Planting Zone

What planting zone is Lenhartsville, PA? Also, can I plant cannas now and leave them out all winter?

ANSWERS

Hello and thanks for contacting us at Gardening Know How. Follow this link for some help with your zone. Looks like you are either zone 6 or 7,

http://www.gardeningknowhow.com/planting-zones/pennsylvania-planting-zones.htm

In zones 7-10 cannas can be safely left in the ground during the winter. Zone 6 is a median climate for cannas. Cannas grown in zone 6 can be left in the ground during less severe winter seasons but always have the possibility of freezing during more severe winters. Cannas grown in zones 5 and colder must be dug and stored during the winter. So looking at your zone I would say it is best not to plant them them out now and leave them all winter as you could lose them.

Canna Plants

Someone gave me canna plants that had been potted. I asked the garden club about caring for them, and they said to try to get as much soil off the roots and put them in a cool, dark place for the winter.  I want to put them in pots this spring, but I don’t know how. Do they spread? The root is the size of a cantaloupe to a watermelon. What kind of soil? How much sun?

Are Canna Seeds Easy to Grow?

I harvested the Canna seeds from my plants last fall. I would like to know the best way to raise them if you have had any luck raising them?

The fastest way is to nick the seeds and soak them in water till the radicle (first root) appears which will be in about 4 to 10 days. You can then pot them up with the radicle pointing downwards - the first leaf will appear about a week later. Spring is ideal for starting them. They grow quite fast. That being said, the hardest part is nicking the seed. Some people have success with a big nail clipper, but it doesn't work for me. I use a damp towel to hold the seed and use a sharp exacto knife. If radicles don't show in 10 days, check the seed and if you see bubbles in the skin, just peel off the first layer and soak again.

Canna Lily No Flowers Yet

I bought this plant in June with no flowers and planted in the pot to survive through the winters. Plant is growing big but I do not see any flowers yet? Am I going to get any flowers this year? Its bloom time says late summer.

ANSWERS

A lot of times, plants won't bloom the first year they're planted. It takes a lot of energy to put out a bloom and will most likely focus on reproducing themselves through the roots before they bloom. Insufficient sun and water, poor soil, and overcrowding can also prevent the Canna from blooming.

How Do I Prune Burgundy Canna Lilies?

Have five beautiful recently planted, but mature, burgundy canna lilies. Several reach over 6 feet to flower. Two have broken off because of the height and weight with the large flowers. Is it ok to cut them above a new growth notch?

ANSWERS

Yes, you can do that. They should bloom again after being trimmed down a bit.

This issue may indicate that they are not quite getting enough sunlight, so you may want to consider that when planting them next year.

Should I Deadhead Canna Blooms

Should I deadhead my canna blooms? I also wonder what is the left over part of the flower after it blooms?

ANSWERS
cannalily

I, too, am asking that question from SC. Are the "left overs" in doylejo "buds" from which new cannas may grow? I am very new at this. Russ in Columbia
