What to Do In the Garden This May

garden jobs to do in May

As we move into May, we get closer and closer to those warm summer days that we have all been craving! In preparation for your summer displays, there’s plenty of garden jobs to do in May.

From rigorous spring cleaning to planting and preparing your beds, borders and containers, there’s plenty to do this month. Follow this easy guide to help you start your monthly to-do list.

Hanging Baskets

hanging baskets are perfect for may planting

May is the perfect time to plant summer hanging baskets. Plant shorter plants toward the edge and taller plants in the middle.

Water your baskets regularly, preferably in the early morning or late evening so that the plants can soak up the most water before the sun appears!

Prune and Prepare

May is the perfect month to start dividing, pruning, and preparing your blooms and plants. Divide large clumps of daffodils, being careful not to disturb the bulbs too much.

Add support rings to your sweet peas to help them climb nice and tall. Divide Hostas, and prune spring-flowering shrubs.

Harvest Rhubarb

Now is the best time to harvest your Rhubarb plants. If this is your first year growing Rhubarb, then do not harvest until the second year of growth. Even then, only lightly harvest to avoid weakening the rhubarb crowns.

To harvest, pull the stalks when they are between 23-30cm long. Do not take more than half the stalks at any one time.

Earth Up Potatoes

Earthing up potatoes in May

Once your potato leaves have grown to around 10cm tall, it’s time to start the earthing process. This is to help the crops grow perfectly. This process is then repeated one or two times within 3 week intervals to help the tubers produce the best possible potato.

More Garden Jobs to do in May

  • Feel like starting a new project this month? Adding lawn edging around the garden can make the space feel tidier and well-maintained!
  • Plant summer bedding plants toward the end of month, if you live in southerly parts of the country (just to avoid late frosts, especially in northern England and Scotland).
  • Leave out seeds for birds that are nesting.
  • Mow lawns regularly, if needed.
  • Prune over-crowded and dead stems from early clematis plants once died back.

When to Cut Back Spring Flowers & Plants

Did you know that cutting back some spring flowers and plants helps them to perform better?

Spring is a great time of gardens, as all the remnants of winter finally disappears and we manage to see some sunshine. However, some plants and blooms need regular maintenance to help them thrive.

Herbaceous Perennials

If you’ve yet to trim your herbaceous perennials, then early spring (March onwards) is as good a time as any! Deadhead any seed-heads, dead leaves and stems to tidy up your garden borders. Throw them in a compost heap so that you can use it later on as mulch.

Bulbous Blooms

Spring bulbs are often the herald of the season. Daffodils, Hyacinths and tulips all fall into the spring flowers category, and although they look breathtaking when bloomed, they need maintaining to keep them that way. Leave your bulbs’ foliage for around eight weeks before cutting them back once died.

Bulbs photosynthesise, meaning that they store food and nutrients within the bulb which helps them to reappear the following year. If you cut these before they’ve had the chance, then they will struggle to regrow, leaving your displays looking sparse. For example, if your bulbs bloomed through March to April, then you should leave them standing until June or July.

Summer-flowering Shrubs

Although these aren’t spring flowering, summer-flowering shrubs should also be pruned throughout spring.

To promote a healthy regrowth before its flowering season, shrubs like Fuchsias should be pruned in early-mid spring. This will ensure that it creates an impressive display throughout its season. Simply cut back any of the previous year’s stems between one or two bud of the older wood frame.

Ornamental Grass

Ornamental grasses should be cut back in early-mid spring, depending on the variety. Grasses fall under two categories: Deciduous and Evergreen. The difference will determine how you prune them. Deciduous grasses will go a golden straw colour, and can be cut back entirely. Evergreens, however, do not need hard pruning, allowing you to simply remove what’s dead.

What Is a Perennial Plant?

echinacea - a variety of perennial plant

When you’re new to gardening, commonly used phrases and complicated jargon will boggle the mind. What’s an annual? What does ground-cover mean?

The most commonly asked question we receive from new gardeners is, what’s a perennial plant? If you also ask yourself this question, then we’re here to clear up your confusion.

What does ‘perennial’ mean?

The word ‘perennial’ is a blanket term for flowers that you plant in beds and borders but aren’t bulbs, shrubs, or trees. Perennials can also be evergreen or semi-evergreen plants.

Somewhat separate from perennials is the term herbaceous perennial. This refers to plants that are non-woody and will die back in autumn/winter, reappearing in the spring. A few examples include Geraniums, Sedums and Asters.

