I realize you mentioned you have them in different areas, so what I've found may not apply to the problem you're having. I've noticed I have better success with them in full shade. I have some in a very shaded spot with beautiful foliage and flowers and others in full/part sun that are yellowing and drying out.

Mine are yellowing too. They have been blooming great for me but now they look like they are going to die. I suppose I could move the basket and see if that helps.

I try not to fertilize often. They are in a hanging basket this year. Some are in more shade some are in more sun it really does not matter they are all turning yellow.
I only water them when they feel dry. In this heat does not take long.

What am I doing wrong??

See bold items. Nasties like to be ignored and in poor conditions.

mine are doing really bad too! they are in hanging baskets, I did not fertilize them, they were getting some some some shade I just moved them to full sun to see how they do. I will only water occassionally, maybe that will help! I see others pics of theirs and they are beauties! don't understand the difference!

I am finding that the ones I have in afternoon shade are doing much better than the ones in full sun. Also I water them very little. Most of the information on them says to plant them in full sun. I think it makes a difference how hot it gets. Apparently they like cooler temps.

Several people told me not to pay much attention to the nasturtiums, but mine are planted in a bed with rich soil and full hot sun until around 4PM. I do water them LOTS, as they are close to some other plants that need quite a bit of water. They are winter sown and are looking great. The foliage and the blooms are vibrant and healthy. They have been blooming for just over a month now, so they may be getting ready to stop blooming, start turning yellow and looking bad. I sure hope not.

Mine were doing great in our cool, cloudy, rainy spring. After several hot sunny days, the leaves are yellowing and curling up. They have started to bloom though. The foliage was awsome, leaves bigger than my hand! I might try feeding them.

It's my first time to grow nasturtiums as well. I have some in continues full sun location and some receives sun until 1pm. I don't see any difference between the 2 groups although the one in full sun droops first after 3-4 days without water.

The variety I have is empress of india. It's got dark green foliage. There was one nasturtium plant that got mixed. It has lighter green foliage. It's in the full sun area as well and beside the other dark green nasties. It's not as strong as the others.

I have some yellow leaves on my Black Velvet nasties too. I just thought it was that the oldest leaves were dying off. They are in a container that was filled with the type of potting soil that has ferts mixed in. The flowers are kind of small, but I love the color. They get morning sun only and seem to be doing ok, except for the old leaves yellowing. Is that normal, or is the whole plant going to die?

Remember, foliage on any plant can yellow from either too much or too little water. Mine look *nasty* with yellow leaves, too, and I'm certain that it's from too much water. The soil never gets a chance to drain and dry before the next rain arrives.

Generally, my nasties do better with some feeding and occasional watering and afternoon shade. That benign neglect thing doesn't hold true for me.

This weather is so bizarre. We'll get hot humid days followed by cold days with monsoon rain. The past 2 days have been cold, cloudy, and windy with highs of 68-70. A rain shower every few hours keeps everything wet. I've only watered my plants once this year, our one hot humid week with no rain. I never remember a June like this year. I don't know if my nasties will even survive.
