Shastas need sun to bloom. Make sure they get at least 6 hours of sun. Add a light application of a slow release plant food to the soil in the spring and topdress with some compost.
There are some black dusty mold (powdery) on my plant wilting stem by stem :(! what do i do??
It sounds like your plants have sooty mold. This fungus develops on honeydew, a sticky, sugary substance that aphids, mealybugs, scales, or other insects secrete while sipping sap from your plants. The fungus doesn't harm the plants directly, but may inhibit growth by blocking out needed light to plant tissues. You can gently wipe the mold and honeydew off the plants with a damp cloth.
If you control the sap-sucking insects, you will prevent further mold from developing, and also prevent the plant from wilting. Check to see if there are lots of little insects attached along the stems and leaves of your plants. Mealybugs look like tiny white, segmented insects, sort of like mini-pillbugs. Aphids are tiny pear-shaped insects with antennae; the color can vary with species.
If you see aphids or mealybugs, you can wash them off with a strong spray of water; keep spraying plants every few days, and get the undersides of the leaves, too. To control heavy infestations, you can use insecticidal soap, according to manufacturer's directions. If they still don't go away, ask your local garden nursery for stronger organic options. There are also beneficial insects that attack mealybugs or aphids.
Scales, which look like bumps (various colors, depending on species) along the stems, are harder to control. There are some beneficial insects that attack scale. You can gently pick off each scale off one plant, for mild infestations, or use a soft toothbrush dipped in soapy water to gently rub them off the plant. For heavier infestations, ask your local nursery for products to control scale.
After they have seemd to 'peak out' and have turned brown will they continue to bloom if they are trimmed? It's only been about 30 days of blooming.
How much water is too much? We just planted them. We live in southern CA and they are getting daily water but are looking droopy and the flowers are already turning brown. Thanks!
Water plants during the summer if rainfall is less than 1 inch per week. You can test amount of rainfall but putting out an empty tuna can and measure the level of water inside. If you have tall varieties, they may need to be staked to stand upright. Avoid overwatering which can lead to droopy daisies and disease.
Do you have to cut off dead flowers? Mine all turned brown and they are getting a twenty minute sprinkle daily.
Thx
