Growing Nasturtium From Seed?
- Sow seeds direct into borders where they are to grow in a prepared seedbed with a fine tilth. Alternatively, grow in tray cells for transplanting into containers. If growing in a propagator use a reputable peat-free compost.
- Nasturtiums like a nice sunny position but also can take partial shade, this gives options when citing in the garden. The plants will germinate and grow quickly. A Liquid feed of Seaweed extract as they start to grow will make for a strong, robust plant. It acts as a tonic and will aid resistance to pest and disease. Maintain moisture when plants are young. These plants will grow in low fertile soils .
- Keep free of weeds by gently hoeing or hand weeding around the plants as their stems are tender. Nasturtiums make great groundcover and will help suppress weeds as they increase in size
- Pick off dead heads if time allows although not fundamental, trim back foliage if the plant becomes too large or scruffy. The flowers as well as being edible can also be used as cut flowers
- A Potash feed as the plants go into flower is a good idea but just the one as best to avoid too much fertiliser as soil that is too rich may cause the plant produces masses of leaves at the expense of flowers
Great for kids, a good starter plant to give them the gardening bug. A couple of Nasturtiums filled hanging baskets either side of the patio doors is a sight to behold. To add to its talents grow it as an allotment bed edging as it makes a great companion plant, planted around beans will help deter Aphids. Nasturtiums are superb for wildlife and garden predators like Ladybirds and pollinators.
How To Germinate Nasturtium Seeds
Nasturtium seeds should germinate within 10 to 14 days. As the seedlings develop thin them in stages to achieve the final spacing of 25cm apart. Alternatively, for hanging baskets and containers, sow in a greenhouse or on a windowsill and acclimatise to conditions before planting outside.
