I'm a very novice gardener (that may even be stretching my qualifications). I planted a bunch of Shasta Daisies, the Becky variety. I would like the flowers to spread and really overtake the garden they are in. I've been reading about deadheading the flowers, but everything I've found has been pointed towards flowers that have more than one flower per stem. The Becky variety only had one. I'm wondering how far back I should cut the flowers. To the ground? Near the head? Somewhere in the middle? Thanks for any help you can give!
You will want to cut the flower closer to where the leaves begin. This will help them to bloom again before bloom season is over. This article will give you more information: https://www.gardeningknowhow.com/ornamental/flowers/shasta-daisy/deadheading-shasta-daisies.htm
Plants will be in full sun.
This is a difficult time to transplant. High temps and hot sun strip moisture faster than recently disturbed roots can re-supply leaves. To have a chance for success, plant when the weather is cloudy, preferably for several days. Put 2-4 inches of mulch around the plant but not up against plant stems. Rig up some shade so the plant doesn't get direct sunlight. I've used open cardboard boxes placed over the plant and leaf bags over a shovel that is placed where it blocks sunlight. I've seen pictures of umbrellas used to cast shade on new plants. Keep the plant shaded for up to 5 days. After 3 days, try removing the shade apparatus for part of the day and observe for wilting. Put it back up if the plant is struggling. Keep the soil moist, not soggy. If the plant is tall, cut it back 1/3 to 1/2. You will lose some flowers but fewer leaves helps the plant survive. If you purchased the daisy at a summer sale, it may be rootbound.

I dead headed my neighbor's Shasta Daisy. Can these spent blooms be used to harvest seeds?
It may be too early to collect seeds. Were the flower heads dry and brown? If there are seeds, are they golden brown? If not, wait till the end of summer and deadhead again when the flowers have lost all their petals and the seed head is forming.
ld be wrong? We kept it in our patio, but have had mostly cloudy days for the last 2 days. We had some heavy rain yesterday so I have not really watered the plant. Weather wise we are in 50s... any tips on what needs to be done will be helpful.
They appear to be very rootbound. Once purchased, these should be planted as soon as possible, as they will be pretty crowded.
I would recommend planting, or even dividing the plant once the blooms fade.

Hello. I have been trying to grow shasta daisies for a number of years. I have had them in full sun and partial afternoon sun. However, they eventually tend to either shrivel and get yellow (like they havent had water, even though watered), or the lower part of the stems turns black and rots. I have tried fungal treatments, fertilized, but to no avail. The ones I planted for my mother though, in full sun but terrible clay soil, are doing great. Can you please advise? Thank you.
Pruning and deadheading should help. Also make sure there is proper drainage.

I have large drifts of Shasta daisies that average 3 feet tall in front of my house. We had a torrential downpour that overwhelmed our gutters and forced waterfalls of rain to overflow and beat down my daisies who now are bent and lying on the ground. Should I cut them all back to the ground and hope for regrowth?
Wait first to see if they pop back up. That is usually the case unless they are too tall. Also, bent stems can be taped where they are bent. Here is more in the articles below. If they don't revive in a week, go ahead and prune them by about half.

I am having a hard time to figure out what is wrong with my Shasta Daisy. Is it fungus, slugs or snails, spiders. I am lost. I live in North Texas so this 3 year old plant gets lots of sun. It bloomed super this spring but now the leaves are all brown and have a kinda gray/ white circular spots.
This is, definitely, a fungal infection. This is likely Downy Mildew.
