Pull off old flower heads to prevent seeds forming. This will make more buds and reduce self seeding. Fortunately, if you don’t want to grow nasturtiums the following year in the same ground, the seedlings, with their round leaves are very easily identifiable.
Sometimes it is necessary to cut back the stem tips if they begin to take over.
Very easy to germinate, and will easily self seed
Sow direct into a well drained sunny position
Sow direct, nasturtium enjoys a sunny well drained position.
Some varieties are dwarf, some climb and some just creep along the ground and need room to spread
Nasturtium makes many flowers so there are always spare to pick for a vase. Pick when fully open
The flowers are edible and used in salad (watch out for tiny black but harmless flower beetles!)
The seeds can be pickled and used as an alternative to capers
Many seeds are produced and can be collected as they ripen from light green to beige. Pick the seeds into a paper bag and continue to dry in a warm airy place.
These estimates for how long Nasturtium takes to sprout, grow and harvest are from real observations from real gardeners, right around the world.
