If you don’t have your own small animal audience, store-bought is fine.

Exciting news folks! Primrose has recently got in a whole new selection of terrarium making tools, the first on the site made specifically for closed-system terrariums! Well since they’re so new, and terrariums are finally making the come back they deserve, I went and wrote up the journey through creating my own closed-system terrarium.

You will need

All of this and a good dash of patience.

The sets we have online also include a very handy shovel and rake set that extends to reach the bottom of your jar, these are indispensable if you have a very deep terrarium! (Although you could always wrap some wire around a fork and a spoon, no judgement here.)

If possible, it’s recommended to find a piece of plastic mesh to help keep the stone and soil layer separate, but don’t worry if you can’t get hold of any, I didn’t use it in my terrarium.

Also handy:

  • A lot of newspaper to work on (it gets messy!)
  • A funnel (I made one out of a cereal packet)
  • Scissors (for pruning if needed)
  • Small hand trowel (for removing soil from roots)

And last but not least, the plants and accessories you want in the terrarium.

These are the two species I used, Tradescantia Purple Passion at the front and a Chlorophytum Comosum behind.

The process

The idea of a closed terrarium is to create an ecosystem that will sustain itself. Both the plants and soil release moisture that becomes water vapour, and condenses against the walls of the terrarium during the warm daylight, falling back to the soil in the cooler evenings. This creation of an enclosed watering system is what will keep your terrarium growing, but just throwing dirt and plants at it isn’t going to work, an irrigation system is needed to stop the soil from rotting under too much water.

At this point you’ll want to grab the funnel, or if you’re on a budget, make one out of cardboard or paper to make for easier application of the materials.

First pour in a layer of small stones, pebbles, or gravel. There’s no hard and fast measurement as it depends on what size receptacle you’re using, a good rule to stick to is one-quarter stones to three-quarters soil. Remember this layer has to be deep enough to stop any pooling water from sitting in the soil.

I’d highly recommend checking out this video on youtube for a visual representation: https://www.youtube.com/watch?v=7Lg4tzkHgVo

Check your terrarium from all angles, sometimes it’s hard to judge the level of coverage with curved glass.

Next is activated charcoal. This is an integral ingredient in the tasty soup that is your closed terrarium. It absorbs chemicals in the soil, water, and air that could otherwise build up over time and damage the plants. Charcoal also cleans up unpleasant odours that are released from the decomposing soil and helps stop mildew forming.

You don’t need a whole layer of the stuff, but make sure there’s a good handful being placed in, it’s going to do a lot of work after all!

If you’ve been able to source some plastic mesh, now is the time to cut it to shape, fold it up and pop it in. You’ll need some long tools to push and pull it into place, and then you can add the substrate. (Note that the charcoal seems fine both above and below the mesh layer.) Again, if you don’t have a mesh layer don’t worry! You can still power on!

Okay, let’s layer up some soil! You’ll need a decent amount, remember we’re working to approx one-quarter stones to three-quarters substrate. Don’t worry if your measurements aren’t perfect, it’s all a learning process!

Make some small divots for the plants to sit in, and let’s move on to prepping some plants!

Easy as 1, 2, 3!

Plant choices

A closed terrarium is a specific type of environment. There’s a lot of damp warmth in there, and if left in direct sunlight, the refraction of the glass will cook everything inside. So we need moisture-loving, low light-thriving, quite small plants. Which admittedly cuts down our options somewhat, but here are some plants that I’ve discovered-

Small ferns will help fill out any space, and they’re relatively easy to come by. Try and find a miniature variety if you can, as some ferns can grow pretty big.

Some that come recommended:

Peperomia, Maidenhair fern, Pteris, and Adiantum. I chose a variegated fern to place in mine, the pot I purchased had three separate plants in it so I picked out the smallest to place in my also quite small terrarium.

Soleirolia variants are perfect as well, and have a variety of amusing names such as, mind-your-own-business, baby’s tears, angel’s tears, friendship plant and Irish moss. (It is in fact, not a moss, but a plant from the nettle family.)

Tradescantia- also known as Spiderwort, is another plant that does well in humid climates. There are a lot of variants though, and I’d recommend staying away from any that are flowering as they will wilt and die quickly in the terrarium. I chose a Tradescantia Purple Passion to place in mine.

