Sounds like you are using too much nitrogen and not enough phosphorus and potash in the fertilizers you use. Organic bone meal, which is sold at almost every DIY store and garden centre will help. On the package of fertilizer there will be 3 numbers such as 14-5-11. The first number is, of course, nitrogen which affects the density, fullness, growth of new roots and green colour. Remember the mnemonic "Up, Down, All Around". The "UP" is Nitrogen. The middle number is Phosphorus. This chemical promotes flowering, fruit formation, the cells in the leaves, roots and stems, seedling and root development and overall health and vigour. This is the "DOWN" in the equation. Finally, there is Potassium (or soluble Potash). This chemical assists in the formation of the plant's food supply (starches and sugars), promotes disease resistance, aids in the resistance against environmental stresses and overall hardiness. This is the "All Around". When you water excessively you leach these from the soil. Cut back to once every two to three days instead so the root sheaths are not compromised by root rot and nematodes. Hope this helps.
