pro tip

give them room to bloom

Snapdragons like to have a bit of personal space. Make sure to leave about 6 to 12 inches between each plant to provide ample space for them to expand and thrive. Plus, it can actually help prevent the spread of diseases. These aren’t wallflowers—they like a little room to show off their vibrant blooms!

fun fact

snap it open!

The name ‘Snapdragon’ comes from an old superstition that says if you hold the flower by the stem and squeeze it, its mouth will “snap” open and close. They may not actually snap at you, but it’s still a fun way to engage with these beautiful plants! So don’t be afraid to give them a gentle squeeze and watch their petals snap.

beyond the basics

  • soil and potting  

    Snapdragons thrive in nutrient-rich, well-draining soil like Miracle-Gro® Moisture Control® Garden Soil. For outdoor planting, choose a sunny spot with ample spacing of 6 to 12 inches. In containers, use a pot that is at least 12 inches deep and wide, providing the roots with enough space to expand and thrive. Also, make sure the pot has good drainage to keep those roots from getting waterlogged.

  • companion planting

     Snapdragons are versatile plants that effortlessly blend into any garden. They complement summer blooms like petunias, lavender, and sunflowers, as well as aromatic herbs like rosemary and sage.

  • blooms

    Different varieties of snapdragons have single, double, or frilly petals and come in many vibrant colours. The most common variations are tall snapdragons that feature flowers with broad petals on strong stems, dwarf snapdragons that boast delicate blooms in an array of colours on short stems, and double snapdragons which feature multiple rows of ruffled petals.

  • pest control

    Snapdragons generally are resistant to pests, but it’s important to keep an eye out for aphids and thrips. If you happen to spot any of these pests, it’s recommended to employ natural methods such as using an insecticidal soap like Ortho® Bug B Gon® ECO Insecticidal Soap or rinsing the foliage thoroughly with a forceful stream of water to dislodge any potential invaders.

troubleshooting

  • why aren’t my snapdragons blooming enough?  

    Insufficient sunlight exposure or subpar fertility conditions. To ensure your Snapdragons thrive, ensure your plants receive a minimum of 6 hours of direct sunlight each day. To improve soil fertility, you can enhance it by incorporating a nutrient boost like Miracle-Gro® Water Soluble All Purpose Plant Food. This will enrich the environment for your plants and promote their growth. Also, to encourage the formation of new buds, try deadheading to clear up any withered blossoms.

  • why are my snapdragon’s leaves powdery?  

    Fungal disease. This tends to appear in warm and humid climates. To prevent and treat this condition, ensure adequate air circulation between plants by leaving sufficient space when planting, avoid wetting the foliage during watering sessions, and use fungicides if necessary.

  • why does it look like my snapdragons are wilting?   

    Over watering or under watering. Excess moisture can result in root rot, hindering your flowers’ ability to absorb essential nutrients. Conversely, a lack of moisture can cause your flowers to dry out or wither. To ensure optimal growth, carefully assess soil moisture levels and adjust watering practices accordingly.

  • why are my snapdragons falling over?   

    Insufficient sunlight. To address this, try moving the plant to a spot that ensures 6 hours of sunlight. Additionally, consider pruning the leggy stems and using supports such as stakes or trellises to help the stalks stand tall.