Other tropical foliage such as Dizygotheca and Neoregelia ‘fireball’ enjoy a humid environment, making them other possibilities for your display.

To finish it off I would recommend some moss. I took a trowel and dug some out of my garden. Moss is a great way to fill out your terrarium, it helps to cover bare soil and brings more diversity into the jar.

Trixie spent the whole time trying to eat my plants and the moss. Thanks Trix.

Preparing plants

This section entirely depends on what container you’re using for your terrarium, but for brevity’s sake I’m going to assume you’re using the same line of terrariums that I am, and in that case you’ve got some trimming to do. The opening of the bottle is a lot smaller than you first think, so you’ll need to carefully extract the plants from their pots, and gently scrape or shake off most of the soil around the roots so you can fit it through the top. This is where having another container or a lot of newspaper down comes in handy to catch all the soil!

Move the plant around after it’s fallen inside, and make sure you push soil back around the roots when you’ve confirmed the placement.

Now is a good time to consider the layout of your terrarium. Instagram and Pinterest are great sources of inspiration, just make sure whatever you use is small enough to fit!

In my terrarium I used some old chunky sticks to create a divide in the middle, putting the fern one side and the tradescantia on the other, with moss liberally applied all around. To finish it off, I added some more height with a mossy stick reaching up through the bottle, remember to consider your layers to make for a more visually interesting display!

Here’s my finished terrarium! I’m very pleased with how it turned out, and it didn’t take more than about half an hour to put together!

Finishing off

Before adding the cork, make sure you give your terrarium a good spritz with a spray bottle, or pour a little water down the side. You don’t need to add the cork straight away – allow the bottle to stand for a day to let the plants settle, and for the first week or so, take the cork off for a few hours every day. This allows you to adjust the water, and allows the plants to breathe and accumulate to their new closed-system environment a little easier.

Keep your terrarium out of direct sunlight, and rotate it every day or so to allow all sides to soak up some heat.

And here’s my beauty after 2 weeks! The tiny wild clover in the moss are loving it!

Troubleshooting and the future

There’s always the fear that your terrarium won’t last the weekend. Fear not! If you’ve used the right plants and followed the guide you should be safe. One thing to bear in mind is the water cycle, moisture should build up over the day, then drip back down to the soil overnight. If there is too much condensation then plants might start to rot, so remove the cork and allow it to dry out a little. If there’s no moisture on the sides by late afternoon, it may need a spritz of water to keep the cycle going.

If it does unfortunately go wrong, there’s no shame in calling it a day, dumping it all out and starting again. We all have to start somewhere, and I’m sure your next terrarium will look amazing!

If you do make up one of our terrariums, be sure to snap a photo and send it in!

Clematis are immensely popular climbing plants, flowering from late winter to late summer, depending on the variety. Grow them on walls, pergolas, in containers, scrambling through trees and shrubs or left sprawling along the soil as unusual ground cover.

Planting guide

If planting next to a wall or fence, dig the hole at least 60cm (2 feet) away and train the plant along the cane. Clematis perform best when their roots are shaded – either plant in front of them or cover the area with a mulch of stones or pebbles. They need moisture-retentive, but well-drained soil, in full sun or partial shade.

Dig a hole twice as wide as the plant’s pot and half as deep again. Add well rotted organic matter to the bottom of the hole and a handful of general granular fertiliser.

After soaking the plant in its pot, remove it together with its cane. Tease out some of the roots and place in the hole.

Plant large-flowered cultivars that bloom in May/June with their root balls 5-8cm (2-3in) below the soil surface. Herbaceous and evergreen species can be planted with the crown at soil level. Fill the hole with a mixture of soil and compost and water in well.

If planting in containers, choose a smaller-growing cultivar, using a pot at least 45cm (18in) deep and wide with a soil-based potting compost such as John Innes No 2.

Care

In late winter or early spring, apply a potassium-rich fertiliser (such as rose fertiliser) and mulch afterwards with well-rotted manure, leafmould or compost. Water regularly during dry weather in the first few seasons.

