What Is Red Yucca?

The red yucca is a member of the Asparagaceae family, which also includes the agave (Aloe spp., Agave americana and others), Alocasia, anthurium (Anthurium spp.), Dieffenbachia and Spathiphyllum.

Sharing characteristics with both ornamental plants and houseplants, the red yucca is a durable plant that can tolerate hot and cold temperatures. Most gardeners will recognize this plant as being unique because of its height and color. It is not often seen in other parts of the United States or Canada.

Red Yucca Care & Maintenance:

Red yucca plants require very little effort to grow and maintain. They like to be watered when the top inch of soil is dry, but they should never be allowed to sit in water. In addition, it doesn’t need much fertilizer either; fertilizing once every two months during spring and summer with a slow-release granular fertilizer will suffice.

During fall and winter, it’s best to withhold fertilization as it goes into hibernation mode at this time of year. The only maintenance needed for red yuccas during this time of year is to remove dead leaves from the plant’s center crown area.

Where To Buy:

Light Requirements:

Red yucca plants do well in a variety of light conditions. They can thrive with either high or low levels of sunlight and will do equally well indoors or outdoors. This is an excellent houseplant to bring along to your summer cottage, as it thrives in both indoor and outdoor lighting conditions.

Outdoor Care for the Red Yucca

Red yucca plants are wonderful landscape specimens that don’t need much care to grow and maintain. These plants are very durable and will tolerate periods of drought as well as periods of flooding when grown outside (provided they’re planted inappropriate soil).

During months that are freezing, red yuccas should be brought indoors or stored undercover so they won’t sustain any damage if temperatures drop too low.

When planting red yucca outdoors, the spacing between plants should be at least 2 feet apart. Although frost won’t kill them, it will slow down their growth considerably if temperatures drop below freezing for extended periods of time.

For best results, plant in areas with well-draining soil so roots are not submerged nor waterlogged during wet weather or periods of heavy rainfall.

Water Requirements:

Although red yuccas require a steady supply of water, it is important to prevent both waterlogging and drought conditions. During hot summer months, plants should be watered every other day when the soil has dried out well. If you have over-watered your plant, you may notice yellowing leaves as your plant struggles to recover from being drenched.

It’s best to water in the early morning or late evening hours so the plant does not sunburn due to excessive sunlight exposure during these periods. Water lightly after watering so that any excess moisture will rapidly evaporate which prevents disease issues on the foliage and root system.

Soil Requirements:

Red yucca plants prefer a loamy type of soil with good drainage and organic matter. In addition, it is important to ensure that soil pH levels are between 5.5 and 6.8 for optimum growth and health of the plant.

If your soil has acidic levels (below 5.5), you can add a small amount of sphagnum peat moss or organic compost to improve its texture so the roots have room to grow and develop into strong plants without being constricted by compacted soils.

Red yucca plants require very little in terms of fertilization; once every month during summer months is generally enough to sustain vigorous growth year-round except during winter months when not much growth takes place anyways due to cooler temperatures outdoors.

You can also apply organic fertilizer periodically throughout the spring/summer months to promote healthy foliage and increased flowering.

If you’re planting red yucca to use as a decorative specimen in your yard, be sure to allow plenty of room between the plants so it has room to spread out and form an elegant mound shape with its large leaves cascading down along the ground.

Do not plant these plants too close together because they will eventually grow into each other due to their extensive root system that expands outward over time into neighboring vegetation.

Temperature and Humidity Requirements:

Red yuccas are extremely hardy plants that can tolerate extremes in temperatures. Although they prefer warmer weather, these plants will grow just fine in areas with very hot or cool conditions and they can even tolerate light freezes if well protected – without any destruction to the plant itself.

However, you should take care not to overwater during cooler periods outdoors as this could result in root rot due to slower drainage of water while the soil is frozen. If outdoors becomes too cold for extended periods, bring indoors before frost hits so your plant does not sustain any damage from adverse weather conditions.

Do not allow the soils to get soggy when watering; water thoroughly but lightly so your plant doesn’t become pestered by fungus issues down its roots or foliage.

