0:00:00 > 0:00:02- Welcome to Garddio A Mwy.
0:00:02 > 0:00:04- I'm on the River Wnion...
0:00:04 > 0:00:09- ..to meet fishermen - who take an interest in gardening.
0:00:09 > 0:00:13- Iwan prepares - the greenhouse for winter.
0:00:14 > 0:00:17- Sioned starts planting - her new border.
0:00:17 > 0:00:23- Garden specialist Awen Jones - advises on popular house plants.
0:00:24 > 0:00:26- Welcome to Garddio A Mwy.
0:00:39 > 0:00:41- Today is a big day.
0:00:41 > 0:00:46- I'm planting - the first plants in the new border.
0:00:46 > 0:00:48- Last week...
0:00:48 > 0:00:51- ..I planted - three silver birch trees.
0:00:51 > 0:00:54- There are two large stumps, too.
0:00:56 > 0:01:00- I'm planting - the surrounding plants today.
0:01:00 > 0:01:04- I'm going to the garden centre - to see what they have.
0:01:08 > 0:01:13- To save money, I'll take cuttings - from the plants I already have...
0:01:14 > 0:01:17- ..and from friends' gardens.
0:01:17 > 0:01:21- But it's important - to treat yourself.
0:01:24 > 0:01:27- I'm also supporting - local businesses.
0:01:30 > 0:01:32- It's mid-October.
0:01:32 > 0:01:37- There are plenty of plants - to choose from this time of year.
0:01:37 > 0:01:40- The lovely autumnal colours...
0:01:40 > 0:01:44- ..makes it a pleasure - to visit a garden centre.
0:01:47 > 0:01:50- Look at this. - Isn't it wonderful?
0:01:51 > 0:01:53- What an amazing colour.
0:01:53 > 0:01:56- It's the Ozakazuki acer.
0:01:57 > 0:02:00- It's fantastic. - I'd love to take it home with me.
0:02:01 > 0:02:03- I can't.
0:02:03 > 0:02:08- Designing a new border requires - some sort of self-discipline!
0:02:15 > 0:02:18- I've sketched - what I want in the border.
0:02:19 > 0:02:23- I want to know - where the plants are going...
0:02:23 > 0:02:27- ..what to put on the edges...
0:02:27 > 0:02:29- ..and behind them...
0:02:29 > 0:02:33- ..and what will provide - height and interest.
0:02:33 > 0:02:36- Always remember to consider - the flower's shape.
0:02:37 > 0:02:42- You need contrast between - neighbouring plants.
0:02:42 > 0:02:47- This is my wish list of plants.
0:02:48 > 0:02:52- I might be disappointed - that not everything is here.
0:02:53 > 0:02:56- But I might - find a better alternative.
0:02:57 > 0:02:59- I'll have a look around.
0:03:11 > 0:03:17- This white anemone will contrast - with the grass.
0:03:17 > 0:03:19- I'm so glad it's here.
0:03:19 > 0:03:24- The Pennisetum is so nice, - I'll take both of them.
0:03:47 > 0:03:51- The Echinacea yellow spider - is lovely.
0:03:52 > 0:03:54- But the one I like is Green Envy.
0:04:01 > 0:04:05- I'd better pay for these - and go home to Pont Y Twr.
0:04:14 > 0:04:17- This isn't proper gardening.
0:04:17 > 0:04:21- But it's an important job - all gardeners have to tackle.
0:04:21 > 0:04:26- I'm sanding the wood, - giving it a coat of paint...
0:04:26 > 0:04:29- ..so the exterior - is ready for winter.
0:04:29 > 0:04:33- But I'm not just paying attention - to the exterior.
0:04:39 > 0:04:41- The weather has turned colder.
0:04:42 > 0:04:47- Look at the condensation - inside the greenhouse.
0:04:47 > 0:04:49- That's a sign autumn has arrived.
0:04:49 > 0:04:52- But the growing season hasn't ended.
0:04:52 > 0:04:56- The tomatoes in my greenhouse...
0:04:56 > 0:04:59- ..are not ripening - as quickly I'd like.
0:05:00 > 0:05:04- We have green peppers, too.
0:05:04 > 0:05:07- There are plenty of small ones.
0:05:08 > 0:05:12- There's plenty of life in it.
0:05:13 > 0:05:15- Here's an aubergine.
0:05:16 > 0:05:18- There's a big one here.
0:05:19 > 0:05:22- I've been late picking it.
0:05:22 > 0:05:26- There is more life to come.
0:05:26 > 0:05:30- There are six flowers.
