strike rate for Ranunculus
recent years I have had very low strike rates with ranunculus
sometimes none have come up at all! This year, my success rate looks
like it will be only about 30 per cent. I usually plant them in
April, claws pointing downwards, after soaking them in water for
a few hours. I plant them at about 4-5 cm deep, either in a planter
box or in pots. What am I doing wrong?
seems you are doing everything correctly by soaking the "claws"
and planting them 4-5 cm deep. It is very important that the "claws"
be kept moist at all times once planted. Plant ranunculus in full

into garden soil or compost, as over time they compact down and
do not give enough aeration to the roots.
Once potted, place the
pot in the shade until they sprout keep the potting mix moist,
but not wet. When the claws sprout move them into full sun and keep
Ranunculus are frost
tender, so plant after frosts have passed.
Slugs and snails enjoy
new shoots; protect with Blitzem or Baysol.
