June Gardener's Calendar

Ah Blooming June! It’s wonderful to enjoy long hot summer days in the garden at this time of year, whilst watching the garden burst with growth, but many areas are prone to drought.  This is a good time to start a gardening notebook and make a list of those plants which withstand drought conditions. It’s a good idea is to use mulch to reduce the need for  watering.

There’s plenty to do in the garden during long summer days

 

 

Sowing and planting

If you haven’t done so, plant out summer bedding and make sure that you water them well to keep them moist during dry spells. Fill the gaps in your herbaceous borders with annual bedding.

Perennials such as Delphiniums and Lupins can be sown directly into drills outside when the seed heads have split.  Many varieties of winter bedding, such as wallflowers, pansies and ornamental cabbages should be sown between now and July for the  autumn and  winter seasons.

Sow Hellebore seed once they have ripened and been harvested.  Sow them immediately, whilst they are fresh.  Hellebores need a winter in the ground to encourage germination.

Plant autumn flowering bulbs such as Crocuses and Cyclamen.

 

Tidying your garden – Cut back, prune and divide

Now is time to prune yourspring flowering shrubs like early flowering clematis, Deutzia and Vibernum.

 

 

 

 

Dead-head Azaleas, Irises, Pansies, Violas and Roses. Also dead-head Rhododendrons when they have finished flowering, but be careful to remove the dead flower head, without damaging the new shoots.  Cut off the flowers from Lupins and Delphiniums as they fade.  Tall and floppy plants, such as Delphiniums, Hollyhocks and Peonies will need a stake to support them.  Also, you will need to tie in Climbing and Rambling Roses.  Any other trailing plants can be trimmed to encourage fresh growth and new blooms.

Hybrid Tea Roses can be disbudded now, remove smaller buds from the cluster that forms at the shoot tip and leave the largest central buds to develop into large show stopping blooms.

 

 

June Garden Maintenance

Don’t neglect container plants, feed them every 2-4 weeks. 

Water hanging baskets and containers, as they will dry out faster than your beds, but try to use collected rainwater or grey water, wherever possible.

Keep on top of the weeding. You can use a trowel or hand fork for deep rooted perennial weeds like dandelions, but using a hoe is a great way to quickly slice into the soil and remove the weeds.  Hoeing on a sunny day is best as you can leave the weeds to shrivel up and die quickly.

Sweet Peas love to grow up wigwams.  Gently tie plants into supports to encourage Sweet Peas to climb.   

Pests are on the increase this month, so check Roses for signs of blackspot and aphids.

 

Protect

Vine Weevil larvae can be a serious pest to containerised plants and they will become active this month.

Try biological control for Vine Weevil – see http://www.jerseyplantsdirect.com/Pages/ProdDetail.aspx?id=2177 – safe for your vegetables too!

 

Aphids multiply rapidly this month and into the summer.  Remove early infestations by hand to prevent the problem getting out of control.

Protect vulnerable plants like Lily, Delphiniums and Hostas, from slugs and snails.

 

Vegetables

Sow Beetroot, Lettuces, Carrots, French and Runner beans, Peas, Spring Onions directly into the warm soil. 

Plant out vegetables that you have started indoors such as Courgettes, Cucumbers, Tomatoes. Harden them off before planting them out.

Harvest Lettuce, Radish and other Salads and Early Potatoes and pull up baby Beetroot.

Tend to Tomatoes by removing the side shoots on Tomato plants as soon as they appear at the base of a leaf.