Put simply, perennials are plants that are non-woody (eg., rose bushes) that will reappear for many years after planted. Their time span will vary, depending on the plant. If they’re also evergreens, then their foliage will remain throughout the year, but will only blossom in specific seasons.

Perennial plant lupins

Which plants are perennials?

Agapanthus, Delphiniums, Echinacea and Lupins are all great examples of perennial plants. When buying perennials, you will usually buy them one season ahead of time. For example, if you’re buying perennials that will bloom in summer, you should buy them in early-mid spring.

On our website, we offer a broad range of perennial plants, perfect for adding colour to your garden. Here are some quick examples:

Echinacea magnus

When to prune acers

The best time to prune acers is when they’re dormant during November and December. But it doesn’t hurt to brush up on your knowledge to ensure you’re ready for when the time comes. The reason we prune acers whilst they are dormant is due to the sap they bleed when pruned which weakens the tree. It is also best to keep the pruning to a minimum as to keep the natural shape of the tree.

Acers are a great addition to any garden, and make an amazing centre piece for any garden. With leaves that turn beautiful shades of red, crimson, orange or yellow in Autumn. As slow growing and compact plants, acers are especially great for smaller gardens.

One thing to be aware of when planting acers is that they grow best in a sheltered position, and need to be protected from wind and frost.

How to prune

In order to keep this natural shape start by removing the badly-placed or crossing shoots to encourage the natural framework of the tree to grow. When reducing the width and height follow the long branches back to the side branch and prune.

Why we prune

Pruning is much more than sawing off branches. Pruning encourages growth, increases flowering and improves overall plant health. Here are a few others reasons to prune your trees:

  • Strengthens tree structure
  • Improves tree health
  • Reduces the risk of dead or weak branches

Important Notes

The key to making sure your acer continues to grow steadily and healthily is to only prune back to a well-placed side branch. Leaving it as a stub will make it susceptible to decay and dieback. Also remember to take out any dead, damaged or diseased wood.

Whether your acer is the main garden event or just a beautiful addition, keeping on top of its maintenance can ensure that it will take centre stage.

Time-saving Gardening Hacks for National Gardening Week

National Gardening Week is here! This national event, run by the Royal Horticultural Society (RHS), is to raise awareness of gardening, and to encourage more people to take part in this healthy and productive outdoor activity. We’re celebrating by sharing some of the best kept gardening hacks straight from the mouths of Parker’s team members. Keep reading to discover our top 5 time-saving gardening hacks.

Cut Flower Food Hack

Are your cut flowers in need of some TLC? Instead of buying flower food for your vase displays. Simply make sure to trim the stems every few days to keep the flowers fresh, and add in a teaspoon of sugar into the vase water. The sugar will not only help increase the number and size of open flowers, but it also prolongs the vase life.

Grow your own food with leftovers

Cutting vegetables and planning on throwing the scraps away? Think again! Fresh nutritious produce can be one of the most expensive buys from the supermarket. Luckily there are ways we can reduce this cost whilst experimenting with growing our own food at home. Scraps of potato, garlic bulbs and herbs can be grown in glass jars and water and transform into brand new plants. Great for the environment and your wallet.

Garden Planning Pot Hack

Put your plants in doubled pots, and then bury them at ground level. Whenever you fancy switching up your display, just lift out the top pot and slot in a different one. 

Cooking Water Fertiliser

The next time you boil or steam some vegetables, don’t pour the water down the drain. Once the water has cooled, you can pour the vegetable water in your garden to “fertilize” your plants instead of wasting it. Not only is it cost effective and resourceful, the fertilizer it provides for your plants gives them a more stable and steady growth period. 

Self-watering Plants

Planning on being away from your garden for a while? Fill a water bottle with water, leave the cap off, and quickly turn it upside down and push it a few inches into the soil. The water will slowly seep into the soil and keep it moist.

Building a Sensory Garden: Manchester Mind/ J. Parkers

We are happy to announce that J. Parkers have teamed up with the local mental health charity – Manchester Mind, to fund and construct their new sensory garden.

Throughout the course of the pandemic, our customers have shared so many stories about how gardening has benefited their mental health. With mental health close to the heart of our business, we decided to collaborate with a local charity that helps support better mental health. Manchester-based mental health charity Manchester Mind, provide support and training services for those struggling with mental health, including isolation, loneliness and food poverty. After discovering the amazing mental health work MM do, we had to reach out and offer our support.

At their Chorlton-based allotment, Manchester Mind staff and volunteers have been supporting the charity’s emergency food response, which produces meals for families experiencing food poverty in Manchester. At the allotment they are growing and harvesting food, that is then prepared by the catering team and used in the emergency response meals.

