one on board was sick.

Over time, the concept of quarantine has evolved and is now widely used in various contexts, including public health, agriculture, and animal and plant care. It generally refers to a period of isolation imposed on a person, animal, or object that may have been exposed to a contagious disease or pest. In horticulture, quarantining new plants involves keeping them separate from other plants for a certain amount of time to ensure they are not carrying any pests or diseases that could be transmitted to other plants. While it doesn't necessarily last forty days as it did historically, the principle remains the same: it's a precautionary measure designed to protect against potential threats.

Why Do We Need To Quarantine New Succulents?

One of the primary reasons for quarantining new succulents is that they often come from plant nurseries or supermarkets, where they may have been exposed to pests and diseases. These commercial environments, while great for offering a wide variety of plants, can also be breeding grounds for infestations due to the close proximity of so many plants. Common pests like mealybugs, spider mites, and scale insects can easily hop from one plant to another, and once you bring a new plant home, those pests could spread to your other succulents.

New succulents often come from plant nurseries or supermarkets, where they may have been exposed to pests and diseases.

Quarantine acts as a buffer zone to detect any pests that might be lurking on your new succulent. These pests, which can range from tiny aphids to nearly invisible spider mites, are often adept at hiding within the foliage or soil and can multiply rapidly if not caught early. By keeping your new plant separate, you have the opportunity to observe it for any signs of infestation and address them without risking the spread to other plants.

Moreover, the soil in which these plants are potted may harbor pathogens or fungal spores that could lead to diseases such as root rot. These issues might not be immediately visible at the time of purchase; symptoms can take days or even weeks to appear. Quarantine allows you to monitor the health of your new succulent closely, watching for symptoms like leaf spots, wilting, or mold growth that could indicate a problem requiring treatment.

Certain succulent diseases or pest infestations may have an incubation period,during which symptoms are not immediately visible. Quarantine allows for extended observation, helping plant parents detect any latent issues that might emerge over time. Early identification enables timely intervention, reducing the risk of widespread problems within the collection.

Moreover, transportation and changes in environmental conditions during transit can be stressful for succulents. Quarantine allows the plants to acclimatize gradually to their new surroundings. This adjustment period is essential for succulents to recover from potential shipping stress, adapt to different light and temperature conditions, and develop resilience before being placed in shared spaces with other plants. Additionally, not all succulents have the same care requirements. Some may thrive in bright, indirect light, while others prefer more shade. Quarantine provides an opportunity to assess the compatibility of new succulents with the existing collection. This step ensures that plants with similar environmental preferences are grouped, optimizing overall care and promoting the well-being of each species.

How To Quarantine Your New Succulents

Quarantining a new succulent is a straightforward process that involves isolating the plant to monitor its health and ensure it's free of pests and diseases before introducing it to your existing collection.

Establishing a quarantine area

    When welcoming a new succulent into your plant collection, setting up a dedicated quarantine area is the most important thing. This separation aims to shield your existing plants from potential pests, diseases, or other issues that might accompany the newcomer. The quarantine area acts as a protective barrier, offering a controlled environment for close observation and preventive measures. 

    The first consideration in establishing a quarantine area is the physical location. Select a space that is distinct and separate from your established plant collection. This isolation space could take various forms, such as a different room, a specific corner of a room, or even a separate table. The key is to create a clear and defined boundary that prevents direct contact between the new succulent and your existing plants. Don’t forget to clean the area thoroughly before introducing your new plant. Disinfect surfaces and consider using a fresh tray or saucer under the pot to catch any excess water.

    Ensure that the chosen quarantine area provides suitable environmental conditions for the succulent. This includes factors such as lighting, temperature, and humidity. While the quarantine period is typically relatively short, providing conditions conducive to the succulent's well-being is essential for accurate observation and assessment.

    Consider using physical barriers to enhance the isolation of the quarantine area. If the designated space is within a room, place the new succulent on a separate table or shelf. For larger collections, a different room with a closed door can serve as an effective barrier. The objective is to create a clear and defined separation to prevent any potential transfer of pests or diseases.

    If you do not have a separate room for your new succulents, and if your room is small in size, consider transparent barriers or shelves to facilitate visual checks without direct physical contact. You can put your new plants into a plastic bag, ensuring they have enough air circulation

    Ensure that the quarantine area allows for easy visual accessibility. This is crucial for regular inspections and monitoring of the new succulent.

