Q. Shasta Daisy

I bought a Shasta daisy about one year ago. It made it through the winter months and reappeared this spring, but with ugly black spots on the leaves. It is the only plant in my garden that has these black spots. What is causing this, and what can I do about it? I am worried about my other perennials.

It sounds like a fungus, likely black spot fungus. Treat the plant with neem oil. Here is more information on it:

Q. Protecting Shasta Daisies From Garden Pests

How can I protect my shasta daisies from garden pests, such as rabbits? I live in Cheyenne, Wyoming, and we are abundant in antelope and rabbits. I planted two beautiful shasta daisies a few weeks ago, and they have flourished, nearly doubled in size and have multiple buds/blooms! The problem is this: something comes along in the night and eats ONLY the petals off the blooms, leaving an unsightly stalk with yellow center. What is doing this, and how can I prevent it? Any suggestions are welcome.

It is either rabbits or something deer like. This can help with rabbits:

I am not familiar with antelope, but if they are like deer, predator urea may work as will fishing line set up around the plant. You don't need much, just enough so they run into it with their nose. Because they can't see it, it makes them nervous and they leave the plant alone.

Yes, shasta daisies often rebloom several times throughout the growing season with regular deadheading.

Q. root bound shasta daisies

I already planted some root bound shasta daisies in my front yard. Will they die if I don’t dig them up and cut the root bound areas? Or can I sink a butcher knife into the ground and cut them that way?

They won't die if you leave them. In rare cases, rootbound plants put into the ground will continue to grow in a circular pattern that then strangles the root ball, but this does not usually happen. In most cases, even if the plant is rootbound when planted and the roots are not loosened, the root ball will in most cases spread out and grow just fine.

If you are still worried, you can just use a spade and plunge it into the soil around the plant in one or two locations to help break up the root ball.

Q. end of season sale “Shasta Daisies” are rotting

I bought them in bad shape and rootbound. But once I planted them, they seemed to be doing fine. Now some of the plant’s leaves are looking black and wilted, almost like it’s rotting. HELP!

Most likely over watering - Are the daisies planted close together? Mine still do the same because they multiply like rabbits!
I've given a bunch away, and transplanted even more...each year they keep popping up!
ALWAYS remove the yellow/spotted leaves ASAP - could be mold which spreads. I cut down to about 6" in fall, then in spring when they show signs of growth start dividing! PS - mine grow in sun and shade, and can get very tall!

Hope this helps!

Q. Shasta daisy

Why are my Shasta daisy blooms’s middle turning brown, and the blooms stay small – immature?

Answered by

A.

In many areas, it has been very hot and, while shastas are normally very drought tolerant, this browning could be caused by too little water to deal with the heat.

It may also be a fungus.

I would recommend watering them some and then treating them with a fungicide to be on the safe side.

Q. Black Moths

There are black moths swarming about and landing on the leaves of my snow cap plants (not sure this is proper name for plants). They appear to be laying larvae. How do I treat this?

Treat the plants with neem oil. This will help prevent the eggs from attaching to the plant. It will also take care of any that may already be there.
