Last spring

Last spring

This was going to be a post about trees, but I just got an email asking me about another topic that is equally on my mind at this time of year. In fact, both in the spring and fall, I am focused on trees and bulbs more than on traditional garden perennials. Having just completed my third bulb order, bringing the grand total up to about 600 or so, I’m all ready to address the concerns of Gayle from Maryland, who wonders about planting bulbs in pots as follows:

Do I plant the bulbs in the containers and leave them outside—or put the pots in the garage.

The bulbs should be tightly planted at the normal depth (3x their height or thereabouts) in the pots and then placed in a protected area (unheated garage or shed). They can’t be left outside as they’d likely freeze and turn to mush and the pots, if pottery, would likely break.

 If in the garage do I need to water them through the winter?

They can be watered once when planted and again, soon before moving them outside (mid-March for me, maybe earlier for zone 7, where Gayle lives.)

 Can I plant the pots now?

In 7, I would wait a couple weeks.

Do I plant them in the pot like I would in the ground —about 6 –8 inches down?

See 1.

I wanted to do a pot of paperwhites and I know most folks use them for forcing indoors—but I have always had issues with them flopping over—so I wanted to do them in a pot for outside. Can paperwhites be used for an outdoor container?

I think they are too tender for this method (in either of our zones). What I do is plant them in tall glass vases, with stones at the bottom. The tall sides support their stems and they get plenty of light. I don’t think you can grow these outside unless you’re in Texas, CA, or similar, ie, hot. I would try some of the different varieties, like Erlicheer or Grand Primo; they have nicer scents. They also benefit from a couple weeks in a dark, chilly area after planting.

 To force hyacinths is it as easy as putting them in a tray with rocks and keeping the rocks filled with water?

No. They need at least 8 weeks of cooling. You can buy them pre-chilled or do it yourself. Old House Gardens has a great method, or you can do what I do, plant them tightly near the top of pots, chill them in a cold dark attic or root cellar for about eight weeks (35–45 degrees), or when you see a couple inches of growth. I don’t like them in trays; they really flop. They need some support, so I plant them in soil. Sometimes I use glass hyacinth vases, and lean them strategically.

Thanks for your questions, Gayle, as this is one of my  obsessions. I don’t have the space to plant a lot of bulbs outside and these methods avoid some of the problems they have there. I know we don’t do “how to” on Rant that often, but when it comes to bulbs, all bets are off! Here is my Fine Gardening article on this.
