Garden pest identification. Daylily Hemerocallis gall midge.

Garden pest, Hemerocallis gall midge

Hemerocallis gall midge infestation

Day lilies – Hemerocallis species and cultivars have a parasitic pest called the Gall midge Contarinia quinquenotata

It’s been gradually spreading through the UK since 1989.

There is no control for the pest other than picking off the infected flower buds and destroying them.

Don’t put them in the compost bin as they will pupate and emerge next year.

Daylilies Hemerocallis gall midge pest I put the infected buds on a table in the sun thinking that this would kill the larvae but instead the maggots wriggled out and went into early pupation.

 Burning the buds is the sure way of destroying these maggots. 

 Contarinia quinquenotata

The adult fly is tiny and lays hundreds of eggs in the developing flower buds.  The white maggots grow to about 2-3mm. When ready to pupate the larvae crawl out of the flower bud and fall to the ground where they bury themselves in the soil, pupate, then emerge as adults flies the following year.

Keeping slugs and snails off your hostas

June 22, 2008

Hosta in containerOne way to keep slugs and snails off your hostas is to grow them in containers.

Put gravel around the base of the container and another layer around the plants.

A simple method and it works quite well without the use of slug pellets.

The gravel around the base of the hosta helps keep the roots cool and prevent moisture loss


Sell by dates on grow bags

June 20, 2008

Tomato after a couple of weeks in a grow bagI think that grow bags should have sell by dates.

It’s very frustrating that once you’ve grown your prize seedling and plant it in a grow bag that it writhers and dies because of old mouldy content of a grow bag.

I know that garden centres need to make a profit, but the whole purpose of a grow bag is to grow plants. Food items have sell by dates – so how about grow bags.

 This tomato plant was healthy when grown in a pot but became weak after a couple of weeks in a grow bag

I’m interested in your comments


Keeping your garden interesting isn’t difficult or expensive if you choose the right plants.

June 18, 2008

Adding colour and texture plants will keep your garden looking interesting at different times of the year and individual. It’s not difficult or expensive; it’s just knowing which plants to choose.

Ideally gardens should have some plants of interest at different times of the year rather than have a splash of colour in spring and then not much for the rest of the year.

There are so many plants to choose from which suit every colour, height, aspect and season.

 

I use shrubs to give my garden year round shape and colour and then position plants which come into flower, leaf colour, bark, berry or texture to add interest at intervals throughout the year.

 

Some plants are small plants for the front of the border like the viola ‘Bowles Black and iris reticulata ‘Pixie’

small plant with black flowers

Some have colourful flowers like the Arisaema colourful flower or the Aloe Aloe

 

Some have leaf colour like this Acer Attractive leaves 

Some add texture Cordyline australis

I’ve designed a simple MAC & PC garden plant CD-Rom to help you find plants by colour, aspect, height and month to suit every garden aspect and seasonal need.

It’s not expensive and can help you create a beautiful garden using the right plants to suit your garden conditions. The latest garden software version has 3,500 plants and over 9,000 photographs. Each plant is accompanied with plant care and illustrated pruning advice.

Elderflower cordial recipe

June 9, 2008

Elderflower cordial Now (June) is the perfect time to pick elder flowers to make Elderflower corial. Best not pick flowers close to a road or railway track due to pollution.

Pick the flowers when they’ve opened i.e still with lots of pollen. Flowers that have not opened or have passed over do not give good flavour.

 

Cut 30 heads of elderflowers into a large sterilised bowl or bucket, add 2 sliced lemons (non waxed ones) and 1.5 kg of Sugar, mixed with 50g citric acid (you can buy this from the chemist). Pour on 1.5 litre of boiling water and leave for 5 days to mature, stirring everyday. Elderflowers and lemon

 

Then strain with a seive to seperate the juice. Elderflower cordial straining juice   Elderflower collecting concentrate 

and pour into clean and sterilised bottles. Pour the Elderflower in to bottles

 

The Elderflower cordial concentrate can be kept in screw top bottles for about a year. The 30 flower heads made this much cordial Home made elderflower cordail

 

Serve mixed with sparkling water, slices of lemon and ice – delicious
