I’m looking for information on how to harvest and care for yucca seeds. How do you plant them, when do you pick them, when do you plant them (spring/fall), and when do you pick them? I have a Yucca that has flowered for the past two years, and it is currently laden with seed pods, and I’m not sure what to do with it.
Gather the seeds as soon as the seedpod begins to crack open. If you wait too long, the seeds will fall out when the pod fully opens. Remove the seeds from the pods, dry them, and store them for the winter in a cold, dark place. Start the seeds inside at the same time as your other transplants, or wait until the threat of frost has gone and the soil temperature has reached 55 degrees. The seeds take four to six weeks to germinate. Before planting, some gardeners soak the seeds overnight. Because germination is typically irregular, sow more seeds than the number of plants you want. You’ll have enough of seedlings to distribute if the majority of seeds sprout.
What can you do with yucca seed pods?
Yuccas have a beautiful white to cream flower stem with drooping petals. These panicles will remain for a few weeks before the petals fall off and the ovary begins to form. Seed pods will appear soon. Allow these to ripen on the plant until they are completely dry before harvesting. You can also cut off the seed pods on yucca to prevent the plant from self-seeding. Future blooms will not be affected by cutting the stalk.
Yucca seed pods will cover the whole length of the flower stalk. They have a firm, dry husk and are about one inch (2.5 cm) long. Many black, flat seeds are found inside, which are the source of baby yuccas. The yucca seed pods are ready to gather once they have dried. Gather the seeds by cracking open the pods. They can be kept in the refrigerator in sand until you’re ready to plant them. They’ll last for up to five years.
Outdoor yucca seed pod propagation should begin in the spring, although they can be started indoors at any time. The easiest technique to multiply yucca seeds and manage the growing environment is to plant them inside. The seeds must first be soaked for 24 hours. Yucca seed pods have a hard shell that must be softened before the seed can germinate.
How do you germinate yucca seeds?
I’ve owned a yucca plant for a long time. This past summer, it finally flowered. It produced seed-bearing pods. Can I use these to start new plants? If so, how would you go about doing it?
Remove the seeds from the pods and store them for the rest of the winter in a cold, dark area. You must begin the planting process as soon as possible. It takes 30 to 35 days for these seeds to germinate. Early March is the best time to start the seedlings indoors. Use a soilless potting or seed starter mix that is sterile. Keep the soil moist and at a temperature of about 55 degrees. Place the young seedlings under grow lights or in a bright sunny window once the seeds have sprouted. Seed-propagated plants need 45 years to blossom.
Can you plant the whole seed pod?
- Simply add water to the soil to allow it to expand, then plant your seeds and watch them grow.
- Plants are started indoors and grown to a specific size before being transplanted into the garden (see transplanting).
- It’s a lot of fun to start plants indoors.
- All you have to do now is fill the container with water, drop in your seeds, and wait for them to sprout.
How do you grow red yucca from seed pods?
As soon as the pods are mature, take one or two and break them open. Shake the seeds out of the pods after breaking them open. Pick through the seeds, removing those that appear to be underripe or have visible indications of damage. Red yucca seeds are best sown right once, but they can also be stored in a cold, dry spot for later planting.
Can you start yucca plants from seeds?
If the pods were still green when you removed them off the stalk, they were removed prematurely. Before they may be removed off the plant, they must be black or extremely dark brown in color and beginning to split.
We discovered that one yucca endemic to North America can grow in climates that aren’t normally called yucca country; that is, climates that aren’t desert. In Illinois, Yucca filamentosa (Adam’s needle) does grow naturally. We’ll assume that’s the yucca you have because the propagation instructions for the genus Yucca should be quite similar. These propagation instructions can be found by following the above link to our Native Plant Database webpage on that yucca:
Fresh seed stored over the winter will germinate quickly in Yuccas. Seeds germinate best in temperatures between 60 and 70 degrees Fahrenheit. Yuccas can also be propagated from rhizomes, stem cuttings, or offsets dug from the side of existing plants.
Gather seeds as soon as the capsules begin to dry but before they split. Allow to dry completely before crushing to remove the seeds. Keep seeds in damp sand in the refrigerator over the winter. Keep in sealed, refrigerated containers for longer storage durations.
We collected and packaged yucca seeds for the Millennium Seed Bank at the Lady Bird Johnson Wildflower Center. Crushing the pod to get the seeds is more difficult than it appears. We discovered that pliers worked about as well as anything else, although it was still a fight. Seed channels can be found inside the broken pod. They’re flat, black wafers that are extremely thin. You could notice a clean, round hole bored up the center as you draw out a stack of them. The larvae of the yucca moth have been feasting on the seeds in this nursery. The yucca moth, on the other hand, is required for the plant to flower. Here’s another quote from the website:
“Yuccas rely on the Yucca Moth for pollination, while the Yucca Moth relies on yuccas for nourishment. When the yucca flower is in bloom, the female moth collects pollen from the anthers and flies to another yucca flower, where she deposits a number of eggs amid the ovules in the ovary (immature seeds). The pollen mass is then placed on the flower’s stigma, ensuring pollination and the development of the ovules into seeds. The larvae of the moth consume the seeds as they grow larger. Many of the seeds are unharmed and subsequently spread, potentially resulting in the growth of new plants. When the larvae reach adulthood, they leave the seed capsule, fall to the ground, and pupate. As the yuccas begin to flower, the adult moth emerges the following season.”
