    About Agave franzosinii

    Agave franzosinii is a large, slow-growing agave plant native to Mexico. It’s usually grown as an outdoor feature in gardens because of its large, attractive foliage and flowers.

    Agave franzosinii has thick, glaucous green leaves that can grow quite long and have teeth along their edges. The leaves form a rosette, overlapping each other at their bases.

    The plant produces large yellow flowers on an extremely tall spike (40 ft.). It serves as an excellent main feature in desert gardens.

    Agave franzosinii Care

    Agave franzosinii is a beautiful succulent plant and one of the easiest to care for. Amateurs and professionals alike will find this Agave an excellent addition to their landscape.

    Light

    Agave franzosinii is a succulent plant that requires full sun to thrive but can tolerate some shade. If you want to grow your Agave indoors in hot, dry climates, choose a location with plenty of natural light or invest in grow lights.

    Soil

    The soil for this Agave should be well-draining, sandy, and slightly acidic. A good mix is one part potting soil and two parts perlite or sand.

    Water

    Agave franzosinii is a drought-tolerant plant, so water it sparingly. Water thoroughly when the soil is bone dry to about 1 inch deep, and then allow it to lose water again before the next session.

    Overwatering is the root cause of most problems these succulents face, and preventing it from happening will ensure your Agave’s long and healthy life.

    Temperature and Humidity

    The ideal temperature range for Agave franzosinii is between 55 and 75 degrees Fahrenheit. It can survive in cooler temperatures but will grow more slowly. Consider relocating your plant to a warmer spot if your house is consistently cool.

    You should keep humidity above 40% for your plant to thrive. There is no need to increase moisture, as the humidity in your home should be high enough to keep your plant healthy.

    Fertilizer

    Agaves grow slowly and are long-lived, which makes them relatively independent from fertilizers. At most, you should fertilize them once every six months with a standard balanced fertilizer. Use a slow-release fertilizer to ensure your plant does not get too leggy or tall.

    Avoid fertilizing in winter as the plant will not grow much at this time, and the roots will not absorb your fertilizer.

    Pruning

    Agaves should not be pruned unless necessary.

    These self-contained plants limit their growth, and you can’t really affect anything without scarring the plant’s aesthetic.

    Only prune dead or dying leaves if you see them. Otherwise, leave your Agave franzosinii to their own devices.

    Potting and Repotting Agave franzosinii

    Agave franzosinii can be repotted, but you should do this sparingly. If your plant becomes too large for its pot and the roots start encroaching on neighboring plants, it’s time to repot it.

    When you do so, use a container that is only slightly bigger than the one before so as not to shock your Agave with sudden changes in size or soil composition.

    Prepare

    • Prepare the pot. Use a clay or terracotta pot of the same size or slightly larger than the one you’re replacing. If it’s larger, use a combination of soil and pebbles to fill up the extra space around your plant.
    • Prepare the soil. Use a light, sterile potting soil with plenty of perlite or vermiculite added. These ingredients will help aerate the soil and provide good drainage.
    • Choose the spot. Place your new pot in a warm, sunny area protected from wind and rain.
    • Gather the tools. You’ll need a trowel or shovel, a pair of pruning shears, and a watering can.

    How to Repot (Step-by-Step)

    1. Remove the plant from its old pot. Use your trowel or shovel to loosen the soil around the base of your plant, then gently pull it out.
    2. If the Agave’s roots have grown through the drainage holes in your old pot, cut them off with pruning shears before planting.
    3. Set the plant in a new container. Place some pebbles into your new container, then set your plant upright on top of them. Fill in around the roots with more well-draining potting soil, ensuring there are no air pockets.
    4. Water the new container until it begins to drain from the bottom.

    Propagating Agave franzosinii by Offsets (Step-by-Step)

    After flowering, Agave franzosinii has the habit of splitting into rhizomes that can be repotted and grown as individual plants. To grow from a rhizome:

    1. Simply cut the rhizome from the mother plant and place it in a new container filled with potting soil.
    2. Allow the cut end to heal and callus over before replanting.
    3. Plant the offset in a pot with a well-draining potting medium
    4. Water sparingly and keep in a warm, humid environment until new growth begins to show.

    Blooms

    Agave franzosinii blooms well after the plant matures (after 15 years), with a spike reaching as high as 40 feet (12 m).

    The flowers are bright yellow and quite large. They are incredibly showy as well.

    After flowering, this Agave will die. You will have to propagate anew if you want to continue the culture.

    Toxicity

    Agave franzosinii is mildly toxic, with sap that can cause skin irritation and inflammation.

    NOTE: This page is not intended as a substitute for veterinary advice. The toxicity of an ingested substance varies depending on the amount ingested, the animal’s weight, and its sensitivity to specific allergens. Contact your veterinarian or local animal poison control center immediately if you think your pet may have ingested a toxic substance.

    Common Pests

    Agave Franzosinii Leaves

    Agave snout weevil

    Agave snout weevil is a common pest of Agave franzosinii. The snout weevil lays its eggs inside the plant, and when the young hatch, they eat their way out of the leaves and into other nearby plants.

    Scale Insects

    Scale insects are small, hard-bodied insects with a round shape. They attach themselves to the leaf surface and suck out the sap, which causes leaves to become discolored and die back.

    Use neem oil or horticultural oil to treat the affected areas.

    Slugs and Snails

    Slugs and snails feed on the plant’s leaves, stems, and roots. Set poison bait or sticky traps around your yard to control these slimy pests.

    AVOID

    • Overwatering
    • Placing under harsh sunlight
    • Using poorly drained potting mediums
    • Fertilizing during dormancy

    Common Problems

    • Overwatering: Overwatering your plant can cause root rot. Try to water only when the top inch of the soil is dry. If you have an established plant that seems to be wilting even though you haven’t watered it lately, check the soil for moisture before watering again.
    • Overfertilizing: Overfertilizing can cause your plant to experience stunted growth and become disease prone. To avoid this, only fertilize once a year at the beginning of the growth phase. Then, use half the recommended dosage to reduce the chance of overfeeding even further.
    • Frost burn: Frost burn occurs when the plant is left outside during cold weather and freezes. The damage can be minimal, but more often, it’s severe and permanent. If your plant has experienced frost burn, cut off dead growth as soon as possible to limit its spread.

    FAQ

    Yes, you can touch your Agave franzosinii plant. It’s not toxic like some plants, but it does have thorns that will hurt if you get jabbed by one.

    Agave franzosinii has pups after it’s done flowering, which only happens to mature plants. This means you won’t have to worry about your plant reproducing outside your control.

    In ideal conditions, the Agave franzosinii can grow up to eight feet tall and ten feet wide. However, it’s likely that yours will only reach this size well after a decade.

    The Agave franzosinii needs full sun and well-draining soil. It’s best to plant it in sandy or rocky soil so that water drains away quickly rather than sitting stagnant around the roots.