0:05:31 > 0:05:34- Extending the season - a little longer...
0:05:34 > 0:05:37- ..will provide more vegetables.
0:05:37 > 0:05:40- How do we do that? - I'll show you.
0:05:42 > 0:05:45- I'm lining the inside - of the greenhouse.
0:05:45 > 0:05:48- You can use polycarbonate sheets.
0:05:49 > 0:05:52- They're effective - and easy to put up.
0:05:52 > 0:05:54- But they're expensive.
0:05:54 > 0:05:58- I'm using the old favourite...
0:05:58 > 0:06:00- ..bubble wrap.
0:06:18 > 0:06:20- It doesn't take long.
0:06:21 > 0:06:24- I've already done - half the greenhouse.
0:06:24 > 0:06:28- I do this because - the temperature drops at night.
0:06:28 > 0:06:30- For these plants to mature...
0:06:31 > 0:06:36- ..the temperature at night shouldn't - fall below six degrees Celsius.
0:06:36 > 0:06:38- That's the important threshold.
0:06:58 > 0:07:01- I've transformed the greenhouse.
0:07:02 > 0:07:05- It's like something - from the Barbarella set.
0:07:05 > 0:07:08- Another thing I want to do...
0:07:08 > 0:07:13- ..is bring the water butt - into the greenhouse.
0:07:13 > 0:07:16- The water warms up during the day.
0:07:17 > 0:07:21- At night, it slowly releases heat.
0:07:21 > 0:07:23- It's a very good idea.
0:07:24 > 0:07:27- But I can't save my two melons.
0:07:29 > 0:07:34- The problem is, I came out at night - with a head torch to prune.
0:07:35 > 0:07:40- I cut the melons' roots.
0:07:41 > 0:07:46- I should remove them, - but I don't have the heart.
0:07:50 > 0:07:55- Next, Meinir discusses one of - Britain's worst invasive plants.
0:07:56 > 0:08:00- I'm glad we don't have it - in the Pont Y Twr garden.
0:08:02 > 0:08:06- Japanese knotweed is a big threat...
0:08:07 > 0:08:10- ..to buildings and habitats.
0:08:10 > 0:08:15- It grows strongly - and spreads quickly.
0:08:15 > 0:08:17- I'm meeting Arwel and Gethin...
0:08:17 > 0:08:21- ..who are tackling - the problem in Meirionnydd.
0:08:23 > 0:08:29- As we're spraying weed killer, - protective clothing is needed.
0:08:29 > 0:08:34- They must spray annually - for a minimum of three years.
0:08:34 > 0:08:36- How did it arrive?
0:08:37 > 0:08:41- It's said that it's been here - since 1850.
0:08:43 > 0:08:47- It came from the Far East - to Kew Gardens.
0:08:47 > 0:08:49- It spread from there.
0:08:50 > 0:08:52- Let's go for it.
0:08:55 > 0:08:59- As you can see, - it covers the ground.
0:09:00 > 0:09:04- There is no growth under it. - It goes into rivers.
0:09:04 > 0:09:08- Nothing can bind the mud - so we lose the riverbank.
0:09:09 > 0:09:12- We lose a lot of ground - because of it.
0:09:12 > 0:09:15- I've seen pictures of it - growing through concrete.
0:09:16 > 0:09:19- It is so strong, - people can't believe what it can do.
0:09:20 > 0:09:22- If you have this at home...
0:09:23 > 0:09:24- ..what should you do?
0:09:25 > 0:09:28- The best thing is - to let people know about it.
0:09:29 > 0:09:32- Tell us about it - if you're within the National Park.
0:09:35 > 0:09:40- There are people, like me, - who don't believe in spraying.
0:09:40 > 0:09:43- But this leaves us no choice.
0:09:43 > 0:09:47- There is no other viable way, - other than spraying.
0:09:48 > 0:09:52- Cutting it with a strimmer - runs the risk of spreading it.
0:09:52 > 0:09:58- Only a tiny part is needed to catch - and create a new plant.
0:09:58 > 0:10:03- The other way is to dig it up - and burn it at a special site.
0:10:03 > 0:10:06- Liverpool is the closest to us.
0:10:07 > 0:10:11- Japanese knotweed - grows incredibly quickly...
0:10:11 > 0:10:15- ..as anyone who has it - in their garden would know.
0:10:15 > 0:10:20- It can grow 2.1 metres in weeks - in spring and is hard to destroy.
0:10:20 > 0:10:23- It spreads underground.
