Planting Begonias

We recommend starting begonia tubers indoors in the late winter, around February or March. If starting indoors, place planted begonias in a warm location with indirect sunlight, preferably an eastern, western, or south facing window. If you don't have an indoor window space, you will need a heat lamp to allow some light for growth. However, tubers can be planted from February to June depending on your region. In areas with hot summer temperatures, it's best to have begonias established earlier in the season. In colder zones, tuberous begonias are tender and cannot be placed outdoors during frost. Come spring, once the ground warms and the chance of frost is over, bring your begonias outdoors and either keep them in containers or transplant into the garden.

Planting Steps

  1. Prepare your garden bed or container. If planting in a garden, dig a hole a few inches deep to cover the tuber. If planting in a pot, find a pot that is twice the size of the bulb. Fill the pot 3/4 full with potting soil. Choose soil mixes with peat moss, because they retain moisture and create slightly acidic soil.
  2. One side of the tuber has a hollow dip and the other is round. Place the tuber round side down. The hollow dip is the top, sometimes it will already be sprouting buds. If the buds are coming up, gently place the tubers in the pot. The new growth is fragile, so try not to bump or break it.
  3. Cover tuber with soil, and water around the bulb. Keep pot or garden moist, but not to wet. Too much water will rot your begonias. Expect growth in 3-4 weeks after planting. If growing conditions aren't ideal, begonias can take longer to grow.
  4. After begonias have sprouted and are a couple of inches tall, you can transplant if desired. If you live in colder climates and it's free of frost, you can place outside.

Watering and Fertilizing

After planting tubers water slightly every few days or when the soil dries out. Begonias will rot if over watered, it's best to keep their soil just barely moist. Always water around the tuber, not directly on it. Fertilize every other week with a 20-20-20 organic fertilizer.

Aftercare and Storing Bulbs

In the fall after the leaves turn yellow, and or temperatures reach below 40 degrees at night, bring your begonias inside and use as a house plant or save for next spring. Begonias will naturally begin to slip into dormancy by themselves. In colder zones dig up tubers once the foliage has passed and store in a cool, dry, non-freezing place until spring. Allow tubers to dry out for 5-7 days before storing to reduce mold and rot. It is best to place tubers in a cardboard box or paper bag full of peat moss. Make sure to label the tuberous begonias for the following season.

      Comments about American Meadows Scarlet Tuberous Begonia:

      I have been growing tuberous begonias for years, though this was the first time I ordered from American Meadows, as my usual supplier was out of the colors I wanted. I start them ahead of time in the house. When some failed to sprout I requested a replacement of those varieties. Among those, also some of them did not sprout. I believe these may have been treated with a chemical to reduce sprouting in storage, otherwise I don't know why a firm tuber would not do so. Those that did sprout produced few or no blooms, and some stems broke off at the base. Out of at least 12 planted, I got perhaps 4 flowers. A great waste of effort. Last year's tubers from another company grew and bloomed well as usual, so it was not a weather or cultural issue.

        I love this begonia and used in hanging and patio pots. Stems can beak easily, so keep out of traffic lane.

          Comments about American Meadows Scarlet Tuberous Begonia:

          I planted these in an area that gets partial sun... they were yellow-green in leaf color and did not produce any blooms. Only the tuber that was placed in full shade had green leaves and red blooms. If you are in a milder zone like me (zone 7), be sure to watch the sun exposure!

            I use them in hanging baskets with annuals. These like heavy feeding and have bloomed well after mid July.

            USDA Hardiness Planting Zones

            To determine if a plant is sufficiently cold hardy, the USDA created numbered zones indicating winter low temperatures; the lower the zone number the colder the winter.

            • If the coldest winter temperature expected in your area is -15°F (zone 5) then any plants rated zones 3-5 will survive the winter temperatures in your area.
            • If you live in very warm winter areas (zones 9-11) plants with zones 3-4 ratings are not recommended. The lack of freezing winter temperatures do not provide a time for winter dormancy (rest).
