Overwintering fuschia plants to carry them to next year

Overwintering fuschia plants means keeping tender fuchsias alive through the cold so you can grow them again the next year. Most trailing and basket fuchsias are tender and will not survive a hard freeze, so in a cold-winter garden you cut the plant back, bring it indoors, and rest it in a cool, frost-free, fairly dark place until spring. Through winter the plant sits dormant with few or no leaves, then you start it back into growth as the days lengthen. Done well, this saves you buying new plants each year and lets you keep favorite varieties going.

I started overwintering fuchsias after spending a small fortune replacing hanging baskets every spring. The first year I tried it, I nearly gave up when the cut-back plants sat as bare stems in my garage for months looking utterly dead. They were not dead, just resting. By late winter they pushed new green shoots, and by summer they were back in full flower in their baskets. After several winters of this, my cool basement and garage hold a row of resting fuchsias each year, and I rarely buy a new one.

Here are the steps I follow each autumn.

The steps cover the whole process, but the details of cutting back, keeping the plant cool and barely moist, and timing the spring wake-up make the difference between plants that come through plump and those that rot or shrivel. The rest of this guide walks through them.

The fuchsia at a glance

Fuchsia (Fuchsia species and hybrids) is a genus of about 100 species in the evening primrose family (Onagraceae), mostly native to Central and South America, with a few in New Zealand. The showy hybrid fuchsias grown in hanging baskets are mostly complex hybrids of Fuchsia magellanica, F. coccinea, F. fulgens, and others, descended from crosses made in 19th-century England. Mature basket types trail 1 to 3 feet (30 to 90 cm), while upright landscape types can reach 4 to 8 feet (1.2 to 2.4 meters) in mild climates.

The plant flowers on new growth, so the dormant period is not just a survival tactic but a natural part of its cycle. In its native range, fuchsias rest through a cooler, drier season and push fresh growth when conditions improve. Mimicking that cycle indoors is what overwintering is about, and getting the cold-but-not-frozen, barely-moist storage right is what keeps the plant alive to flower again.

Hardy versus tender fuchsias

First, know which kind of fuchsia you have, because it changes the approach. Hardy fuchsias can survive winter outdoors in milder cold climates if you mulch their roots well, and they often die back to the ground and resprout in spring. Tender fuchsias, which include most of the showy trailing and basket types, will not survive a hard freeze and must come indoors.

If you are not sure, treat the plant as tender and bring it in. The cost of being wrong is low, and a tender fuchsia left out to freeze is simply lost. For hardy types you want to keep in the ground, a thick mulch over the roots after the first frosts gives the best protection.

The rest of this guide focuses on overwintering tender fuchsias indoors, which is the situation most basket-fuchsia growers face.

Cutting back before frost

Act before the first hard frost. Frost can damage or kill a tender fuchsia, so watch the forecast and bring the plant in while nights are still safe.

Cut the plant back by about half to two thirds. This reduces the amount of growth the plant has to support through the dark, low-light months, which is exactly what helps it rest and survive. Remove remaining flowers, buds, and most leaves at the same time. The plant looks stark afterward, but a cut-back fuchsia rests far better than a large, leafy one struggling indoors.

If the plant is in a large basket or pot, you can reduce the root ball and pot it into a smaller container to save space and limit how much soil stays wet around the roots. Knock off some soil, trim long roots, and repot into a snugger pot.

Checking for pests

Fuchsias often carry pests indoors, and a warm house lets them multiply. Whitefly in particular loves fuchsias, and aphids and spider mites can ride in too. An unchecked infestation weakens a resting plant over winter.

Before the plant comes inside, inspect it closely, especially the leaf undersides, and treat any pests with insecticidal soap. Check again a week later, and keep an eye on the plant through winter so a small outbreak does not build up while the plant is dormant and vulnerable.

Resting through winter

Move the cut-back, pest-free plant to a cool, frost-free, fairly dark place. An unheated garage, shed, or cool basement usually works. Aim for somewhere around 40 to 50 degrees Fahrenheit (4 to 10 degrees C). Cool temperatures keep the plant resting rather than trying to grow in poor light, and a fairly dark spot reinforces the dormancy.

Through winter, the plant needs very little. Keep the soil barely moist, never wet and never bone dry. A dormant fuchsia with few leaves uses almost no water, so check the pots every few weeks and add only a little when the soil has nearly dried out. Do not feed during dormancy, since there is no active growth to support.

The plant will sit as bare or nearly bare stems for months. This is normal. To check it is alive, scratch a stem lightly and look for green underneath.

Starting back into growth

In late winter or early spring, as the days lengthen, it is time to wake the plant. Move it into light and a slightly warmer spot, and gradually increase watering. Watch for new shoots pushing from the cut stems, which signals the plant is coming back into growth.

Once it is growing well, you can repot it into fresh mix, begin light feeding to fuel the new growth, and take cuttings from the new shoots if you want more plants. Fuchsias root very easily from soft cuttings, so this is a good chance to multiply a favorite variety.

Pinch back the new shoots as they grow to encourage a bushy, well-branched plant, which gives more flowers later. Each pinch makes the plant branch lower down.

Taking cuttings as insurance

Overwintering a whole plant is not the only way to carry a fuchsia through winter, and the two methods work well together. Fuchsias root very easily from soft cuttings, so taking a few in late summer gives you young plants as backup in case the parent does not survive its rest. If you have ever lost an overwintering plant to rot or pests, cuttings are cheap insurance.

Take cuttings from healthy, non-flowering shoots, a few inches long, strip the lower leaves, and push them into moist potting mix or root them in water. They usually root within a couple of weeks. Grown on a bright windowsill, the small plants take little space and handle weak winter light better than a large parent, much like overwintering tomatoes from cuttings.

Many growers keep both a cut-back parent plant resting cool and a few cuttings growing on a windowsill, hedging their bets. If the parent comes through, you have extra plants to use or share. If it does not, the cuttings carry the variety forward. For a treasured fuchsia you would hate to lose, taking cuttings alongside overwintering the plant is worth the small effort.

Fuchsia types and their overwintering needs

Different fuchsia types need slightly different overwintering approaches, mostly based on how cold-hardy they are. The table below sorts the common types by their winter strategy.

For cold-climate gardeners, the choice is between treating all fuchsias as tender (bringing them all in) or growing only the hardy types that survive outdoors with mulch. The showy trailing basket types are almost always tender.

Back outside in spring

Once all danger of frost has passed and nights are reliably warm, harden the plant off and move it back outside. Set it out for a little longer each day over a week or so, starting in a sheltered, shaded spot, so its leaves adjust to wind and brighter light after months in low light.

Then hang the baskets or plant the fuchsias out as before. With a winter’s rest behind them and a head start of early growth, the overwintered plants come into flower and fill out faster than newly bought ones.

Overwintering fuschia plants takes a little cutting back in autumn and a few checks over winter, and it returns the same plants year after year, saving the cost of replacing baskets each spring. For tender fuchsias in a cold climate, it is a quiet autumn routine that pays off in summer.