0:10:23 > 0:10:27- It has a rhizome, - an underground stem.
0:10:27 > 0:10:31- From this, - it takes root and grows shoots.
0:10:31 > 0:10:36- It can regrow from rhizome that's - less than one centimetre long.
0:10:37 > 0:10:41- Dolgellau Angling Association - and the National Park...
0:10:42 > 0:10:45- ..are working together - to get rid of knotweed.
0:10:45 > 0:10:49- They've paid for training - on how to spray the weed killer.
0:10:50 > 0:10:52- They do it in their own time.
0:10:53 > 0:10:56- We came together earlier this year.
0:10:56 > 0:10:59- Contractors do the high ground.
0:11:00 > 0:11:03- The Rotary Club has joined in.
0:11:03 > 0:11:08- Prince Albert Angling Society - from England is also taking part.
0:11:09 > 0:11:13- They have fishing rights on - the Wnion and Mawddach Rivers.
0:11:13 > 0:11:16- It's a community effort.
0:11:16 > 0:11:19- We're all together.
0:11:20 > 0:11:24- Why is Japanese knotweed - a problem to fishermen?
0:11:25 > 0:11:29- It prevents access to the riverbank.
0:11:30 > 0:11:33- Fishermen trample on it...
0:11:33 > 0:11:35- ..and pieces come off.
0:11:36 > 0:11:38- And then it spreads.
0:11:38 > 0:11:42- It goes downriver - and takes root again.
0:11:42 > 0:11:46- It suffocates everything under it.
0:11:47 > 0:11:52- In winter, - soil washes into the rivers.
0:11:52 > 0:11:55- It can cause problems for fish.
0:11:56 > 0:11:59- They bury eggs in gravel.
0:12:00 > 0:12:04- The soil covers it, suffocates - the eggs and they can't hatch.
0:12:05 > 0:12:06- It's quite a problem.
0:12:06 > 0:12:09- It's quite a problem.- - Yes, all along the river.
0:12:11 > 0:12:16- The battle against Japanese knotweed - won't be won overnight.
0:12:17 > 0:12:20- But with perseverance - and hard work...
0:12:20 > 0:12:22- ..it is possible.
0:12:22 > 0:12:22- .
0:12:26 > 0:12:26- Subtitles
0:12:26 > 0:12:28- Subtitles- - Subtitles
0:12:34 > 0:12:37- When planting a new border, - as I mentioned...
0:12:37 > 0:12:39- ..planning is important.
0:12:40 > 0:12:43- But when you bring - the plants home...
0:12:43 > 0:12:45- ..some things might change.
0:12:45 > 0:12:49- It's a good idea - to put plants in their place.
0:12:50 > 0:12:52- I'll start with the grass.
0:12:53 > 0:12:56- They'll provide height and interest.
0:12:57 > 0:13:01- You'll see their heads - in the breeze.
0:13:02 > 0:13:04- That looks very pretty.
0:13:06 > 0:13:09- They go half a metre apart.
0:13:12 > 0:13:14- I'm planting them in clusters.
0:13:15 > 0:13:20- Every plant will be in clusters - of three, five or seven.
0:13:20 > 0:13:24- Putting them here and there - looks rather untidy.
0:13:25 > 0:13:27- They look more natural together.
0:13:28 > 0:13:31- I've done that - in a few other places.
0:13:31 > 0:13:34- The sedums were - three plants originally.
0:13:35 > 0:13:39- Over the years, - it's become one big plant.
0:13:39 > 0:13:43- I also did that with hebes. - I planted five small ones.
0:13:43 > 0:13:48- In the last two years, they've - filled out and look like one plant.
0:13:48 > 0:13:52- I hope to achieve - a natural look here too.
0:13:53 > 0:13:56- Next, the pink anemone - goes over there.
0:13:58 > 0:14:00- I'm putting them here...
0:14:01 > 0:14:05- ..because I like seeing - the wood behind them.
0:14:06 > 0:14:08- One more.
0:14:15 > 0:14:20- I'm putting this special - Echinacea behind the bench.
0:14:31 > 0:14:33- Echinacea really likes the sun.
0:14:33 > 0:14:38- This corner gets a lot of sun in the - morning, a little in the afternoon.
0:14:39 > 0:14:42- It's over there - by the end of the afternoon.
0:14:42 > 0:14:45- I hope this area suits them.
0:14:45 > 0:14:48- This is only the first step.
0:14:48 > 0:14:53- It's surprising how many plants - you need to fill a border.
0:14:53 > 0:14:55- But that's not the aim.
