No plants will survive very long without good watering, and it’s even more crucial for potted plants. They may not have the same access to rainwater, drainage or natural water reserves depending on where they are placed. So here is our handy infographic to remind you how to water pot plants for great growing!

If you’re looking to give your potted plants a fabulous new home, then you’re in luck. At Primrose we have an incredible selection of all kinds of planters available.

Caring for topiary

Growing topiary is one of the most magical arts you can master as a gardener. We all love the huge hedge animals and blooming box clouds. But maintaining and caring for topiary plants can be a lot of effort, so we’ve broken down the steps into our top tips. Keep this checklist handy as you get to work on your creations!

  1. Plant your high hedges wide as they’ll need a lot of root space.
  2. Topiary needs aerated soil so make sure it doesn’t become waterlogged. Use good compost, bark mulch and grit.
  3. Feed your plants with slow release fertiliser granules, and Growmore once every spring.
  4. Water regularly over summer and give a light watering in winter.
  5. Sterilise your cutting equipment with antibacterial spray to avoid transfer of disease.

Clipping topiary hedges

  1. Clips your plants into shape once or twice a year. During summer is the best time to do this – start after frost season is definitely over and finish up by September.
  2. Only cut the topiary on an overcast day as bright sunlight will scorch the leaves.
  3. Experts recommend trimming first with power tools for speed, then cleaning up with sharp shears.
  4. If you’re training growing branches then use soft twine so it doesn’t cut into the wood.
  5. Watch out for signs of disease. Box hedges are particularly affected with box blight and box suckers. Yew can be hit with phytophthora root rot.
  6. If your topiary has been neglected then hard prune it in early spring to get it back into shape. Then give it plenty of feed and mulch.

Topiary maintenance

Gardening, George, Greenhouses, Grow Your Own

Greenhouses are a staple of English gardens and an aspiration for all serious home-growers. But how do greenhouses work and what benefits do they provide for your plants and vegetables?

How do greenhouses work

What is a greenhouse?

A greenhouse is an external structure for growing plants, primarily made of a transparent material like glass or polycarbonate panels. They’re used in professional agriculture for growing huge volumes of crops, as well as by enthusiasts in their own back gardens. Inside you get a stable, warm environment that makes cultivating fruit and vegetables much easier throughout the year.

How do greenhouses work?

Greenhouses work by letting in as much light as possible then trapping this as thermal energy. The transparent walls and roof of the greenhouse allow all the visible rays of sunlight to pass through. This light heats up the air and objects (like the plants and soil) inside the greenhouse. But the glass also acts as an insulator, so this heat is locked inside the structure, keeping the temperatures warm all through the day.

Greenhouses are great at moderating a stable temperature. Matter within the greenhouse like soil and water absorb the thermal energy from sunlight and release it slowly, so they keep the greenhouse warm even after the sun sets. If the greenhouse contains lots of soil, the iron content within this has high enough thermal mass to regulate the temperature in this way with gradual heating and cooling throughout the day. Since the greenhouse is a closed structure, there is no breeze to disperse the warm air.

So the temperature remains constant, generally much warmer than the cold snaps we face outside, and your plants stay happy. They get all the sunlight they need to grow healthily and are sheltered from any harsh weather.

What are greenhouses used for?

Greenhouses effectively allow you to cheat the weather. In Britain we often have unreliable seasons at best, with cold winters and short summers. With a greenhouse you can extend the growing season – for example by sowing seeds earlier and growing vegetables like French beans and cucumbers for most of the year. Outside they would get too cold, but in the greenhouse they are protected.

The warmer environment in the greenhouse also means you can grow plants maladapted to our climate. Exotic species, such as melons and sweet potatoes, can thrive under the hot glass and delicate plants that would normally die in the winter frosts can be kept safe.

What are the benefits of having a greenhouse?

