The plant needs at least 4-5 hours of direct sunlight for best results.

Soil needs for mother of thousands plant
Like all succulents, a well draining soil mix is needed for kalanchoe houghtonii since the plant is prone to root rot. You can choose a specially formulated soil for succulents, or add perlite and coarse sand to ordinary potting soil.
Avoid excess organic matter in the soil of kalanchoe houghtonii.
Kalanchoe houghtonii likes a neutral to slightly acidic soil with a pH about 7 – 7.5.
How to fertilize
It is not necessary to fertilize, but doing so will encourage growth and promote flowering.
Feed twice a week during the growing season with a fertilizer for succulents. Either a liquid fertilizer or slow release granules works.
Do not fertilize when the plant is dormant, during the winter months.
Avoid fertilizers that are peat-based. Since succulents need to completely dry between each watering, it is difficult to quickly soak the roots of a succulent grown in peat.
Kalanchoe houghtonii flowers and foliage
Kalanchoe houghtonii has an upright growing habit with boat shaped leaves with serrated margins. The leaves usually have purple splotches on the under side.
These leaves bear tiny plantlets along their edges.
The plant can is prolific and can be very invasive. If grown in a garden bed, it can choke out nearby plants. For this reason, kalanchoe houghtonii is best grown in a pot.
The mother of thousands flowers are pendulous, and come in shades from pinkish yellow to dark red. The flower stalk is tall and can contain up to 100 long-lasting flowers.
This succulent flowers in late winter to early spring from the second year of growth going forward. Like the Christmas cactus, kalanchoe houghtonii produces flowers during shorter days with cool temperatures.
Kalanchoe houghtonii will grow to over a foot in height quite quickly.
In the right conditions, the stem of a mature plant can reach up to three feet high and the leaves can be 6-8 inches long and 1 1/2-2 inches wide.
Large plants can get very top heavy, since the leaves and plantlets are so heavy. This can cause the stem to bend down and send out lateral roots.
This happened to my plant last summer. Fortunately, stem cuttings root easily, so I was able to start my plant in a smaller size when I brought it in for the winter.
Diseases and insects
Like most succulents, fungal diseases caused from over-watering are something to be on the look out for. This could show itself with limp leaves that easily fall off.
Kalanchoe houghtonii is not usually affected by pests.
The most frequent diseases are those caused by fungi, which cause root rot and the appearance of white spots on the leaves, or the blackening of the tips. Taking care when watering and allowing the plant to dry between waterings will avoid this.
