During the summer months when it is hot and dry the need for watering becomes crucial to aid successful establishment and in the winter when the soil is frozen the plants will not be in active growth either above or below ground and risk getting cold damage. The same is true on the stage or growth you can expect your plants to be delivered in and this will be directly related to the time of year and the season.\u003c\/p\u003e\n\u003cp\u003eWhen ordering through the year, here’s a summary of what to expect when receiving your plants:\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpring Months: \u003c\/strong\u003ePlants supplied in spring will be starting to show signs of active growth above and below ground.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSummer Months: \u003c\/strong\u003ePlants supplied in the late summer will be more advanced in size and flower stage\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eAutumn Months: \u003c\/strong\u003eIn the autumn plants will be changing colour, showing signs of leaf colour breakdown and be preparing to shut down for winter.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eWinter Months: \u003c\/strong\u003ePlants ordered and supplied during the winter months will be dormant and therefore may not be showing growth above the soil level or consist of bare branches with no leaves or bare roots with no soil. \u003c\/p\u003e\n\u003cp\u003eThese are all perfectly normal and natural for these types of plants growing in the northern hemisphere.  All will still have a very healthy root system that can be planted when the weather is favourable by keeping the new soil level equal to the pot level and therefore not covering the crown of the plant at all.  Planting during the autumn and winter months will allow for early establishment in the season and a bigger and better display throughout the main growing season.
