How to grow a sage plant from cuttings?
Grow from leaf cuttings 1 Take a single leaf, and pot it with the base down in a potting mix. 2 Cover the seed pot with clear plastic and secure it with a rubber band to keep up the humidity. If you can change the water weekly, you can also put the leaves in a glass of water. 3 Either you cut the leaf segments horizontally or length-wise across the leaf, both parts can be used as cutting to grow from it. These plant’s leaves contain a high concentration of cytokinin, which is a type of rooting hormone due to which it does not need artificial rooting hormone.

In autumn and winter put your plants on a south-facing windowsill for maximum light, but move them out of the way of any overnight draughts. Stop feeding them and only water when the compost is dry, as plants may rot if the compost is too wet. Expect some leaves to die back and remove them by nipping them out at the base. Cut out stems when they have finished to encourage the plants to produce more.

Watering From spring to autumn, water when the top couple of centimetres of compost becomes dry, but don’t allow the pot to sit in water and allow any excess to drain away. In winter, water only when the compost is dry and allow any excess to drain away – the roots can rot in if the compost is too wet.
How to propagate streptocarpus
Streptocarpus are easy to propagate from leaf cuttings. Summer is the best time to do it, as plant cells divide quickly, promoting growth.
Growing streptocarpus: problem solving
Wilting can be caused by over- or underwatering. If the soil feels soggy, you have overwatered. Allow the soil to dry out before watering again. If the plant doesn’t recover, it may have root rot, caused by cold, wet compost – this can be fatal to the plant. If the soil is dry, you have underwatered.

It’s very easy to create dozens of baby plants, increasing your collection and creating new plants for gifts. Cut off a large, healthy leaf with a clean razor blade and slice out the central vein, leaving two leaf halves. Plant the halves in rich potting soil by standing them up with the cut side down.
How to kill a streptocarpus plant?

Can African violets grow in pots?
Image by MargarytaVakhterova. If you love the look of African violets but find them a bit too difficult to grow, try a pot or two of their hardier cousins, the Streptocarpus or cape primrose.

How hot can a strep grow?
Temperature requirements are varied, but generally growing Streps from 60˙F to the high 70's is hot enough. They will not tolerate high temperatures. This is one of the greatest challenges in their culture. The summer heat, in many areas of the country, distresses the plants and can sometimes cause their collapse. Any type of heat wave, even those that we get in Connecticut, can wreak havoc with Cape Primrose plants. When temperatures rise into the 90's, the plants will go into a wilt and the leaves get damaged or the plants collapse, as the transpiration of the leaves is far greater than what the root system can uptake.
How to fertilize a strep?
When you feed your plant, we recommend intermittent feeding with any liquid, balanced, houseplant fertilizer (where the three numbers are close together or the same). It's best to reduce the recommended fertilizer dosage by half (so if it calls for one teaspoon per quart of water, add only half a teaspoon per quart). Periodically, you should leach, or let water run out of the bottom of the pot, so you don't get an accumulation or build up of salt levels from the fertilizer. One of the symptoms of excess fertilization is a browning or burning of the leaf edge as the young leaves emerge and start to grow. As this damaged leaf matures, there will be a burned edge and a constricted area in the leaf. Remember that high temperatures along with greater leaf transpiration can aggravate this problem.
What happens to Cape Primrose plants in the 90s?
When temperatures rise into the 90's, the plants will go into a wilt and the leaves get damaged or the plants collapse, as the transpiration of the leaves is far greater than what the root system can uptake.
Where do streps come from?
Streps are known for their ability to bloom in low light. They actually thrive under those conditions. Originally from South Africa, they are found in their native habitat growing on the forest floor; that's why they have a tolerance to lower light and periods of dryness.
Do streps like wet soil?
Streps tolerate drier soil conditions and as a rule it's best to bring the potting mix to slight dryness and then thoroughly saturate the soil. A slight wilt does the plant no harm. Also, remember to water directly into the soil and do not get the leaves wet, especially with cold water.
How to propagate Streptocarpus?
To propagate Streptocarpus seeds, spread the small seeds on top of a sterile seed-starting mixture and place in a well-lit and warm area. The seeds need light to germinate. The plants are more commonly propagated by leaf cuttings, much in the same way African violets are propagated. Take a single leaf with its leaf stalk and bury it in a seed starting mix, then place the pot in a warm, humid area until new growth emerges. Finally, older, more mature plants can be divided during repotting.
Where are Streptocarpus native to?
Streptocarpus species are native originally to Africa and Madagascar (and possibly a few species in Asia).
What color are Streptocarpus flowers?
Streptocarpus flowers can be found in red (a relatively recent addition), blue, purple, yellow, white and orange. They are typically borne on upright stems, hovering over the plant's flat, textured leaves, and can be either a single flower per stalk or multiple flowers per stalk.
Do streptocarpus like direct sunlight?
They also dislike strong, direct sunlight, which will burn their leaves. Some species have the unusual habit of annual leaf die-back, with the leaves turning brown from the leaf-tip halfway down the leaf. This is normal. Finally, the healthiest and most heavily flowered Streptocarpus are those that are fed regularly.
Can you repot a streptocarpus plant?
When repotting a mature plant, be careful not to destroy too many of the fine roots near the soil surface. During repotting, make sure to use a very fast-draining soil—Streptocarpus thrives in fast-draining conditions and does not benefit from a peat-heavy soil that retains water.
