“Neo-Nicotinoid Free” — What Does This Means”

Earlier this year several big box store and regional independent garden center chains announced that the plants they sell in 2016 will be “neonicotinoid-free”. Large regional nurseries and greenhouse operations are also jumping on-board the anti-neonic bandwagon. This means that pesticides containing the ingredient acetamiprid and imidacloprid are members of the neonicotinoid class, and are forbidden to […]

Asian Pears Becoming Very Popular

Whether home-grown or store bought, Asian pear (Pyrus pyrifolia) fruits ripen sweet and tasty on the tree (USDA hardiness zones 4-9). There are over 100 varieties available worldwide, many with difficult to pronounce. Investigate variety cold hardiness and winter chilling rating as some cultivars are hardier than others. Southern varieties require only 300- 600 hours of winter chilling temperatures […]

Unique Life Cycle Of Bumble Bees

  Bumble bees (Bombus spp.) are highly beneficial insects that pollinate native wildflowers, fruits, vegetables, and many agricultural crops. They’re large robust insects with an easily identifiable black and yellow hairy abdomen. Hundreds of branched hairs pick up and transfer pollen from flowers. About 50 species of bumble bees inhabit North America. They share some common traits […]

Beware! Yellow Jackets

  Most humans fear and hate yellow jackets. They are actually wasps and important predators of several harmful insects. They’re easily identified by their distinctive markings along their abdomen. They tend to dart about rapidly, in a side-to-side flight pattern. Female yellow jackets are the ones capable of stinging. Wasps (Vespula spp.) are not bees; they’re brightly colored […]

They are beneficial pollinators in the garden. Bees in the families Colletidae and Andrenidae represent the ground nesting […]

Growing Pear Trees Too Challenging For Southeast Gardeners?

  For many reasons growing pears in the Southeastern U.S. is very challenging. First, European (Pyrus communis) and Asian (P. pyrifera) pears are susceptible to fireblight (Erwinia amylovora). This bacterial disease is very difficult to manage. Two of the leading European pear varieties, ‘Bartlett’ and ‘Bosc’, are highly susceptible to fireblight. Varieties found to be fire […]

Key Points Whether To Grow Peaches

Peaches grow in other places besides Georgia, USA. A decade long period of mild winters in the Southern Appalachian region (USDA zones 6 and 7) have increased gardener confidence about growing peaches. Peaches (Prunus persica) tend to flower in early spring when the threat of spring frosts is still high. In many years spring frost may kill 80% of […]

Tree and Berry Fruit Pollination Chart

  A frequent question of newbie fruit gardeners is what will pollinate what. Do I need many varieties or can all be the same variety? The four common terms are used: Self-pollinated: transfer of pollen occurs within the same variety. Cross-pollinated: transfer of pollen occurs between two varieties. Self-unfruitful: low fruit set unless the blossoms […]

European vs Asian Pears

  Growing pears in the Southeastern U.S. is both challenging and rewarding. Both the European (Pyrus communis) and Asian (P. pyrifera) pears are susceptible to fireblight (Erwinia amylovora), a bacterial disease with no satisfactory cure. Two popular European pear varieties, ‘Bartlett’ and ‘Bosc’, are highly susceptible to fireblight. Varieties found to be fire blight resistant are: ‘Warren’, […]
