How to Plant and Care for Your Mexican Blooms
Success with these plants comes down to mimicking there native growing conditions. Here’s a step-by-step guide.
Step 1: Choose the Right Location
Almost all Mexican flowers demand full sun. This means at least 6 to 8 hours of direct sunlight per day. Without enough sun, plants will become leggy and produce few flowers. Ensure the site has good air circulation to help prevent fungal diseases.
Step 2: Prepare the Soil
Well-draining soil is non-negotiable. These plants despise wet feet. If you have heavy clay soil, you’ll need to amend it.
- Loosen the soil to a depth of about 12 inches.
- Mix in a generous amount of compost or well-rotted manure.
- For raised beds or containers, use a high-quality potting mix.
- Avoid soils that stay soggy after rain.
Step 3: Planting Correctly
Whether you’re using seeds, tubers, or nursery plants, timing and technique matter.
- Timing: Wait until all danger of frost has passed. The soil should be warm.
- Seeds: Follow packet directions for depth. Zinnias and Tithonia prefer direct sowing.
- Tubers (Dahlias): Plant horizontally, about 4-6 inches deep, with the eye (growth point) facing up.
- Transplants: Gently loosen roots before planting at the same depth they were in the pot.
Step 4: Watering Wisely
Water deeply immediately after planting to settle the soil. Then, establish a smart watering routine.
- Establishment Phase: Water regularly for the first few weeks.
- Mature Plants: Once established, water deeply but infrequently. Allow the soil to dry out between waterings.
- Best Practice: Water at the base of the plant in the morning to keep foliage dry.
Step 5: Feeding for Fantastic Flowers
While they aren’t heavy feeders, a little nutrition goes a long way for bloom production.
- At planting, mix a slow-release, balanced fertilizer into the soil.
- During the growing season, you can use a liquid fertilizer low in nitrogen but higher in phosphorus (the middle number on the fertilizer bag) to promote blooming.
- Over-fertilizing, especially with nitrogen, can lead to lots of leaves and few flowers.
Step 6: Pruning and Deadheading
To keep your plants looking tidy and flowering non-stop, simple maintenance is key.
- Deadheading: Regularly remove spent flowers by pinching them off. This tells the plant to produce more blooms instead of setting seed.
- Pinching: For bushier plants like Zinnias, pinch off the top set of leaves when the plant is young.
- Pruning: For vines like Bougainvillea, prune after a flush of blooms to shape the plant.
Common Challenges and Solutions
Even tough plants can face a few issues. Here’s how to handle them.
Pests
Aphids and spider mites can sometimes be a problem, especially in dry conditions.
- Spray aphids off with a strong stream of water from your hose.
- For mites, increase humidity and use insecticidal soap if needed.
- Encourage ladybugs and other beneficial insects that prey on pests.
Diseases
Powdery mildew (a white film on leaves) is the most common issue, often casued by poor air circulation or overhead watering.
- Always water at the base of the plant.
- Space plants properly to allow for good air flow.
- Remove and dispose of severely affected leaves.
Overwintering Tender Perennials
In colder climates, plants like Dahlias need special care to survive the winter.
- After the first frost blackens the foliage, carefully dig up the tubers.
- Cut the stems back to about 6 inches and let the tubers dry for a day.
- Gently brush off excess soil and store them in a box filled with slightly moist peat moss or vermiculite.
- Place the box in a cool, dark, frost-free location like a basement or garage.
- Replant in the spring when the soil is warm.
