EDITOR’S NOTE: This story has been updated to reflect that the sightings were in Virginia.
Spotted Lanternfly update! I just spoke with Virginia Tech entomologist Eric Day about the confirmed sightings of this invasive insect in Frederick County, Virginia.
He explained that their favorite plants in the area 鈥� the so-called 鈥淭ree of Heaven鈥� 鈥� have either been eradicated or treated with a systemic insecticide to keep the lanternfly numbers as low as possible. Which is ecologically fine, he explains, as the Tree of Heaven is not pollinated by bees, so no collateral damage there.
The same cannot be said of another method of control being actively promoted. Many garden centers are selling large rolls of sticky paper to wrap around trees, but these sticky sheets have trapped a lot of wanted creatures as well 鈥� bats, birds and pollinating bees. So don鈥檛 jump on that bandwagon. (A wildlife rehab facility just sent me a photo of a young red tailed hawk trapped in the stuff 鈥� chilling!)
Right now, just look for and destroy their egg cases (which look like splattered mud) and report all sightings.
Please of the spotted lanternfly in Virginia, Maryland and D.C. The site is technically for Virginia, but D.C. or Maryland findings will be sent to the appropriate state or federal agency for their area.

Deflower your tomatoes!
October is now 鈥渢he cruelest month,鈥� because it鈥檚 my sad duty to tell you that the summer crop season is officially over.
- Pull off any new flowers that form on your peppers, tomatoes, zukes, cukes and such 鈥� there just isn鈥檛 enough time left for them to become viable fruits before frost comes a callin鈥�.
- Maybe even pull off baby fruits to try and coax bigger ones to fully ripen.
- The shorter hours of daylight even make it a good idea to just start bringing green tomatoes and peppers inside; just let them sit out at room temperature, and fully grown fruits will slowly color up.
- Go all the way and pull up the old spent plants, and you鈥檒l have room for pansies and salad greens 鈥� both of which love growing in the cool air of fall.
How much rain have we had, garlic lovers? I got moss growing on the north side of my leg!
Have you planted your garlic yet? The best time to do so is considered to be 鈥渢he first day the kids go back to school.鈥� Well, those kids have been failing tests for a month now, and my garlic is still waiting to go in the ground! Why? Wet soil.
Garlic cloves want water, of course. But like most plants, they want to dry out in between waterings. And it鈥檚 just asking for neck rot and other problems if you plant them in sodden soil to begin with. (If I had planted my poor cloves at the 鈥渃orrect鈥� time, they would have been drenched with 127 inches of rain by now!)
So I鈥檓 still waiting until the ground is nice and dry to plant my garlic. If you have also been waiting 鈥� or procrastinating, which is the professional form of waiting 鈥� don鈥檛 worry. There鈥檚 still time. Single cloves planted soon will still develop into nice full heads by the end of June next season. But can we get that dry stretch before Halloween?!
Please?
Don鈥檛 prune roses now 鈥� unless you don鈥檛 like them
Lynn in Rockville, Maryland, writes: 鈥淢y roses have gotten really tall and gangly. And tall. Is this a good time to prune them?鈥�
No, Lynn. It is pretty close to the worst time. Pruning stimulates new growth. Pruning in the fall stimulates that growth just as the plants are trying to go dormant, sending their energy down into their root systems in advance of winter. Pruning now disrupts this natural move to dormancy and can greatly stress the plants in question.
Even worse? Pruning next month, when that lush new growth could freeze solid when a really cold night follows a mild day.
The best time to prune roses and other summer bloomers is in the spring, about two weeks after new growth appears.
The dead of winter is also fine, but don鈥檛 prune too low down on the plants or you鈥檒l expose the crowns to severe winter injury. Leave at least a foot or two standing.
How to eat Fig Newtons
Lynn in Rockville writes: 鈥淚 have a fig tree whose main branches died last winter. It grew back up from the ground into a huge plant, but it put out its figs very late in the season. There are numerous small green ones that I don鈥檛 think will have enough time to ripen. How do I prepare the tree for a good harvest next season?鈥�
Figs are 鈥渉alf-hardy鈥� in our region, Lynn. Left unprotected, the top growth will often die back over winter while the roots survive. But without some top growth to get things started, there isn鈥檛 time for the plant to produce enough biomass for it to then produce a ripe crop of figs.
Fig-perfect directions:
- Do not prune the tree.
- Drive some stakes into the ground and wrap burlap around the stakes 鈥� not around the actual tree.
- In the spring, remove the burlap, trim back any dead wood and get ready to make Fig Newtons.
