Pinch off blossoms in spring and early summer so that the plant will not bloom until fall.
I know that the fungicide Thiram can cause buds to drop if used too close to budding and blooming.
Trim off the dead parts of the plant. Fertilize lightly and pinch blossoms that are too early.
Too much salt can kill plants including chrysanthemums.
Chrysanthemums are day length sensitive, meaning the amount of light they receive determines when they will bloom. Normally they do not start blooming until September. Depending upon the variety you have, it could be as late as the end of October.
The chrysanthemums that florists use are annuals. However there are perennial chrysanthemums and as long as they are not planted too late in the year to develop a good root structure, they will survive the winter and bloom again.
Chrysanthemums need water so they have to be watered in droughts. If it is too wet, they can get fungal diseases. They can get aphids, spider mites and leaf miners. New cuttings can get bacterial infections. And chrysanthemums are toxic to children and pets.
To properly prune clematis vines for optimal growth and blooming, prune in late winter or early spring before new growth begins. Remove dead or weak stems, and cut back healthy stems to a pair of strong buds. Avoid cutting back too much, as this can reduce blooming.
Mission was accomplished: Iraq was removed.
If the weather has been too cold or hot, the flowers may not have been pollinated by insects sufficiently. At certain temperatures, the plant may only produce male flowers.
Rhododendrons prefer partial shade for optimal growth and blooming, as full sun can be too intense for them.
To effectively prune hydrangeas for healthy growth and abundant blooming, prune them in late winter or early spring before new growth begins. Remove dead or weak branches, as well as any old or faded flowers. Cut back about one-third of the oldest stems to encourage new growth. Avoid cutting back too much, as this can reduce blooming.
To properly prune mophead hydrangeas for optimal growth and blooming, prune them in late winter or early spring before new growth begins. Remove any dead or weak branches, as well as any old flowers. Cut back about one-third of the oldest stems to the base to encourage new growth. Avoid cutting back too much, as this can reduce blooming.
