General Information

  • Instruction By Kat Malstead
    Notes a lovely, fragrant addition to a butterfly or hummingbird garden, Buddleja comes in many colors from white, yellow, rose, lavenders, to a deep purple. Care must be given to avoid invasiveness, as this plant can reseed and create havoc in wild places if left unattended. Pruning after blooms die is a necessity to avoid this. The shrub itself has a weeping form, is semi-evergreen in milder zones, and can get 6\'-12\' tall by 4\'-14\' wide. Give it some elbow room! Likes good drainage, average soil, good circulation, and normal watering. They can be drought tolerant once established. Needs full direct sun. Deadhead old blooms for a continuous summer show.

    April
    1. Buy

    If you can find this plant in April, buy it! That way, it\'ll have a chance to get established, and you will have a crop of blooms in July-Aug.
    2. Plant

    Planting in April --if possible-- will give the plant an opportunity to develop its root system and should provide you with a summer\'s worth of delight.
    May
    1. Plant

    If April doesn\'t suffice, May will definitely!
    2. Mulch

    a nice spring mulch will help protect the shrub from the summer heat and help nourish the roots.
    3. Pest/Disease Inspection

    The ubiquitous aphids enjoy the new growth, as well as flea beetles & leaf hoppers.
    4. Treat for Pest/Disease

    Spray Neem oil upon observation of pests, but I suggest spraying early in the morning to avoid spraying your ladybugs and butterflies.
    5. Transplant

    For small starts, (less than 8\"-12\") transplant in May and make sure to water during the hottest part of the summer.
    June
    1. Fertilize

    a light fertilizer heavy on the phosphorus will improve bloom, and be a benefit to the plant overall.
    2. Propagate

    softwood cuttings in a 60%-perlite/40% coir or vermiculite medium. Keep well misted until rooted. Over winter starts and plant out following spring.
    July
    1. Water

    Buddleja likes it relatively dry, and will tell you by leaf droop if it is thirsty. (But try to avoid waiting that long!) During the very hot summer months, a bi-weekly watering may be necessary.
    August
    1. Water

    Buddleja likes it relatively dry, and will tell you by leaf droop if it is thirsty. (But try to avoid waiting that long!) During the very hot summer months, a bi-weekly watering may be necessary.
    September
    1. Water

    Buddleja likes it relatively dry, and will tell you by leaf droop if it is thirsty. (But try to avoid waiting that long!) During the very hot summer months, a bi-weekly watering may be necessary.
    2. Prune

    After all blooms are finished, I cut mine back by about one third to one half. Pruning is dependent on when the shrub is done with its blooming dance.
    3. Pest/Disease Inspection

    Buddleja can be subject to black spot.
    4. Treat for Pest/Disease

    Neem oil works great for black spot, spray weekly for one month upon observation of black spot, mildews or other fungal diseases.
    October
    1. Prune

    After all blooms are finished, I cut mine back by about one third to one half. Pruning is dependent on when the shrub is done with its blooming dance. :~)
    2. Mulch

    mulching after the first frost will help protect the root system from winter damage. Make sure it is after the first frost, or else the shrews and voles will come party.
    3. Protect

    a nice thick mulch for winter will help protect the roots against freeze damage.
    4. Transplant

    Transplanting in Oct will ensure that the root system gets developed over the winter. New growth will occur below the soil surface, rather than above.
