I have this spot I thought would be perfect to Astilbes. I love Astilbes. They want half-shade, and the spot was right. I had old ones there in a corner, so I added 25 more last April.
I have a grass-weed that takes constant pulling/digging. I get rid of it in one spot and it is spreading in another. One day I will get the last one (making progress actually). So it was overgrown where I planted new Astilbes in April. They had to go...
And I did get mostly roots pulled up with the grass-tops! A full bushel basket of them. It looks much better now.
The spot I have the Astilbes in is mostly shaded. But it gets serious late afternoon sun, and they don't like that. At least yesterday after I pulled up the 16" tall grasses, they had some shade. After that, Mr Sun hit them hard and they wilted. But it was only for 2 hours. I hope they adjust. Otherwise, I will be moving them in the Fall (and I have a spot in mind). It depends on how well they do this year.
They looked better after some deep watering and with the landscaping flags removed...
The Baptisia will give them some shade soon.
I've been outside almost 4 hours per day for a few weeks now. It shows. I've never been so nearly caught up with gardening and yardwork before. Yay!
