Spring blooming bulbs like tulips, daffodils, alliums, fritillarias, the Madonna lily, and most of the minor bulbs should experience some cold and dormancy, and should always be planted in the fall season.

A: It depends on the plant. Some short-lived perennials should be divided more often. Some like peonies or hostas resent division and should only be lifted and divided for more plants or if they are not thriving in their position. Check cultivation instructions for the particular plant.

But generally: when overcrowded and not blooming well; when central crown becomes woody and starts to die out or plant no longer fits well in its allotted growing space.

Primer on Perennials
Q: My flowers aren’t blooming, why not?

A: there are many reasons this might be the case, with the most common reason being not enough sunlight. Another consideration is that perennials take longer to come to blooming age than annuals, which by nature are one season plants. A perennial may take one or even two years to actually bloom for you.

Overcrowding is another reason they do not bloom well. Try dividing, or perhaps the plants need fertilizing. Be sure to use fertilizers which have the right formulation for blooming plants. Look at the N-P-K numbers, try something like 10-52-10, where the middle number is larger. For organic growers add a type of bone meal.

Shrubs

Q: When should I prune a Mugo pine?

A: The right time is when the new spring growth begins. The ends of the branches called “candles” should be cut in half.

If you cut off the ends of old growth, they will not grow back. So be sure to trim the candles every growing season to keep mugos in shape.
