Building shade and not deep forest kind of shade.. may be

What kind of shade do we consider this bed?

from yard:

from porch:

I'm putting some David Austin's here.

I'm a little nervous because I think they are already needy.

Have you observed the area through the day? Reason I ask is that I thought one of my planting bed was in all day shade. I even started a post asking if any rose will work in that area. Found out the front area, up to around 4' ft, gets full direct sun starting from around 12:30PM through atleast 4:30PM, if not a bit more. I was about to start a post looking for recommendations, which I plan to do, and dont want to hijack your thread.

Observe the area every 30 min to 1 hr and see how the shade shifts around. Some areas in my yard get more shade than I thought, and some less. I wish there was an easy way to map it. also, for some of these borderline areas, trial and error is probably the only way to go.

Hijack away, I certainly don't mind.

It gets a couple of hours of sun in the morning (definitely not 6), but I don't know if that plus whatever type of shade this is would be enough.

Interested to see how the Austins do in that area. I have Jude in a less than optimal situation, he does get morning sun for a few hours, then a bit of dappled, then a couple more. He is not doing great, I have seen less than 10 blooms in 3 years. Couple of other Austins in the same bed have not bloomed in 3 years. My Don Juan which in the previous house, same area, would blooms its head off all year, maybe couple of blooms. A few other just died there, they do get water from the sprinkler. This year, I am going to pay extra attention to them and see if I can coax them to do something. If not, i will move Jude and probably toss the rest and try a couple of super shade tolerant climbers.

And how the sun moves from March to June and July! I have a few spots where sun behaves as full sun instead of part sun only in summer

If I have to ask that question, it's probably not enough sun for a rose to do well here, lol! Seriously though I find that without enough sunlight I have more blackspot issues with some roses. For example my front garden bed is in full shade until noon, after that baking sun until sunset. With the bs we have here that really effects some roses. And as others pointed out the degree of sunlight changes week to week during the season. And all my leafy trees & shrubs have to be accounted for when it comes to casting more shade.

I've mapped many areas but you have to do it every couple of hours and then across several weeks because as the sun gets higher and the trees leaf out things look totally different. Most of our forecasts are for cloudy, partly cloudy and partly sunny when it isn't just all out rain. So add that to shade and nothing performs well - it may grow and look healthy but no flowers. Now that I've said that I am planting my David Austin garden in a questionable area and it will probably be a loss. Even those roses listed as shade tolerant will probably be unhappy. But nonetheless they will be going in the ground next week.

I suppose the sun in TX is different than sun in say Ontario....also difficult sometimes to find out what exactly. is causing less than optimal performance. I have found root competition to be a bigger problem than lack of sun. When the shade comes from buildings etc, plants do much better.

The other thing to consider is day length in different states and countries. Up here we have many more hours of sunlight per day in midsummer. Love those days were the sun sets at 9:00 pm!

Location does change things drastically, methinks. My garden, in Tuscany, Italy, with it's south-western exposure,is so brutally hot in summer that full sun is way too much for some roses,and cloudy days are very rare. I am praying and hoping that it will start to rain a bit here; it's only March but it's as warm as if it were May,and every day is sunny. And I totally dread the days when the sun sets so late, and the days seem endless; it's just too much! It's exhausting! But HalloBlondie ,up in Canada, feels very different,because the whole climate is just so different. So if a rose is considered "shade tolerant" in cloudy England,I'm beginning to think that in my garden it would actually prefer shade. That said, mapping out a spot does sound like a good idea,though kind of hard to do,especially when the shade is provided by deciduous trees .
