Keeping you safe
The safety of our visitors and staff remains our top priority. In England, wearing a face covering is a personal choice, although they are recommended in crowded and enclosed places.
We'll continue to provide hand sanitiser and stick to our high standards of cleanliness.

We are accepting orders and dispatching them as soon as we can. Current delivery times are up to 1-2 weeks.
Current volumes of orders with courier companies are very high, so occasionally there are delays regarding delivery. Also, orders with multiple boxes, may be separated in transit, but should be with you shortly.
Please note: if Government advice or our staffing situation suddenly prevents us from dispatching, then rest†assured that your plants will be reserved and cared for until such a time as we can dispatch again.†Orders are currently placed on this understanding.
Click & Collect FREE from nursery is available, please select at checkout
If you donít want to plant your recently purchased plants in this hot and dry weather, here are 3 tips for looking after them.
1.Keep in a sheltered spot, part shade, ideally out of the wind and not in full sun
2.Water when needed. Put the pots close together and if you can, place in shallow growing trays which will help retain any excess water
3.Herbaceous plants can be partly or fully cut back, reducing water stress. This will aid in their establishment by promoting new root and shoot growth once planted

On the day of delivery you will also receive an email and/or text to your mobile number, with a delivery time slot.
Why has my plant been cut back?
Traditionally, the mail order plant season has run from October to March. This was because many plants would be dormant during this time of the year and foliage would either be reduced or absent, making them easier to post.
Now, mail order runs all year round and this may mean we need to cut back some of your plants, particularly from April to October. Plants with tall flowering stems and lots of foliage may lose a great deal of water in transit and cutting back helps reduce this stress. Cutting back will not harm your plants but will help in their establishment by promoting new root and shoot growth once planted.
Why are there plants missing from my order?
Occasionally plants will not be sent due to poor plant quality. This should be noted on your invoice contained within your order and a refund will go back to your original payment method. Refunds will normally take 2-4 working days to process. Should you not have received your refund, please email us through our contact page
Are dogs welcome in the gardens?
Only assistance dogs are welcome in the gardens.† We recommend leaving dogs at home as our car park is very open with no shaded areas.
