Difficulties or problems when growing: ?
Planting season – When to plant: Spring as annual or in hardiness zone 6-8, spring to summer in hardiness zone 9-10a, spring to autumn in hardiness zone 10b and planting all year but better not in the summer in hardiness zone 11
How to plant: Dig a hole bigger than the root ball at least 50-150% bigger, if it’s heavy soil make bigger hole and add the light soil to make the drainage better, add organic matter, dead leaves, compost and humus.
Pests and diseases: Powdery mildew, slugs, mealy bugs
Pruning season: All year

Size of the plant: 30-50 cm, 12-20 inches
Growth speed in optimal condition: Fast growing / Medium growing
Water requirement: Average amount of water, can grow in small amount of water and the plant can survive drought but better to give the plant regularly water
Light conditions in optimal condition for growing: Full Sun, can grow in less than full sun but will bloom less
Is it possible to grow indoor as houseplant? No
Growing is also possible in a pots, planter, flowerpot, containers: Yes, start with pots that bigger than the root ball at least 100-200%, possible to grow the plant in pot of 10-15L (2.5-4 gallons), use potting mix or peat soil with perlite and mix it with humus and organic matter, if use bottom for the pot let the bottom of the pot fill in water but dry in the same day, drainage of the soil is important and need to make enough holes, when the plant grow in the same container few year need to consider to switch the soil usually potting mix or other kind of soil lose their viability and also the soil become heavier and prevent the drainage of the soil

How to plant: Better to use potting mix or even better peat soil with mix of vermiculite
Planting spacing: 30*40cm (12*16 inches)
Depth of Sowing: Better to put the seeds on the soil and another option to cover lightly 2mm (0.01 inch)

Watering requires for Seeds: Small amount of water to average amount of water, don’t let it dry and don’t overwater, keep the soil lightly moist, and when the seeds not cover need to keep humidity by spray water
Germination time: 2-4 weeks
Condition of seedling: Full sun and light moist soil and when after the 4th leaf reduce the moist and let it almost dry between watering
