Growing Morning Glory in Containers

Planting Morning Glory in Pots

Question:

I've been thoroughly warned about morning glory! Can I simply plant it in a pot and avoid all the drama of it taking over my garden? Will my moonflowers do the same? All my seeds have begun to sprout... so there is a need to plant soon.

Answer:

Marisa,

Yes! Growing morning glories in containers is an easy way to avoid the potential of a hostile takeover in your garden. Moonflowers are not considered as invasive as morning glories, but they also grow well in pots. In fact, I would recommend planting some of each (4 to 5 seeds) together in the same pot. When the daytime blooms of the morning glories fade, the moonflower blooms will replace them in the evening.

There is some debate over whether or not morning glory roots grow best in shallow or deep containers. I have grown them in shallow planter boxes as well as deep containers. They have done equally well in both. The most important thing is that you give them something to climb on. It doesn't need to be a heavy-duty support, just make sure you have it in place before you sow your seeds.

Also, exercise caution when fertilizing. A little compost or a slow release organic fertilizer mixed in with a quality soil is all you need. Too much fertilizer, and you'll get lots of green and very few flowers. I don't use any on mine.

Moonflowers and morning glories are related and have similar growing requirements. Give them full sun and moist (not wet), well-drained soil. Remember that containers tend to dry out quickly, so check their moisture levels often.