0:14:55 > 0:14:59- I hope these plants - will grow to fill this corner.
0:15:00 > 0:15:04- I'll divide a lot of the garden's - plants to put round the edges.
0:15:05 > 0:15:07- Now, the rest of the plants!
0:15:35 > 0:15:37- I've started the work.
0:15:37 > 0:15:39- These are garden plants, of course.
0:15:39 > 0:15:43- But houseplants - also give a lot of pleasure.
0:15:43 > 0:15:47- Awen Jones gives us some advice, - beginning with orchids.
0:15:48 > 0:15:52- To make sure an orchid - thrives in your house...
0:15:52 > 0:15:54- ..look out for a few things.
0:15:54 > 0:15:57- Make sure the leaves - are green and healthy.
0:15:57 > 0:16:02- If the lower leaves look yellow - and have brown or black marks...
0:16:02 > 0:16:07- ..they've had a serious - watering problem at one point.
0:16:07 > 0:16:09- Leave it in the shop.
0:16:10 > 0:16:12- Then look at the buds.
0:16:13 > 0:16:16- They should be green and healthy...
0:16:18 > 0:16:21- ..and look soundly - attached to the stem.
0:16:21 > 0:16:26- You'll know you'll have a good - display for weeks, if not months.
0:16:26 > 0:16:30- Watering depends - on how warm the house is.
0:16:31 > 0:16:33- Once a week is usually enough.
0:16:34 > 0:16:36- My tip is look at the roots.
0:16:36 > 0:16:40- If the roots are a silvery colour, - they need water.
0:16:41 > 0:16:44- Then you'll see them turning green.
0:16:45 > 0:16:49- Wait for them to turn a little - silvery before watering again.
0:16:49 > 0:16:53- You can water it - as you do with houseplants.
0:16:53 > 0:16:57- Or soak it in water - and let it drain on one side.
0:16:57 > 0:17:01- Don't use give it - ordinary houseplant food.
0:17:01 > 0:17:03- It's too strong.
0:17:03 > 0:17:06- Use orchid food.
0:17:06 > 0:17:08- They're found everywhere now.
0:17:09 > 0:17:12- Two plant groups that - don't receive the right care...
0:17:12 > 0:17:16- ..are cactus and carnivorous plants.
0:17:17 > 0:17:18- First, the cactus.
0:17:19 > 0:17:22- Remember they're living plants.
0:17:22 > 0:17:26- Although they don't - seem to need much water...
0:17:27 > 0:17:30- ..they do need watering to thrive.
0:17:30 > 0:17:34- From spring to autumn, water - them and give them cactus food.
0:17:35 > 0:17:37- But ignore them in winter.
0:17:37 > 0:17:41- In spring, - they'll have lovely flowers.
0:17:41 > 0:17:43- Now, my favourites...
0:17:44 > 0:17:46- ..carnivorous plants.
0:17:46 > 0:17:48- They're very popular.
0:17:49 > 0:17:52- The best known is the Venus flytrap.
0:17:53 > 0:17:56- There are a few tricks - to keep them healthy.
0:17:57 > 0:17:59- Make sure they're in a saucer...
0:17:59 > 0:18:04- ..with at least one or two - centimetres of rainwater.
0:18:05 > 0:18:07- Don't give them any plant food.
0:18:08 > 0:18:12- If you can, catch fresh insects, - the fresher the better.
0:18:13 > 0:18:16- You might have to wiggle them - to make the trap shut.
0:18:17 > 0:18:18- But they appreciate it.
0:18:19 > 0:18:23- The Sarracenia - is increasing in popularity.
0:18:24 > 0:18:26- I'm very fond of them.
0:18:26 > 0:18:29- They have tall, graceful trumpets.
0:18:30 > 0:18:32- This is how they catch insects.
0:18:33 > 0:18:36- You often see dew on the trap's lip.
0:18:38 > 0:18:40- That attracts insects.
0:18:41 > 0:18:44- They get a bit drunk and go in.
0:18:45 > 0:18:47- They're eaten in the trap.
0:18:48 > 0:18:51- Treat these in a similar way.
0:18:51 > 0:18:55- They're dying back now, - to preserve strength in the pot.
0:18:56 > 0:18:58- It's one of my favourites.
0:18:58 > 0:19:02- It has a marvellous range - of colour and types.
0:19:03 > 0:19:08- It's one of nature's marvels. - I can't help really liking them!
0:19:15 > 0:19:19- Seeing grapes grow - in the sunshine is very enjoyable.