For container plants, top dress each spring by replacing the top 2.5cm (1 inch) of soil with fresh potting compost. Protect roots in winter from frost by wrapping the pot in bubble wrap.

Water thoroughly and feed monthly during the growing season.

 

Pruning

Clematis is notorious for being difficult to prune but that’s not the case, as long as you know which pruning group it belongs to (based on when it flowers).

When first planted, cut all clematis back to 15-30cm (6”-1ft) from soil level in February or March, cutting just above a bud. This will encourage branching and more flowers.

Pruning groups:

Group 1 – flowering in spring on shoots produced the previous season, such as C. montana, C. cirrhosa, C. alpina. Prune just after flowering in mid- to late spring if needed – no regular pruning is essential.

Group 2 – large-flowered hybrids, blooming May/June. Prune in February/March and after the first flush of flowers in early summer. The aim is to keep a framework of old wood and promote new shoots.

Group 3 – plants that flower on that season’s growth and herbaceous clematis. Cut back hard in February/March 15-30cm (6in-1ft) from soil level to healthy buds. If left unpruned, they will continue growing from where they left off the previous season, flowering well above eye level and with a bare base.

Small-flowered clematis with attractive seedheads can just be trimmed back to the main framework of branches.

Rhododendrons and azaleas usually bear their spectacular, large, often scented flowers in spring – but do you know the difference between the two?

Well, both are in the genus Rhododendron –  but azaleas can be distinguished by having five stamens per flower (one per lobe), whereas rhododendrons have 10 or more (two per lobe). Azaleas can be deciduous or evergreen but rhododendrons are all evergreen. Finally there is a difference in size. Azaleas are small to medium shrubs – rhododendrons range from prostrate shrubs to huge trees.

Within this guide you will find information about some of the different varieties of rhododendron and azaleas, as well as information about how to successfully plant and maintain your own.

Main Species

There are more than 28,000 rhododendron or azalea hybrids, as the plants readily cross breed. However, here are the most popular varieties for gardeners:

  • Hybrids or hardy hybrids: What gardeners would consider a ‘traditional’ rhododendron with large flower trusses, some scented, blooming anywhere between January until July – often growing very large.
  • Dwarf rhododendrons: Mainly alpine varieties, ranging from 20cm-80cm, flowering in April.
  • Yakushimanum: Mound-shaped plants reaching 80-100cm, often with unusual leaves. Many brilliant flower colours available.
  • Williamsianum: Unusual rounded leaves, 80-100cm.
  • Deciduous azaleas: Sun lovers, growing up to 150cm, often scented, (especially R. luteum) with rich autumn foliage. They can be divided into Species (Sciadorhodion, Pentanthera, Rhodora, Sinensi or Brachycalyx); Ghent (the oldest hybrid group with multiple small flowers); Knaphill (large flowered hybrids, some of which are scented); Mollis (earlier flowering, more compact and spreading); Rustica (small double flowers, some scented). Other deciduous azaleas include Pratt hybrids, viscosum, occidentale and the Northern Lights series.
  • Evergreen azaleas: Small, slow-growers, suitable for pots, up to 75cm, some are prostrate in habit, with autumn colour. Flowering season is usually May.

Planting

Choose a sheltered site with dappled shade, however, dwarf alpine species will tolerate full sun. Avoid sites exposed to early morning sun in spring, as this may damage frosted flowers.

The most important factor deciding whether rhododendrons or azaleas will grow well in your garden is the pH of your soil. They must have moist but well-drained, acid soil between pH 5.0 and 6.0 that is rich in organic matter. Reducing soil pH is not easy.

October or March/April are the best times for planting – dig in acidic organic matter before you begin (leafmould, rotting pine needles or composted bracken will work well). Don’t just concentrate on the planting hole – mix well around the surrounding soil. Don’t plant deeply, as rhododendrons are surface rooters. Apply a loose 8cm mulch of acidic organic material and water well to finish.

Care

To keep your plants performing at their best, in spring, apply slow-release ericaceous fertiliser and renew the acidic mulch and keep well watered.

Rhododendrons grow best in areas of high rainfall, which is naturally slightly acidic. Using tap water, especially in hard water districts, is not good for the plant as it contains too much calcium which reduces the acidity around the plant’s roots. However, if rain water runs out, tap water is OK to use for a month or so in summer.