    Monitor Your New Succulents For Signs Of Pests And Disease

    Frequently inspect the new succulent for any signs of pests, diseases, or changes in its overall appearance. Pay close attention to the upper and lower surfaces of the leaves, stems, and the soil around the roots. Look for pests like aphids, mealybugs, spider mites, and any visible signs of fungal or bacterial infections. You should educate yourself about common succulent pests and diseases, so you can recognize symptoms during your inspections. This knowledge will empower you to take swift and targeted action if any issues arise. You should also regularly inspect the topsoil of established plants for any unusual activity such as fungus gnats or mold growth.

    If you identify pests during your inspections, promptly address the issue with appropriate measures. This may include applying neem oil, insecticidal soap, or other organic pest control solutions. Regularly check for the effectiveness of your chosen treatment and adjust as necessary.

    Maintain A Consistent Care Routine 

    Maintaining a consistent care routine during the quarantine period is essential for the well-being of your new succulent. This stability in care helps the plant adjust to its new environment and recover from any stress experienced during transit. A steady routine includes providing the right balance of light, water, and temperature, which are critical factors for a succulent's health.

    • Light: Ensure your quarantined succulent receives adequate light, which typically means placing it in a spot with bright, indirect sunlight. If natural light is insufficient, consider using grow lights to mimic its preferred conditions.
    • Watering: Water your new succulent according to its specific needs, which usually involves allowing the soil to dry out between waterings. Overwatering can lead to root rot, especially in a stressed plant, so it's important to monitor soil moisture closely.
    • Temperature and Humidity: Keep the quarantine area at a temperature range that's comfortable for your succulent—generally between 65°F and 85°F and in a low-humidity condition (humidity level of below 50%).  Avoid placing it near drafts or heat sources that could cause sudden temperature fluctuations.
    • Repotting: Repotting immediately after bringing a new succulent home is not always required. However, if the plant is root-bound, showing signs of stress from inadequate soil, or if the soil is contaminated, repotting into fresh, well-draining soil can be beneficial.
    • Pruning: If you notice any damaged or diseased parts of the plant during your initial inspection, it's best to prune these areas to maintain plant health. Use clean, sterilized pruning tools.

    Isolation Practices

    Establish strict isolation practices to minimize the risk of contamination. Avoid using the same tools, watering cans, or gloves for both the new succulent and your established plants. If possible, change clothing or wash your hands thoroughly before interacting with the quarantined plant. These measures help maintain a clean and controlled environment, reducing the likelihood of cross-contamination.

    Avoid using the same tools, watering cans, or gloves for both the new succulent and your established plants.

    It is important to regularly clean and sanitize your gardening tools, ensuring that each tool set is free from residues that could harbor pests or diseases. Make it a routine of your gardening practices, and you can create multiple layers of defense that protect the health and vitality of every plant under your care, allowing them to flourish.

    Don’t forget that soil can also be a breeding ground for pests and diseases that threaten the well-being of your plants. Many pathogens and insects thrive in soil, lying in wait for an opportunity to infest your succulents. Therefore, it's crucial to manage soil with care to prevent cross-contamination that could lead to an outbreak.

    Isolation Time

    Experts generally recommend isolating new plants for two to four weeks, which provides sufficient time to observe them for any signs of pests or diseases that may not have been noticeable at the outset. This timeframe also allows the succulents to gradually adjust to their new environment, adapting to differences in lighting, humidity, and temperature—factors critical for their acclimation and stress reduction.

    If you identify any health issues during the quarantine period, address them promptly with suitable treatments and continue monitoring until you're certain the plant has fully recuperated. Treatment is usually time-consuming, and it may be necessary to prolong the isolation beyond the standard two to four weeks. Continue providing care and observation until you're confident that all problems have been resolved. Only after verifying that your new succulent is completely healthy and pest-free should it be placed alongside your other plants.

    Extra Tips

    • After the quarantine time, begin integrating your new plants into your regular care routine slowly. If you've been keeping it in a shadier spot for quarantine, gradually move it to brighter light to avoid shocking it with a sudden change.
    • If you repotted the succulent during quarantine, continue monitoring its adjustment to the new soil and pot.
    • Even after moving your succulent out of quarantine, keep an eye on it for a few more weeks as it settles into its place among other plants. Watch for any delayed reactions that might indicate stress or latent disease.
    • Be attentive to how other plants react to the newcomer; sometimes issues can take time to manifest.
    • Hold off on fertilizing your new succulent until it has fully acclimated to its new environment. Fertilizing too soon can add additional stress because the plant is not yet ready to take up extra nutrients and use them effectively.
