1. Choosing the Right Location

Nasturtiums prefer full sun but can tolerate partial shade. Choose a location that gets at least six hours of sunlight per day. Make sure the soil is well-draining and fertile.

Soil Preparation:

If your soil is heavy clay or sandy, amend it with compost or other organic matter. This will improve drainage and nutrient content.

2. Sowing the Seeds

Sow nasturtium seeds directly into the ground after the last frost date in your area. The seeds should be planted 1/2 inch deep and 8-12 inches apart. Water thoroughly after planting.

Seed Treatment:

Some gardeners recommend soaking the seeds in water overnight before planting to help speed up germination.

3. Watering and Fertilizing

Keep the soil consistently moist but not waterlogged. Fertilize once a month with a balanced fertilizer.

Types of Fertilizers:

You can use either an organic or synthetic fertilizer. Organic options include blood meal or fish emuon, while synthetic options include all-purpose granular fertilizers.

4. Mulching

Mulching can help retain moisture in the soil and suppress weeds. Use a layer of organic mulch such as straw, leaves, or grass clippings.

Types of Mulches:

There are many types of mulches available, including wood chips, shredded bark, and cocoa bean hulls. Choose one that fits your garden's needs.

5. Deadheading

Deadheading, or removing spent flowers, will encourage the plant to produce more blooms. It also prevents the plant from setting seed and becoming leggy.

When to Deadhead:

Deadhead as soon as the flowers to fade. This will encourage the plant to put its energy into producing new blooms rather than seeds.

6. Pests and Diseases

Nasturtiums are relatively pest-free but can be susceptible to aphids and whiteflies. Keep an eye out for these pests and treat them with insecticidal soap if necessary.

Natural Pest Control:

You can also use natural pest control methods such as companion planting or introducing ladybugs and lacewings to your garden.

7. Pruning

Pruning can help keep nasturtiums compact and prevent them from becoming too leggy. Pinch back the tips of the stems to encourage branching.

When to Prune:

Prune throughout the growing season as needed, but avoid cutting back more than one-third of the plant at once.

8. Propagation

Nasturtiums can be easily propagated by taking stem cuttings or dividing the plants in the spring.

How to Divide:

Dig up the plant and separate it into smaller sections, making sure each section has roots attached. Replant in well-draining soil.
