Top Tips for June

A- | A+

Nothing beats the fresh produce that becomes available this month, and if you’ve grown it yourself, so much the better! New potatoes, salad and strawberries – all should be ready to harvest now, so enjoy the fruits of your labours, along with the longer evenings and (hopefully) sunshine!

If time is limited in the garden this month, here are our Top Ten tips:

1) Water your plants regularly (bedding plants will need it once a day and shrubs, roses and perennials every other day) and feed them with a slow release fertiliser every few months.
2) Prune spring flowering shrubs.
3) Plant roses and remember to feed well with a slow release rose fertiliser.
4) Plant out your bedding.
5) Hoe borders regularly to keep down weeds.
6) Mow lawns at least once a week.
7) Stake tall plants.
8) Harvest lettuce, radish and other salad crops.
9) Harvest strawberries and raspberries.
10) Thin out tree fruits.

If you have a little more time to spare…

If you haven’t already, plant up your beds, hanging baskets and containers with summer bedding! Add water retaining gel and slow release fertiliser (such as Osmocote) to the potting compost which will assist/reduce the need for watering during the season.

Clip vigorous rock garden plants such as aubrieta and alyssum with shears once the flowers are over, to keep them compact and free-flowering. Remember to water sweet peas and either pick the flowers regularly or remove the seed heads to ensure the plants continue to flower.

Prune spring flowering shrubs to prevent them overgrowing. Some variegated shrubs have a tendency to revert to green, these green shoots grow strongly and can take over the plant – cut them out wherever you see them. Prune deciduous shrubs, cutting out shoots that have just flowered in order to encourage strong new growth for next year.

Don’t forget about Roses. We have a fabulous selection in store at Coolings now with great offers available for our Coolings Family Members. Roses appreciate good rich soil, so plant with Coolings Tree and Shrub Compost or well-rotted farmyard manure. We also recommend Rootgrow with friendly mycorrhizal fungi to give your roses a boost throughout their lifetime. After planting, feed through summer with a slow release rose fertilliser such as Toprose or David Austin Rose Food to promote healthy foliage and generous flowering. Remove faded blooms to promote repeat flowering. Plants can be sprayed with Rose Clear to control pest and disease problems should they occur.

Water, water, water and feed your plants! All recently planted plants – especially bedding – and plants in containers and baskets will appreciate a good soak everyday and a regular meal every month to keep them growing well. Use collected rainwater where possible.



It’s a good time to spruce up your garden furniture ready for Summer BBQs and entertaining. If like me, your BBQ is in need of a very good clean and your furniture could do with a wash down/varnish – now’s the time to do it!

Keep on top of weeds by hoeing regularly in dry conditions. June 21st is the longest day of 2018, and the extra light and warmth encourages the garden to have a growth spurt.

Stake tall perennials to prevent wind damage to flower spikes.

Train and tie in Sweet Peas to supports to encourage them to climb for a good display.

Once new plantings have established, you can start to sock new fish ponds with fish. Start stocking and feeding when the water is warm. Continue to remove blanketweed from ponds by twirling it around on a stick.

Trim hedges frequently to allow wildlife to shelter and feed.

Keep your birdbaths topped up.

Thin tree fruits to improve fruit size, quality and flavour and to help prevent branches from breaking. Thinning also helps to prevent biennial bearing (heavy crops one year and nothing the next). Protect soft fruits by netting the crop just before it ripens. Pick the fruit when it is slightly under ripe for preserving and freezing, and when fully ripe for eating there and then.

Plant broccoli, french and runner beans, courgettes, sweetcorn and pumpkins, as well as outdoor tomatoes, and continue sowing salad crops such as lettuce and radishes. Carefully hand weed around onions, or the smell of damaged roots will attract onion fly. Liquid feed them, if desired.

Strawberries should start to come thick and fast now – remember to water regularly, especially if in a pot, and feed weekly with a high potash liquid fertiliser. Watch out for birds who love the fruit as much as we do, best to cover plants with netting to keep them at bay.


Don’t worry too much if your lawn begins to look a little faded and dry – it will soon recover when any summer showers occur and, if they don’t happen, grass will usually survive until the autumn rains anyway. Save any water for plants that need it more. Only new lawns need to be watered, as newly laid turf will shrink if allowed to dry out.

Move garden furniture and children’s outdoor toys (in our house it’s the dreaded trampoline that causes issues!) regularly to prevent the grass drying out underneath.

Don’t forget to feed your lawn with lawn food for a boost such as Scotts Miracle-Gro Lawn Feed (1kg).


Continue watering everything regularly this month. Greenhouse crops such as cucumbers, tomatoes and peppers will suffer very quickly if starved of liquid, and irregular watering of tomatoes will cause the fruits to split as they swell. Keep pinching out the side shoots and tops of tomato plants, to avoid too many branches.

As the summer temperatures rise, dampen down greenhouse floors and surfaces to keep humidity high and help deter red spider mite and mildew disease. You may also want to shade your greenhouse to keep them cool and prevent scorch.


Keep it Local Events are here at Coolings on Saturday 23rd June 2018. The Farmers market is at Coolings on every fourth Saturday of the month from 9am – 1pm. You will find stalls selling fresh, locally sourced or made foods.

You will find plenty of fresh seasonal produce.

Our summer celebration of the English Rose...

This summer, Coolings are getting out the bunting (literally!) to celebrate one of the most well-known and cherished garden plants – the quintessential English Rose.  We will have a fantastic display of roses as well as a number of companion plants for roses on display in our plant area.  The team will be on hand to advise you how to care and maintain the plants so they flourish year after year. We will also have some great offers for our Coolings Family members.
