At your local home center store:

Foliar feed with Liquid Seaweed or Extreme Juice in the evening every 3 to 5 days. This allows the plants to have immediate access to all the nutrients all night long through the stomata of the leaf. You may also think about covering your tomatoes with row cover. This will protect from leaf hopper that can transfer many diseases. Studies have show that putting a red plastic mulch down (you can also use a red plastic table cloth) will increase tomato yields by 20%.

Use our Organic Weed Control sprayed directly onto the leaves of your weeds. This is basically a strong vinegar that will do the job without all the synthetic chemicals. Corn gluten meal is also a very good choice as a pre-emergent in your granite areas. It will prevent weed seeds from germinating.

Feed your lawn with Garden Guy Granules every 4 weeks. We also have our Extreme Weed and Feed product for your lawn. It is Corn Gluten based so it is an organic fertilizer but it also is a natural pre-emergent. It will not allow new weed seeds to germinate in your lawn.

  • 1 Gallon of Garden Guy 10% Vinegar
  • 3 tablespoons of orange oil (homemade or purchased as Zep’s Heavy Duty Citrus Degreaser (avail. at home center stores or any cleanser with D-Limonene)
  • 1 – 2 drops of Dr. Bronner’s Peppermint Soap (Whole Foods) or Dawn Dishwashing liquid
  • Put in plastic spray bottle, shake up and spray directly on anything you want to eliminate. DO NOT spray on anything you want to live!!! *When handling vinegar always wear protective eye wear, a mask and gloves.

The Suspects are beetles, caterpillars, crickets, grape leaf skeletonizer, grasshoppers or weevils. Use our Extreme Diatomaceous Earth for crawling insects. Our DE is food grade (not pool grade!) so it is safe to dust around your garden and even directly on your plants. The powder acts like millions of razor blades that cut the exoskeleton of an insect causing it to dehydrate and die. This is a great natural way to kill the pest and not harm your veggies. If you know you have caterpillars try Bacillus thuringiensis (sold at nurseries as Thuricide). It is a naturally occurring organism that will kill caterpillars from the inside out. Like DE it is not dangerous to pets or children.

Citrus like to be watered deeply for long periods of time and then allowed to dry out in between. Established citrus should be watered slowly for at least several hours every 10 days or so in the summer, 1-2x/month in the spring and fall, and often not at all in the winter if we get occasional rain. New citrus should be watered more often for the first year while getting established.

Don’t! Citrus are genetically large shrubs. Their branches hang down naturally, and that protects their thin bark from the hot summer sun. Also, trimming will expose new, tender growth to extreme hot temperatures in the summer and possible frost in the winter.

Valentines Day, Memorial Day, and Labor Day are rough estimates of proper times to fertilize. If you miss one of these dates, don’t worry. Citrus are pretty forgiving and you can fertilize at the next appropriate date. Use an all-purpose fertilizer and water it in deeply.

The curling is from an insect called Thrip. They don’t hurt the leaves or fruit. Don’t spray anything to kill the thrips. The insecticide will do more damage by killing beneficial insects. The thrips will go away on their own.

No. A well causes water to stay around the base of the trunk. The cells of the trunk should not stay wet. There is a fungus in the Phoenix area that is prolific in warm, moist conditions. Citrus are susceptible to this fungus, so by keeping the area around the base of the tree dry, you protect your citrus from the fungus. Make sure when you water citrus the water reaches the drip line of the trees. This is the perimeter where the outer branches hang. Under the drip line is where most of the feeder roots are that absorbs water and nutrients.
