Gardening jobs for May – Cut back herbaceous perennials  – The Chelsea Chop

When the growth of these perennials is getting rampant, now is a good time to cut back on these herbaceous perennials, such as phlox, sedums, catmint, Echinacea, and heleniums.  Usually done later in May (so called as it’s the time of the Chelsea flower show) these will help keep them under control, and tidy and give you extended blooms in Summer.  It can usually delay blooms for 4-6 weeks.

So how do you do it….

Well you have 2 options. Prune all of the plant, which will mean it is all delayed in its bloom or only prune ½ which will mean half with bloom in its natural season and the rest will bloom later giving you an extended flowering season.

Use sharp secateurs to make a sloping cut just above a leaf joint. Make sure your secateurs are clean its a good idea to sterilise them in a mixture of denatured alcohol and water so you don’t spread and potential diseases.

By chopping its stems back by a third or even up to a half of their length, you remove the weight that is holding them down and covering large areas of border, and encourage new growth that will give you an extended flowering period.

If you decide to only prune half, you can either do the left or right, front or back or prune every other stem. The position of the plant will help you decide which option is best.

Gardening jobs for May –  Saving water & water retention

As the cost of living is rising, every penny saved really does help. As summer is only round the corner and drier days are sure to be coming, the thought of watering our precious gardens can be really heart wrenching. Now is the time to be thinking of extra ways you can save water to use on your garden when it is dry. 

Have you got your water butts sorted? if you need a roof to drain from how about one off your welly rack storage shed?

Grey water

  • Use Domestic wastewater (known as ‘grey water’) in the garden. This may be from the kitchen, baths, basins and showers. If you have a way to get this stored for transport out of the house, this is a brilliant way to save water and water your plants. Household soaps and detergents are harmless to plants, but don’t use water containing bleaches or disinfectants as they will be harmful.

In the summer I always wash up into a bowl and then pour into a bucket or watering can by the back door ready for watering time in the evening.

It is also sensible to avoid using grey water on salads and other produce to be used without cooking.

Don’t store Grey water,  use it the same day. If stored, harmful organisms may form in the water and could be harmful to humans, pets and  plants. It will also start to smell quickly.

If plants are watered entirely with grey water during a very long dry spell, there is a danger that dissolved substances will build up in the soil, which can stop plants growing well. These will drain from the soil once there is a rain shower or if you alternate watering with stored rain water.

13th – 17th of May is Water saving week, where it is really highlighted how we can help to save water. You can check out advice and tips from Water Wise Here.

Water retention

  • Mulch your beds or use grass clippings around plants this will help to stop water evaporation from the soil and will stay moist longer. (try to avoid too much at the base of plants to avoid overheating.
  • Get weeding – make sure your plants aren’t fighting for water with weeds.
  • You could use capillary matts in the bottom of containers to help retain moisture in the soil.
  • Use perlite or vermiculite mixture into your soil. ( especially in containers)
  • Be creative – If you don’t have a roof to use, why not make one.

 You could combine this into an undercover storage area. Which would be perfect to house your welly rack, Or you could add this to the inside of your shed door. Make sure you have a water butt connected to your shed roof.

Welly storage racks are available in 2 pairs up to 5 pairs with the option with or without a shelf and also can be personalised.  Welly storage starts at £55 you can purchase yours here.

Job 3 –  What is Pinching out and why do it?

In most plants the top most bud the Apical bud, is the dominant bud and will suppress the other lower side buds (axillary buds) from growing. As this very top bud reaches for the sunlight it would grow into a long leggy plant with very few flowers. 

Pinching out the shoot tips (apical buds) of plants will stimulate the side shoots to grow and produce bushier plants with far more buds and hence more flowers. It will keep the plant in a more compact shape too. 

May is the time to pinch out bedding plants and young annuals, such as fuchsias and sweet peas to encourage bushier growth.

Gardening jobs for May – Trim Hawthorn hedges.


Depending on the type of hedges you have in your garden will dictate when you should trim and how often.  Some only need it once a year while others need 2 or 3 times a year.

Remember between March and August is bird nesting season, so take care to check your hedges for any activity before you get out your hedge trimmer.  If you have a bird nesting postpone the cut till they the young have hatched and flow the nest.

Do you know when to cut your hedges?

This is a great website to help you figure out when you should be trimming your hedges. Trimming at the wrong time of year can be detrimental as well as over trimming so care should be taken. Hedges are hard to replace if things go wrong so get it right 1st time, use the below website to help.


How to achieve Blooms all year round, complete your garden planner.

You can find your own FREE copy of my garden planner here. It is a great way to help achieve Blooms all year round.

How to use your Garden Planner

Take a walk around the garden and make a note of anything in bloom, where you have foliage and where you have gaps. Making notes on your garden planner, taking photos or videos is also really useful.

Now it’s time to do some research on what plants will be suitable for May and for the areas that are in need of plants. Make an assessment of the areas that need plants at this time of year making notes of the soil and position, which will then help with your research

Obviously if you are planning for blooms this month, you won’t see the blooms till next year, So if you are using my planner try to plan ahead to establish what you can sow or plant earlier to enjoy later in the year. This time next year hopefully you would have worked out a plan and been planting throughout the year.  You will then gradually create your garden to have some element of blooms all year round.  

Fill out your garden planner - then use seed packet organiser cards to get your seed box in order.

Useful Websites

I find these websites really helpful because they help you understand what plants will be suitable where. The Anglia bulb company has a great system where you can select when you want the bulbs to flower, So this is great for planning ahead. Don’t forget to check the conditions and suitability of the plant for your garden.
