Camellia reticulata · also called net-vein camellia, yunnan camellia · flowering

Camellia reticulata, the net-vein camellia from Yunnan, China, produces the largest flowers of any camellia — single to semi-double blooms up to 20 cm across in shades of deep pink to rose-red, appearing late winter to early spring. It is a more open, less tidy shrub than C. japonica, requiring milder climates or frost protection; spectacular in sheltered coastal gardens.

Plant type: flowering

Watch for — Frost damage to buds and flowers: The large flowers are among the most frost-sensitive of any camellia. Hard frosts below −3°C damage or destroy open flowers and buds. In the UK, grow in frost-free or well-sheltered conditions; fleece plants or bring container specimens under cover when frost is forecast during flowering.

The reasons net-vein camellia isn't blooming

Almost every non-blooming net-vein camellia 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 net-vein camellia 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 net-vein camellia to flower

Maximise sun. Give net-vein camellia 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 net-vein camellia and get the feeding right with the net-vein camellia 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

net-vein camellia 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.

For everything else this plant needs day to day, see the full net-vein camellia care brief and its watering schedule — a stressed, badly watered plant rarely has the energy to flower at all.

net-vein camellia blooming — frequently asked questions

Why won't my net-vein camellia flower?

net-vein camellia blooms on the season's growth given enough sun, warmth and the right feed — there is no cold or photoperiod trick, just good growing conditions and a bloom-leaning feed. The most common reason it is not happening: Too little sun — most of these need full sun (or very bright light) to flower well; shade gives leaves, not blooms.

How do I make net-vein camellia bloom?

Give net-vein camellia the sunniest spot you have — for most bedding and fruiting plants, more direct light directly means more flowers. Move off high-nitrogen feeds and use a higher-potassium "bloom" or tomato-type feed as it comes into flower.
