Someone please help, I spent an arm and a leg and watched tons of videos about the roses I bought to plant and after a week and a half the leaves are very discolored, what can I do to help my babies ? This is a David Austin Climbing Rose

How much have you been watering? How hot has it been? Have you sprayed them with anything?
Have you fertilized them at all?

It looks like some kind of water stress. But, both too much AND too little water can cause leaves to yellow.

Also those crispy edges look like they might be from sunburn. If it has been very sunny and hot you may need to provide some kind of shade for them. Even a lawn chair placed over them during the hottest part of the day can help.

Spray burn can also cause those crispy brown edges. NEVER spray on a sunny day when the temp is above 75 degrees. Wait for a cool cloudy day to use any types of sprays.

Newly planted roses may lack small feeder roots or have very tender ones. Too much fertilizer early on can burn those roots easily causing the plant distress. It is recommended to wait until after the first bloom cycle is over to fertilize newly planted roses.

I water every 2-3 days. I put my finger as far into the soil as it will go, about 3 in. And if the soil is dry, I water. We planted with rose garden soil from miracle grow. They were planted 2 weeks ago.

I think perhaps there is more than just one problem going on here. I'm thinking a bit of transplant shock, too much hot sun that the plant wasn't prepared for and maybe something biological that hitched a ride from wherever you bought it from. Roses are big "Divas" by nature and sometimes if they're not happy about something they throw a little hissy fit. I would trim out the yellow/brown leaves, check closely for bugs and then fertilize it with a fish & seaweed liquid type fertilizer,..... also give it some shade from the hot afternoon sun.

I would give it more water. My rule of thumb is if the soil is dry an inch down water it. Rose need 1 to 1 1/2 inches of water per week. Get a rain gauge so you can see how much rain it's getting and add water from there. Newly planted roses always need extra water to grow new roots to get established. You can add any kind of organics to the soil but NO chemical fertilizers until it improves and you see new growth starting.

Sorry GardenLight but I hate when people call roses divas. They are not. They are no harder to grow than any other perennial shrub is. They need the correct sun exposure, adequate water, a good pruning once a year and some fertilizer once in a while. You would do the same for hydrangeas, azaleas, rhodys or any other kind of perennial. Please don't continue the myth that roses are hard to grow!
