Yuccas are native to the southwestern United States and arid deserts growing in coastal sandy dunes of the east, rocky badlands, and grasslands. Yuccas belong to the family Asparagaceae which comprises some 40-50 species. The common name for yuccas is Adams needle. Most yuccas have thick waxy skins to avoid water loss.

Yuccas can reach heights of 4-8 ft growing in zones 5 to 10, this evergreen produces leaves that are tough with a sword-like shape. Yuccas produce beautiful white flowers that are a show stopper, what I love about yuccas is their low maintenance drought-tolerant plants that can grow both out and indoors. For more on yucca plant care let’s take a closer look.

The planting location

The soil type

Because yuccas are native to desert and dry areas, soil that’s well-drained is ideal for yuccas to thrive. Yuccas are used to grow in sandy, gritty soils.

Yucca weevil

The adult of the yucca beetle is one-half of an inch long, black with an elongated snout. The larva which is white grubs tunnels in the flower stalk base, leaves, and the heart of the yucca. There is no cure for this insect except to remove and thoroughly discard the plant. Avoid planting in that area for a few years to discourage re-infestation.

Scales

Scales are among sucking insects that dose damage by sucking the plant’s sap or fluids, scales resemble bumps or small lumps remaining in a stationary or fixed position. In server cases the entire plant leaves may be covered, the use of insecticidal soap or neem oil will bring control. Before applying read and followed the manufacturer’s directions for best results.

Aphids

Aphids are tiny insects that are pared shape doing the same damage as scales, aphids are among some of the easiest garden insect pests to control. A strong spray of water applied to the leaves continually will bring control.

Agave plant bugs

Agave insect pests are 1/2 inch (1.5 cm.), these bugs will pierce the leaves of garden plants extracting the fluids. Brown small scars appear in injured areas, insecticidal soap will bring control.

Two-spotted mites

Two-spotted mites are tiny barely visible to the eyes, mite cause damage by sucking the plant’s fluids. Signs that your plant has a mite issue are spider webbing on the leaves, to bring control apply neem oil or insecticidal soap.

Mealybugs

Mealybugs are easy to spot, these garden insect pests are sucking insects, their secretion or excrement is a sugary substance known as honeydew from which forms a black mold ( sooty mold). Sooty mold causes plants to take on a sickly dusty appearance. Applying insecticidal soap or other pesticides will bring control.
