How long do nasturtium flowers last?

A Refresher on Annuals

Remember that nasturtium is an annual, which means it completes its life cycle in one year. Therefore, if you planted your flowers in the spring, they will likely produce seeds in late summer or early fall, and die off with the first frost. Don't worry if this happens.

How high will nasturtiums climb?

Many nasturtium varieties grow in a long, vining habit, climbing to heights of 8 or 10 feet when given support or trailing along the ground when support is unavailable. These plants are good choices for arbors, tall trellises or along fences.

Do nasturtiums like sun or shade?

Nasturtiums do well in poorer soils and do not typically need extra fertilizer (unless your soil is extremely poor). Too much nitrogen will encourage more foliage than flowers. Soil should be well-draining. Plant nasturtiums in full sun (6–8 hours of sunlight) for the best results.

Do nasturtiums need lots of water?

Nasturtiums do benefit from regular irrigation. Water given once or twice weekly, when the top 1 inch of soil begins to dry, is usually sufficient. Provide enough water to moisten the soil to a 6-inch depth. Although it's not necessary to prune nasturtiums, they may spread and become invasive if allowed to set seed.
