Tuberose


QUICK REFERENCE PLANTING GUIDE

1. Light/Sun Exposure - Full sun to partial shade.

2. USDA Hardiness Zones - Garden hardy in-ground zones 8 to 11.  Must be dug and stored in zones cooler than 8 (3 to 7).

3. Planting Distance - 6 to 12 inches apart in ground.  One plant per 12 inch or larger container.

4. Mature Height/Spread - 12 to 18 inches tall with a similar spread.

5. Bloom Time - Summer to fall.

6. Planting Instructions - Dig a hole twice as deep and twice as wide as each dormant bulb. When dug, the hole should be big enough to allow the dormant bulb to be covered with 1 inch of soil.  Place bulb in hole and cover with soil, firming the soil with your fingers. Water thoroughly.

GET THE MOST ENJOYMENT

There’s no better way to bring vibrant beauty to your garden and to enjoy a continuing supply of gorgeous bouquets for your home than to plant fragrant tuberoses (Polianthus) either in the garden or in containers.  Discovered in the wild in 1870, this Victorian bulb is a classic.  Native to Mexico and the tropics, tuberoses have been a traditional wedding flower in Mexico.  The fragrance of these bulbs will fill your garden and home with a perfume that is very similar to the exotic Gardenia plant.  Used as a key perfume component for centuries, the fragrance of tuberose is sweet and heavy.  It is also used in cut arrangements as it is very long lived in vases.

SOIL PREPARATION

Although these plants will perform well in average garden soils of all types, we recommend having your soil tested periodically by the local County Extension Office.  These tests can determine if the soil needs any amendments to enhance your plants' growth and performance.  See below for our recommended practice to improve your soil without any additional testing:

1.  Spade or till the soil to a depth of 12-18 inches.

2.  To provide nutrients and improve drainage, add organic matter to your soil by mixing in a 2 to 4-inch layer of dehydrated manure, garden compost, shredded leaves, and/or peat moss.

3.  After active growth begins, periodically feed with Cottage Farms' water soluble Carefree Bud-N-Flower Booster. Plants in containers need more frequent watering and feeding, especially when in active growth and bloom.

CONTINUING CARE

Water - Your plants require 1" of rainfall (or equivalent watering) each week when planted in the ground.  Do not allow plants in containers to dry out.  In a container that is exposed to full sun, water it well at least once every other day, and possibly every day, during periods of intense summer heat.  You may wish to temporarily move containerized plants to an area where they are shielded from the hot summer sun (i.e., in the shade of a tree, on a porch near an overhang).

Mulching - Apply a 2-4 inch layer of shredded bark, compost or other organic mulch around your plants to promote moisture retention, maintain even soil temperatures, and to discourage weed growth.

Weeding - Keep the area around your plants free of weeds. Weeds compete with all plants for food, water and light. Walk around the garden periodically and pull weeds, including the roots, as soon as you see them.

Grooming - Clip off dead or unsightly growth to maintain attractive form and shape.  Deadhead or remove flowers when blooms have faded, leaving as much foliage as possible.  As long as the foliage remains green it will gather sunlight and transmit energy into the root system for the following growing season.    

Feeding - Feed your plants once every 2-3 weeks during the growing season with a water-soluble fertilizer such as Cottage Farms' Carefree Bud-N-Flower Booster.  Discontinue feeding after September 1st so your plants can harden off for winter dormancy. Resume fertilizing when new growth appears in the spring.

Winterizing - In zones 8 through 11 you can leave these bulbs in the ground provided they are mulched through the winter months. Just cut the foliage back after the first killing frost and cover with a 2-4 inch layer of leaves, compost or mulch.

In zones cooler than 8 (1-7) the bulbs should be dug up or lifted before the first killing frost.  Pull the plants out of the ground leaving the foliage attached. Lay the plants in a shady area for 24-48 hours to dry. Then cut the foliage off down to the bulb and place the bulbs in dry peat moss, perlite or vermiculite in a location where the temperature stays around 45-55 degrees. Replant the Tuberose bulbs each spring after the danger of frost has passed.

Containerized plantings can be moved indoors to a cool spot (i.e., unheated garage, shed) in winter where the plants will go dormant in the container.   

If you keep the bulbs dormant in pots, simply move the pots outdoors or replant your container outdoors as soon as all danger of frost is over for your planting zone.

 

CAUTION: Not all plant material is edible. Though most plants are harmless, some contain toxic substances which can cause headaches, nausea, dizziness, or other discomforts. As a general rule, only known food products should be eaten. In case of ingestion, please contact your local poison control center at once and advise them of the plant ingested. Keep out of reach of children.
