...So, if you want more butterflies, plant more native trees.
I planted both hackberry and spicebush on my property this year to increase the odds of retaining a population of - hackberry and spicebush butterflies.
I ordered "bare rooted" whips through a mail order company in Michigan. If they take well, I will be forthcoming with the company's name. Meanwhile, when you plan to purchase plants- it is best to get them from a region as cold or colder than your home area. Don't be buying South Carolina plants, and then wondering why they failed to thrive in Ohio.
I used a spade to slice a vertical trough in which to place the roots. Don't plant trees too shallow or too deep. Figure out where the 'bulge" is just above the roots- and get that ground level.
The little ones are hard to see at this stage, so I mark them with a stake (makes it easier for the rabbits to find them!) ...
For the few minutes I invested today- I can look forward to many years of enjoying the berries and butterflies!
