Angelonia Summer Snapdragon Care

When angelonia plants grow, it has a tough nature, and flowers bloom for a long time, making them a staple in flower gardens. Angelonia grows nectar-rich flowers, attracting pollinators to your sunny garden.

It is a low-maintenance plant that does not need deadheading and will greet 👋 you with many blooms for weeks.

Angelonia Flowers Light Needs

Plant angelonia in a spot where it can reach full sun to flower continuously during the blooming season. When angelonia plants do not receive at least eight hours of direct sunlight, they become leggy and bloom less.

Angelonia Prefers Soil Evenly Moist

well-draining soil for angelonia

You can grow angelonia plants in different soils, but they prefer a pH of 5.5 to 6.2. Please provide them with well-draining soil that is evenly moist with a layer of organic mulch to help reduce watering to fertilizing.

For heavy clay soils, we recommend amending it with coarse sand, whether grown in a flower or container garden.

Watering Angelonia Angustifolia

Angelonia flowers are quite a drought-tolerant plant and only need watering when the top few inches of the soil are dry. You can provide supplemental moisture when you provide well-draining soil.

Temperature and Humidity

The Angelonia angustifolia does well in hot weather with high humidity. But if you live in the southwest, its drought tolerance is fairly good, but it can benefit from added watering.

Fertilizing Summer Snapdragon

Liquid fertilizer for angelonia

You can feed your angelonia flowers monthly during the growing season, as too much fertilizer will encourage branching with less flowering. Feed your plant with a flower fertilizer when planting to eliminate feeding again.

We recommend you feed plants with a liquid feed diluted.

Pruning Angelonia

These low-maintenance plants do not need deadheading to encourage blooms, but you can pinch them back when young to make them grow bushier.

Potting and Repotting

When you grow angelonia flowers, you will have constant blooms that grow well in plant pots. You can grow them alongside a pool or patio to attract birds and butterflies. But choose large containers with a diameter of 18 inches as they will not dry out fast.

Provide angelonia plants with a well-draining potting mix with enough drainage to prevent root rot—only water when the first few inches of the soil surface is dry.

Overwintering

You can grow them annually in cooler climates but overwinter them as container plants inside the home. When you notice temperatures dropping at night, you can bring them indoors. Keep your summer snapdragon in bright indirect light in consistently cool temperatures.

Water them once a week, and when the soil temperatures warm up after the last expected frost, you can take them back outside.

How to Propagate Angelonia Flowers

An easy way to ensure you always have angelonia flowers is to use stem cuttings to propagate them.

  1. With a sharp knife, cut three-inch long clippings from the tip of the stem without any flowers on them.

  2. Keep the top leaves and remove the rest of the green foliage.

  3. Fill a small container with a soilless well-drained potting mix and make a small hole with your finger.

  4. Dip the cut end in a rooting hormone and insert it into the moist soil.

  5. Keep the soil moist until you notice new leaves forming to transplant into garden beds.

Growing Angelonia Seeds

Handling angelonia seeds are complicated, and best to look for pelleted seed with a clay coating making them easier to work with.

You can start the seeds indoors six weeks before the last frost in trays. Use sterile well-drained soil, and do not cover the seeds, as the light aids germination.

Provide bright light with warm temperatures and keep them moist. Seedlings emerge in about three weeks and ensure to space seedlings eight inches apart in your garden.

Common Pests

The main problem when angelonia plants grow is aphids which can become a problem in early spring. You can mist your plant with an insecticidal soap twice a week.
