About Potomac Early snapdragon

Antirrhinum majus 'Potomac Early' · also called Potomac Early snapdragon, snapdragon · flowering

Potomac Early is a tall, heat-tolerant cut-flower snapdragon bred for early bloom and long stems. Direct-sow or transplant into full sun after last frost. Deadhead spent spikes to prolong flowering. Excellent for cottage gardens and borders; thrives in cool-to-mild weather and fades in midsummer heat.

Plant type: flowering

Watch for — Botrytis grey mould: Grey, fuzzy mould on flowers and stems appears in cool, damp conditions. Remove affected tissue, space plants adequately, and water at the base rather than overhead.

The reasons potomac early snapdragon isn't blooming

Almost every non-blooming potomac early snapdragon traces back to one of these, roughly in order of how common they are:

Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.
Too much nitrogen feed, driving lush foliage at the expense of flowers (very common with general or lawn feeds).
The plant has not been deadheaded, so it stops flowering once it sets seed.
Irregular watering — drought or waterlogging at the budding stage makes buds abort.
It is still too young or was checked by a transplant and is rebuilding before flowering.

Feeding potomac early snapdragon a high-nitrogen general feed and growing it in too little sun — you get a big leafy plant and almost no flowers.

The fix — how to get potomac early snapdragon to flower

Maximise sun. Give potomac early snapdragon the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers.
Switch the feed. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
Deadhead regularly. Remove spent flowers often to keep it producing more rather than stopping to set seed.
Water consistently. Keep moisture even through budding and flowering — drought-then-flood swings make buds drop.

Light and feeding do most of the heavy lifting here. Dial in the spot with the light guide for potomac early snapdragon and get the feeding right with the potomac early snapdragon fertilising schedule — the wrong feed (too much nitrogen) is one of the most common silent reasons a healthy plant makes leaves instead of flowers.

Bloom season and what to expect

Potomac Early snapdragon flowers across its growing season (mostly summer) and, kept fed and deadheaded, can bloom for many weeks or right up to frost.

Post-bloom care so it flowers again

Deadhead, keep feeding lightly, and many will rebloom; collect seed from the best plants at the end of the season if you want to grow them again.
