This Weeks Social Media Update.

WEEK 32: That Time Again.

Good afternoon Gardeners. Bit late with our update this week due to staff vacations. Social media is likely to be quiet next week for the same reason. Firstly can we say “Thank you” to all who attended our tours last week. General consensus was that they were enjoyable & informative. For those of you who missed out, we are sorry but there are no more planned for the imminent future, but we are not ruling them out completely. Yes… it is that time again. Bulb time that is. We have received a very early delivery of Spring bulbs. It is obviously too early to contemplate planting many of these, but we know that gardeners like to be prepared. They will be fine if stored in the dry until you are ready to plant out. We are unlikely to have a full selection for another couple of weeks, but there is a good range in stock to start you off including Alliums, tulips, daffodils, snowdrops, crocus etc. Also a few varieties for immediate planting including autumn crocus. Another weather warning this week for the south & south east. Lawns & #gardens in general are looking dry & dishevelled. Please prioritise your watering to plants that definitely require water such as annuals, hanging baskets, potted plants etc. water is a valuable (& sometimes expensive) commodity. Whilst we do not want you to lose plants, we also do not want you to bankrupt yourselves or waste water unnecessarily. Lawns for example, may look like a beige mess, but they will recover. So unless your livelihood depends on a lush lawn, consider if watering it is the best use of this valuable resource. Try to store & use grey water, such as bath & washing up water, around the garden. Let’s try to avoid hosepipe bans in this area by careful, wise usage. That is all for today. Keep yourselves safe in your gardens. See you again in a couple of weeks. 09/08/22

Site Plan

Finding your way around our site

Please note that, although this map is still relevant, we are now orerating under some covid19 distancing procedures which means that there are partial one-way systems in place. This restricts easy access between some areas.

Over recent years we have put a lot of effort into making our nursery as easilly accessible as possible. The entire sales area & car park have hard sufaces made from either concrete or tarmac. Outside pathways are wide and our sales beds are sturdy brickwork allowing customers to sit & take a rest if one of our benches is too far away or already occupied.

We feel that you will be able to navigate our nursery with ease, whether you are here for a leisurely browse or a calculated ‘in & out’ quick shop. Free copies of the nursery map (shown to the right) are available from our customer services desk, they also have a shop layout map on the back of them. Don’t forget, a member of staff will be more than happy to point you in the right direction.

We hope that you enjoy your visit.

Plant guarantee & refund policy

We are committed to ensuring that we sell excellent quality plants at what we deem to be reasonable prices. Many of our plants are grown here on site which enables us to maintain quality control to a very high level. Other plants are supplied by trusted companies, many of which have been in business for decades. We are always available to advise customers on the correct care for plants pre-purchase.

Because of this confidence in our product we do not offer a plant guarantee. However should you experience a problem with your plant within six months of purchase we will consider either replacement, credit note or advise you on a course of action to take to resolve the issue. Should the plant need to be returned it must be accompanied with valid proof of purchase (till receipt). We do NOT accept responsibility for plants damaged by weather conditions ( i.e. frost or extreme heat), or poor aftercare. A plant is a perishable good reliant on correct level of aftercare for survival. As such, after six months we relinquish responsibility for its nurturing & hand that duty 100% to the purchaser.

Refunds and exchanges

Should you change your mind about a ‘non plant’ product after purchase you may return it to us proving that the packaging has not been opened, the product has not been used, the product is still in saleable condition, with a valid receipt, within 28 days of purchase. Also, should the product be found to be faulty, it should be returned to us inside of 28 days with valid proof of purchase. Return or refund outside of 28 days may also be considered if the product meets the previous requirements stated. Plant returns should be within 5 working days. The plant will need to be in exactly the same condition as it was at the time of purchase and accompanied with a valid receipt. You will be offered credit note, cost equivalent exchange, or refund to the method of payment.This will be at the discretion of management.

If a product had been delivered by us its return is soley the responsibility of the purchaser. We will not offer a pick up service unless extreme circustances dictate that there is no other option. In such a case the purchaser may be liable for the cost of pick up. This will be at the discretion of management.

All refunds will be credited in the same fashion as initially received, i.e. if you paid by card, the refund will need to be issued to the same card.

We do not offer refunds or guarantees on any sale or stock clearance items.

Please keep your receipt as proof of purchase.

This does not affect your statutory rights.

Established in 1928

Not many Garden Centres can boast over ninety years of history, and yes, we have seen many changes over that period. Indeed change will continue as we strive always to supply the best in plants and facilities. One thing, however, will never change:

The core philosophy first introduced by Archibald John Mills way back in 1928 remains - the philosophy that built the company’s reputation, sustains it now, and will guide it in the future:

The best way to keep gardeners happy is to offer them plants of the highest quality, sold at reasonable prices.

Horticultural Trades Association.

We are proud members of the HTA, the Horticultural Trades Association, which is ‘the’ UK’s garden trades association. The HTA has, for over 100 years, promoted the interests of its members and the industry at large.

Being a member offers us various benefits and for you, the customer, the membership should provide you with some reassurance that we are an establishment of quality that takes its responsibilities to its customers seriously.

It also enables us to offer you access to HTA backed schemes such as the national gift vouchers which are redeemable at other HTA partner businesses across the country.

Perennial GRBS

We are also proud to say that our chosen charity is Perennial GRBS (Gardeners Royal Benevolent Society). We are a Perennial Partner which means that we make an annual contribution to this worthy cause whose sole aim is to help people in many branches of horticulture including arboriculture, farming, professional gardening etc during their hours of need. Occasionally we will attach a donate button to our Facebook posts which will enable you to donate directly to this charity should you feel so inclined. Our industry is enternally thankful to those who are able to donate even the smallest amount. To find out more about their work please feel free to visit their website https://perennial.org.uk/

Dog Friendly.

We are a dog friendly establishment. We are listed with www.dogfriendly.co.uk who’s aim is to provide a directory of dog welcoming businesses accross the UK. All that we ask of you as a dog owner is that your four legged friend is kept on a lead at all times whilst wandering around the Nursery and that you clean up after them should the enivitable ‘accident’ occur.

You may access all areas of the Nursery with your pet but we ask that on busy days, you avoid queing at the tills with them especially if they are not very good around strangers. This area can feel a little confined & we feel that for anxious dogs it is best avoided. Most of the time however, you are welcome to queue & pooch may even get a dog treat if they are allowed.

One thing that we frown upon severly is the leaving of dogs in cars whilst owners are shopping. There is no excuse for this here & we have been known to release pets from boiling hot vehicles by all means at our disposal.
