watering

Jacob’s ladders need to be kept moist during active growth, but not over-watered. Water every 1-2 weeks during spring and summer when soil is dry. During the winter, water when soil is dry (1-2 times a month). Always water thoroughly, so that water runs out of the drain holes in the pot. Regular monitoring of soil moisture is recommended to avoid over or under watering. After watering the soil, let the excess water drain from the pot.

sunlight

Jacob's Ladder (Polemonium 'Lace Towers') is a flowering perennial with delicate blue flowers that thrive in full sun. This plant species prefers to receive 6 or more hours of direct sunlight each day. It will tolerate some shade, however, its flowering will likely not be as prolific. For an optimal display of blooms, it’s best to plant Jacob's Ladder in a spot where it receives morning sunlight and some shade in the afternoon to protect it during the hottest portion of the day.

pruning

Jacob's ladder (Polemonium 'Lace Towers') is a hardy, deciduous perennial with deep green frilly foliage and clusters of beautiful, fragrant blue flowers. Pruning should be done annually to encourage new growth. In general, pruning should take place in late winter/early spring when the plant is still dormant and before any new growth begins to emerge. Remove only the dead or damaged growth, such as leaves and stems that are broken or blackened. Prune all the branches back by up to 1-third of their original height. This will help to create a more compact plant and promote more flowering. Also remove any diseased or damaged foliage. Finally, thin out the leaves, so that air can circulate around them to prevent disease and promote healthy growth.