Rhododendrons don’t require pruning apart from removing dead wood and deadheading if practical. If the plant outgrows its space, cutting back is tolerated best from deciduous azaleas and rough-barked rhododendrons. After cutting back, mulch, feed and keep well watered.

Growing in Containers

If you have alkaline soil, grow rhododendrons and azaleas as container plants. Use ericaceous loam-based compost and repot every other year into fresh compost in spring. When not fully repotting, top dress the top 5cm of growing medium with fresh compost.

Common Problems

Most problems with rhododendrons and azaleas stem from the soil being too alkaline, drought or other extreme weather conditions. Here are signs to look out for:

  • Non-flowering and bud drop: Flower buds actually start forming in late summer – dry conditions at this time can lead to a total bud formation failure or a partial formation, causing buds to dry up and dropping unopened in spring. Mulch and water thoroughly and regularly during dry periods in summer.
  • Leaf drop: Older leaves droop and roll, then drop off, following extreme moisture conditions – drought or waterlogging. Newer leaves show browning at the leaf tip or edge. However, it is normal for the shrub to shed some older leaves in spring and summer.
  • Leaf droop: Usually a response to severe cold, but they usually recover.
  • Leaf scorch/flower damage: Often caused by windy, cold or wet weather.
  • Yellowing foliage: Caused by nutrient deficiency known as chlorosis, an iron deficiency caused by high alkalinity in the soil.
  • Pests: Vine weevil can be a nuisance for container-grown plants, as can rhododendron leafhopper and scale insects.
  • Diseases: Relatively uncommon are bud blast, azalea gall and honey fungus.

Over 200,000 revellers will descend upon Worthy Farm for the annual Glastonbury Festival today. Whilst they will be rocking out to the likes of Ed Sheeran, it is also inevitable that they will encounter a lot of rain and mud too. Yes I know, we’re in a heatwave, but it’s Glastonbury – it ALWAYS rains. Not to mention the fact they will be unable to shower for almost a week, will be slogging it on a camping mat and will be void of all the amenities you appreciate with every day life.

So, how do you enjoy Glastonbury without actually slogging it with the masses? Well bring Glastonbury to your garden of course! Whether you’re listening on the radio or watching on the TV, you can easily recreate that feeling of being there.

We’ve a few products to make your ‘Glastonbury Garden’ even better.

Gazebos
Recreate that feeling of being in a tent, but with a lot more space and freedom. I’d recommend the yellow party tent; it’s funky colours will help create that festive vibe. The majority of our gazebos are waterproof too, so you don’t have to worry about getting soaked!

Outdoor Rugs
Relax in comfort with a vibrant outdoor rug. Not only are they 100% waterproof, but they’re also really easy to clean thanks to their polypropylene material. You can sprawl out, and use these as a picnic blanket if you wish also (or even as a place for your pets to lay and join you).

BBQs
When you’re at a festival, chances are you’ll either be eating beans off a small stove, throwing gone-off burgers onto a disposable BBQ or will simply divulge in a liquid-only diet. However, now you have the opportunity to cook up a fresh feast, and eat like royalty in comparison to the campers.

Outdoor Heating
Leading on from the delight off freshly cooked, warm food, why not keep yourself warm too in the cool evenings? Avoid layering up and wrapping yourself in blankets, and opt for a heater or firepit instead. It will provide you and your guests with ultimate warmth throughout the evening, and no longer will you have to worry about the cold British weather. If you opt for a firepit, you can recreate that festival feeling of sitting round a campfire, singing to your hearts content too!

Solar Lighting
Add an enchanting glow to your Glastonbury Garden set up with solar lighting. Whether you want to stake them into the ground, or hang them up on your gazebo (or nearby trees), you can create a beautiful scene which will help guide you back your bed when it’s getting dark.

Bean Bags
Perfect for lounging around in your garden, why not sit back and relax whilst you enjoy the sound of  Barry Gibb or Stormze. Why stand up on your feet all day, draining yourself at the main stage when you can sit back and crack open a cold one. No more sore feet. No uncomfy bottoms.
