Revice Struggling Plants

Hi all, new to gardening and trying to figure out what I'm doing wrong and am hoping to get some advice. I have a few struggling plants and some growing nicely but have added the main 2 below.

Firstly, I have an Azalea Japonica which I planted with Ericaceous Soil. It was nice and pink when bought and was doing well until I added some Miracle Grow Capsules to the ground. They pink blossoms then started fading and wilting. I redug the plant, removed the capsules, replanted and then removed the wilting blossoms. I also scraped the branch and there is green so I am hoping it is not dead. Any advice on where to go from here?

Also have a rose tree that has fading blossoms and all the new blossoms are not very good and growing white instead of pink as original. I started removing the wilting roses so hope it helps but am struggling to see and signs of healthy roses growing.

Any advice on what I can do to save the plant? I also have another rose tree that was blooming very nicely when bought but also has needed deadheading due to wilting and discoloration of roses.

 

The Azalea leaves don't look too bad, one bit might have a problem, but could just be out of focus.
Azaleas don't flower continuously, they produce one flush of flowers in spring/early summer and then the spent flowers go brown and fall off. If it was in a pot and you planted it this spring that could have shortened the flowering period. If you water it during dry periods over the summer you should get flowers next spring, remember they tend to be deciduous so lose their leaves over winter.
Rose again foliage doesn't look too bad; do you know the name of the rose. Rose flowers only last a week or so and then lose the petals, deadheading is an ongoing job with roses.
Sometimes roses can change colur as the flower opens and ages.

 

Thank you very much Nigel. Very helpful information. Are there any flowering plants that are recommended that will flower throughout the summer as it looks like Azaleas flowering are very short lived?

Welcome, Danny. Your roses will bloom all summer with occasional spells between one flush and the next. Sweet Peas give a lovely summer-long display. Annuals will give you lots of flowers during the summer. You plant them in the late spring, they come into flower and provided you deadhead them they will likely continue blooming through to the first frost.

 

Thanks Jocko. I like the look of sweet peas. Are they evergreen? I prefer something that doesn't need replacing every year. I did buy some nice annuals, some of which are wilting slightly as well. When deadheading plants, do I need to remove just the flower bud or cut from the stalks?

 

Sweet peas just last the summer. When I deadhead I just nip back to the next split. Some roses have a mass of blooms so you are only nipping back a couple of inches. Some flowers you nip back quite a bit.
If your annuals are wilting they probably need watering. I have some larger annuals in hanging baskets and on sunny days they need watering every evening.
