Hampton Court Palace: RHS Hampton Court Palace Garden Festival Confirmed going ahead RHS Hampton Court Palace Garden Festival @ Hampton Court Palace
Hampton Court Palace Flower Show is the largest annual flower show in the World. Hampton Court has 34 acres of parkland so the flower show is able to spread out more than Chelsea. Unlike Chelsea where you can only purchase plants on the last day sell-off, at Hampton Court you can purchase plants and garden sundries on all days. In the last couple of hours in the afternoon of the last show day, a lot of the plants that have been in the display gardens are sold off at a reduced prices, so you may get a bargin. However, this also means that in late afternoon it's a bit frenetic and difficult to see the displays at their finest. 30 minutes by train from London Waterloo.

Welcome to the UKGardening Internet site.

The UKGardening web site has been running since 1998. The idea behind the site has always been to provide what we think will be interesting and useful information for the novice gardener.

Jobs to do in the garden this week.

  • Feed tomato plants fornightly with a liquid fertiliser (this must be diluted in water to prevent burning the plants)
  • Tie tomato stems to canes or stakes to prevent the weight of the fruit breaking the plant.
  • Tender herbs such as basil can be planted out in the garden now. Protect basil from slugs and snails.
  • Pond fish will eat more in the summer, feed them little and often, once or twice a day. If the food has not been eaten within 15 minutes, remove and dispose of the excess.
  • Plant up hanging baskets. More information available here.
  • Ensure that soil in hanging baskets and patio planters is kept moist. Remove fading and dead flower heads from plants, this will encourage new flowers. Feed hanging baskets and planters weekly with liquid fertiliser if a slow release fertiliser was not added when planting the basket.
  • We have probably now seen the last of the frosts. Summer bedding plants can safely be brought outside from the greenhouse or purchased from the Garden Centre.
  • Apple and pear trees will shed some fruit, this is known as the 'June drop'. This is quite natural, it's the trees way of restricting the amount of fruit that develop.
  • Move houseplants outside for some summer sunshine.
  • Plant tender perennials including pentstemons and salvias.
  • Depending on recent weather conditions and daytime temperature, gooseberries should now be ready to be picked.
  • Tomato plants can be moved outside. If growing them as 'cordons' nip out the side shoots
  • Continually nip out side shoots from upright (cordon) tomato plants. These reduce the amount of food available to fruit baring branches. If growing plants in the greenhouse, nip out the growing tip after the plant has produced 4-5 fruiting trusses, reduce this to 3-4 if growing tomatoes outside. See here, for more information: https://youtu.be/zFBgCBaFSnk
  • Cover strawberries and fruit bushes with netting to protect them from birds. Start to feed the plants weekly when the fruit starts to form.
  • Buy plants in strips or trays that are compact and sturdy, the compost that they are growing in should be moist. Try to buy plants in bud, with few open blooms.
  • Stake and tie perennials to prevent them being broken by wind and rain. Remove fading delphinium flowers to encourage a second flowering.
  • Paint shading on the greenhouse glass, or use shading to lessen the scorching effect of the sun and to keep temperatures lower.
  • Check the ties on climbers, flower stems and standard roses - the tops of plants can get very heavy when in full bloom or when wet.
  • Pinch out the growing tips of annuals and some perennials to create a stockier plant and to encourage more flowers More information here.
  • Sow hardy annuals in their flowering positions to fill any gaps in the border.
  • Check gooseberries for sawfly. Prune this year's growth back to 4-5 leaves (this shouldn't affect fruit as they appear on old wood).
  • Remove spring bedding plants and lift and store spring flowering bulbs (with the exception of snowdrops).
  • Trim hedges to encourage the branches to thicken up and to keep them neat and tidy.
  • Take soft wood cuttings from thyme. Thyme cuttings take easily, so they can be stuck in the soil or in pots. Remember that thyme likes full sun and hates to be grown in the shade.
  • Propagate marginal pond plants. Take short cuttings, remove lower leaves and push stems into pots of mud. Keep top of the pots just under the surface of the water.
  • Lots of tender plants can be grown outside in containers between May and September as long as the pot is big enough and they get enough water and the occasional feed.
  • The adult vine weevil, the number one garden pest, will be emerging from the soil as the temperatures rise.
  • Protect plants from slugs and snails with slug pellets, course grit or traps. Alternatively try to encourage birds, hedgehogs and frogs to your garden - all prey on slugs and snails. More suggestions to reduce slug and snail damage.
  • Regularly water trees and shrubs that were planted last autumn and winter. Their roots won't have had a chance to fully develop yet.
  • Cut grass weekly, long grass takes more nutrients out of the soil. It is also harder to cut and may leave yellow patches in the lawn.
  • Apply a weed and feed to established lawns. Water in with a hose after a few days if it hasn't rained.
  • Feed established roses, fortnightly, with a rose fertilizer, dead-head regularly and check for aphids and black spot.
  • Lift, divide and replant chives.
  • Weed and spread compost from the compost bin over the borders and vegetable patch. This adds valuable nutrients to the soil and acts as a mulch, to retain moisture and reduce weed growth. Ensure that the soil is moist before adding mulch.
