per 14” hanging basket. If you are starting out with smaller plants they
should be pinched out at least twice so that the plant grows busy and
spreads to evenly fill out your basket or hanging planter – they can
tend to get a little leggy other wise.
Evolvulus loves the light and heat. So position your basket or
planter in full sun and watch it go. While Evolvulus will also thrives

Watering Your Hanging Planter

basket a light monthly application of a good water-soluble fertilizer to
keep your basket blooming.
As it is somewhat drought-tolerant, be careful you don’t overwater.
Blue Daze does not grow well in wet, soggy conditions, so good drainage
is an absolute must – and allow your hanging basket or planter to dry
out between waterings – especially in early spring when it can still get
cool at night.
Fertilizing & Feeding
We recommend applying a slow-release fertilizer upon planting. Like
most hanging baskets, with the watering draining away so do a lot of the
nutrients. Evolvulus really like to be feed and will reward you with
more and more blooms if you do so. So in addition to your slow release
fertilizer apply a balanced, water-soluble fertilizer each month using a
Tips on Caring for Your Plants
To prevent fungal spots, gently spray plants bi-weekly with a mixture
of 1 heaped teaspoons baking soda and just under half a tablespoon
horticultural oil per ¼ gallon of water. You can make this mixture up
every other week or do as we do and make a mix to last a month or more.
We keep ours in a good sized mister or spritzer. Make your initial mix
using warm water and ensure that the baking soda fully dissolves. Shake
well each time prior to spraying your hanging baskets or hanging
Over Wintering Your Basket or Planter
Blue Daze also makes a nice indoor plant in bright sunny areas of the
home, so feel free to move your basket or hanging planter in doors into
a conservatory or other sunny sheltered area before the first frost.

two are also names of E. glomeratus cultivars), Brazilian Dwarf
Family name: Convolvulaceae
Plant type: An evergreen herbaceous perennial, native to Brazil and
Light: Bright light or full sun; Can tolerate partial shade to shade but

Moisture: Performs well with regular watering and do allow soil to dry
out between waterings. Over watering can kill it. It can tolerate arid
and dry conditions, once established.
Soil: Well-drained poor sandy or loamy soil.
Propagation: Easily propagated from softwood stem cuttings. Just cut a
sprig and stick it into moist soil. Or, if grown on the ground, its
stems tend to take root where they touch the ground, so separate the
rooted stems from the parent plant with the pointed tip of a spade and
plant as desired. Another easy way is by dividing its root and stem
mass. Evolvulus can also be propagated from seeds.
