Feed Your Plants
Plants need food at the right time and in roughly the right quantities to deliver the best results for you in terms of flowers, leaves or fruit. Fertilizer is a concentrated form of food as opposed to bulky conditioners and organic manures. On bottles or boxes of fertilizer you will often see the N P K ratios where N = Nitrogen, P = Phosphates and K = Potassium.
Nitrogen encourages leaf growth so it is useful for Lawns, Houseplants, Spinach or other leafy vegetables. Good leave coverage is also important for photosynthesis so virtually all plants need nitrogen but too much can make a plant ‘soft’.
Phosphates are needed for healthy root growth in seedlings and beetroot or parsnips. Onions are big feeders on super phosphates or bone meal.
Potassium in the form of potash encourages flowering, fruiting and good colour. It is an essential component for feeding Tomatoes and other heavy feeders like Roses and Sweetpeas.
Bought Fertilizers
On my Baby Bio plant food bottle the NPK ratio is 10.6- 4.4 -1.7 which shows it is formulated for house plants which are often grown for foliage hence the high nitrogen content. Roots are also important in houseplants whilst flowers are often preordained at the growers prior to sale. If you are trying to get your plant to flower for a second or subsequent time you may want to use some tomato feed occasionally.
My other household fertilizer is a concentrated tomato feed 26- 17 -52 which is much more skewed to flowers and fruit. The higher these figures the greater the concentration of fertilizer and the more dilution you may need.
Organic fertilizers like blood, fish and bone and bone meal, hoof & horn and guano have a place in most gardens particularly for organic culture. Growmore is one of my staples for fertilising the garden prior to planting out and has equal proportions of NPK usually about 7-7-7.