  • You can extend the growing season.
  • You can keep crops safe from pests within the physical structure, and so minimise the use of chemical pesticides you need to spray on produce.
  • You will protect plants from excessive temperatures (both cold and hot) and extreme variations in weather.
  • A greenhouse offers protection from strong winds which can damage delicate plants.
  • Shelter from rain and snow allows you to manually regulate how much water each plant is getting. This can be made easier with irrigation systems.
  • Temperatures can also be regulated with ventilation systems like auto vents to open windows and let air in, or shading to reduce light getting in during the peak of summer.
  • You can grow plants that wouldn’t normally survive in your climate.

Tips for keeping plants healthy in a greenhouse

While your plants will be kept warm and protected from the elements, you need to make sure they still get all that they need. Since they won’t receive water naturally from rain, you must remember to water regularly or set up an irrigation system to do this for you. It’s also worth setting up greenhouse guttering and a waterbutt to harvest rain falling on the roof.

During the summer months, the greenhouse can sometimes get too hot, which isn’t healthy for everything growing. So be sure to open a window or door if it gets too stuffy. You can also use a ventilation system like louvre windows or automatic vent arms to manage this for you. If excessive sunlight is causing the greenhouse to heat up uncontrollably, then hanging or spraying temporary shading on the roof windows can alleviate this.

Your greenhouse will also need taking care of to make sure it’s at its best year after year. This includes things like an annual deep clean, sterilising pots and checking for damage. You can read more in our greenhouse maintenance guide. Also make sure that you keep on top of pest control in your greenhouse.

Different types of greenhouse

Thankfully there’s not just one type of greenhouse to satisfy all gardeners. If you have space, then it’s worth getting the biggest freestanding one you can to maximise your growing area. But if space is limited then you can get a lean-to greenhouse attached to the side of your house, which offers the same robust frame and panels. For allotments and patio gardening, mini greenhouses and cold frames provide very compact space for crops, and can be portable too.

So we hope you now have a better understanding of how greenhouses work and why they’re such an invaluable treat for hobby gardeners and pros alike. If you’re interested in buying one for yourself, Primrose has a great range of high quality greenhouses available.

Animals, George, How To

Giving your pets the space to run around is one of the most important aspects of owning an animal. And if you have your own garden to do so then it’s worth making the most of it. Create a safe, secure environment where your pet dog can play freely so they’re happy and you have peace of mind. Here are some tips on how to make a dog-friendly garden.

How to Make A Dog-Friendly Garden

ADD

  • Security. The number one thing you can do to your garden is ensure all the fences, hedges and gates are secure. Board up any holes to prevent your pets escaping – or passing animals coming in. Screening rolls are an easy way to patch over gaps.
  • Robust plants. Dogs often jump through your flower beds so make sure the plants can survive a certain amount of trampling. Varieties such as rubella, marigolds and geraniums are good options.
  • Pathways. Another way to protect your plants is by creating walkways through them or growing in raised beds so your dog can explore without causing havok.
  • Dog rocks. Adding these handy pellets to your pooch’s drinking bowl can help prevent yellow patches on the lawn.
  • Space to play. Try to leave plenty of grassy area for your dog to chase its favourite ball and run around.

AVOID

  • Poisonous plants. Watch out for any of your favourite plants that can upset your dogs if they eat them. Examples include delphiniums, foxglove, ivy and rhododendron.
  • Harmful pesticides. Dogs will eat anything – including any toxic slug pellets you leave out in the flowerbeds.
  • Pond additives. Dogs will also drink anything – so be careful adding chemicals to ponds and other standing water.
  • Sharp objects. Birds often drop small shards of bone on the lawn, which can injure your dog’s insides if they chew them. So give the grass a once over, and keep an eye out if the mutt starts eating something suspicious.
  • Unprotected compost bins. Some of our food waste like grapes is poisonous to canines, so make sure you have a lid on your compost bin to keep off any inquisitive animals. Depending on how resourceful your dog is, you may need a lock too!
