GROW GROUP LESSON PELARGONIUM

Common Plant Name:  Geranium…which is actually a Pelargonium. True Geraniums are known as Cranesbills, which refers to the shape of the seedpod.

Botanical Name   Geraniaceae family- over 400 varieties- (perennial)  

How the plant recycles life  Commonly from cuttings (semi-ripe cuttings are best); using a root hormone to promote root  growth, usually takes about 4 weeks to develop.  

Also from seed; the seed pods with ‘curls’ act like a catapult to hurl ripened seeds away from parent.

Growth habits  Plants vary from upright to trailing. Plants are good in rock gardens, perennial gardens, or as small scale ground covers. Once established, pinching top will promote a bushier plant.

Nutrients required  Once established, organic fertilizer (slow release) 4-4-4…sprinkle on top, and work into soil & water well once per year.

Soil needs will grow in any soil as long as it is not water logged. Always plant in well drained.soil, adding vermiculite will help.

Bloom time  spring through fall.  Remove spent flowers to promote healthier plant and more blooms.

Shade/Sun exposure  requires 4-6 hours of full sun per day. Plant is heat tolerant.

Water needs  Most need constant moisture, but do not over-water.

Predators and Problems Caterpillars (tobacco bug worms), white flies and aphids

Propagated/germination date (today’s date)

Extra notes  Will not bloom if over-fertilized!

Planting notes   If propagated indoors, keep soil ‘moist’ and harden off before moving outdoors. Always begin with smaller container, work up (transplanting) to larger pot as plant grows and becomes established.

Tid-bit  Geraniums are a natural insect (primarily mosquito) repellent…making them a perfect in a window box!