No, the seeds with holes aren’t viable, but the yucca produces a lot of seeds, so you’ll discover some that are whole if you keep looking. More information and photographs of the seed can be found in this Floral Genome Project on Yucca filamentosa (greatly magnified). Even if you have other Yucca species that you think are living in Illinois deserts, the propagation methods will be the same.
How do you start a yucca plant?
Yucca can be propagated through division, root cuttings, stem cuttings, and seeds, among other methods. Cut stems and offsets, strip the lowest few inches of leaves, then plant and treat cuttings tenderly until they root. You can collect yucca seeds and plant them, however the seeds take a long time to sprout. You can also dig up a part of rhizome with a shovel, divide it into 3-inch sections, and plant it. In about a month, rhizome cuttings should show signs of growth. It’s simple to turn a single yucca into a flock of yuccas.
Do yucca plants need full sun?
There are over 20 different species of yucca. Depending on the cultivar, the hue of yucca plants vary from green to bluish, with cream, yellow, and white variegations. Yucca plants have huge, woody stems that grow on canes.
The upkeep of a yucca houseplant is simple once it has been planted in a sunny to partly shaded spot indoors. For optimal leaf color, place the yucca plant in a somewhat shaded spot with bright but indirect light while growing it indoors. Potted yucca plants can thrive in full sun, but browning tips or white, necrotic areas on the leaves are common.
How long does a yucca take to grow?
The yucca plant thrives in a variety of settings as long as it has adequate space for its roots, receives enough sunlight, and receives enough water. Because it can be difficult to get a yucca to germinate from seed, many gardeners prefer to start with a cutting from a mother plant. Allow adequate space for a cutting to develop roots in well-draining soil and wait patiently.
The normal yucca matures in two to three years, but it can take up to five years or longer to produce a flower spike. Choose this lovely perennial and you’ll be able to enjoy growing a tree, shrub, or bush for decades.
If grown outside, yuccas can reach astounding heights, and if grown indoors, they may require frequent pruning after they reach 10 feet. The yucca plant prefers a lot of room and doesn’t require much care. If the soil is overly damp all of the time, this plant is susceptible to disease, root rot, and pests. Because the yucca plant is divided into over 40 species, not every variant is suitable for eating or grows in the same way. The length of maturity and pace of growth are also affected by the variety and environment. Pruning and modifying the watering schedule of a yucca might help you control it.
Growing Yucca Outdoors
The yucca is a magnificent and fascinating plant to have in a garden or to use in landscaping. Prepare to wait years and devote time to cultivating your yucca in order for it to produce its signature flower spike. Wear gloves when touching the leaves because they are sharp. Check the area around a yucca to make sure any new offshoots that have sprouted aren’t fighting for space if they are too close.
To produce magnificent results, plant a yucca in a region where the roots can grow broad, reach deep, and there is enough of sunlight. Allow a yucca to acclimate to the cyclical precipitation patterns when it’s outside, and don’t worry if it doesn’t get enough water. These plants are difficult to kill and are native to arid regions with little rainfall. Pruning when needed, a slow-release fertilizer, and plenty of patience are all that’s required for maintenance.
Growing Yucca Indoors
The most important thing to remember when growing yuccas is to leave adequate area for their roots, provide plenty of sunlight, and prevent overwatering. A good mix of coarse sand, potting soil, and drainage is required for indoor kinds.
During the spring and summer, prune the stalk and any blossoms to the proper length to keep the plant’s height under control. The yucca is unconcerned about the pH of the soil and can withstand almost everything, with the exception of too much water and insufficient sunlight. Because yuccas can become brittle when exposed to intense sunshine, this attractive plant is best suited to a western-facing window.
Collecting seed
- Collect mature seed as soon as the seedheads (e.g. capsules or pods) ripen on a dry day. A color shift from green to brown, black, or red is frequently indicative of this, but it must occur before they open and lose their contents.
- Pick the seedheads and set them out to dry on a greenhouse bench, a warm windowsill, or in an airing cupboard, either singly or on stalks. This makes seed extraction from pods, cones, and capsules much easier.
- If the pods and capsules do not open when dry, gently smash them to release the seed.
- By crushing fleshy fruits and berries in a fine screen and then rinsing away the pulp in cold water, you can get seed from them. Allow the seed to dry on paper towels for a few days.
- Every few days, check for exploding seedheads. Place a sack over them and shake; the ripe seedheads will usually explode into the bag. Alternatively, as the seedheads turn brown, take them from their stems and place them in a marked paper bag.
- Hand-picking nuts or laying a sheet at the base of the tree and shaking the branches until they fall should be done around the time they would naturally fall.
- Clean out any surrounding debris (chaff) adhering to the seed after extracting it, as this material could decay and cause the seed to dampen. Molds, parasites, and diseases can all be found in chaff.
