You also don’t need to worry about sudden drops in room temperature if the propagator has a thermostat. For safe storage, keep your propagator in a shed or garage rather than in a greenhouse where water is used nearly all year.
With seven individual little units, you can sow several seed varieties with no risk of contamination from disease. The vents at the top of each lid are easy to open, and as the units are so small, they are simple to wash up in a normal household sink.

If you are taking a few cuttings or sowing just a few seeds every year, then this pad might be just what you are looking for (it can be rolled up to store).
The rubber mat is splash proof, so can be wiped clean, and pots that have drained after watering can be placed back on it. (As a rule, remove pots and trays to water them, then place back into the propagator once drained).

The clear lid lets in the maximum amount of light and has generous vents, which are the keys to its success. Pic credit: Howard Walkerton Sahara Heating Mat from BioGreen is a really useful piece of kit.
The mat offers even heat distribution across a bench, and works best when placed on insulating material, such as polystyrene. It’s perfect for overwintering tender specimens, germinating seeds and taking cuttings.
If you are overwintering or propagating plants in an unheated greenhouse, then this mat will allow you to just heat one area, which will be far cheaper. Don’t forget to sign up for our monthly The English Gardener newsletter, bringing you all the growth your own advice you need throughout the year.
We’ve reviewed the top 10 heated propagators on the market, taking into account their design, capacity and much more. We’ve also included a detailed summary and FAQ guide at the bottom to answer any burning questions that you may have.
While windowsills can often provide ideal light conditions for successful propagation, they can also be cool and drought. Featuring 7 mini vented propagators, ideally sized for the most gardeners, the Super 7 allows the user to grow many plant varieties on just one unit.
This heated propagator has a tall lid to accommodate young plants as well as seedlings, with specially designed grooves for the placement of the grow lights. With 10,000 hours of life, the grow lights offer excellent value and the temperature control can be set precisely by 1C within its range.
This compact electric propagator has a 10 watt heated base, consuming one sixth of the power of a standard household light bulb. To aid healthy root development, the growing tray features ‘two tier’ drainage and capillary holes.
The bottom heat it provides is excellent for germination and with a relatively tall lid will accommodate seedlings as they grow into young plants. It has a power rating of 13 watts with the carbon fibre-heating element providing even heat distribution and a long life.
The seven mini propagators have clear lids (with adjustable vents) and will enable you to conveniently sow different varieties of seeds in each one. The heat generated from the base will soon kick your seed into action, with a window allowing a natural source of light.
There is always a slice of delicious Country Fare Glacé fruit cake on hand. Nothing marks the start of the gardening season like the first seed sowing of the year.
For the fastest seedlings in small batches you’ll want to treat them to the T&M Premium Seed Kit with its seven tray heated propagator. Both the flower and vegetable selections have something for pots, baskets and open soil.
We have ordered a terracotta bird nesting box and some roosting pockets for some young children to put up in their garden. Honestly they are really so good we each have two pairs to make sure we always have cozy feet every night.
Great British Florist is part of the Wiggly Wigglers organisation, and they offer the most beautiful bouquets and wreaths. This would be an absolutely fantastic gift for someone who just loves fresh flowers that haven’t been flown halfway round the world.
We are really looking forward to retreating into puzzle mode and forgetting the wintry weather outside. Over the past three years, this willing donkey has germinated hundreds of seeds and has become an old friend.
Admittedly I am not asking him to germinate really crusty coated seeds, such as those from the palm plant. An electric propagator is a good investment as it speeds up the germination process enormously.
Only accommodates one seed tray at a time, the next ten days will be a bit frantic but not as bad as it used to be. With tomatoes, I sow a couple of seeds in each cell, thinning them by removing the weaker seedlings a week after they have emerged.
In the olden days, each tray was prepared separately as requires and time permitted. The propagator could sit empty for several days before I found the time to fill the next tray of cells with compost and sow another batch of seeds.
I felt overwhelmed and Danny secretly fretted over the size of the autumn harvest of tomatoes. I mark each prepared tray with its eventual contents and put the relevant pack of seeds beside it.
I return home at lunchtime, make a sandwich for us both and check the propagator. As soon as the seeds emerge, the tray is whipped out, and I cart it down the garden to the greenhouse.
Usually I put an ordinary propagator lid over the seedlings for a day or two for extra protection, even in the greenhouse. The difference in temperature from sunny snug cottage windowsill to greenhouse can shock the seedlings and set them back.
Then I sow the seeds in the next tray and bring them back up to the cottage and the welcoming arms of our trusty C.P. I’ve found an 8 watt electric propagator similar to mine on Amazon.