0:19:20 > 0:19:24- I never thought I'd pick - fresh grapes in the garden.
0:19:27 > 0:19:29- They're not ripe.
0:19:29 > 0:19:31- That's the problem in Wales.
0:19:31 > 0:19:34- The growing season - isn't quite long enough.
0:19:35 > 0:19:37- They've grown well.
0:19:37 > 0:19:41- But they need three or four - more weeks to ripen.
0:19:43 > 0:19:44- I'll remove these.
0:19:45 > 0:19:48- They'll go in the polytunnel I hope, - if Sioned lets me.
0:19:50 > 0:19:55- But blackcurrants - certainly don't need warmth.
0:19:55 > 0:19:59- They're very easy to grow, - full of Vitamin C...
0:19:59 > 0:20:02- ..and the fruits freeze very well.
0:20:03 > 0:20:07- This time of year, you think - of either planting blackcurrants...
0:20:08 > 0:20:10- ..or pruning your plants.
0:20:10 > 0:20:12- Early winter is the time.
0:20:12 > 0:20:15- How do we prune blackcurrants?
0:20:15 > 0:20:20- We talked about summer raspberries - fruiting on two-year-old canes.
0:20:20 > 0:20:22- Blackcurrants are just the same.
0:20:23 > 0:20:27- I'm going to remove the branches - that bore fruit this year.
0:20:27 > 0:20:31- It's easy to tell which ones - they are. Look at these two.
0:20:32 > 0:20:35- The leaves on this branch - have wilted.
0:20:36 > 0:20:40- The bark's colour is slightly - different and darker.
0:20:41 > 0:20:43- And this makes it obvious.
0:20:44 > 0:20:49- You'll see where - blackcurrants grew this year.
0:20:50 > 0:20:53- I know which branch - bore fruit this year.
0:20:54 > 0:20:56- I'll follow it down the stem...
0:20:57 > 0:21:02- ..until I reach another branch, - which is clearly new.
0:21:04 > 0:21:07- This will bear fruit next year.
0:21:09 > 0:21:11- I'll get rid of the other one.
0:21:12 > 0:21:16- Cut at an angle, - quite close to the other one.
0:21:16 > 0:21:18- And that's it.
0:21:18 > 0:21:22- Once all the old wood has gone, - I'll have a better picture...
0:21:22 > 0:21:26- ..of the branches - that will bear fruit next year.
0:21:26 > 0:21:31- I want to take cuttings. - It's very easy with blackcurrants.
0:21:31 > 0:21:34- You use this year's growth for this.
0:21:35 > 0:21:39- I won't cut too much, - or I won't have any fruit next year.
0:21:39 > 0:21:43- I'm sure this bush is big enough - to spare five or six plants.
0:21:44 > 0:21:48- If you've never taken cuttings, - I really recommend it.
0:21:48 > 0:21:53- Blackcurrants are one of the easiest - plants for taking cuttings.
0:21:53 > 0:21:58- Take between eight to twelve - inches of the new growth.
0:21:59 > 0:22:01- Remove the leaves...
0:22:04 > 0:22:07- ..and the top ones too.
0:22:09 > 0:22:13- There are plenty - of buds on the stem.
0:22:13 > 0:22:15- I don't want them all...
0:22:15 > 0:22:17- ..so I remove most of them.
0:22:19 > 0:22:22- I'll leave two or three on the end.
0:22:24 > 0:22:26- Cut off the growth at the end.
0:22:28 > 0:22:30- I'm left with three buds.
0:22:31 > 0:22:36- Now, all I do is plant it - in cutting compost.
0:22:36 > 0:22:41- I've mixed it with plenty of sand, - so the soil is very light.
0:22:41 > 0:22:45- We don't want the young stems - sitting in wet soil.
0:22:45 > 0:22:48- They'd rot, - because they have no roots.
0:22:48 > 0:22:50- But the roots soon grow.
0:22:51 > 0:22:52- In they go.
0:22:53 > 0:22:55- Water them well.
0:23:03 > 0:23:07- These will go - in the greenhouse over winter.
0:23:07 > 0:23:10- They'll be ready - to plant out next spring.
0:23:21 > 0:23:25- That's it for another week. - Thanks joining us again.
0:23:25 > 0:23:28- We had our first frost today.
0:23:28 > 0:23:31- Keep an eye on the weather forecast.
0:23:31 > 0:23:34- Put tender plants - in the greenhouse...
0:23:34 > 0:23:37- ..or put fleece - round any still in the garden.
0:23:37 > 0:23:40- Until next week, - enjoy the gardening.
