Prevention is always better - and cheaper - than the cure. Strong, healthy plants that are well tended will establish fast and resist disease. Your first concern should always be to improve soil structure and biology according to the plants' requirements (as a drastic oversimplification, trees and shrubs prefer more soil fungi, while annuals and herbaceous plants prefer more soil bacteria: be sure to follow Dr. Elaine Ingham's work to learn more), and water plants well in their first year while they settle in.
If the site is suited to the plant, if the ground is prepared well, if the plants are looked after properly after planting, if there are no pets or wildlife mucking about, if good garden hygiene is maintained, if you produce all the compost and mulch you need at home, and if the omens are auspicious, then you should rarely need anything from the product ranges below...
...If only. Every gardener knows that life is just not like that, so this is the place to buy strong plastic guards against vermin / magical forest creatures, chemicals to feed and protect your plants, and other such sundries: pretty much everything you need get started.
Planting accessories do three things: help new plants to establish and grow well in the early years, protect them from being eaten by animals and bugs, and prevent or cure diseases and other pests.
Rootgrow fungi make soil nutrients massively more available to your plants' root systems; it does so much good that it is considered as "essential" for hedging and large plants, and beneficial for all. Bonemeal is always good too.
Use an organic mulch mat or Mypex fabric to suppress the weeds, and you are set for a trouble free start for any hedge or tree planting. You can avoid using weedkiller on, or digging up, the densest ground elder and nettles by scalping them off at soil level and then covering the site for at about 16 months (two summers) with Mypex.
Protection includes spirals, which need bamboo canes, and tree guards, which need stakes. 60-80cms tall guards protect against rabbits, hare and muntjac. For roe deer and bigger, guards must be 120 cms tall, or you are wasting your money.
Disease will happen less when the right plants are used for the location, and when planting and aftercare are good. The list of chemicals available is dwindling, as is their efficacy, but we stock a range that covers most situations.
Always exercise caution and use protection when using planting accessories. Chemicals, whether pesticides or fertilisers (where too much of a good thing can really damage a plant), almost always have some toxic effect and should be handled and administered in accordance with their manufacturer's instructions. Eye protection is one of those things that one never needs - until that one time when one needs it badly.
Accessories that protect and support plants have been produced with low cost in mind. So handle them with care and thick gloves. Stakes and canes will have big splinters, plastic spirals will have sharp edges that can cut or stab, and so on.
