🌱✗ Tested and false“You can't transplant parsley — it hates root disturbance”
Parsley does have a taproot, but sowing into modules and transplanting the whole rootball without disturbance solves it. The problem is bare-root transplanting, not transplanting as a method.
What to do: Sow into modules or small pots and transplant the intact rootball into its final position. Do not try to lift and move established plants from open ground.

“Parsley needs full sun or it won't grow”
Parsley can be grown in full sun or partial shade. It is more shade-tolerant than most herbs and a position with afternoon shade helps prevent bolting in summer.
What to do: Give parsley a spot in partial shade if you have it, particularly in the afternoon. Full sun works but demands more consistent watering. The plant is more forgiving of light than of drought.

“Parsley runs to seed in its second year — pull the whole plant out and start again”
Parsley is a biennial and does flower in its second year, but you do not have to pull it. Cut the flower stalk as soon as it appears and the plant will keep producing leaves for several more months. Let one plant flower and you get free seed for next year.
What to do: Cut the flowering stem low as soon as you see it. The plant will redirect energy to leaves for another season. Let one or two plants run to seed and collect the seed once dry.
In Scotland: Parsley flowering in a Scottish spring often coincides with a cold, wet spell. Cutting the flower stem early keeps the plant in leaf production through the summer.

“Pour boiling water over parsley seed to make it germinate”
Parsley is famously slow to germinate, and the boiling-water trick circulates as a remedy. Soaking seed in warm water overnight before sowing is advised, a milder version of the same idea. The boiling-water claim itself is untested by our institutional sources.
Our read Soaking in warm water is low-risk and well-supported. Boiling water is a gamble: it may crack the seed coat or it may cook the embryo. Use warm tap water and control what you can.
What to do: Soak parsley seed in warm water overnight, then sow into warm soil. Cover with a cloche or fleece to hold warmth and moisture. Expect two to four weeks for germination regardless of method.

“Flat-leaf parsley has much more flavour than curly parsley”
Flat-leaf parsley does have a stronger, more robust flavour, and most cooks prefer it. Flat-leaf is generally regarded as the preferred culinary type.
What to do: Grow the type you like. Curly parsley is hardier and stands up to a Scottish winter better than flat-leaf, and its texture makes it the better garnish.
In Scotland: Curly parsley's hardiness gives it an edge here: it survives a Scottish winter more reliably than flat-leaf and gives fresh leaves when little else is growing.
