Evergreen plants retain foliage year-round but still shed and replace some leaves gradually as part of their normal growth cycle, rather than losing them all at once.

Deciduous plants shed all their leaves for part of the year (usually in autumn and winter), usually in response to colder temperatures or dry seasons, often producing seasonal colour before leaf drop.

Semi-evergreen plants sit between the two, keeping most of their foliage but losing some or all leaves briefly under cooler or drier conditions before quickly regrowing them.

When designing and planting your garden, it can be useful to know whether the soil is acid or alkaline, as different plants thrive in different soils. The soil pH is a number that describes how acid or alkaline your soil is. The soil pH scale will give you an idea of what soils a species will grow in.

Acidic soils have a pH below 7.0

Alkaline soils have a pH above 7.0

Neutral soils have a pH of 7.0

Chalky soil is alkaline and often contains visible pieces of chalk or limestone. It drains very quickly and can be low in nutrients, making it difficult for many plants to grow unless organic matter is added. Some plants, however, thrive in its free-draining, lime-rich conditions.

Rocky soil contains a high proportion of stones and gravel. It usually drains well but holds very little water or nutrients. Plant roots may struggle to establish, though hardy, drought-tolerant plants can adapt to it.

Sandy soil has large particles that feel gritty to the touch. It drains quickly and warms up fast in spring, but it does not retain moisture or nutrients well. Regular watering and the addition of compost can improve its fertility.

Loamy soil is a balanced mix of sand, silt, and clay. It holds moisture and nutrients well while still allowing excess water to drain, making it ideal for most plants. Loam is generally considered the best all-round soil for gardening and agriculture.

Clay soil is made up of very fine particles and feels smooth or sticky when wet. It retains water and nutrients well but drains poorly and can become compacted. With proper management, such as adding organic matter, clay soil can be very fertile.
