PEST CONTROL, 
​​​

SALES, and JULY BLOOMS!!

PEST CONTROL

This is the season for pest problems (diseases, insects, fungus) and here at Harlequin’s Gardens we have products that have been proven successful for combating them in effective and environmentally safe ways!  Below are some of our favorite pest control products; come on in to see our full range of products, some of which are on sale at 50% off through Sunday, July 1! 

While you’re here, please utilize our reference library and knowledgeable staff to help with your plant and pest identification needs.    
  • When bringing a plant identification sample, please bring a sizable sample including numerous leaves, flowers, buds, etc.
  • When bringing a pest sample, again bring in a sizable plant sample and several bugs, eggs, etc.
  • We request that you bring all samples in clear plastic bags to avoid contamination of our plant stock.  Thank you!

NEEM OIL from INDIA

Pure, cold press with active ingredient Azadirachtin, which is approved by the EPA.  Neem controls, stops feeding of and/or repels Aphids, Leafhoppers, Scale, Leafminers, Beetles, Spider Mites, Mealy Bugs, Thrips, Caterpillars, Weevils, Whitefly, Grasshoppers and fungal disease like Powdery Mildew.  It is not harmful to humans, animals, beneficial insects or the environment (not good over water with fish). 

Neem must be sprayed directly on pests to be effective for killing; it prevents molting and stops feeding, and works as a repellent. Spray in the early morning or evening.  Neem oil solidifies at 50˚, so thaw it in a warm water bath before mixing.  Then, mix it with one quart of warm water and ¼ teaspoon of mild dish soap, and shake occasionally to emulsify.  For very tough pests try 2 teaspoons per quart with ½ teaspoon soap (test on small area first).  Neem requires some care to use but is safe and very useful.

GREEN CURE

Organic protection & correction of fungus diseases. It has been tested commercially for over 9 years. This alternative to toxic fungicides has proved effective against powdery mildew, blackspot, rust & others. This product is perfectly safe for use on vegetables.  Local rosarians swear by it!  

VEGGIE PHARM

Amazingly effective not only for aphids and mites, but even for blister beetles and potato beetles, that devour clematis, mirabilis, and anemome!  Veggie Pharm also acts as a repellent for insects and small animals.

JAPANESE BEETLE BAIT

Sadly Japanese Beetles have become an annual problem in Boulder and neighboring counties. We are now carrying Safer® Brand Replacement Bait to help you with the Japanese Beetle Battle.  This product uses a food and sex attractant to lure insects into the trap and disrupt the mating cycle of destructive Japanese Beetles. There are no sprays and has no mess, and under ordinary weather conditions, this bait should last about 12 weeks.

Trap Placement, Application Rate and Use:

  • Place traps as beetles emerge (late June in Colorado)
  • Place traps on the generally upwind side of vegetable gardens, flower gardens, ornamental shrub planting and other outside landscape planting attached by the beetles. Apply traps at the rate of one trap per 50 linear feet along two sides of plant perimeters. For example, if the site is 1-50 linear feet, place only one trap on each of the two sides. If the site is 51-100 linear feet, place two traps on each of the two sides, etc. Do not enclose the treated site with traps.
  • Place traps in sunny areas 3 to 5 feet above the ground.
  • Place traps at least 10 feet away from the planting as they may attract beetles to foliage if placed closer
  • Replace traps when full. If trap catches decline and beetles are still present, replace bait pack. Remove traps from site when beetles are no longer present.