Unlike many of its close relatives, red yucca plants actually prefer higher humidity levels for optimum health and growth. For best results, place in a bright area with good air circulation so the foliage doesn’t become waterlogged which could trigger root rot issues over time.

If leaves begin to droop or turn brown as if they’re wilted but the soil is moist, the plant probably needs more light and/or better ventilation which can be improved by moving outdoors during the summer months to enjoy optimal growing conditions.

If your plant displays this type of symptoms indoors when it’s supposed to be warm outside, it may indicate that temperatures are too low at indoor levels even if you provide adequate light conditions or supplemental heating (such as heat lamps).

Fertilizing Requirements:

Red yucca plants are extremely fast-growing, low-maintenance plants that require only moderate amounts of fertilization to sustain healthy growth.

For best results, apply slow-release granular fertilizer approximately twice per month during the spring/summer months to promote healthy foliage and increased flowering for the desired effect.

If you feed too much fertilizer at one time the red yucca plant can be prone to leaf burn due to excessive nutrient uptake by the flowers or leaves so it’s better to feed small doses often rather than large servings once a month; especially if applying more than 10-15% nitrogen in your fertilizer mixture.

Do not add any types of high potassium (over 5%) fertilizers such as bone meal since this could damage the plant’s tissues over time due to its high salt content.

Potting and repotting Requirements:

Although red yucca plants are often grown in the ground outdoors in warmer climates, they can be easily forced into a pot to create a beautiful potted specimen indoors.

If growing inside, select a large container that has plenty of room for root growth and soil volume so the plant doesn’t become cramped or waterlogged which could trigger pest and disease issues over time.

Mix organic peat moss with loam-based potting soil at equal levels (1 part peat moss to 1 part loamy earth) to provide adequate drainage along with nutrition for healthy roots production.

If you choose not to use potting soil (such as commercial mixes), add extra perlite or vermiculite at least 10% by volume since this will help airflow into the soil and decrease too much moisture retention (which could lead to rotting issues).

Place two or three inches of coarse gravel at the bottom for drainage then fill your container almost full with roots-mixed potting soil.

This will leave enough room at the top to add more potting soil as your plant grows to prevent damage or shock due to root crowding.

If it’s possible to get a known variety, place your red yucca plant directly into its permanent planting spot so you can easily move it outdoors in warmer weather and still know where it is for easy access.

Otherwise, consider using stakes to train your plant while it’s young; this will keep it from drooping until you’re absolutely sure you’ll be keeping it long-term.

When moving outdoors in the summer, keep your red yucca plant out of direct sunlight that could scorch its foliage on hot days and expose it to pests; hanging baskets or protected areas are ideal places to grow this species outside.

Red Yucca Propagation info:

Given proper conditions and care, red yucca plants can be easily propagated through division, cuttings, or seed.

The division is the preferred method of propagation for this species since division will propagate an exact genetic copy of the parent plant which makes it ideal for collecting your favorite subjects to share with friends.

Seed may take up to 2-3 years to develop into mature plants so it’s not always a viable option; plus if seeds are collected from non-sterile sources there could be hidden diseases or pathogens that shorten their life expectancy even further.

Propagation by leaf cuttings is relatively easy and quite successful but you’ll want to keep in mind that leaves have limited food reserves during this state so they only

Red Yucca Problems:

If your care for a red yucca plant is lacking to any degree, you could experience problems such as stunted growth or even death from various diseases and pest attacks.

Leaf discoloration/fungal diseases: This condition often starts with the tips of leaves turning yellow then brown; eventually spreading inward toward the veins which can turn grayish-black in color.

Sometimes these fungi will also attack the stems or roots of your subject if they’re exposed to excessive moisture and humidity (high relative humidity like 80%+).  The best prevention method for this situation is water early in the day so plants have time to dry out throughout most of each day.

A good rule of thumb is to give them a thorough watering just as the sun starts to rise then leave at least 2″ of space between soil and container so air can circulate.

Red yucca plants are susceptible to pests such as aphids, mealybugs, spider mites, and root-knot nematodes; if any of these organisms appear they should be removed immediately because of severe stress or damage caused by them could lead to death.
