Begonia Sunshine Carpet is a special economy mixture ideal for mass bedding plants. This variety produces a lovely mixture of flower colours and foliage in both deep green and bronze and grows to an approximate height of 30cm. It is a fibrous rooted type which produces thin, thread like roots that branch out in all directions.Wonderful for bedding, containers and borders.
WHEN TO SOW
January to March
WHERE TO SOW
sow seed on teh surface of lightly firmed, moist seed compost. Do not cover the seed. Place inside a propagator or cover a tray with polythene or glass and place in a warm place. Keep at a temperature of 24-27°C (75-80°F). After sowing, do not exclude light as this helps germination. Keep the surface of the compost moist but not waterlogged; germination will usually take 15-60 days.
WHAT TO DO NEXT
As soon as a few seedlings emerge remove the cover but spray regularly to keep moist. When seedlings are large enough to handle prick off into trays 5cm (2″) apart. Gradually harden off in late April/early May to plant outside 20cm (8″) apart once all risk of frost has passed.
As the seed of Begonia is very, very fine, mix a little dry sand in the sachet and sow thinly.
FLOWER SEED SOWING TECHNIQUE
HALF HARDY PERENNIAL, BUT TREAT AS HALF HARDY ANNUAL
Use seed trays or plastic modules and a good seedling compost, preferably using a peat substitute. For small sowings standard pots can be used.
Firm the compost lightly and moisten before sowing. Very fine seeds, like Begonia (where there are more than 60,000 seeds to a gram) should be mixed with dry horticultural sand to avoid one big clump of seed, and to help see where the seed has been sown.
As a general rule, the depth of sowing depends on the size of the seed. Aim to cover the seed with compost or vermiculite to the same depth as the size of the seed. Very fine seed need not be covered at all.
Sow thinly and cover the tray with a sheet of glass with paper on top. Wipe the glass every day and inspect the tray for signs of germination. Sowings in pots can be enclosed in a polythene bag for the same effect.
As soon as seedlings break the surface, remove the glass and paper or polythene bag. If left under glass they will become leggy and weak. Keep moist with a fine spray.
When the first set of true leaves (not the seedling leaves) have formed they should be pricked off into trays, setting the seedlings about 4-5cm (1 1/2-2″) apart. Always handle by the leaves and not the stem and use a fork or knife blade to ease them out of the compost. Keep in the shade for a couple of days after pricking off.
Gradually harden the plants by increasing ventilation and moving the trays into a cold frame and finally outside for 7 days before transplanting into the flowering site.
