Many houseplants thrive outside during summer, growing well with the brighter light intensity, but it will soon be time to bring them back indoors. Most plants grown as houseplants originated in the tropics, so nighttime temperatures dipping into the 40’s and 50’s F mean it’s time to bring them inside. Click here for the complete article.

For tiny green tomatoes developing on plants now, gardeners might wonder if this fruit will mature before frost.

Fruit development depends on tomato variety, day and nighttime temperatures, and amount of sunlight received between now and frost. And we don’t know when the first frost will be.

This year the National Garden Bureau features Lantana as its annual flower of the year. In the 18th century, lantana was a popular greenhouse plant in Europe and breeding efforts were extensive, resulting in hundreds of available selections. The most commonly available species, Lantana camara, is a tender plant winter hardy to zone 8. Although lantana is not winterhardy in Nebraska, it makes a tough, colorful summer annual for containers or ground beds.
