Help! How to Overwinter these Non- Hardy Plants, Tubers, Bulbs?

arbo_retum(z5 ,WinchstrMA)November 16, 2012

After a few years of container growing non hardy plants, I have finally organized my huge question of how to winter store the plants I cannot leave outside in my z.5 garden. PLEASE let me know anything

you can! and thx so much



1)-- Leave in situ planted in Glazed Pots, on Risers or pedestals (covered w/ plastic shrub covers)

2)--Open Screen Porch

3)- Bury Plastic Pots in Ground Trench

4)--Shed w/ small skylight, under Mature Hemlock

5)- Tiny Cellar 60 degrees , no windows

6)- Steps under Hurricane Door leading to Cellar Door

7)- South Facing House Plant Room w/wall of windows, skylights; open to living room, 65-70 degrees;

Filled w/ pots of Amaryllis, Xmas Cactus, Queen's Tears, Ferns , so window space is precious



(And Do They Need Water; how often?):

Pilea- Aluminum plant

Breynia- Snowbush

Pennesetum Villosum

Oxalis Cabernet

Dahlia ( can I leave planted in glazed pots and store in cellar?)

Taro ( can I leave planted in glazed pots? cellar or plant room? )

Colacasia ( """""" )

Alocasia ( """" )


Clematis w/ tulips, allium, in glazed pots

the tubers and bulbs you can bury in ground and a thick layer of mulch on top, or stored in cellar in pots of soil.

other plants can be stored in your plant room or anywhere in the house; you can easily set up some artificial lighting.

I wouldnt leave any of those bulbs/tuber in ground in zone 5 dig them all and store them in paper bags in a dark place. that cellar sounds good for them. even in a bucket covered with a paper bag will be fine. give them a slight mist in maybe feb to keep them moist and replant

I store tender bulbs in bags of peat and keep them cool, not cold. Tropical and sub tropical plants are stored in a heated greenhouse or grow room with HID and T5 lights. Even though my GH and indoor plants are warm and well lit I significantly reduce the amount they are watered. Dormant plants like brugs, plumerias and adeniums get a small amount of water every 6 weeks or so, if at all.
