- Native Region: Southern Africa
- Growing Zones: USDA zones 3 to 9
The Right Growing Conditions
Sunlight Requirements
Ursinia do best in full sunlight. They generally need at least six hours of direct sun daily. This is a big deal for their growth and abundant flowering. If you plant it in a shaded area Ursinia can grow leggy and give you fewer flowers.
- Sunlight Intensity: In regions with very intense sun think about some light afternoon shade to protect the plants from getting burnt.
- Seasonal Sunlight: Track the sun’s path through the seasons. In the early spring some areas might get less direct sun which may mean you have to start the seeds indoors so they get the light they need from the start.
Soil Preferences
Ursinia prefers well drained, sandy soil. It can tolerate poor soil but will not do well in heavy, clay like or waterlogged conditions.
- Improving Soil Drainage: If you have heavy soil mix it with sand, gravel or organic matter to improve the drainage. Raised beds can also be a good solution.
- pH Levels: Keep the soil pH between 5.5 and 6.5. Use pH testing kits so you can monitor and change the soil pH. If necessary you can add sulfur to lower the pH while lime can be used to raise it.
Watering
While Ursinia is drought tolerant once it’s established you must water it regularly during the growing season. Water it deeply but let the soil dry out between waterings so it doesn’t get overwatered, which will cause problems.
Fertilization
Ursinia does not need heavy fertilization. A slow release fertilizer used in the early spring will be good enough. Avoid over fertilizing though as it can make the foliage to grow too much and flower growth to slow down.
Planting Ursinia
From Seeds
Starting Ursinia from seeds is really straightforward:
- Seed Starting Indoors: Begin seeds indoors 6 to 8 weeks before the last frost. Disease can be a worry at this point so use seed starting trays and a seed starting mix that is sterile.
- Transplanting:
When the seedlings reach around 4 to 6 inches tall and have two sets of leaves then harden them off. Once you’ve done this transport them outdoors. Then slowly into rice them outdoor conditions over roughly a week so they don’t get shocked from the transplant and new environment.
Direct Sowing
Seeds can also be sown directly in the garden after the last frost.
- Correct Spacing: Space the seeds so they’re about 8 to 10 inches apart. This will let the air flow between each plant and reduce the chances of fungus.
- Mulching: Once you’ve sown them add a small layer of mulch as it will keep away weeds and hold on to moisture. An organic mulch, something like leaf mold or straw, is a great choice.
Transplanting
If you have started the seeds indoors then transplant the seedlings outdoors when they get to about 4 to 6 inches tall and after the last frost. Give them enough space so they get enough air circulating between them.
Caring for Ursinia
Watering Routine
- Water regularly during dry spells.
- Let the soil dry out between watering to stop root rot.
Mulching
Put a layer of much around the plants to help stop weeds growing and keep moisture in the soil. Straw or compost works best.
Pruning and Deadheading
Deadheading often will support the continual flowering and keeps them looking tidy.
- Pruning Techniques: You will get a bushier growth if you pinch back the going plants. Pinch or use clean scissors to remove any spent flowers.
- Seasonal Pruning: Cut back your plant at the end of the growing season as it will stop diseases and mean pests don’t overwinter in any dead foliage.
Pest and Disease Management
Keep a close eye out for the likes of aphids and spider mites. Ursinia is generally good at resisting pests but it’s still a good idea to look in once in a while just in case. If you find any then use a natural remedy or insecticidal soap.
- Common Pests: Spider mites and aphids are the ones to look out for. Ladybugs will naturally predate aphids so can be used to control any you find. If you get a bad infestation use insecticidal soap.
- Disease: Fungal diseases can be kept at bay by making sure there is good air flow around them. Don’t water from overhead though as when the leaves get wet it can result in fungus growth.
Fertilization
Ursinia likes a light feeding. But over fertilizing can result in lots of foliage growth but far less flowers.
- Balanced Fertilizers: A slow releasing, balanced fertilizer is best. Use it the spring and says follow the instructions on the packaging for the right rate of application.
- Organic Options: Organic fertilizers can make the structure of the soil better and release the right nutrients slowly. So if you can go for compost or well rotted manure.
Winter Protection
If you’re in a cold region then you could grow Ursinia as an annual. Alternatively give it some protection as it grows with cloches or row covers. Get it right and it will extended how long your Ursinia flowers for.
If you’re in a milder area then Ursinia can overwinter without lot of protection. Use a thick layer of mulch around the base of your plant and it will cover the roots.
Extra Tips
Companion Planting
Ursinia goes well with quite a few other plants, drought tolerant ones especially.
- Plants That Work: Plant Ursinia alongside Nasturtium and Sedum as they bring in lots of insects that help. Plus their colors all look great together.
- Edging and Groundcover: Ursinia works well as an edging plant along the borders or paths of gardens. The bright flowers make a real impact on anyone walking through.
Seasonal Care
Winter Protection:
- Ursinia can overwinter without needing a lot of protection if you’re in a milder area. Add some mulch around the base of the plant to protect the roots.
