Can anyone help save my plants?!

[Falcon1]

Please help, I don't know what I'm doing wrong! The star jasmine was planted last year and is one of two plants. The other one is fine, so don't know what's happened with this one!

The pink azelia is only a couple of weeks old and is dying already!

The pansies are also only a couple of weeks old.

I'm gently watering every few days.

Any tips greatly appreciated!

I've had quite a bit of trouble this year, it's been too dry. It's possible the jasmine didn't like the sun position or soil type. Pansies are in any case not very long lasting, I wouldn't expect them to go that much longer. You could try enriching your soil with manure or changing your watering regime. I've had to put the sprinkler on.

It's very dry - I'd up the watering.

Should there be a photo showing their condition??

Depending on where you are I'd up the watering to daily, and be generous with it.

Azalea’s like ericaceous compost and rain water if possible.
Monty Don recommends a good drenching once a week.

Could the soil have been treated with a long acting herbicide at any point?

like others are hinting at, water sometimes runs off the top of the soil and never soaks into the soil and reaches the roots. is the soil loose enough for the water to soak deep down?

Thanks everyone, I'll start watering daily. I hope that rescues some of them at least!

Forget about "gently watering". You need two gallons per square yard.

Yes, I think you'll be under-watering. I remember emptying a 10 litre watering can into a pot, and was shocked to find that it had only penetrated the top inch of compost.
