Growing Climbing Nasturtium: Soil, Sunlight, Watering, and Care
Climbing nasturtiums are generally planted as annuals in areas with cold winters. However, in some mild climates, they can behave as short-lived perennials. In USDA hardiness zones 9-11, nasturtiums may survive the winter and return in the following growing season.
The flowers bloom from late spring until late summer, sometimes well into early fall.
Thrives in well-draining soil with moderate fertility
Climbing nasturtiums are plants that love to grow in soil that drains well. They don’t like their roots sitting in water for too long. So, choose a spot in your garden with loamy, well-draining soil. If the soil is too compact or heavy, you can amend the soil by adding some organic matter like compost or peat moss.
Climbing Nastirums Prefer full sun but can tolerate partial shade.
These vibrant climbers thrive under the warm rays of the sun. They prefer full sunlight exposure for flowering and developing lush foliage. However, if you have a partial shade area in your garden, don’t worry! Climbing nasturtiums are adaptable and can handle some shade as well.

Requires regular watering to keep the soil moist but not waterlogged
Giving them regular watering is essential to keep young plants and your climbing nasturtium happy and healthy. Make sure the soil stays moist but not soggy. You don’t want to drown these beauties! Aim for about an inch of water per week and adjust according to weather conditions.
Nasturtiums – Low-maintenance plant that is resistant to pests and diseases
One of the great things about climbing nasturtiums is that they are low-maintenance plants. They’re pretty hardy and resistant to common pests and diseases that plague other plants in your garden. This means less time spent worrying about pest control or disease management!

Training Climbing Nasturtium: Pruning and Support Methods
To promote healthy growth and abundant blooms in the summer garden, it is essential to train climbing nasturtiums by pruning and supporting these vibrant vines effectively.
Pinch back the growing tips – Encourage bushier growth in climbing nasturtiums by regularly pinching back the growing tips. This technique helps stimulate lateral branching, resulting in a fuller and more compact plant. Use your fingers or pruners to remove the topmost part of the stems.
Use trellises, fences, or arbors as support structures for Growing Climbing Nasturtium. Climbing nasturtiums require sturdy structures to climb upon. Install trellises, fences, or arbors near the base of the plants to provide them with vertical guidance. These structures help keep the vines upright and enhance their aesthetic appeal in your garden. We like adding a few climbing nasturtiums to our garden bed with bean trellises for a stunning look.

Avoid excessive pruning -While pruning promotes bushier growth, it’s important not to go overboard. These plants bloom on new growth, so excessive pruning can hinder flower production. Be mindful of striking a balance between encouraging branching and allowing sufficient new growth for blossoms.
Consider using biodegradable twine or plant ties for support– When securing climbing nasturtiums to their supports, consider using biodegradable twine or plant ties instead of plastic. These environmentally friendly alternatives will eventually break down naturally without causing harm to the environment.
Step By Step Instructions for Planting Climbing Nasturtiums
Here’s a concise step-by-step guide for planting climbing nasturtiums:
- Soak the seeds in water: Soak the seeds in water 24 hours before planting out to hasten the germination speed. The water helps soften the hard outer casing of the seed pod, making it easier for the seed to germinate.
- Choose a sunny location: Select a spot with full sun to part shade, as nasturtiums thrive in these conditions. Plant out after the last frost in your region.
- Prepare the soil: Nasturtiums prefer well-drained soil. Loosen the soil and add compost for better drainage and fertility.
- Plant seeds: Poke seeds to a 1-inch depth and about 6-12 inches apart in the soil.
- Water well: Water the seeds or seedlings thoroughly after planting, and keep the soil consistently moist but not waterlogged.
- Thin seedlings: As the seeds sprout, remove any weaker or excess seedlings that impede spacing and airflow.
- Provide support: As the nasturtiums grow, they will need support to climb. Install trellises or other structures for them to climb on.
- Mulch: Apply a layer of mulch to help retain soil moisture and suppress weeds.
- Maintain: Nasturtiums are relatively low-maintenance. Water when the soil feels dry and remove flowers when they are spent.
Note: If you are planting nasturtium seedlings, plant out after all frost risks. Carefully and gently remove the seedling from the pot and place it in a pre-dug hole. Be sure to press the soil around the transplant and water it well.
You can purchase seedlings at most greenhouses in the spring, but the purchase price is often higher than planting seeds. Nasturtium vines grow quickly and well from direct sowing, so we recommend it!