One thing sorely missing from the allotment, is a space to relax. After speaking with the Manchester Mind team, they revealed their goal to build a sensory garden. The aim of the garden would be to provide space for volunteers and staff to use for reflection and for one-to-one mental health support sessions. Therefore, to help achieve this goal, J. Parkers are now proudly partnering with Manchester Mind on the funding and construction of their sensory garden.

The Starting Point

A disused area at the back of the allotment will be the setting for the brand-new sensory garden. MM envision a calming space separate from the main plot. For the build, groundwork and planting days have been set out for J. Parker’s staff and Manchester Mind volunteers throughout spring to transform the space.

The Vision

The plan is to transform the desolate, unloved space in their allotment into a beautiful garden thriving with life. A large garden area will host seating areas, a solar fountain and a variety of scented plants. Additionally, a sheltered seating area is to be created as a private space for 1/1 support sessions. The grand opening date for the garden is June 21st 2021, which will celebrate the easing of lockdown restrictions.

Manchester Mind: Sensory Garden Garden (3D design)

One of the core values of Manchester Mind is that everyone deserves to be supported in their mental health needs. This new sensory garden will help provide a safe, relaxing space, all while helping make a difference for those in need mental health support in Manchester.

We will be providing updates on this project every few weeks, so stay tuned!

What is cross-pollination

The question of how to cross pollinate is a common one. But before learning how to, it’s best to learn what it is. Cross-pollination is not only exclusive to bees! It is a process of transferring pollen from the anther of one flower to the stigma of another flower. Cross-pollination can be used intentionally to create unique varieties of plants and vegetables.

What is cross-pollination

When one plant pollinates another variety, the two plants genetics combine to create a new variety. This new variety shares characteristics from both plants. A popular cross-pollination is for tomatoes, to create new and better varieties. This is intentional cross-pollination but it doesn’t always happen this way. In some instances, external forces play a hand in cross-pollination, like the wind or bees, carry pollen from one variety to another.

Common cross-pollinate misconceptions

Unlike flowers, not all plants can cross-pollinate easily. Cross-pollination within vegetables is less about the pollen, and has more to do with the species. For example, a cucumber could not cross-pollinate with a tomato as they are not the same species. But, it can happen between a broccoli and cauliflower.

Secondly, that the current harvest has been affected. This isn’t possible. Cross-pollination only affects the fruit of any seeds planted from that fruit. If think your harvest looks odd then it might be worth exploring other options such as pests and diseases before jumping to conclusions.

Controlling cross-pollination

Cross-pollination can be controlled, it just requires some extra steps. The easiest method is making sure to only grow one species in the garden as cross-pollination is unlikely to happen. If you want to grow multiple varieties you should determine if the plant you are growing is self pollinated or wind and insect pollinated. You can eliminate the chance of cross-pollination by planting different varieties of the same species at least 3m apart.

Whether is it intentional or not, cross-pollination isn’t always a bad thing. Your plants remain unaffected and you might even create a new variety that grows better and stronger than ever.

How to Keep Your Plants Cool During the Summer

Knowing how to cool plants down in the summer is an essential part of gardening through the season. Although some plants and flowers are drought resistant, many can struggle through particularly warm weather.

If your plants struggle to thrive throughout the summer months, then you’ve come to the right place! Here are some quick and simple ways to keep your plants cool during seasonal heatwaves.

Install Shade Cloth

Shade cloths are great for protecting crops through the season. You can buy these at most outdoor stores or online. Usually, they won’t be as big as the one pictured above.

Shade cloths are perfect for reflecting the heat of the sun away from your more delicate crops, such as peas and lettuce. The use of a shade cloth can help your crops to grow for longer, providing more produce!

The Best Time to Water Your Plants

You may not realise, but there are optimal times for watering your plants in summer. Although you may think they’re being hydrated when you do it midday, this can actually stunt the amount of water the root is getting.

As a rule of thumb, water your plants early in the morning, or in the evening once the sun has gone down. This allows the water to soak into the soil and nourishing the plant before the midday sun can dry it out.

Think About Your Plants Positioning

Potted plants are great for those that need a bit more shade. Pots can be moved anywhere around the garden, allowing you to find the shadiest areas throughout the day as the sun moves. For this reason, it’s best to grow drought-resistant plants in beds and borders, as they can resist a beat of heat.

Utilise Your Mulch

Mulch is a perfect way to cool plants down. Adding a bit of mulch, like leaves and grass cuttings, to the surface of the soil that surrounds the plant can actually cool the plant down.

Mulch also helps to retain moisture in the soil, and prevents weeds from appearing!
