    Q
    How much Monterey Florel Brand Growth Regulator do I need, and can I use a hose-end sprayer?
    I have 4 old olives, about 25 feet tall.
    A

    Monterey Florel Brand Growth Regulator is applied at 3 oz per gallon of water.  The average size tree will require 5 to 20 gallons of spray for treatment. It should not be applied to trees that are stressed and between 60-95 degrees. We recommend applying using a hand pump or backpack sprayer for more accurate applications. Please refer to the product label for complete mixing and application instructions.

    Q
    Can I spray my olive tree, which is close to a swimming pool, with Monterey Florel Brand Growth Regulator?
    I want to spray my hundred year old olive tree with Florel to retard Olive growth, but if I wait till spring when it flowers, my pool will be filled with water and I'm worried that the spray will go into the water and infect the salt water pool. Should I spray my tree now? Or wait until April or May and cover my pool?
    A

    Monterey Florel Brand Growth Regulator should not sprayed in a way that could contaminate water used for irrigation or domestic purposes. We would recommend covering the pool if you are concerned that overspray may get into that area. Monterey Florel Brand Growth Regulator should only be applied to ornamental olive and other listed plants at the mid- to full bloom stage, prior to fruit set, and generally when temperatures are between 65 and 85 degress.

  • Asked by Grant from Culver City, Ca

    Q
    We sprayed the olive with the Monterey Florel Brand Growth Regulator and the next day we had a bunch of leaves fall. Do you know what may have caused this?
    A

    If the tree is already under stress, Monterey Florel Brand Growth Regulator may increase the stress on the tree. It works on contact only, it does not enter the tree like other growth regulators. Therefore, it will not have adverse growth effects and there is no burn (phytotoxicity) to the new leaf growth.  We would recommend speaking to the manufacturer, Monterey Lawn and Garden, for further assistance. Their phone number is 559-499-2100.

    Q
    How successful is Florel to do away with crabapples? Does anything work permanently?

    A

    Yes, you can use Monterey Florel Growth Regulator to prevent fruit on crabapple trees. You will need to apply as a thorough spray during the mid- to full-bloom stage, prior to fruit set. The only real permanent solution would be to remove the trees.

  • Asked by Randy from Chicora, Pa
    04/09/2019
    Q
    When is a good time of year to spray Monterey Florel Brand Growth Regulator on an apple tree to prevent fruit growth?
    I am from western PA.
    A

    Per the product label: Applications of Monterey Florel Brand Growth Regulator should be made at the mid to full bloom stage, prior to fruit set in spray volumes sufficient to wet, but not to runoff. Failure to wet blooms thoroughly will cause incomplete fruit elimination. Spraying too much (until runoff) may cause some defoliation or other plant injury. Sprays applied too early or too late will be less effective and result in incomplete fruit elimination. The activity of Florel is linked to plant growth activity and is therefore slower-acting when temperatures are low (60ºF) or very high (95ºF). Trees or shrubs should not be under stress when treated such as from drought, insects or diseases. Apply when rain is not expected for 24 hours.

  • Asked by Henrique from Caracas Venezuela
    11/22/2018
    Q
    How much Florel to one gallon of water to get Bromelias blooming ?
    A

    Per the product label: For most bromeliad varieties, mix 8 fluid ounces of FLOREL BRAND GROWTH REGULATOR per gallon of water. This prepares a spray concentration of approximately 2,500 ppm of ethephon. Spray all surfaces of the plant to “wet”. Avoid overspraying to “runoff” which may cause damage to leaves or the growing points. For treating groups of plants, use approximately 1/2 pint of spray solution per 10 square feet of greenhouse bench or outdoor bed area.

  • Asked by Tanya from Gilroy
    05/17/2018
    Q
    Can I use Monterey Florel Brand Growth Regulator on a tree next to my lemon tree?
    I still want lemons, but I don't want the tree gum from the tree next to it.
    A

    Monterey Florel Brand Growth Regulator should not be applied to lemon trees. We recommend that you consult with your local cooperative extension office Master Gardener for a recommendation for protection application.

    You can use Florel on sweetgum trees, but you would need to be sure there is not any overspray or contact on the lemon or other desirable fruit trees.

  • Asked by Phil from Roseville, Ca
    04/04/2018
    Q
    Does Monterey Florel Brand Growth Regulator work on a female Chinese Pestache?
    The berries/nuts are a horrible nuisance.
    A

    Unfortunately, Chinese Pestache and other Pistacia trees are not specific on the product label for Monterey Florel Brand Growth Regulator, so we are not sure if Florel would be effective or not. Per the product label: 

    "A foliar spray of FLOREL BRAND GROWTH REGULATOR will reduce or eliminate undesirable fruit development on many ornamental trees and shrubs such as: Apple, Carob, Crabapple, Elm, Flowering pear, Flowering plum, Horsechestnut (Buckeye), Oak, Olive, Sour Orange, Sweetgum, Sycamore and others. Applications must be made before fruit set for best results."

    We always recommend testing a small portion of a plant to test for tolerance and efficacy for plants not listed on the product label. The rate for fruit elimination is 3 fl oz per 1 gallon of water. Please refer to the label for complete application directions.

    Q
    For how many hours does ambient temperature need to remain above 65 degrees after applying Monterey Florel Brand Growth Regulator?
    For leafy mistletoe control, Monterey Florel Brand Growth Regulator says to apply when above 65 degrees.
    A

    Monterey Florel Brand Growth Regulator should be applied when the constant temperature remains above 65 degrees. This product is only effective during the plant growth. The product should also NOT be applied when temperatures exceed 95 degrees, when rain is expected within 24 hours, during a drought, other other stressful situations including tree/shrub disease or insect damage per the product label.

  • Asked by Richard from Lehi, Utah
    05/27/2019
    Q
    Will Monterey Florel Brand Growth Regulator stop Maple tree helicopter seeds from forming?
    A

    Monterey Florel Brand Growth Regulator works through bloom absorption to prevent fruit set, primarily, so it would not prevent seeds on a maple tree. In fact, the product label says maples are sensitive to this product, so we would not recommend using Florel on maple trees.

  • Asked by David from San Juan Capistrano
    09/28/2019
    Q
    When do I spray Monterey Florel Brand Growth Regulator on two huge ficus nitida trees that drop berries?
    Any treatment says to spray when flowering....I never see them flowering, only producing more berries. When is the best time to spray to prevent berries?
    A

    Monterey Florel Brand Growth Regulator must be applied before fruit set for best results, and this is usually done when the plant is in mid- to full- bloom. If there is always fruit on the trees, then you may need to prune them back and then apply as the tree is regrowing and before that fruit set. We also recommend contacting a Master Gardener in your area for the best timing and care for this plant in your area.
