I live in LA. So hot I had to bring my sunpation indoors.

Well, according to Gardening Know How, "Growing sunpatiens plants is very easy and low maintenance. The plants prefer well-draining soil that’s rich in organic material. They grow very well in both containers and garden beds, and they like full sun or partial shade.

For the first week or two after planting, they should be watered every day to get them established. After that, they need only moderate watering and can usually be revived from wilting with a good dose of water.

Sunpatiens companion plants are any colorful flowering plants that also enjoy full sun. When growing sunpatiens plants, especially if grouping with other plant varieties, it’s important to know how much space you are looking to fill in. Sunpatiens plants come in three size categories: compact, spreading, and vigorous.

Compact and spreading plants are both perfect for containers. (Compact plants stay small while the spreading ones fill out a hanging basket or pot spectacularly). Vigorous plants are best for garden beds, as they grow fast and fill out a space with bright color quickly and effectively."

Try using a saw or have the city trim them for you if they are too tall.

You can rejuvenate the plants and stimulate new, bushy growth by pruning them, cutting each main stem back by one-half to two-thirds. The SunPatiens respond to mid-season pruning by developing multiple new shoots on each pruned stem.
