Winter Care: In areas with frost, Angelonia is often grown as an annual. However, in warmer climates, it may survive mild winters. If growing as a perennial, provide protection during cold snaps or frosty periods.
By following these tips for growing and caring for Angelonia plants, you can enjoy a stunning display of colorful blooms throughout the summer months in your garden or containers.
9 Steps for Propagating Angelonia Plant
Propagating Angelonia plants is relatively straightforward and can be done through stem cuttings. Here are the steps to propagate Angelonia:
Select Healthy Parent Plant: Choose a healthy and established Angelonia plant with vigorous growth and no signs of disease or stress. Select stems that are free from damage and have plenty of new growth.
Prepare Cutting Tools: Use clean, sharp scissors or pruning shears to take stem cuttings. This helps minimize the risk of introducing pathogens to the cuttings.
Take Stem Cuttings: Identify a stem on the parent plant that has several nodes (where leaves attach to the stem). Using your cutting tool, take a 4-6 inch cutting from the tip of the stem, just below a node. Remove any lower leaves from the cutting, leaving only a few leaves at the top.
Prepare Cutting for Rooting: Dip the cut end of the stem cutting into rooting hormone powder. This helps stimulate root growth and improves the chances of successful rooting.
Plant Cuttings: Plant the prepared stem cuttings into a container filled with moistened potting mix. Make a hole in the soil with a pencil or similar tool and insert the cutting, gently firming the soil around it to provide stability.
Provide Ideal Conditions: Place the container with the cuttings in a warm, bright location with indirect sunlight. Keep the soil consistently moist but not waterlogged, as excess moisture can cause the cuttings to rot.
Monitor Growth: Over the next few weeks, monitor the cuttings for signs of root development. You may notice new growth emerging from the top of the cutting, indicating that roots are forming below the soil surface.
Transplant: Once the cuttings have developed a healthy root system, typically within 4-6 weeks, they can be transplanted into individual pots or directly into the garden soil. Be gentle when handling the newly rooted plants to avoid damaging the delicate roots.
Continue Care: Provide ongoing care for the newly propagated Angelonia plants, including regular watering, fertilization, and protection from pests and diseases. As they grow and mature, they will reward you with beautiful blooms.
By following these steps, you can successfully propagate Angelonia plants from stem cuttings and expand your garden with these delightful flowering beauties.

Common Pests
Aphids: These small, soft-bodied insects feed on the sap of Angelonia plants, usually congregating on the undersides of leaves. They can cause yellowing, curling, and distortion of leaves, as well as transmit diseases. Aphids can be controlled with insecticidal soap or neem oil.
Spider Mites: Spider mites are tiny arachnids that suck sap from plant leaves, causing stippling, yellowing, and webbing. They thrive in hot, dry conditions and can be particularly problematic for Angelonia plants grown in dry climates. Regularly spraying the foliage with a strong stream of water can help reduce spider mite populations. Additionally, insecticidal soap or neem oil can be effective treatments.
Whiteflies: Whiteflies are small, moth-like insects that feed on the undersides of leaves, causing yellowing, wilting, and premature leaf drop. They also excrete honeydew, which can attract ants and promote the growth of sooty mold. Whiteflies can be controlled with insecticidal soap, neem oil, or horticultural oil.
Thrips: Thrips are tiny, slender insects that feed on plant sap, causing stippling, silvering, and distortion of leaves. They may also transmit plant diseases. Thrips can be challenging to control due to their small size and ability to hide within plant tissues. Insecticidal soap or neem oil can help reduce thrips populations, but multiple applications may be necessary.
Snails and Slugs: These mollusks can feed on the leaves and flowers of Angelonia plants, leaving behind ragged edges and holes. They are most active at night and during periods of high humidity. Hand-picking, traps, or bait containing iron phosphate can be effective methods for controlling snails and slugs.
Common Problems
Overwatering: Angelonia plants prefer well-draining soil and can suffer from root rot if soil remains consistently soggy. Signs of overwatering include yellowing leaves, wilting, and stunted growth. Ensure that the soil dries out slightly between waterings to prevent root rot.
Underwatering: Despite their drought tolerance, Angelonia plants still need regular watering, especially during hot and dry periods. Underwatering can lead to wilting, yellowing leaves, and reduced blooming. Water Angelonia plants thoroughly when the top inch of soil feels dry to the touch.
