Begonias
Nothing flowers in shade like a begonia. We have said so in the catalogue for the best part of a century, and the range still proves it. Doubles: big rose-like blooms, July to the frosts. Giant Pendulars: the basket ones, colour spilling over the rim all summer. Champagne: soft apricot yellow, an old favourite. Odorata: the rare thing, a begonia with scent. Start the tubers indoors in spring, hollow side up, barely covered. Out after the last frost. Lift when the first frost blackens the leaves, and store dry.

Planting Begonias for Vibrant Long Lasting Displays
When is the best time to plant begonia tubers?
They should be planted from the end of March to the beginning of April in a place where the temperature is cool enough to allow the young sprouts to grow without risks from frost like an unheated greenhouse. If you want to place the begonia bulbs directly in the garden, wait until after mid-May, which is approximately when the last chance of frost occurs.
Why begonias tubers are perfect for shade and damp areas
The exotic begonia tubers, which begin turning in early summer to autumn, have a cascade of blooms and striking foliage and are especially good for partial shade and cooler and moist regions. Unlike traditional bedding plants, these are critical in beautifying shaded borders, hanging baskets, and containers. If you give them the right conditions to start, they will produce persistent blooms for a long time.

How to Plant Begonia Tubers for Strong healthy Growth
When starting, plant them using the hollow side facing up in damp, well drained compost, and cover them with a dusting of soil. Do not plant them too deep, because it can hinder their growth. Early in the growth season, the tubers will take time to develop a strong root system, so patience will reward you with strong .
Watering and care for healthy begonias
Do not water them too much until you can see some growth above the soil. Then, it’s important to find the balance between keeping the soil moist, not allowing it to go too dry, and not keeping it too wet, or tubers and roots will begin decaying. Don’t be too quick to move the into a larger container. They grow horizontally and will establish much better and be stronger for it, allowing them to be moved into a larger container.
