Yes, concrete slabs can be laid on top of existing concrete slabs, as long as the extra height gained by doing this does not affect the damp-proof course, if the slabs are around a building.

All finished surfaces should lie at least 6-inches below the damp-proof course to prevent water breach. This is very important and is the only foreseeably problem with your question.

Plants are best split and/or relocated in the Autumn & Winter months, whilst the plant is dormant. Between Nov-Dec is ideal, as frosts make it very difficult to dig the soil.

I would not encourage your rabbit to eat garden plants in general. But there are few toxic plants growing in the average garden.

Animals generally know which plants are safe to eat and which are poisonous, without being overly concerned about their welfare. The main ones that may be of concern would be Aconitum (monkshood), Digitalis (Foxglove) and Taxus berries (Yew).

Watering is difficult to predict due to the varying climate we have. It is safe to assume that if it does not rain and the sun is particularly hot, then daily watering will be necessary, especially for south-facing borders. Otherwise, if you keep a close watch on your plants, their leaves will usually show you when they need water. Most of the year round, watering is only necessary for hanging baskets and pots. A layer of bark over the surface of the soil helps keep moisture locked in, which the sun baking only the bark, not drying the soil out.

It is a good idea to understand which plants in the garden are likely to need more water than others. Some plants may need more individual watering than others. The only real advice is to watch the weather and act accordingly.

You should not sterilise your garden soil and cannot buy products in the UK to do this.

Perennial weeds should be treated with a systemic weed killer, which will kill the roots of the weed, but will only act on coming into contact with green leaves and does not sterilise the soil. Bug sprays and insect/larval treatments also do not sterilise the soil, but will be effective in killing any pests that may be present.

There is a lot of choice of winter-flowering plants. Annuals/perennials like pansies, heathers, hellebores and primulas are very colourful. Bulbs like snowdrops and early daffodils will flower in late Winter and shrubs like Witch Hazel, winter-flowering Jasmine, Mahonia, Cornus mas and Viburnum bodnantense 'Dawn' all add something special to the garden at this time of year.

There are lots of ways of attracting wildlife into your garden. The main criteria is plants. A garden that has a range of trees, shrubs, perennials, climbers and annuals planted, will attract birds, insects, bees, butterflies and possibly hedgehogs. There are various animal and insect shelters that you can buy to encourage a particular type of wildlife to the garden and supplementary feeding always helps.Certain plants like Buddleja (the Butterfly Bush) and lavender also attract specific types of wildlife. In general, the more plants and trees a garden has, the greater the number and diversity of wildlife present.
