How do I prepare my soil for vegetables and herbs?

Turn your soil over to a depth of 12″-15″. For each 100 square feet , spread evenly over the area 6 bags of Organo Omni Mulch, (1.5 cu. ft bag) 2 lbs. of Soil Sulphur, and 2.5 lbs. (3 tablespoons/4 square feet) of Osmocote Vegetable and Bedding Slow Release Food. Mix thoroughly into the top 12″-15″, turning the soil over at least twice.Back to Top

Can I grow vegetables and herbs in containers?

Yes, providing that you have a large enough container for what you plan to grow, and your container has a drain hole. Some vegetables lend themselves better to container growing, such as Sweet 100 and pear tomatoes, peppers, and lettuce varieties. Be prepared to provide support for vining vegetables, or varieties that are large and bushy. All herbs do well in containers. When planting, use Black Gold Potting Soil, and sprinkle about 4 tablespoons of Osmocote (18″ pot) at a depth of about 12″.Back to Top

Where should I plant my herbs and vegetables?

Vegetables and herbs should be planted in an area that receives sun all morning, with shade in the afternoon. This is not as crucial for fall crops, but in the summer, it will be necessary to provide protection from our hot afternoon sun.Back to Top

How should I feed my herbs and vegetables?

If you did not add fertilizer when preparing your soil, you can apply 4 teaspoons of Osmocote under each 4″ transplant. It will feed your plants slowly over a period of 3-4 weeks. If planting from seed, you can fertilize with a water soluble fertilize, such as Growmore All Seasons Plant Food, after the first set of leaves has appeared. For established vegetables and herbs, you may consider feeding with El Toro Flower and Vegetable Food, containing sulphur and iron. Back to Top

I love garden grown tomatoes. Which varieties do you recommend for Tucson?

Tomato varieties that do well in Tucson include Celebrity, Early Girl, Sunmaster, Cherry tomatoes, Pear tomatoes, Roma, and Sweet 100’s. The summer growing season for tomatoes is pretty short, as the fruit will not set once the temperatures go into the 90s, so it is best to get your plants in the ground late February to mid March. You can also cut back your tomato plant in August, for a second harvest in the fall. You may also consider planting tomato plants in summer for fall harvest. Back to Top

Some of my tomatoes have a black, flattened spot on the bottom of them. What’s wrong?

This is an indication of blossom end rot, which is caused when the plant is watered erratically, too lightly, or infrequently. It is commonly thought that the plant is suffering from a calcium deficiency when this happens. The best thing to do in this situation is to correct how you are watering.Back to Top

I found a large green caterpillar in my tomato plant. Is it harmful to the plant?

The caterpillar in question is a tomato horn worm, and it can do quite a bit of damage to your plant. Check the undersides of the foliage, and remove any of these pests that you come across. Back to Top

What can I use to get rid of aphids on my vegetables and herbs?

You can try spraying them off with a hard blast of water. You can also spray your plants with a soapy solution of 2 tablespoons liquid soap detergent to 1 gallon of water. The safest insecticidal spray to use is one made of Pyrethrin, such as Fertilome Quik-Kill Insect Spray Back to Top

There are holes on the leaves of some of my vegetables. What is causing this?

This is an indication of caterpillars. We recommend spraying your plant with Greenlight BT Worm Killer, which contains BT (Bacillus thuringiensis), a bacteria that kills caterpillars. Be sure to spray the undersides of the foliage. Do not spray when the temperature goes above 90 degrees, at the bacteria dies at high temperatures. Back to Top
